Interpretive Summary: A serious problem to apple growers is reintroduction of codling moth to orchards by returning fruit bins containing overwintering larvae. Researchers at the USDA-ARS Yakima Agricultural Research Laboratory in Wapato, Washington, examined hot water baths as a method of control. Working with a local packing house, they demonstrated that submerging bins in an 80°C water bath would significantly reduce the larval population. This procedure, when adopted by other commercial facilities, will be an important component in the field control of codling moth.

Technical Abstract: 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°C for > 30 sec were effective and adding a surfactant to the water bath slightly improved efficacy. A validation tests conducted at a packing house, using a 80°C submersion bath for bins, resulted in < 0.2% survival. This procedure should be an important component for field control of codling moth.
