中国人. 摘 要：组建了菜粉蝶（PierisrapaeL．）在16、19、22、25℃和28℃下的实验种群生命表。结果表明：各虫态的发育速率随温度的升高而变快，且在16-28℃内，菜粉蝶的各虫态均能正常发育。在16℃下世代的发育历期最长为49．52d，而28℃时仅为20．38d。成虫寿命随温度升高而逐渐缩短，16℃时最长为8．62d，在28℃下最短为3．01d；单雌产卵量在25℃时最高，平均为120．13粒，16℃和28℃最低，平均为110．01粒。在恒温22-28℃内，种群趋势指数较高，这说明在该温区较适合于菜粉蝶的生长发育。

The results showed that this insect could normally develop between 16 ℃ and 28 ℃. Their developmental rate increased with increasing temperature. The longest immature duration was 49.52 d at 16 ℃, and the shortest was 20.38 d at 28 ℃. The longest adult longevity was 8.62 d at 16 ℃, while the shortest was 3.01 d at 28 ℃. The maximum fecundity was 120.13 per female at 25 ℃, while the least was 110.01 at 16 ℃ and 28 ℃. The suitable temperature range for this insect was 22--28 ℃, at which it had higher population increase index.
