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 experimental conditions, the predation function and their functional response to the population density of Myzus persicae adults and nymphs were studied. According to the data observed in the experiment, the model provided by Holling and W att respectively was used to simulate and the result of chi-square test showed no significant difference between the theoretical value and the measured value.
