摘　　要：用吡虫啉对台湾乳白蚁进行室内毒效试验和林间毒土屏障试验表明 :室内用w为 0 0 5 %的吡虫啉即可在 6d内全部杀死白蚁 ;林间毒土屏障试验用w为 0 0 5 %～ 2 0 0 %吡虫啉处理过的土壤 ,1a后观察发现台湾乳白蚁完全不能穿透 ,而用w为 0 0 5 %的毒死蜱处理过的土壤全部被白蚁穿透 ,并且松木块遭严重取食 林间同浓度比较试验 。The toxic efficacy and toxic soil barrier for termites ( Coptotermes fomosanus Shiraki) had been tested in laboratory and in forests respectively in Guangzhou. It is demonstrated that all termites were killed at the concentration of 0 05%(mass fraction)imidacloprid within six days in laboratory test, The termites did not tunneled through the toxic soil treated with 0 05%～0 20% (mass fraction) imidacloprid in barrier experiment. In contrast, all the plots treated with 0 05%(mass fraction) chorpyrifos were tunneled and consumed heavily by termites. It is concluded from these results that imidacloprid could be an excellent termiticide for protecting building from infestation by termites.
