Effect of Different Diets on The Development and Morphometric of Coccinella septempunctata (Linneous)

A laboratory experiment was carried out to determine the effect of different diets on biology of Coccinella septemputata Linneous, in the | department of Plant protection, Sindh Agriculture University, Tando Jam, Pakistanduring 2011 and 2012 at 28±2 ºC and 65±5% relative humidity. The result showed that total larval developmental period was recorded 8.0 ± 0.72 and 7.8 ± 0.69 days on grain moth eggs and safflower aphid, respectively, however, no significant difference was recorded between pre-pupal and pupal period on grain moth egg and safflower aphid. The adult longevity of male (43.10 ± 1.04 and 56.50 ± 1.61) and female (36.07 ± 0.24 and 42.50 ± 0.69 days) was significantly different on grain moth eggs and safflower aphid, respectively. The larval instars were not survived on prepared artificial diet, however, only adult male and female survived (68.50 ± 2.03 and 72.90 ± 2.07 days) without fecundity. The result further revealed that the length and breadth (mm) of larval instars, pupa and adults of C. septempuntata was significantly varied feeding on grain moth eggs and safflower aphid
