Abstract

The average biology of Coccinella undecimpunctata L. were showed that when it was reared on Sitobion avenaeFab.The incubation period, total larval stage period , pre-pupal period, pupal and adult male and female periods was 7.0 ± 0.0, 13.4 ±0.7, 1.4±0.5, 6.6 ± 0.5, 63.7 ± 23.7 and 78.7 ± 9.3 days, respectively, whereas on Schizaphis graminum Rond., these periods were 7.0 ± 0.0, 14.8 ± 0.7, 1.4±0.5, 60.± 0.7 and 61.0± 8.0 and 82.3 ± 11.7 days, respectively. The mean fecundity of C. undecimpunctata on S. avenae and S. graminum were 415 ± 154.7 and 406.7 ± 51.7 eggs per female, respectively. Total longevity of male and female C. undecimpunctata on S. avenae and S. graminum were 92.1 ± 24.6 and 90.2 ± 8.4 and 107.1 ± 10.2 and 111.5 ± 12.2 days, respectively.
