Abstract

Cocoons of Peristenus stenodemae Loan, a nymphal parasitoid of Stenodema virens (L.), were exposed to varying degrees of cold during diapause and tested for survival and emergence time. Survival of pupae was highest at temperatures above zero. Mortality increased with decreasing temperature reaching 100% at bout -20°C. Three to four weeks were needed to reach 50% emergence after cold storage.
