摘　　要：松毛虫赤眼蜂(Trichogramma dendrolimi Matsumura)是在实验室筛选出的一个赤眼蜂小种,结果表明,它在营养需求方面与苹果食心虫卵有很大的关联性。通过在相应的环境条件下,对寄主卵的密度、寄生虫和寄主卵密度比进行研究,同时建立数学模型,以评价使用松毛虫赤眼蜂防治苹果食心虫的高效性。Trichogramma dendrolimi Matsumura was a microspecies screened out in the experiment. The experiment showed there was a close relationship between the demand of the nutrition and the eggs of the apple budworms. The density of eggs of the host and the density proportion between the pest and the eggs of the host were analyzed,and the mathematical model was constructed in the relative experimental environment to illustrate the high efficiency of using Trichogramma dendrolimi Matsumura to prevent and cure the apple budworms.
