摘  要:
Control experiments of 3-4 instars larvae of Latoia lepida by using 3 kinds of biological pesticides(1.8% Sendebao wettable powder,1.8% pyrethrum+matrine emulsion in water,1.2% Matrine) were conducted in forest.Result shows that 550 g·hm-2 Sendebao wettable powder have the most economical and effective control effect on Latoia lepida,being 90.13%;control effect of 450-150 mL·hm-2 1.8% pyrethrum+matrine emulsion in water on Latoia lepida is 83.29%-90.13%;control effect of 1.2% Matrine with 3 concentrations(750,650 & 550 g·hm-2) are all 100%,being the optimal.
