冈崎姬小蜂对美洲斑潜蝇功能反应研究

The functional response of parasite Neochrysochans okazakii Kamijo on the vegetable leafminer Liriamyza sativae Blanchard

摘要: 研究3种大小不同的空间内冈崎姬小蜂对美洲斑潜蝇不同密度的功能反应,结果表明,在小容器内进行的功能反应结果符合HollingⅡ型;但在较大空间内,模拟自然界中同时存在不同密度的寄主幼虫时,冈崎姬小蜂对美洲斑潜蝇幼虫的寄生是随机的;寄生蜂个体间存在明显的干扰作用。

Abstract: The functional response between N.okazakii and L.sativae in small cages could be described as Holling I.However, when different density of leafminer existed in the large cage.the parasite gave a random response to the density of the leafminer,and the mortality of the leafminer was not aggregated in high density leave.There was an interference among parasites.
