摘要：

This research aimed to study the,effects of different insecticides, herbicides and fungicides on eggs, larvae and pupae of Trichogramma pretiosum. The results showed that studied pesticides had different impact on T. pretiosum Esfenvalerate 7.5 and spinosad 24.0 grains ha(-1) were classified as harmfull (class 4) while clofluazuron 10.0, methoxfenozide 19.2, lactofen 165.0, fomesafen 250.0, flitozifop 125.0, glyphosate 960.0 (Gliz (R) and Roundup Transorb (R)), ozoxistrobin + ciproconazol 60.0 + 24.0, ozoxistrobin 50.0 and myclobutanil 125.0 grains ha(-1) were chemicals classified as harmless to all imature T pretiosum stages. All the other chemicals evaluated had different impact on T pretiosum being classified from harmless (class 1) to harmful (class 4) varying the impact according v to the different parasitoid stage. Then, less noxious products should be chosen whenever possible to be used in a soybean IPM program.
