Bin Sterilization to Prevent Reintroduction of Codling Moth

摘要

An important source of reinfestation of codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), is the return of fruit bins containing diapausing larvae. Laboratory tests, conducted to determine efficacious temperatures of hot water baths to prevent adult emergence, found baths at 80 deg C for >30 sec were effective and adding a surfactant to the water bath slightly improved efficacy. Validation tests conducted at a packing house, using an 80 deg C submersion bath for bins, resulted in < 0.2% survival. This procedure should be an important component for field control of codling moth.
