摘　　要：以25℃为对照,比较了花角蚜小蜂雌成虫在5、10、15、33、36、38℃温度胁迫下逐日产卵量和存活情况。结果表明:温度胁迫对花角蚜小蜂的逐日产卵量和存活均产生显著影响(P<0.01),过高或过低的温度都不利于花角蚜小蜂的产卵和存活。花角蚜小蜂产卵和存活的适宜温度为20～30℃。This paper dealt with the effects of temperature stress on survival and fecundity of Coccobius azurnai Tachikawa by 5℃, 10℃ ,15℃ ,33℃ ,36℃ and 38 % by taking 25 ℃ as control. The results showed that there had significant effects both on survival and fecundity in different temperature stress （ P 〈 0. 01 ）. Higher or lower temperature was disadvantage to Coccobius azumai Tachikawa survival and fecundity. The suitable temperature for survival and fecundity of Coccobius azurnai Tachikawa was 20 - 30 ℃.
