通过不同饥饿程度七星瓢虫雌、雄成虫对麦二叉蚜捕食作用的研究,得出:①饥饿不能改变七星瓢虫雌、雄成虫捕食作用的功能反应类型;②七星瓢虫雌、雄成虫间在各种饥饿条件下的捕食量差异均不显著;③七星瓢虫雌、雄成虫对麦二叉蚜的捕食量(Na)随着时间(t)的变化,其模型分别是Na=90/1+e0.94534-0.15745t和Na=90/1+e0.87285-0.12985t;④七星瓢虫雌、雄成虫之间在24h内的捕食速度(V)差异不显著,其与时间段(x)关系的模型分别为V=8.3559x-1.2460和V=4.3487x-0.5964。
Through the research on the predation function of female and male adults of Dipterocarpaceae of different degree of starvation to wheat Aphis gossypii, we can conclude that: ① starvation can not change the functional response type of female and male adults of C. elegans; (3) The predation quantity of female A. diplopiae and A. mandarina on the time (t) varied with the time (t), and the model of their predation amount was Na = 90 /1+e0.94534-0.15745t and Na = 90/1 + e0.87285-0.12985t; (4) There was no significant difference in the predation rate (V) between female and male adults of Coccinella septempunctata within 24 hours, ) Are V = 8.3559x-1.2460 and V = 4.3487x-0.5964, respectively.
