The metabolites of Paecilomyces arovirens exhibited insecticidal activities tomany inscct pcsts, including cotton aphid, Aphis gossypii, hawthorn Ispidcr mitc,Tetranychus viennensis and larvae of imported cabbage worm, Pietis rapae. Acompanson was made between the metabolites of P.arovirens and naphthye acetic acid(NAA) in wheat (Triticum aestivum) and water melon (Cucumis sativus) bioassays ontheir physologieal effects. Results demonstrated that some of the metabolitesphysiological activities of P. arovirens are same to that of NAA, some are differentbetween them. It indicate that there is a new kind or many kinds of plant growthregulator in the metabolites and need further analysized. The results can offerreference for exploiting a new insecticid which not only can control insect pests, butalso increase plant growth. 展开更多
