Abstract
Little has been published concerning the influence of moisture on development of the redheaded pine sawfly [Neodiprion leconfei (Fitch)] . The effects of relative humidity (RH) on development within the cocoon and adult emergence have not been systematically investigated. Brown and Daviault (1942) noted greater survival by cocoons subjected to 4045% RH than others at 90-9576. Deneve (1968) concluded that RH had little effect on emergence of adults. His study was made with small unreplicated samples and should probably be regarded as inconclusive. The purpose of this laboratory study was to determine whether constant humidity, at various levels, affects emergence from cocoons by male lecontei adults.
