Suppression of Colorado Potato Beetle, Leptinotarsa decemlineata (Say), (Coleoptera: Chrysomelidae) Populations with Antifeedant Fungicides
Laboratory, small-field plot, and commercial-scale experiments were completed, using Connecticut, Rhode Island, and New York Colorado potato beetle, (CPB) Leptinotarsa decemlineata (Say), populations to determine if "antifeedant fungicides" might reduce the suitability of potato for CPB while simultaneously protecting potato from early and late blight. In the laboratory. fungicides formulated f...
متن کاملVoltinism and the Induction of Aestival Diapause in the Colorado Potato Beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
Field studies over 3 yr demonstrated that overwintering populations of the Colorado potato beetle in upstate New York and on Long Island are composed of adults from both the first and second summer generations. The two populations from the climatically different regions differ in their responses to environmental factors that influence voltinism. The critical photoperiod for aestival diapause in...
