摘要
日本高姬蝽(Gorpis japenicus Kerzhner)是柿零叶蝉(Limassolla diospyriChou et Ma)的天敌。1年1代,以卵在树皮缝中越冬。其成虫和若虫对柿零叶蝉的功能反应是HollingⅡ型曲线,当柿零叶蝉密度较低时,日本高姬蝽对柿零叶蝉起到一定的控制作用.随着日本高姬蝽虫龄的增长,取食量增大,其中5龄若虫和成虫的捕食作用较大.
Gorpis japenicus Kerzhner is a natural enemy of Limassolla di-ospyri Chou et Ma. The insect, reproducing one generation per year survive winter in the bark cract of persimmon by ova. The functional reactions of the adult and the nymph of G. jaoenicus to L. diospyri accord with the Holling II curve. G.japenicus can get L. diospyri under control when the population density of L. diospyri is lower, and it's predacious amounts increase with increasing of their age in days. The predacious ability of fifth instar nymph and adult is larger.
