Journal of Plant Protection Research 51 (2), 190-194
Abstract: Hippodamia variegata (Goeze) is a natural enemy of the bean aphid. In this study, the duration of hatching, larval instars and pupal stages of H. variegata feedingon black bean aphid, Aphis fabae Scopoli were investigated under laboratory conditions (25±1°C, 60±5% relative humidity and 16:8 (light:darkness) hours photo period. The mean pre-oviposition period of H. variegata was 6.20±0.13 days and the oviposition period was 43±0.21 days.The female beetles laid on an average 943.90±53.53 eggs and the hatching % was 82.86±3.12. The average incubation period was 3.35±0.11 days and the duration of total larval period from egg to adult was 16.5±0.13 days. The pre-pupal and pupal periods were 1.40±0.16 and 3.10±0.07 days, respectively. The mean longevity of the male and the female beetles were 50±3.2 and 55.5±3.37 days, respectively.
