Choristoneura rosaceana (Harris) and Pandemis pyrusana Kearfott (Lepidoptera: Tortricidae) male control in Washington State (USA) apple orchards treated with different source densities of several attracticide formulations

摘要

Attracticides have been reported for several Tortricidae. Formulations include the specific sex pheromone to attract male moths and an insecticide to kill them after contact. Attracticides are an alternative to conventional pesticides, and reduce risks for applicators, the environment, and beneficial arthropods. The objective of this study was to evaluate attracticides containing either 1.6 or 16% of the pheromone, with or without permethrin, using different source densities, to suppress male populations of C. rosaceana or P. pyrusana, two increasingly important apple pests in the State of Washington, USA, under field conditions.
