Abstract:
Studies on biology of reduviid bug, Rhynocoris marginatus reared on rice moth, Corcyra cephalonica were carried out at Entomology Laboratory, College of Horticulture, Mojerla. Experimental results revealed instar wise nymphal durations of 6.2±0.60, 7.4±0.49, 9.2±0.80, 12.1±1.20 and 22.3±1.40 days for I, II, III, IV and V instar, respectively, whereas, the adult male and female longevity was 91.20±4.45 and 118.4±6.40 days, respectively. The incubation period of eggs was 10.2±0.75days, fecundity and hatching percentage was 350±10.20 eggs per female and 85.50±5.20 percentage, respectively. Oviposition period was 50.4±4.47. The total developmental period for predatory bug, R. marginatus reared on rice moth, C. cephalonica was shorter with higher fecundity due to ideal period for rearing under ambient conditions.
