Thus in the present study the suitability of ten aphid species of a ladybird beetle <i>Anegleis cardoni</i> (Weise) in terms of growth, development, survival and mortality life table attributes was assessed for the purpose of mass production. The study revealed that the developmental duration of the immature stages of <i>A. cardoni</i> was shortest when fed on <i>Uroleucon compositae</i> (Theobald), <i>Rhopalosiphum maidis</i> (Fitch), <i>Hyadaphis coriandri</i> (Das) and <i>Myzus persicae</i> (Sulzer) in comparison with other aphid species. Immature survival, development rate, adult weight and growth index were also highest when <i>A. cardoni</i> larvae were fed on these aphids, while lowest when fed on <i>Hysteroneura setariae</i> (Thomas) and <i>Ceratovacuna silvestri</i> (Takahashi). Any larva of <i>A. cardoni</i> did not reach adult stage when fed on <i>Aphis nerii</i> Boyer de Fonscolombe; therefore it may be considered as a toxic prey. Life table data revealed that the overall mortality prior to adult stage was lowest in <i>U. compositae</i> and highest in <i>C. silvestri</i>. The first instars suffered the highest mortality in comparison with other instars on all the aphid species tested. However, the life expectancy for each aphid species as prey revealed a continuous decline with the advancement of age. Thus among all the ten aphid species tested, <i>U. compositae</i>, <i>R. maidis</i>, <i>H. coriandri</i> and <i>M. persicae</i> were found equally suitable for mass production of <i>A. cardoni</i>. 收起
