Abstract

The mean duration of development of Cheilomenes sexmaculata (Fabricius) reared on Melanaphis indosacchari David was 11.3±2.4 days. The adults survived for 22.7±9.1 days when fed with aphids. The feeding potential of grubs was 220.2±17.4 aphids in the case of M. indosacchari and 179.6±40.5 aphids in Melanaphis sacchari Zehnt. The adult beetles preyed a mean of 992.8±256.8 M. indosacchari and 1403.3±99.9 M. sacchari, respectively. The feeding potential of grubs increased with age while that of adults decreased with age.
