在实验室条件下，对双带盘瓢虫捕食桔蚜进行了初步研究，用Ｈｏｌｉｎｇ－Ⅱ型和Ｈｏｌｉｎｇ－Ⅲ型功能反应新模型对双带盘瓢虫捕食桔蚜的作用进行拟合。结果表明，功能反应的数学模型为Ｎａ＝１．０８２０Ｎｔ１＋１．０８２０×０．０３３Ｎｔ和Ｎａ＝１３１．３４ｅｘｐ（－５０．９２Ｎｔ－１）。一头双带盘瓢虫对桔蚜的最佳寻找密度为５０．９２头。该瓢虫对桔蚜的捕食作用受自身密度的制约，相互间对捕食率存在干扰。
Under laboratory conditions, a preliminary study was conducted on the predation of ladybugs with ladybugs, and the effects of ladybugs on ladybugs were also fitted by a new model of Holing-Ⅱ and Holing-Ⅲ functional response. The results showed that the mathematical model of functional response was Na = 1.0820Nt1 + 1.0820 × 0.033Nt and Na = 131.34exp (-50.92Nt-1). The best looking density for aphids with a pair of ladybugs is 50.92 heads. The ladybug on the orange aphid predation by their own density constraints, mutual interference on the prey rate.
