摘要
室内饲养东亚小花蝽的捕食功能反应符合HollingⅡ型功能反应,捕食量随着猎物密度的增加而增加,搜寻效应随着猎物密度的增加而降低,对茶棍蓟马成虫捕食上限为26.25头;对小绿叶蝉2~3龄若虫捕食上限为19.68头;对小绿叶蝉卵的捕食上限为22.33头。
The predation behaviors of Orius sauteri on two pest insects of tea bushes were studied in laboratory. The results showed that the responses of O. sauteri toward the insects could be described by the Holling II equation. The predative activities of O. sauteri increased with increasing prey population, but the searching rate declined as the insect density was reduced. The maximum number of adult Dendrothrips minowai Priesner an O. sauteri could consume in a day was 26.25;whereas, it was 19.68 on 2- to 3-year-old nymphs or 22.33 eggs of Empoasca onukii Matsuda.
