March 14, 2016, Prince Edward Island – Agriculture and Agri-Food Canada entomologist Dr. Christine Noronha has designed a simple and environmentally green trap using hardware store items that could be a major breakthrough in the control of wireworms, an increasingly destructive agricultural pest on PEI and across Canada./span>
The Noronha Elaterid Light Trap, or “NELT”, is made with three pieces – a small solar-powered spotlight, a plastic white cup and a piece of screening. The light is set close to the ground to attract the source of the wireworms, the female click beetles that emerge from the ground in May and June. Each of these beetles can lay between 100 and 200 eggs that produce the larvae known as wireworms. In a six-week test with 10 traps, more than 3,000 females were captured in the plastic cups, preventing the birth of up to 600,000 wireworms. The screening prevents beneficial predator insects from being caught in the trap.
Agriculture and Agri-Food Canada’s Office of Intellectual Property is trademarking the trap name and design and work is underway to find a manufacturer who might be interested in mass-producing the trap.
The NELT is the latest in a series of wireworm control measures being developed by a team that includes Agriculture and Agri-Food Canada, the PEI Potato Board, the PEI Department of Agriculture and Fisheries, the Pest Management Regulatory Agency, Cavendish Farms, the PEI Horticultural Association, growers and consulting agronomists. Wireworms live in the soil and drill their way through tuber and root crops like potatoes and carrots. The PEI Potato Board estimated wireworm damage to the province’s potato crop alone at $6 million in 2014.
