Potato tuberworm moths have been captured in pheromone traps in Malheur Co (Stuart Reitz, Malheur Co. Cooperative Extension). Feeding by tuberworm larvae may cause extensive damage to tubers in the field and in storage. Thus far, we are unaware of current tuberworm infestations in Idaho; however, Mike Cooper, ISDA, in cooperation with Bill Buhrig, Jim Barbour, and Erik Wenninger, University of Idaho, will be deploying some pheromone traps in Idaho to monitor for moths. We encourage growers and crop consultants, especially those in western Idaho, to be aware of this pest.
