The Black Vine Weevil (Prachyrhinus Sulcatus Fabr.) As a Pest In Greenhouses and Nurseries

Abstract

This paper is presented as a progress report on the studies of Brachyrhinus sulcatus Fabr. in the nurseries and greenhouses of Pennsylvania. Its distribution in Pennsylvania, the possibility of its being distributed by means of Taxus as balled nursery stock, and the relationship between greenhouse infestations and Taxus are discussed. Life history studies thus far indicate that greenhouse plants are infested by adults developing out of doors. The species is capable of parthenogenetic reproduction. Dry lead arsenate mixed with the potting soil gives promise of one method of control for this insect on greenhouse plants.
