Studies on Biology of Amphibolus venator (klug) on Corcyra cephalonica Stainton

The biology of Amphibolus venator was studied on Corcyra cephalonica under laboratory conditions. The egg period was 16.33±1.24 days, with the range of 15-18 days. There were five nymphal instars in Amphibolus venator . The nymphal period for I, II, II, IV and V instar lasted for 23.33±3.14, 30.83±6.06, 38.33±9.70, 40.16±3.67 and 40.00±4.63 days, respectively. The total developmental period was 172.65±15.50 days. The longevity of female was 65.83±2.4 days with range of 63 to 68 days and male was 59.33±2.49 with range of 57 to 62 days; the fecundity per female was 210 with range of 200 to 220 eggs.
