| 中文摘要: |
| 组建了菜粉蝶(Pieris rapae L.)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49.52 d，而28 ℃时仅为20.38 d。成虫寿命随温度升高而逐渐缩短，16 ℃时最长为8.62 d，在28 ℃下最短为3.01 d；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。 |

| Life table of the laboratory populations of Pieris rapae L. were constructed at five different temperatures (16 ℃, 19 ℃, 22 ℃, 25 ℃ and 28 ℃). 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. |
