Overwintered larvae and pupae complete development in the spring and emerge as adults beginning in late May or early June. Eggs usually hatch within 10 days and larvae burrow down to feed on roots until activity is stopped by cold weather. Adult feeding is insignificant and is restricted to eating notches out of leaves. Larval root and crown feeding result in weakened, stunted, or dead plants, particularly if the crown is girdled. Cultural controls are as those listed for strawberry crown borer.
Adults can also become a nuisance when they move into homes in late summer and early fall.
Recommendations listed in NebGuide G77-342, Sowbugs and Pillbugs , for controlling migrations of sowbugs and pillbugs should suffice for root weevils. As a result, most problems with these insects in strawberries occur the first few years out of sod. Wireworm adults are elongate, slender, hard-shelled beetles that take their name from their habit of flipping into the air with a noticeable clicking sound when they are placed on their backs. Eggs are deposited in the soil and hatch in a few days to a few weeks. Larvae feed on the roots and crowns of various plants.
