Now, new research from University of Guelph has led to the development of a product that extends the shelf life of fresh fruits by days and even weeks, and it is showing promise in food insecure regions around the world.
“In people and in fruit, skin shrinks with age — it’s part of the life cycle, as the membranes start losing their tightness,” said Jay Subramanian, Professor of Tree Fruit Breeding and Biotechnology at the University of Guelph, who works from the Vineland research station. “Now we know the enzymes responsible for that process can be slowed.”
The secret, according to Subramanian, is in hexanal, a compound that is naturally produced by every plant in the world. His lab has developed a formulation that includes a higher concentration of hexanal to keep fruit fresh for longer.
Subramanian’s research team began experimenting with applying their formula to sweet cherry and peaches in the Niagara region. They found they were able to extend the shelf life of both fruits and spraying the formula directly on the plant prior to harvest worked as well as using it as a dip for newly harvested fruit.
“Even one day makes a huge difference for some crops,” Subramanian said. “In other fruits like mango or banana you can extend it much longer.”Once the formula is available on the market, Subramanian sees applications on fruit farms across Ontario, including U-pick operations, where an extended season would be beneficial. But the opportunities could also make a significant impact on fruit markets around the world.
Subramanian’s research team was one of only 19 projects worldwide awarded an exclusive research grant from the Canadian International Food Security Research Fund, a program governed by the International Development Research Centre and funded through Global Affairs Canada.
The team used the funding to collaborate with colleagues in India and Sri Lanka on mango and banana production. Mangos are one of the top five most-produced fruits in the world, with 80 per cent of the production coming from South Asia. After more than three years, researchers learned that by spraying the formula on mangos before harvest, they were able to delay ripening by up to three weeks.
“A farmer can spray half of his farm with this formulation and harvest it two or three weeks after the first part of the crop has gone to market,” Subramanian said. “It stretches out the season, the farmer doesn’t need to panic and sell all of his fruit at once and a glut is avoided. It has a beautiful trickle-down effect because the farmer has more leverage, and the consumer gets good, fresh fruit for a longer period.”
The team is at work in the second phase of the project applying similar principles to banana crops in African and Caribbean countries, and hopes to also tackle papaya, citrus and other fruits.
The formula has been licensed to a company that is completing regulatory applications and is expected to reach the commercial market within three years.
According to the Idaho Farm Bureau Federation, every spring farmers plant more than 320,000 acres of potatoes valued at between $550-$700 million. Yet unbeknownst to most consumers, roughly 30 percent of the potatoes harvested spoil before they reach a grocery store shelf.
Boise State University researchers Harish Subbaraman, David Estrada and Yantian Hou hope to change that.
In a recently awarded one-year $413,681 Idaho Global Entrepreneurial Mission (IGEM) grant, Boise State is collaborating with Idaho State University and industry partners Isaacs Hydropermutation Technologies, Inc (IHT) and Emerson to develop a wireless sensor network that would be able to detect temperature, humidity levels, and carbon dioxide and ammonia levels in real time, to help with early detection of rot.
The cloud-enabled sensor system will feature three-dimensional hot spot visualization and help predict on-coming rot or deteriorating quality of stored potatoes. This will allow owners to use the real-time sensor data, along with a miniature air scrubber system IHT is developing, to respond to potential problems quickly, as they develop.
“The current problem is, there are no sensors that can do early detection of rot,” said Subbaraman, an assistant professor of electrical engineering. “But if you can identify rot at an early stage, you can prevent crop loss on a large scale.”
“Rot spreads on contact. The way the system works now is, a farmer walks into their facility, smells rotten potatoes and that’s it,” added Estrada, an assistant professor of materials science. “But our sensors can detect parts per million, or even parts per billion, and can tell us in exactly which bin the sensor is detecting rot. That way, farmers can go out, pull out a few rotten potatoes and save the rest of the batch.”
Estrada explained that the cost of printing sensors could be as low as a few dollars apiece. Not only would the monitoring system hopefully prevent waste, it could help preserve the quality of potatoes in the facility.
Subbaraman and Estrada plan to have their sensors tested in a facility by the end of their year-long grant cycle by working with industry partner Emerson PakSense. But Estrada points out that this project has been three years in the making and will continue long past the IGEM grant.
“The College of Business and Economics and the College of Engineering have been invested in building a printed electronics community in Idaho for several years,” Estrada said. “Most recently, our Advanced Nanomaterials and Manufacturing Laboratory has partnered with the NASA Ames Research Center, Air Force Research Labs, and American Semiconductor to develop flexible electronics technologies.”
Subbaraman noted, “We’re also very interested in partnering with others interested in this technology. It’s a great economic impact for the state and we see that growing in the future.”
Not only would the cloud-enabled wireless sensory system save Idaho farmers millions in revenue, it could have a billion-dollar impact on the national potato industry and help address larger socio-economic issues such as food scarcity in parts of the world.
“The benefit of this system is it’s extremely low cost,” Subbaraman added. “This dual detection and air scrubbing system could later be extended to other stored crops as well.”
Lingonberries are already popular in Scandinavian cuisine where they are used in sauces for chicken and pork, as well as in muffins and breads.
Small, tart and slightly sweet, they are native to British Columbia, Manitoba, and Atlantic Canada and have the potential to become a valuable crop for Canadian growers.
The lingonberry is closely related to the blueberry and cranberry, which are also high in anti-oxidants. The benefits of lingonberries and their juice may go even further: preliminary studies in Sweden suggest there is potential to help prevent weight gain, and to help prevent high sugar and cholesterol levels.
But there’s more! New research from Dr. Chris Siow, Research Scientist with Agriculture and Agri-Food Canada and principal investigator with the Canadian Centre for Agri-Food Research in Health and Medicine (CCARM), located at St. Boniface Hospital, is showing that lingonberries may also contribute to healthy kidneys.
Here’s how: during kidney surgery, including transplants, kidneys experience low oxygen, and when oxygen is returned to the organ there can be inflammation and damage. In tests using lab rats Dr. Siow’s research team fed one millilitre (the human-equivalent of one cup) of Manitoba lingonberry juice daily for three weeks to one group and none to another prior to kidney surgery.
The rats that had consumed lingonberry juice had improved kidney function, reduced kidney stress and reduced inflammation following the operation in comparison to those that had none. These results also showed that as the concentration of lingonberry increased, the protective effect also increased.
“Overall, the research data obtained from these studies is very promising and we are encouraged that we may have a commodity that has positive impacts on human health,” said Dr. Siow. “We plan to continue with our studies to validate the early results and look for additional benefits the berry may provide.”
Meanwhile across the country, research on the lingonberry plant itself is taking place. Work with lingonberry production and germplasm enhancement is being done at AAFC’s St. John’s Research and Development Centre (NL) under the leadership of Dr. Samir Debnath. He has been working in collaboration with Dr. Siow.
“Lingonberry will be a potential health-promoting berry crop for Canada” said Dr. Debnath who developed a number of promising hybrids between European and Canadian lingonberries.
Dr. Debnath is also working in collaboration with the Newfoundland and Labrador provincial government and with Newfoundland and Labrador (NL) growers for growing lingonberry hybrids under field conditions.
Drs. Debnath and Siow not only believe that this berry will be beneficial to consumers – especially when studies like his continue to produce positive results – but that lingonberries will also be of interest to growers as they may provide new business opportunities.
- Lingonberries contain more anthocyanins, the pigments that give them their red colour, per gram than most commonly consumed berries (i.e., blueberries, cranberries). It is these compounds that may provide health benefits.
- Lingonberries are rich in vitamins and minerals.
- Lingonberries can be found growing wild in the northern regions of Canada. Research shows that the lingonberries grown in Northern Manitoba contain the highest levels of antioxidants.
We spoke to CIP sub programme science leader for integrated crop and system research, Jan Kreuze, and NASA Ames geobiologist and researcher, Julio Valdivia–Silva, about their otherworldly project.
Valdivia–Silva says the partnership between CIP and NASA came about through the organisations' mutual interest in growing crops under difficult conditions.
"The initiative came from CIP, with the intention of solving problems around cropping in desert areas as a result of climate change and desertification," Valdivia–Silva explains. "Meanwhile, NASA was interested in the project for the need to grow crops in future human colonies outside Earth."
But why potatoes? Kreuze says this is down to the minimal amount of water potatoes require per kilogram grown compared to other major cereals, as well as their ability to withstand a wide range of environmental conditions, their nutritional value, and their fast growing, high yield nature.

Almost 200 weed scientists across the U.S. and Canada participated in the 2016 survey, the second conducted by WSSA.
A 2015 baseline survey explored the most common and troublesome weeds in 26 different crops and noncrop areas.
The current survey ranks the following weeds as the most troublesome or the most common among broadleaf crops, fruits and vegetables:
TOP 10 WEEDS IN BROADLEAF CROPS, FRUITS & VEGETABLES
- Palmer amaranth
- Common lambsquarters
- Horseweed (marestail)
- Morningglory (ivyleaf, pitted, tall)
- Waterhemp (tall, common)
- Nutsedge (yellow, purple)
- Common ragweed
- Giant ragweed
- Nightshade (eastern black, hairy)
- Common lambsquarters
- Foxtail (giant, green, yellow)
- Morningglory (ivyleaf, pitted, tall)
- Palmer amaranth
- Redroot pigweed
- Waterhemp (tall, common)
- Horseweed (marestail)
- Common ragweed
“Weed scientists have confirmed multiple cases of herbicide resistance in all six of these weed species, except for the morningglories where there is suspected resistance to glyphosate,” says Lee Van Wychen, Ph.D., science policy director for WSSA. “While each of these species has evolved traits that make them widespread and tough competitors in broadleaf crops like soybeans and cotton, there is no question that their difficulty to control with herbicides has pushed them to the top of the list in this survey.”
WSSA also sorted the survey data to produce the following crop-specific results, shown below by crop, most troublesome weed and most common weed, respectively:
- Alfalfa: Canada thistle; dandelion
- Canola: kochia; wild oat
- Cotton: Palmer amaranth; morningglory (ivyleaf, pitted, tall)
- Fruits & nuts: field bindweed; horseweed (marestail)
- Peanuts: nutsedge (yellow, purple); Palmer amaranth
- Pulse crops: common lambsquarters; common lambsquarters
- Soybeans: horseweed, waterhemp (tall, common); waterhemp (tall, common)
- Sugar beets: common lambsquarters; common lambsquarters
- Vegetables: nutsedge (yellow, purple); common lambsquarters
Common lambsquarters is widely distributed across the northern half of the United States and southern Canada. It is not surprising that it ranked as the most common weed in sugar beets, vegetable crops and pulse crops, such as dry edible beans, lentils and chickpeas.
WSSA plans to conduct habitat-specific weed surveys annually. The 2017 survey will focus on weeds in grass crops, pasture and turf, while the 2018 survey will focus on weeds in aquatic environments, natural areas and other noncrop settings.
The 2016 survey data is posted online at http://wssa.net/wssa/weed/surveys.

The Brown Marmorated Stink Bug is an invasive insect that damages various fruit and vegetable crops including apples, tomatoes, beans and many others.
While the insect hasn’t been detected in the province, scientists are expecting its arrival in the next few years.
To get ahead of the game, Dr. Moffat is setting traps in key locations across the province to try to determine if the pest has made its way to N.B.
Originally from Asia, the Brown Marmorated Stink Bug was first detected in the U.S. in 2001.
Since then, the pest has established populations in many U.S. states as well as B.C., Ontario and in 2016 it was discovered in Quebec.
While there are other stink bugs native to this region, the Brown Marmorated Stink Bug has distinct markings that give it away.
These pests have two obvious white bands on otherwise dark antennae, inward-pointing white triangles between dark markings along the edge of the abdomen, and a smooth edge along the pronotum or "shoulders".
They are mottled brown-grey dorsally and a have a pale underside. Legs have faint white bands.
The Brown Marmorated Stink Bug can be found in homes or storage sheds over the winter and start making their way outside in the spring. Moffat is asking New Brunswickers to be our citizen scientists this season and be on the lookout for this pest.
Campers and travellers spending time in the U.S. or central and western Canada this summer are asked to check their luggage and trailers for signs of the pest before returning to N.B.
Transparency in our food system is no longer optional; so farmers and ranchers through to the largest food companies need to know more on how to effectively earn public trust in our food and how it’s grown.
“The CCFI Public Trust Summit is not ‘just another meeting.’ It’s an experience for you to come and learn from the entire food system,plus help shape the path forward for earning trust in Canadian food and farming,” says Crystal Mackay, Canadian Centre for Food Integrity.
This year’s theme “Tackling Transparency — the Truth About Trust” kicks off with a full day of Experience Alberta farm and food tours on September 18th, capped off by an evening celebrating the “Science of the Six-Pack.”
Brew masters will be on-hand to walkthrough how local barley, hops, yeast, and water combine to make pints of beer.
The second day’s highlights include:
- Release of the 2017 CCFI public trust in food and farming consumer research
- World class speakers with a variety of perspectives and insights on transparency and trust
- A lively consumer panel of millennials sharing exactly what they think about food and farming
The inaugural CCFI Public Trust Summit, held last June in Ottawa, sold out with an incredibly diverse representation from food companies, retail and food service, government, academia, farmers and food influencers, like bloggers and dietitians.

The demonstrations were conducted in the Plant City area of Hillsborough County, Florida, the main winter strawberry growing region in the U.S. which produces around 20 million flats of strawberries on 11,000 acres every year.
Three influential growers who combined, control about 30 per cent of the production in the region, expressed interest in gauging how the BVT System, consisting of a bumble bee hive with proprietary dispenser technology through which BVT's proprietary plant beneficial microbe BVT-CR7 is delivered to crops using bumble bees, could improve the productivity of their farming operations and how it could be incorporated into their crop production practices on a commercial scale.
The demonstration fields were assessed for both (a) control of botrytis gray mold, a costly disease in strawberries which causes the fruit to rot and reduces the shelf life of berries, and (b) the ability to improve marketable yield.
"These are significant results and confirm that the positive results we have seen in the numerous field trials we have done over the last couple of seasons, also apply in commercial fields under real-life conditions," stated Ashish Malik, CEO of BVT. "We have been able to demonstrate that the BVT system improves yields 1) in the presence, or even in the absence of botrytis disease pressure, which is significant since it shows our system brings value to growers regardless of the severity of the disease which will follow a natural cycle from year to year; 2) with full or reduced amounts of chemical fungicides giving the grower flexibility in how they want to use the system."
Jay Sizemore, owner of JayMar Farms where one of the demonstrations was done said "These are some encouraging results. Growers are always looking to improve what we do since our margins keep getting thinner. I thought the BVT system had a lot of promise when I first learnt about it which is why I was eager to try it, and I am pleased to see my thoughts confirmed with the positive results from the demo. It is especially compelling since this is an all-natural way to seemingly improve productivity of the berry crop."
Mr. Malik added "It is notable that, based on the yield increases that have been recorded because of using the BVT system on the three test sites, if the entire Plant City strawberry crop was treated, it could theoretically lead to the production of 1.2M to 5.8M additional flats of strawberries, or put another way, generate between $10 million to $50 million in additional revenue for the growers in the area. We are very thankful to our three grower partners for their cooperation and look forward to continuing our discussions with them on how best to integrate our system into their long-term farming operations."
"Large-scale commercial demos represent the final pre-commercial stage in the well-established path to commercialization that forms the basis of any major adoption of new on-farm technology. We expect these latest demos to further accelerate demand for our technology and allow us to successfully complete our go-to-market plans," said Mr. Malik.
In the first demonstration, conducted on 40 acres at JayMar Farms, the field was divided into three sections: one section was treated with chemical fungicides alone, the second section was treated with the BVT system and the same chemical program used in the first section, while in the third section the BVT system was used with a 50 per cent reduction in the chemical sprays.
- The two sections with the BVT system had statistically significant reductions in incidence of botrytis gray mold (3 per cent vs 13 per cent)
- The section where the BVT system was used with a 50 per cent reduction of the chemical fungicides had the best marketable yield, 26 per cent better yield than chemicals alone in direct comparisons
- The section where the BVT system was used together with the full chemical program produced a 6 per cent higher yield than where the chemicals were used alone in direct comparisons
- All sections of the field had low levels of botrytis gray mold
- The two sections where the BVT system was used produced 6 per cent and 24 per cent more marketable yield respectively than chemical fungicides alone
- On average for the season, plants in the sections where the BVT system was used produced 11 per cent more berries per plot compared against the chemical fungicide section
- Both sections of the field had low levels of incidence of the botrytis disease
- The section with the BVT system had a 29 per cent higher marketable yield across two observations when compared against the chemical only section
In the next six months, the Company will complete its go to market planning for the commercial launch including finalizing the business model, pricing and distribution partnerships, and is planning trials in additional crops and countries, including sunflowers in the U.S. and in strawberries and tomatoes in Europe.

“They’re very tranquil,” she says.
Why wouldn’t they be? Inside their cage, they enjoy spa-like conditions with all the sunflower seeds and nuts they can feed on, the warmth of the sunlight coming through the window beside them and a few house plants to make it feel like the outdoors, though they’re in a lab.
Young offspring clutch the walls of a separate cage inside what appears to be a refrigerator but instead is a warming chamber.
Such special treatment for the brown marmorated stink bug, which farmers despise and homeowners often flick out of the way when they discover them indoors during the cold months.
Thriving on a range of fruits and vegetables, the marmorated stink bug has damaged or destroyed enough crops in Ohio and across the United States to get the attention of entomologists nationwide.
Welty, an Ohio State University Extension entomologist, is involved in a 15-state study to determine the best, and ideally natural, way to get rid of the marmorated stink bug. The study is one of several being done on stink bugs through Ohio State’s College of Food, Agricultural, and Environmental Sciences.
The brown marmorated stink bug is a foreigner to the U.S., and in the absence of natural predators here, its populations are exploding, particularly in the mid-Atlantic region. Arriving in the U.S. from China, the grayish brown bug was first detected in Allentown, Pa., in 2001. Six years later, one was reported in Ohio.
How the first brown marmorated stink bug got to the U.S. is unclear, but often it is carried through boxes or packages, a hitchhiker of sorts, Welty said.
“They like to nestle down into protected, narrow spaces, and that’s often present in packing materials,” she said. “That’s why they’re known to go in cargo and hang out.”
Three years ago, a grower in eastern Ohio ordered a shipment of snow fencing, the perforated plastic fencing that comes in large rolls. When the grower unrolled the fencing sent from Pennsylvania, he found live stink bugs sprinkled throughout.
From Welty’s colony of marmorated stink bugs, she takes the eggs and places them outside the lab on plant leaves. Two days later when she retrieves them, she hopes some have been attacked by the bug’s natural predator, the tiny Trissolcus japonicus wasp. Also a native of China, the wasp was detected in the United States in 2014 and has since been found in eight states but not yet in Ohio. And nowhere in the U.S. is it plentiful – at least not plentiful enough to keep down the marmorated stink bug population.
“The wasp appears to be spreading on its own, but it’s so early on in the introduction of the wasp that we really don’t know,” Welty said.
Welty and entomologists across the U.S. are hoping to happen upon some T. japonicus wasps in their states.
“We’ve known for a number of years now that this one species of wasp would be great to have,” Welty said. “The stink bug is a terrible pest in agricultural crops, and we want to know how to control it with more sustainable methods than just spraying a lot.”
Stink bugs of any species can be tricky to spot outdoors. They hide well – stationing themselves on the underside of leaves and the backside of flowers.
A new petition on Change.org is calling on Canadian food retailer Sobeys and its subsidiaries, such as Safeway and FreshCo, to adopt an “ugly” produce line.
According to the page, about 20 per cent of all produce in Canada is thrown away before it reaches grocery stores “mostly due to cosmetic standards from large grocers.”
That includes fruit or vegetables that are bruised or have an unusual colour or shape. READ MORE

In the poll, 71 per cent of Quebecers believe independent restaurateurs should have the right to import wine and sell it directly to consumers.
"These numbers show a solid majority of people from Quebec recognize the huge hurdles to wine imports, and the negative effect it has on consumer choice and product diversity," says David Lefebvre, Restaurants Canada's Vice-President Federal and Quebec.
Currently, direct imports from producers are sometimes allowed, but the taxes, levies and paperwork required make it almost impossible to do so efficiently.
Restaurants Canada has long-advocated against trade barriers between provinces, and the MEI poll results supports its stance. READ MORE
Gallegly and his research partner, Mahfuz Rahman, released two new varieties of tomato.
The tomatoes, identified as West Virginia ’17A and West Virginia ’17B, were obtained by breeding the tomatoes known as the West Virginia ’63 and the Iron Lady.
Gallegly developed the W.Va. ’63 tomato in the 1960s as a tomato resistant to late blight, a plant disease usually caused by fungi. The Iron Lady tomato, developed by Martha Mutschler-Chu of Cornell University, also resists late blight but also Septoria lycopersici, a fungus that causes spotting on leaves.
Gallegly said the stink bug, specifically the marmorated stink bug, is the likely cause of Septoria increasing on tomatoes.
“We just crossed the two tomatoes and in the second generation in the field, we made selections for fruit type, yield, taste and so on,” Gallegly said. “So we came up with two new varieties.”
Through their evaluation, the two tomatoes should have a higher tolerance to Septoria leaf spot and better fruit quality.Tomatoes are a specialty of Gallegly, who turns 94 this month.
He came to the University in 1949 as an assistant professor and was hired to become the vegetable plant pathologist for the state.
He spent his first fall and winter at the university collecting varieties of tomatoes and potatoes. The next year, he planted varieties of the two vegetables and discovered late blight was severe that year. So much so that he had zero tomato yield.
“That told me I had to go to work on trying to control this disease,” he said.
After 13 years of screening the vegetables and research, he came up a new tomato in 1963 — the West Virginia ’63.
Gallegly officially retired from the University in 1986 but earned emeritus status and kept a presence at the college to continue research and teaching.
On March 24, the two new tomatoes were unveiled during the annual Potomac Division of the American Phytopathological Society meeting in Morgantown. READ MORE

Collaboration on the project started in 2015 and has resulted in the joint patent entitled "Substituted cyclic amides and their use as herbicides." The new herbicide has entered into the pre-development stage and is expected to be launched in 2023.
“We are very pleased that our collaboration with Syngenta has extended into a joint research project for a new herbicide chemistry class,” said Timothy P. Glenn, president of DuPont Crop Protection. “Partnerships for the advancement of crop science and development of crop protection solutions help growers realize the potential in their fields.”
“We are excited to be working again with DuPont on this herbicide research and development project,” said Jon Parr, president for crop protection at Syngenta. “Success in this field will bring much needed new technology to farmers in the increasingly challenging area of weed management, including resistance.”
Sept. 29, 2016 - Ag-Grid Energy LLC, based in Kennett Square, PA, working with RCM Digesters, located in Berkeley, CA, has selected the Anaerobic Digestion Lab Test Network (ADLTN) to perform a set of four lab tests on solid mushroom substrates (SMS) including biomethane potential (BMP) testing.
December 9, 2015 - Researchers from Michigan State University (MSU) have received a $173,151 grant from the U.S. Department of Agriculture National Institute of Food and Agriculture to study novel, non-spray control methods for invasive fruit pests.
The two-year project will examine the use of small nylon pouches that hang from trees and/or bushes. The pouches are treated with insecticides and filled with attractants such as pheromones or food to lure and kill the insects on contact.
Organic pest management expert Matthew Grieshop, tree fruit entomologist Larry Gut and postdoctoral research associate Juan Huang will examine the use of these pouches on three pests:
- Spotted-wing drosophila is a small vinegar fly native to east Asia that was first detected in California in 2008. Since then, the pest has spread across the country, damaging tree fruit crops and costing growers an estimated $700 million per year.
- Brown marmorated stink bug, also from Asia, attacks fruit, vegetable and ornamental crops in Michigan and around North America.
- Codling moth, native to Eurasia, is the primary pest facing the apple industry in Michigan.
The project will allow researchers to determine which attractants work best and how long each pest must be in contact with the insecticide to receive a lethal dose. Grieshop indicated that the project model was taken from research conducted with mosquito netting.
“We’ve been working on the attract-and-kill project for three seasons,” Grieshop said. “It was originally funded by MSU’s Project GREEEN [Generating Research and Extension to meet Economic and Environmental Needs] and commodity groups. The first season was really the development and testing of the technique. The second was working with various pests such as Japanese beetle and Oriental fruit moth. It has worked well, and we’ve gotten great data. We hope to have the same type of success with these other pests.”
Laboratory testing and fieldwork will be conducted. Researchers must determine in the lab how long each species needs to be exposed to the insecticide to suffer 100 percent mortality. Then, in the field, cameras will monitor wild insects’ interactions with the nylon bags.
The initial work isn’t compatible with organic farming because the test insecticide is not National Organic Program (NOP)-compliant. However, eventually the researchers want to determine if NOP-compliant insecticides could be substituted.
“My hope is that, by expanding our attract-and-kill technique to more pests, we can identify some key insect behavioral characteristics that can predict whether this type of approach is likely to succeed for many pests,” Grieshop said. “The most exciting aspect of this pest management technique is that, by bringing the pest to the insecticide rather than broadcasting the insecticide and hoping that the insect will contact it, we are developing pest management tactics that are both economically and environmentally conscious.”
