The Codling moth is frequently referred to as “apple worm” or “maggot.” Coddling moths are very common pests that make their homes in apple, pear and other fruit orchards worldwide. Females lay eggs on the leaves of fruit trees and the resultant larvae burrow into fruit immediately after they hatch. Generally, the larva will remain in the fruit and feed on it for about 3 weeks until it is ready to find a new home where it will overwinter and pupate.
Codling moths can, and often do, wipe out entire crops of fruit if they are left untreated. There are several options to prevent infestations. Most commonly, growers elect spray methods. Although there are several applications necessary to properly control the codling moth, it has proven to be the best solution for worm free fruit. Applications generally begin in the first week of May and continue every 3-4 weeks until harvest to ensure control.
The biggest challenge can be timing the spray applications. It’s important to calculate the degree-days to approximate when the moth will be most vulnerable. “Degree-days” refer to daily change in temperature. Understanding and monitoring these changes allows us to determine when applications will be the most effective in treating fruit trees.
