中文摘要：
完成多异瓢虫Hippodamia variegata (Goeze)在13，17，21，25，29和33℃ 6个温度处理下的繁殖特征生命表。结果表明：各虫态的发育速率随温度的升高而加快，在13℃下世代的发育历期最长为62.23 d，而33℃时仅为10.92 d；成虫寿命随温度升高而逐渐缩短，13℃时最长，为71.39 d， 33℃时最短，为11.95 d；各温度下净生殖率25℃时最大为31.42，13℃时最小为1.40；内禀增长力33℃时最高为0.21，13℃时最小为3.87×10-3；各温度下的稳定年龄组配29℃下最稳定，具体分布为：卵，36.54%；1龄，22.95%；2龄，7.56%；3龄，11.05%；4龄，10.11%；蛹，5.65%；成虫，6.13%。
英文摘要： Life tables of laboratory population of Hippodamia variegate (Goeze) were constructed at six temperatures. The results showed that the developmental rate increased with the temperature increasing from 13℃ to 33℃。The longest duration of one generation was 62.23 days observed at 13℃, and the shortest was 10.92 days at 33℃. The adult lifespan was shortened with temperature increasing. The longest lifespan was 71.39 days at 13℃, while the shortest was 11.95 days at 33℃. Net reproduction rate (R0) of 25℃ was the biggest one (31.42), and the smallest one was 1.40 at 13℃.The highest intrinsic growth rate (rm) was 0.21 at 33℃, while the lowest was 3.87×10-3 at 13℃. Stable age distribution at 29℃ was most stable, in which cluded 36.54% egg, 22.95% 1st instar, 7.56% 2nd instar, 11.05% 3rd instar, 10.11% 4th instar, 5.65% pupa, and 6.13% adult.
