A preliminary test on the toxic effects of abamectin+chlorpyrifos,EC,chlorpyrifos and lambda cyhalothrin on the Semanotus bifasciatus (Motschulsky) was carried out in Beijing Forestry University Forest Protection Laboratory in March 2007.The results showed that all the 3 pesticides could kill the adults of Semanotus bifasciatus (Motschulsky),but the effect of the chlorpyrifos was the most obvious,and the mortality rate in 5 days reached to 94.7%.Then field experiments were done with the Beta cypermethrin,abamectin+chlorpyrifos,E.C and profenofos in Mushi Forest Farm,Shandong province in 2008.The results indicated that the Beta cypermethrin 2000 times liquid was the most effective and economical,and that the pesticides did not change the attractive effect of trap log.
