摘　　要：本试验比较了不同湿度下冷藏米蛾卵对螟黄赤眼蜂寄生和羽化的影响,并编制了米蛾卵繁育的螟黄赤眼蜂在亚洲玉米螟卵上的实验种群生命表。结果显示,在冷藏12 d及更长时间的米蛾卵上,赤眼蜂单雌产卵量显著低于对照;米蛾卵冷藏30 d及更长时间,在相同的冷藏天数下,RH97.7%下冷藏的米蛾卵上的赤眼蜂单雌产卵量,均显著高于RH37.3%组;米蛾卵繁育的螟黄赤眼蜂在亚洲玉米螟卵上的单雌平均产雌率R0'=1.4728,雌性比率P♀=0.7523,世代的平均历期T=9.9146。The test compares the impacts of C. cephalonica eggs on the parasitism and emergence under the cold storage in different humidity on the one hand,and formulates the experimental population life table of T. chilonis bred by C. cephalonica eggs on O. furnacalis. The result shows that as for the C. cephalonica eggs under the cold storage for 12 days or more,the egg number per female of T. chilonis is notably lower than that in control group; as for the C. cephalonica eggs under the cold storage for 30 days or more,the egg number per female of T. chilonis on C. cephalonica eggs stored under RH97. 7% is obviously higher than that in the group under RH37. 3% at the same days for storage; the average female laying rate per female T. chilonis bred by C. cephalonica eggs on O. furnacalis R 0 ＇ = 1. 4728,the female proportion P ♀ = 0. 7523 and the average immature period T = 9. 9146.
