Results revealed that aphids were slightly more preferred (53.8%) as compared to mealy bugs (46.2%) when both were exposed together to adult of Coccinella septumpunctata in free choice test. In no choice test, when aphids and mealy bugs were fed individually to Coccinella septumpuctata, the predation of mealy bugs was 80 per cent after 24 hours; however it increased to 84.7 per cent after 96 hours. The overall mealy bugs consumption varied from 24.0 ± 0.77 to 25.40 ± 0.98 per day. The mean number of aphids consumed the predator varied from 26.00 ± 0.81 to 28.00 ± 0.71 per day and the per cent predation was 88.7 per cent after 24 hours and it increased to 93.3 per cent after 96 hours.
