摘要
在试验条件下,研究了南方小花蝽成虫及若虫对不同密度烟蚜的捕食功能以及其对自身密度的功能反应。根据试验所观测的数据,分别按Holling 和W att所提供的模型进行模拟,并经卡方检验,其理论值与实测值无显著差异。
Under the laboratory conditions, the functional responses of different stages of nymphs and adult of \%Orius similis \%Zheng to its prey \%Myzus persicae(\%Sulzer) were simulated using Holling & Watt models. The functional responses of the adult and nymphs to the preys can be described by the methods of Holling. A x\+2 test showed that the theoretical expectation fit the observed values(P<P\-\{0.05\}).
