Abstract
The objective of the present investigation was to evaluate rearing of Coccinella undecimpunctata L. on an artificial diet and Ephestia kuhniella eggs. Significant differences were observed between the artificial diet and E. kuhniella eggs on the incubation period and the total immature stages duration at the three tested temperatures. The life cycle of C. undecimpunctata was the shortest when reared on the artificial diet and E. kuhniella eggs at 30 ± 1ºc and 65 ± 5% R.H. and lasted 27.5 ±0.15 and 22.7 ± 0.20 days, respectively. The total larval survival rate was the highest for C. undecimpunctata when reared on E. kuhniella and recorded 86.67 %, 96.67% and 90% at the three different temperatures. The longest female and male longevity were observed when reared at 20 ± 1 oC on two diets. The high fecundity value was found at 25± 1 oC for two diets followed by 30 ± 1 oC. While, it was lowest at 20 ± 1 oC for C. undecimpunctata.
