Biology of a Predaceous Stinkbug, Stiretrus Anchorago, (Hemiptera: Pentatomidae)
Abstract
Stiretrus anchorago (F.) was collected from S. C. soybean fields and reared at 3 constant temperatures. Larvae of 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 32.2@*C, respectively. Mean numbers of eggs per female were 12.6, 57.3, and 15.0 at 18.3, 26.7, and 32.2@*C, respectively. The immature stages (eggs and instars) completed development in 42.8, 24.6, and 22.6 days at 18.3, 26.7, and 32.2@*C, 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 Galleria mellonella (L.) larvae exclusively.Downloads
