A laboratory experiment was conducted in the Bio-Control Research laboratory, Department of Entomology, Faculty of Crop Protection, Sindh Agriculture University, Tandojam in 2016. The egg laying capacity (Fecundity) of the female Coccinella septempunctata showed that the maximum fecundity was recorded 1241.24±10.25 on mustard aphid, whereas the lowest pre-oviposition period was recorded in female fed on cabbage and mustard aphids. The maximum ovipostion period was observed on cabbage aphid followed by mustard and akk aphids, respectively. The lowest larval cannibalism% was seen 14.0±5.77 on mustard aphid while the highest larval mortality% 20.0±83.0 and 23.0±10 on cabbage and akk aphids. The maximum adult emergence% of Coccinella septempunctata on mustard aphid followed by cabbage and akk aphids, respectively. The results of the present research showed that the minimum development period was observed in the 1st, 2nd, 3rd and 4th instar larvae fed with mustard aphid, Lipaphis erysimi followed by Cabbage aphid, Brevcoryne brassicae and Akk aphid, Aphis nerii, respectively. The highest adult male longevity of Coccinella septempunctata was seen 69.68±11.25 days on cabbage aphid whereas maximum female longevity was recorded 85.0±8.41 and 91.23±10.81 days of akk and cabbage aphids, respectively. The result further revealed that the adult male and female was lived longer on cabbage aphids There is highly significant difference in the longevity of male and female of different host species (P<0.05).
