Abstract
[Objective] The aim was to explore effectively controlling method and measures which did not affect the ecological environment.[Method]The control effects of 1% soluble matrine liquid agent(smoke type),1.2% nicotine and matrine EC and 1.8% avermectin EC against P.assimilis larvae were studied by using smoke-spraying technology in Castanopsis fissarehd forestry.[Result]The controlling effects of 1% soluble matrine liquid agent(smoke type),1.2% nicotine and matrine EC and 1.8% avermectin EC against larvae of P.assimilis reached above 85% in four days.[Conclusion] The three regents could be used to control P.assimilis larvae.
