| Abstract: | According to our investigations in the wheat fields of Heze Prefecture,there are98 species of natural enemies, of which 80 species are predatory and 18 species are parasitic.Population dynamics of the natural enemies was systematically observed and environmentfactors affecting population of the natural enemies were analysed.Predatory functions ofSyrphus corollae Fabricius,Epistrophe balteata De Geer and Coccinella seplempunctata Linnaeus to wheat aphids were also probed. |
