Weevils

Description:
Plum curculio weevils are 1/4 inch long, gray to black. Larvae develop inside fruit and appear as white legless grubs with brown heads, up to 3/8 inch long. The plum gouger attacks plums, although adults also feed on buds and blossoms of peaches and plums. Adult plum gouger weevils have smooth, dark brown wing covers and yellow-brown heads and legs. Adult pecan weevils are 3/8 inch long brownish beetles with snouts as long as the body. Grubs are legless, creamy white and have reddish-brown heads and grow up to 3/5 inch long. Several species of acorn weevils occur. Acorn weevil adults and larvae are similar in appearance to pecan weevils. Larvae and pupae become common in flowerbeds in which acorns have fallen.

Damage:
Female fruit feeding weevils cause egg-laying scars on developing peaches, plums, pears, apples, mayhaws, and some small berries; infested fruit drops from trees. Adult pecan weevils feed and oviposit eggs on developing pecan nuts, causing them to drop. Larval stages mature in more developed nuts, destroying the kernels.
