Longevity and Life Table of the Foxglove Aphid (Aulacorthum solani K.) Adults on Lettuce (Lactuca sativa L.)
Abstract
Adult longevity and fecundity of the foxglove aphid, Aulacorthum solani Kaltenbach, were studied at 12.5~25℃ with 60~70% 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℃. Also total fecundity increased with decreasing temperature and highest fecundity was 74.1 nymphs per female at 15℃. However, daily fecundity increased with increasing temperatures up to 20℃ showing 2.9 nymphs per day and thereafter decreased. Net reproduction rate (R₀) was highest of 58.7 at 15℃. The intrinsic rate of increase per day (rm) and the finite rate of increase per day (λ) 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℃.
