Some Laboratory Investigations of the Light Reactions of the Larvae of Neodiprion americanus banksianae Roh. and N. lecontei (Fitch) (Hymenoptera: Diprionidae)

Abstract

This paper deals with two sawfly species, Neodiprion americanus banksianae Roh. and N. lecontei (Fitch), important defoliators of pines in eastern North America. It is concerned chiefly with the reactions of the larvae to light and forms part of an investigation of their behaviour in response to physical factors of the environment.
