摘要
摸清不同饥饿处理对微小花蝽成虫捕食朱砂叶螨的功能反应和捕食速度的影响。采用叶碟法测定了微小花蝽Orius minutus(Linnaeus)成虫的耐饥饿能力,并研究了不同饥饿程度对其捕食朱砂叶螨Tetranychus cinnabarinus(Boisduval)成螨的功能反应和捕食速度的影响。微小花蝽成虫可忍受80h的饥72饿h的处微理小;不花同蝽饥成饿虫程24度h的内微对小朱花砂蝽叶成螨虫的捕捕食食朱作砂用叶主螨要成集螨中的在功开能始反捕应食均的可12拟h合,尤为其H是oll前ing4Ⅱh型内;,饥而未饿经饥饿处理的微小花蝽成虫的捕食作用则平均分布于整个测试时段。一定程度的饥饿处理不能改变微小花蝽成虫捕食功能反应的类型,但对其特定时段内的捕食速度有明显影响。
To make clear the influence on predatory functional response and predation rate of Orius minitus adult to Tetranychus cinnabarinus,the starvation tolerance of Orius minitus adult was examined by leaf disc test.Based on this,the influence on functional response and predation rate by Orius minitus adult to Tetranychus cinnabarinus at various levels of starvation were studied.The results showed that the adults of Orius minitus can endure starvation for 80 hours.The functional responses of adults of Orius minitus on various ranges of starvation to adult mites of Tetranychus cinnabarinus were fitted to HollingⅡ-types.The predation in 24hours of Orius minitus starved for 72 hours was concentrated in the first 12hours of the test,especially in the first 4 hours.While the predation of Orius minitus with no starvation allotted in the whole period of test.The functional response types of adults of Orius minitus were not altered by starvation duration within a certain range,but the predation rates in the specific period were affected obviously.
