摘要
对马尾松毛虫卵寄生蜂、幼虫寄生性天敌黑足四眼姬蜂、寄生蝇类和幼虫及蛹寄生蜂黑点瘤姬蜂在松毛虫种群中寄生行为的空间模式进行分析研究,结果表明,它们多属于负二项分布.这与其寄主的空间分布相吻合.寄生性天敌的这种寄生行为,有利于对害虫种群进行抑制.
Studies on spatial distribution patterns of parasitic behavior of egg parasitic waspe,larvaeparasitic Cast;mria in'gripes, parasitic flies and larvae or pupae parasitic Xanthonimpla Pedatorwith in the population of Dendrofilnus punctatus have been made.The results show that most ofthe distribution patterns present a negative binomial distribution and coincide with that of thehosts.The parasitic behavior of the parasitic natural enemy is favourable to the restraint of theinjurous insect population.
