Integrated pest management approach for a new pest, Lacanobia subjuncta (Lepidoptera: Noctuidae), in Washington apple orchards
Pest Management Science 60 (10), 1025-1034
Abstract: Bioassays of Lacanobia subjuncta (Grote and Robinson) larvae established baseline LC50 values and identified the potential of reduced-risk, organophosphate replacement and naturally derived insecticides (eg chloronicotinyls, spinosyns, oxadiazines, insect growth regulators, microbial insecticides and particle films) to control this pest. The toxicities of these products were compared with those of organophosphate, carbamate, chlorinated cyclodiene and synthetic pyrethroid insecticides used in the management of lepidopteran pests in Washington apple orchards. Field trials were conducted comparing candidate insecticides to conventional alternatives. Several new insecticides (eg spinosad, methoxyfenozide, indoxacarb and an aluminosilicate particle film) proved to be effective for the management of L. subjuncta. We summarize the goals and challenges of developing an integrated pest management program for new and resurgent pests as insecticide tools continue to change, and propose a hypothesis for the sudden increase in pest status of L. subjuncta based on organophosphate tolerances. The role of novel insecticides with unique modes of action in resistance management and the encouragement of biological control are also discussed.
