Adult plum gouger weevils have smooth dark brown wing covers and yellow-brown heads and legs. They are similar to the plum curculio, but plum curculios are rarely observed.
The eggs are laid under the skin of the fruit, and the larvae burrow in to feed on the stone.
Primarily attacks native plums, although adults may feed on buds and blossoms of peaches and plums. Damaged fruit becomes gnarled and distorted from adult feeding and egg-laying punctures, and the larvae feed on the kernels of the pits.
Clear fallen leaves and dropped fruits from under fruit trees on a regular basis to reduce hiding places for adult curculios and to keep larvae from reaching the soil to pupate. Adult curculios can be killed with insecticide. Spraying is most effective if done right after petal drop, the time when adult curculios are actively crawling on branches and beginning to lay eggs. Once the eggs and larvae are in the fruit, no amount of spraying will deter them.
