Abstract
Adult longevity and fecundity of the foxglove aphid, Aulacorthum solani Kaltenbach, were studied at $12.5{\sim}25^{\circ}C$ with $60{\sim}70%$ RH under 16L:8D and the results were put together to build a life table. The longevity of foxglove gradually increased with decreasing temperature below $25^{\circ}C$. Also total fecundity increased with decreasing temperature and highest fecundity was 74.1 nymphs per female at $15^{\circ}C$. However, daily fecundity increased with increasing temperatures up to $20^{\circ}C$ showing 2.9 nymphs per day and thereafter decreased. Net reproduction rate ($R_0$) was highest of 58.7 at $15^{\circ}C$. The intrinsic rate of increase per day ($r_m$) and the finite rate of increase per day (${\lambda}$) were highest of 0.27 and 1.32, respectively and the doubling time (Dt) was shortest of 2.52. the mean generation time (T) was 10.99 at $22.5^{\circ}C$.
