摘要：对小兴安岭落叶松毛虫卵期的寄生蜂进行了调查,共采集落叶松毛虫卵3292粒,通过室内饲养,发现3种寄生蜂。对松毛虫卵宽缘金小蜂、落叶松毛虫黑卵蜂、松毛虫赤眼蜂的寄生率、每卵出蜂数、雌雄性比进行了统计分析,寄生率分别为56.23%、35.66%、0.49%、总寄生率达92.38%;一粒寄主卵通常只育出1头宽缘金小蜂,育出松毛虫黑卵蜂平均为8头,最多13头,最少4头;宽缘金小蜂和黑卵蜂的雌雄性比分别为1.63∶1和1.47∶1。
The egg parasitoids of the larch caterpillar, Dendrolimus superans, were investigated in Xiaoxing'anling Mountains in 2002. Three parasitic species were obtained from the pest eggs, i.e., Pachyneuron solitarium (Hymenoptera: Pteromalidae), Telenomus tetratomus (Hym.: Scelionidae) and Trichogramma dendrolimi (Hym.: Trichogrammatidae). A total of 3292 eggs were collected at two forest areas by random sampling. The rearing results showed that the total parasitic rate of the three parasitoids was up to 92.38%, in which P. solitarium 56.23%, T. tetratomus 35.66%, and T. dendrolimi only 0.49%. The number of wasps emerged from a parasitized egg was only one for P. solitarium and 8 wasps (maximum 13 wasps) for T. tetratomus. The sex ratio of the wasps emerged from the parasitized host egg was 1.63∶1 for P. solitarium and 1.47∶1 for T. tetratomus.
