Anthonomus quadrigibbus (Say)

Life Cycle: Overwinter as adults under the host; eggs are laid May to late June. Larvae are present June to mid-July. New adult generation active mid-July to mid-August before overwintering. One generation per year.

Monitoring: No monitoring plan developed. Limb taps around petal fall of pear are useful to detect adults. Inspect young fruit for feeding and/or egg-laying punctures.

Hosts: Apple, pear, crabapple, hawthorn, quince, cherry.

Comments: The reddish-brown adult weevils are slow-moving and will drop readily and play dead when disturbed. They could be mistaken for a piece of debris on a beating board until they resume activity.
