本文描述了群聚寄主卵和间隔分布的寄主卵对松毛虫赤眼蜂子代分配的影响。单头雌蜂产卵于群聚寄主卵时,平均每粒寄生卵的子蜂数明显少於单粒寄主卵时的子蜂数,但每头雌蜂所产的总子蜂数和被寄生的寄主卵数随着寄主卵群的卵数增加而增加。表明,雌蜂产卵于群聚寄主卵时能减少在每粒寄主卵中所分配的子蜂数,而增加寄生的寄主卵数目。密度制约是限制每头雌蜂寄生寄主卵数目的因素。在分散的寄主卵中,平均每粒寄生卵的子蜂数随着卵粒间距离增加而增加,但每头雌蜂所产的总子蜂数和被寄生的寄主卵数并没有明显地随着寄主卵粒间的距离大小而改变。可见,在分散寄主卵中,雌蜂的生殖力则是限制每头雌蜂寄生寄主数目的一个重要因素。 This article describes the effect of clustered host eggs and interspersed host eggs on the distribution of Trichogramma dendrolimi. When the single-headed female was spawning eggs in the cluster host eggs, the average number of the number of the parasites per parasitic egg was significantly less than the number of the number of the number of the single-parasitized eggs, but the number of the total number of the queens and the parasites The number of host eggs increases with the number of eggs of the host eggs. The results showed that females laid eggs in grouping host eggs can reduce the number of sub-bees distributed in each host egg and increase the number of parasitized host eggs. Density constraints are factors that limit the number of parasitic host eggs per female. In scattered host eggs, the average number of parasitoids per parasitoid increases with the distance between the eggs, but the number of total number of parasites and host eggs parasitized by each female is not significantly Host the size of the distance between the eggs and change. It can be seen that the fecundity of females in the dispersed host eggs is an important factor that limits the number of parasitized hosts per females.
