Abstract

Pachylobius picivorus (Germar) is one of the weevils which is assuming increased importance as a pest of natural and planted pine seedlings. Brood development requires from 100 to 128 days during the summer. Weevils are long lived, with oviposition occurring at a rate of approximately 0.7 eggs per day per female for the life of the insect. There are two population peaks during the year in the Georgia Piedmont. These peaks reflect the response of the weevils to temperature and to developmental cycles.
