February 9, 2018 – For growers, a fundamental element of integrated pest management is knowing what pest and beneficial species are in your fields. But what if there’s an insect and no one knows if it’s good or bad?

That was the situation for apple growers in Washington when it came to the European earwig. The bugs were there, but no one knew if they helped growers or harmed their crop.

In 2014, the same year Robert Orpet began his doctoral program, there was a bad outbreak of woolly apple aphids in Washington orchards.

“The trees looked like they were covered in snow,” he remembered. “It was very visible, and people don’t like that.”

Orpet was part of an interdisciplinary team looking into the aphid, and one of his tasks was to interview growers about natural predators. Although there was some scientific literature in Europe that suggested earwigs were aphid predators, very few growers named them as important beneficial natural enemies.

Many, in fact, said they thought earwigs were pests that damaged their apples because they’d found earwigs in cracks in their fruit.

Orpet had an idea why grower’s perceptions and the scientific literature might differ.

“Earwigs are active at night, so people don’t see them eating aphids,” he said. “They also move into tight spaces, a behavior called thigmotaxis, so it wasn’t clear if the insects were causing the damage to the fruit or just sheltering in the damage.”

Another possible explanation was that the European literature was just wrong.

“What literature there was tended to be observational and anecdotal,” he said. “The question had never been tested experimentally in a realistic field situation.”

So, with a graduate student grant from the Western Sustainable Agriculture Research and Education program, Orpet designed an experiment to test the positive and negative effects of earwigs in apple orchards.

He set up experimental sections in four different orchards and, in each section, either added earwigs, removed earwigs or left them alone. Because of the insects’ small-space-seeking behaviour, they are easy to trap in corrugated cardboard rolls and move from one place to another.

The results were pretty clear.

First, earwigs are aphid predators. Not only did his numbers support that, he captured video of a single earwig completely consuming an aphid colony. (See it at youtube.com/watch?v=sSFakIgkfMI)

“We measured it in a few different ways, but the maximum amount of woolly apple aphids was two to three times greater in the trees with fewer earwigs than the trees with more earwigs. Earwigs did suppress the woolly apple aphid.”

The damage question was a bit more complex, but also came out in the earwigs’ favour.

“We inspected apples very close to harvest when the apples were ripe,” he explained. “I looked at about 12,000 apples on the trees in the sections were earwigs had been augmented and removed. Overall, 97 per cent of the apples were good, and the chance of finding a good apple were the same in both the augmented and removal areas.”

Orpet did find stem-bowl splitting in some apples – a flaw more common in the Gala variety – and there were earwigs in some of those splits. And in a handful – 17 apples in the augmented areas and five in the removal areas – those splits appeared to have been expanded by the insects.

“My conclusion was the earwigs didn’t cause the cracking but did exploit the existing damage,” he explained.

He’s scheduled to graduate in August and has already shared the findings at growers’ meetings: clear evidence that earwigs are beneficial natural predators in apple orchards.

And, if growers are still skeptical, Orpet can always call up the video.

February 1, 2018, Madison, WI – The Colorado potato beetle is notorious for its role in starting the pesticide industry – and for its ability to resist the insecticides developed to stop it.

Managing the beetle costs tens of millions of dollars every year, but this is a welcome alternative to the billions of dollars in damage it could cause if left unchecked.

To better understand this tenacious pest, a team of scientists led by University of Wisconsin–Madison entomologist Sean Schoville sequenced the beetle’s genome, probing its genes for clues to its surprising adaptability to new environments and insecticides. The new information sheds light on how this insect jumps to new plant hosts and handles toxins, and it will help researchers explore more ways to control the beetle.

Schoville and colleagues from 33 other institutes and universities report their findings in the Jan. 31, 2018 issue of Scientific Reports.

The Colorado potato beetle’s rapid spread, hardiness, and recognizable tiger-like stripes have caught global attention since it began infesting potatoes in the 1800s. The beetle was investigated as a potential agricultural weapon by Germany in the 1940s and its postwar spread into the Soviet bloc stoked an anti-American propaganda campaign to pin the invasion on outsiders. More benignly, it has been featured on many countries’ stamps and is used in classrooms to educate about insect lifecycles.

But it was the beetle’s ability to rapidly develop resistance to insecticides and to spread to climates previously thought inhospitable that has fascinated and frustrated entomologists for decades.

“All that effort of trying to develop new insecticides is just blown out of the water by a pest like this that can just very quickly overcome it,” says Schoville. “That poses a challenge for potato growers and for the agricultural entomologists trying to manage it. And it’s just fascinating from an evolutionary perspective.”

Within the beetle’s genome, Schoville’s team found a diverse and large array of genes used for digesting plant proteins, helping the beetle thrive on its hosts. The beetle also had an expanded number of genes for sensing bitter tastes, likely because of their preference for the bitter nightshade family of plants, of which potatoes are a member.

But when it came to the pest’s infamous ability to overcome insecticides, the researchers were surprised to find that the Colorado potato beetle’s genome looked much like those of its less-hardy cousins. The team did not find new resistance-related genes to explain the insect’s tenaciousness.

“So this is what's interesting – it wasn't by diversifying their genome, adding new genes, that would explain rapid pesticide evolution,” says Schoville. “So it leaves us with a whole bunch of new questions to pursue how that works.”

Schoville and his collaborators see their research as a resource for the diverse group of scientists studying how to control the beetle as well as its life history and evolution.

“What this genome will do is enable us to ask all sorts of new questions around insects, why they’re pests and how they’ve evolved,” says Yolanda Chen, a professor at the University of Vermont and another leader of the beetle genome effort. “And that’s why we’re excited about it.”

The genome did provide a clue to the beetle’s known sensitivity to an alternative control system, known as RNA interference, or RNAi for short. The nucleic acid RNA translates the genetic instructions from DNA into proteins, and RNAi uses gene-specific strands of RNA to interfere with and degrade those messages. In the beetle, RNAi can be used to gum up its cellular machinery and act as a kind of insecticide. The Colorado potato beetle has an expanded RNAi processing pathway, meaning it could be particularly amenable to experimental RNAi control methods.

Schoville and Chen are now sequencing another 100 genomes of the Colorado potato beetle and its close relatives to continue investigating the hardiness and adaptability that have captured so many people’s attention for the past 150 years.

January 22, 2018, Edmonton, Alta – There are a number of pests that affect potatoes in Alberta every year, to varying levels of severity, depending on the year, the type and market of potatoes, as well as the location.

Alberta Agriculture and Forestry, in partnership with the Potato Growers of Alberta, has organized a series of workshops for fresh/table, seed and processing potato growers in Alberta. Participants will receive information on a number of pests (insects, diseases, weeds) and their impact, identification and management in various types of potatoes. Expert speakers have been brought in (live or pre-recorded) from across North America.

Producers may attend one of two workshops in Sherwood Park (March 6) or Lethbridge (March 8). A maximum of two attendees from each farm operation may attend. The cost to attend these workshops is $15 per person (plus GST), which includes lunch and resource materials for each farm operation.

Participants are asked to register in advance by calling the Ag-Info Centre Registration line at 1-800-387-6030 prior to February 27, 2018 to assist with planning, or register on-line.

January 4, 2018, Fredericton, NB – Chemicals in the leaves of potato plants – produced naturally by the plant – may hold the key to a new way to control Colorado potato beetles.

Dr. Helen Tai, an Agriculture and Agri-Food Canada (AAFC) research scientist, has turned to the leaves growing on wild potato relatives, leaves that beetles won’t eat, as a new approach to keep the pest away.

Many plants in the potato family contain natural defence chemicals that protect plants against insects and pathogens. Using mass spectrometry and other sophisticated tools, Dr. Tai was able to identify what it is in the wild potato plant leaves that make the beetle avoid them.

Potato breeders at the Fredericton Research and Development Centre used cross breeding of a wild relative with common popular potato varieties to develop a potato with built in beetle resistance. Not all of the potatoes from the cross carry the resistance, but the profile that Dr. Tai discovered identifies which ones do.

“Breeding new potato varieties resistant to beetle feeding, now in the advanced stages, opens the way to a new era where potato growers could reduce pesticide spray applications for insect control,” said Dr. Tai.

Colorado potato beetles are already showing a resistance to the popular pesticides used by potato growers adding to the need for new solutions. Dr. Tai sees use of beetle resistant varieties together with integrated pest management methods as an alternative approach to mitigate pesticide resistance. These resistant potato varieties can provide growers with an option to avoid serious crop losses.

Two of these new resistant potatoes are already in the breeding program and available to industry to trial.

December 8, 2017, Ithaca, NY – The New York State Department of Agriculture and Markets recently confirmed that the spotted lanternfly – an invasive insect originating in East Asia – has been found in New York state.

This invasive pest has also been discovered in Pennsylvania and other states, and is a potential threat to important agricultural crops, including grapes, apples, hops and forest products.

According to the Canadian Food Inspection Agency (CFIA), the pest is not known to occur in Canada and is not yet on Canada's list of regulated pests. However, it may appear in Canada. Any producers who believe they have found suspect specimens are urged to please contact the CFIA.

Tim Weigle, statewide grape and hops integrated pest management specialist with the New York State Integrated Pest Management Program, works with grape and hop growers in implementing research-based IPM practices in environmentally and economically sustainable ways. He says the spotted lanternfly could rapidly expand its range by laying eggs on motor vehicles.

“The name spotted lanternfly is a bit misleading as this plant hopper grows to one-inch in size as an adult,” he said. “Large groups of both the immature and adult stages of laternfly feed on plant stems and leaves from early spring to September, weakening and possibly killing the plant. They also excrete a sugary, sticky substance similar to honeydew, which leads to the growth of sooty mold on grapes, apples and hops making them unmarketable.

“I would be concerned about any shipments that people are getting that originated in the Pennsylvania counties that are currently under quarantine. While this pest seems to prefer tree of heaven, it appears to be able to lay its eggs on any smooth surface like cars, trucks, tractors or stone. Therefore, the major traffic corridors coming up into the Hudson Valley and Finger Lakes area will probably have a greater potential for spotted lanternfly eggs being transported in due to vehicle traffic.”

Elizabeth Lamb, coordinator for the ornamental integrated pest management team for the New York State Integrated Pest Management Program says that grape, hop and ornamental growers, along with tree-fruit producers, are most likely to be impacted by this invasive pest.

“The industries most likely to be affected by spotted lanternfly in New York state are grapes and hops, tree-fruit production, and ornamentals,” she said. “Once you consider the ornamental hosts, it becomes an issue for homeowners and landscapers, too. So the first and most important piece in controlling spotted lantern fly is observation and monitoring – by growers and the public.

“A small bright spot: the biology of the insect provides several avenues for using different methods of control. Egg masses can be scraped off the smooth surfaces where they are laid and then destroyed. Nymphs crawl up and down tree trunks to feed so they can be caught on sticky traps at the right time. Adults have a preference or requirement for feeding on Ailanthus trees (Tree of Heaven), so the Ailanthus can be used as ‘trap’ trees where pesticides are applied very specifically to control the insect without widespread use.”

August 16, 2017, Lethbridge, Alta. - Alberta’s potato industry is worth more than $1 billion to our economy. But it’s threatened by a tiny bacterium

This year, a Lethbridge scientist reports, it hasn’t shown up.

“That’s good news,” says Dan Johnson, a biogeography professor at the University of Lethbridge. He explains the bacteria are linked with zebra chip disease – already affecting crops in the U.S., Mexico and New Zealand. It turned up as early as May in Idaho this year.

Potatoes infected by the bacteria develop unsightly black lines when they’re fried, making them unfit for sale. The bacteria are carried by an insect, the potato psyllid. READ MORE

August 11, 2017, Toronto, Ont – Vive Crop Protection recently announced a new partnership with four biopesticide manufacturers to develop new and improved biopesticides, supported by Sustainable Development Technology Canada (SDTC).

Biopesticides are the fastest growing crop protection segment, but have suffered from limited effectiveness in field situations, shorter product life, poor compatibility with conventional pesticides, and limited combination products. Vive has recently demonstrated that the Allosperse Delivery System enhances the viability and performance of biopesticides.

“This project extends the scope of the Allosperse Delivery System and means that we can provide a complete solution to growers, whether they need a conventional, biological, or combination crop protection product,” said Keith Thomas, CEO of Vive. “We’re excited about the potential for these products and thank SDTC for the support.”

Over the next three years, Vive will work with the partner manufacturers to develop new and improved versions of their products. This work will be supported by SDTC.

Vive Crop Protection is developing environmentally-friendly pesticides made from organic matter,” said Leah Lawrence, president and CEO of Sustainable Development Technology Canada. “This Canadian-made technology represents an advancement in biopesticides that will deliver real economic and environmental benefits across Canada and around the world.”

July 17, 2017 - Entomopathogenic nematodes are soft bodied, non-segmented roundworms that are obligate or sometimes facultative parasites of insects.

Entomopathogenic nematodes occur naturally in soil environments and locate their host in response to carbon dioxide, vibration and other chemical cues. Species in two families (Heterorhabditidae and Steinernematidae) have been effectively used as biological insecticides in pest management programs.

Entomopathogenic nematodes fit nicely into integrated pest management or IPM programs because they are considered non-toxic to humans, relatively specific to their target pests, and can be applied with standard pesticide equipment.

This video will provide a breif overview of how to check the viability of nematodes and how to apply them.

June 16, 2017, Saint John, NB – A honey bee pest, the small hive beetle, Aethina tumida, has been reported in New Brunswick for the first time.

It has been found in honey bee colonies imported from Ontario in wild blueberry fields at the following locations:
  • Alnwick (near Brantville)
  • Pont-Lafrance in Gloucester County
  • two locations near Saint-Sauveur (Lord and Foy area)
  • Saint-Isidore
All imported colonies and NB colonies in blueberry fields from the areas indicated above are in quarantine until further notice. They are not permitted to be moved within blueberry fields or between blueberry fields.

In order to locate NB bee colonies in these areas, DAAF would like NB blueberry growers with fields in these areas to contact department staff and indicate where the NB colonies are located and who they belong to.

May 26, 2017, Ontario - The U.S. Animal and Plant Health Inspection Service is banning imports of fresh cherries from Ontario, following “multiple detections” of the European cherry fruit fly.

The May 23 U.S. Department of Agriculture-APHIS order applies to commercial and non-commercial imports.

Black, mahaleb, sour and sweet cherries are included in the ban. Wild honeysuckle, the fly’s other host plant, also is banned.

Restrictions for Ontario cherries will be in effect until the pest is eradicated from the province, APHIS legislative public affairs specialist Yindra Dixon said.

The pest has not been found in the U.S., but it could establish populations in northern regions of the U.S., Dixon said.

“The climatic tolerance and available hosts of this fruit fly would allow (it) to establish in the United States if introduced from Canada,” Dixon said. “This fruit fly is a serious economic pest of commercial cherries in Europe, where imports of cherries are also restricted.”

On Feb. 4, 2016, USDA identified a fruit fly photographed in Mississauga, Ontario, as likely a European cherry fruit fly. The Canadian Food Inspection Agency (CFIA) began surveys for the pest in Ontario in April 2016. In June 2016, one of the flies was found on honeysuckle in southeastern Ontario. READ MORE

May 23, 2017, New Brunswick - Agriculture and Agri-Food Canada entomologist Dr. Chandra Moffat is on the lookout for evidence of an agricultural pest that is causing significant damage to crops in the U.S. and parts of Canada.

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.

May 9, 2017, Columbus, OH – When Celeste Welty unzips the white, nylon cage, none of the stink bugs inside move.

“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.

April 21, 2017, Morgantown, WV - Gallegly, West Virginia University professor emeritus of plant pathology, has made it his mission to develop a disease-free tomato.

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

For fruit growers across the globe, birds are a common bane, particularly for those seeking a quiet, humane and cost-effective mitigation strategy. Starlings are especially unsavory interlopers as they not only spread disease but often destroy an entire crop, forcing growers to walk away and leave everything on the tree.
