By comparing and analyzing its predatory potential, we consider that both L. axyridis’ preying on A. glycines and on R. maidis were fitted with type II response, which can be simulated by Holling disc equation, and expressed as: Na 0.6792N/ (1 0.0022N) corn ? ? and Na 0.9463N/ (1 0.0023N) soybean ? ? , respectively. In addition, by comparing its functional parameters, we found that L. axyridis’ ability to control A. glycines is significantly stronger than that of R. maidis.Originating text in Chinese.Citation: Lin, Zhiwei, Wang, Liyan, Sun, Qiang, Nan, Shan.
