Abstract	An experiment was conducted to determine the feedin g potential of lady bird beetle, Brumus suturalis (Fab.) on cotton Mealy bug, Phenacoccus solenopsis in the laboratory and field conditions in Departmen t of Entomology, Sindh Agricultural University, Tandojam , Pakistan during July – August, 2007. The laborato y results revealed that B. suturalis was voracious fe eder of Mealy bugs. The fourth instar devoured max i um mean number of Mealy bugs (55.11±1.38) /day/larva f ollowed by third instar (32.51±1.09), second instar (32.5±0.08) and first instar (25.1±1.41) Mealy bug and the adults female devoured more number of Mealy bug (131.51±2.10) than male (129.57±314) per day under laboratory conditions (26+2C). The field results showed that, fourth instar devoured more mean number of Me aly bugs / day / larva of (34.6±1.41), followed by third instar (25.0±0.63), second instar (23.7±0.47) and f irst instar (19.0±0.16) Mealy bug/larva/day) and th e adults female devoured more mean number (72.03 ± 6.16) than male (69.9 ± 6.31) per day. The lower consumption rate in the field may be attributed to the additional ti me required by the predators in searching of prey.
