Codling moth apple damage becoming more prevalent
Extension experts say codling moth larvae are tunneling into apples, with up to 75% of fruit affected and control timing critical.
- About 75% of apples in North Dakota and Minnesota are showing classic symptoms of codling moth larvae damage, with larvae chewing openings into the apple skin.
- Adult moths lay eggs on developing fruits as flower petals drop, and each female moth can lay up to 100 eggs that hatch into larvae tunneling toward apple cores.
- Although it is too late to control codling moths now, gardeners can mark calendars for next year; insecticidal control using Spinosad must begin as soon as flower petals drop.
- Three repeat applications at 10-day intervals are recommended to avoid insects developing resistance, while pollinating bees are no longer visiting the trees at that time.
- Don Kinzler of NDSU Extension-Cass County provides professional advice on managing future orchard damage; gardeners with questions regarding insect control can email him for guidance.
