ABSTRACT
Hippodamia variegata
(Goeze) is a among natural enemy of bean aphid so far identified in the world. In this study, the duration of hatching, larval instars and pupal stages of
H. variegata
feeding on black bean aphid,
Aphis fabae
Scopoli were investigated
under laboratory conditions (25±1°C, 60±5% relative humidity and 16:8 (light:darkness) hours photoperiod. 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.
