Adult development and fecundity of the green peach aphid, Myzus persicae Sulzer, were studied at 15~32.5℃ with 60~70% RH under 16L:8D and the results were put together to build a life table. The longevity shortened as temperatures rose at and below 25℃ whereas it remained relatively constant at 27.5℃. Total fecundity was not significantly different at all temperatures except at 30℃. Daily fecundity gradually increased from 15 to 22.5℃. It was 5.1 at 25℃ and as temperatures either went down or up, it decreased to 2.8 at both 15℃ and 30℃.
