蝶蛹金小蜂Pteromalus puparum Linnaeus是菜粉蝶Pieris rapue Linne蛹寄生主要天敌。蝶蛹金小蜂在横断山(康滇地轴)中段,7～9月平均气温22.7～20℃,相对湿度75％的四川西昌等地,成蜂寿命3～6天,卵期1～1.5天,幼虫期6～6.5天,蛹期7天左右,完成一个世代需17～21天。成蜂饲以糖蜜的寿命4～10天,最长的达28天,证明田间蜜源条件对蝶蛹金小蜂种群数量可能有关系。蝶蛹金小蜂蛹态主要在
Pteromalus puparum Linnaeus is the main natural enemy of pupae parasitized by Pieris rapue Linne. Chrysalis golden pups in the Hengduan Mountains (Kang Dian axis) in mid-July to September the average temperature of 22.7 ~ 20 ℃, relative humidity of 75% of Xichang and other places in Sichuan, adult life span of 3 to 6 days, the egg period of 1 to 1.5 days Larvae 6 to 6.5 days, about 7 days pupal stage, to complete a generation to be 17 to 21 days. Into the bee feed molasses life of 4 to 10 days, the longest up to 28 days, to prove the field honey conditions on the population of the butterfly pupal population may be related. Chrysalis pupae golden pupal mainly in
