Abstract

Stiretrus anchorago (F.) was collected from S.C. soybean fields and reared at 3 constant temperatures. Larvae of [Mexican Bean Beetle] Epilachna varivestis Mulsant were used as prey for S. anchorago in life history studies.
Female adults lived an average of 46.0 29.6, and 12.6 days; males 38.2, 24.8, and 22.4 days at constant temperatures of 18.3, 26.7, and 32.2dC, respectively. Mean numbers of eggs per female were 12.6, 57.3, and 15.0 at 18.3, 26.7, and 32.2dC, respectively.
The immature stages (eggs and instars) completed development in 42.8, 24.6, and 22.6 days at 18.3, 26.7, and 32.2dC, respectively.
Eggs laid by field collected females and held at 26.7@*C were more viable (88.5%) than eggs from laboratory reared females (19.0%). Only infertile eggs were produced by females fed [Greater Wax Moth] Galleria mellonella (L.) larvae exclusively.
