FORT KENT, Maine - This European corn borer trap was photographed on June 14, alongside some potato fields on the Fort Kent / Frenchville town line. It is one of 20 throughout the St. John Valley, according to Jim Dwyer, with the University of Maine Cooperative Extension’s Potato Integrated Pest Management Program. The insects can cause problems for potato crops in northern Maine, although they are not a problem in southern parts of the state, he said. The trap uses a pheromone to attract male moths, which are then collected and counted. Along with these net traps, Dwyer said his program also collects aphids with yellow water pans, and uses vacuum insect traps placed atop 26-foot poles, and black light traps.
