中文摘要:采用田间调查和室内实验 ,研究了多异瓢虫的种群消长规律和捕食功能 ,表明该虫在棉田发生量大 ,发生时间长 ,幼虫、成虫对棉蚜的功能反应均为 Holling-Ⅱ 型 ,并随着幼虫的生长其捕食量逐渐增大。
英文摘要:The population dynamics and predacious function of Hippodamia (Adonia) variegata (Goeze) were studied through field survey and laboratory experiments.The results showed that the species has a large population and a long existing period in cotton fi
