| 摘 要： | 三突花蛛 ( Misumenops tricuspidatus ( Fabricius) )属蛛形纲 ( Arachnida)蟹蛛科( Thomisidae) ,经野外调查发现 ,是泰山上桃树 ( Prunus persica Sieb et Zucc.)害虫的重要天敌之一1,2 ] ,能捕食多种害虫 ,如桃小叶蝉 ( Erythroneura sudra ( Distant) )、桃粉蚜( Hyalopterus amygdali Blanchard)、朝鲜毛球蚧 ( Didesmococcuskoreanus Borchs.)等3] 。前两种是早春常见的害虫 ,而活动早的天敌以三突花蛛为主。害虫与捕食性天敌之间的关系 ,常用的数学模型有 Holling模型等4～ 8] 。但对多数树种 ,往往同时存在两种或两种以上…

| Abstract: | Misumenops tricuspidatus is a predator of Erythroneura sudra and Hyalopterus amygdali .Its selective coefficient varies with the amount change of these two pest populations.When the amount of both insect pest increase or the amount of E.sudra increases while H.amygdali keep unchanged, E.sudra is the priority to be caught.Only when the amount of H.amygdali increase while that of E.sudra keep unchanged and the ratio reached 20/10,the H.amygdali takes the precedence to be caught. |
