Abstract: Field experiments of different insecticides on wheat sawfly in wheat heading stage were carried out in 2010. The results showed that in the 3~4 instar larval height stage，when using chlorpyrifos 48% EC 600~900 g/hm2、phenthoate 50% EC 450~1 050 g/hm2、trichlorfon 98% crystal 750~1 500 g/hm2 and 4.5% Lambda-cyhalohrin EC 300~450 g/hm2，the control effect reached above 95% 16~40 h later. The variation analysis of the different processing methods were not significant.
