摘  要:
利用混合及单一杀虫剂,采用注干、涂干等方法对松突圆蚧进行林间药效试验,同时对几种方法处理后的松突圆蚧种群消长情况进行跟踪调查。结果表明:注干和涂干法处理时,混合药剂的最佳组合均为40%杀扑磷乳油(V(杀扑磷乳油)∶V(水)=1∶5)+40%毒死蜱乳油(V(毒死蜱乳油)∶V(水)=1∶5)+40%氧乐果乳油(V(氧乐果乳油)∶V(水)=1∶2.5)混合,采用注干法和涂干法的防治效果分别达98%和81%,虫口减退较明显,而喷雾法处理的虫口波动较大。

摘  要:
The control effects of mixed and single insecticides against Hemiberlesia pitysophila in woods were tested.The best proportion of mixture with tree-trunk injection and lacquer by Orthogonal design was found.At the same time,the change of population by spray,trunk injection,trunk lacquer was investigated respectively.The results showed that the best mixing proportions with trunk injection and lacquer were the same as 40% methidathion EC(1∶5)+40% chlorpyriphos EC(1∶5)+40% omethoate EC(1∶2.5).The control effects with tree-trunk injection and lacquer were 98%,81% respectively,which both had remarkable synergisms.The observation of the population growth showed that the rates of population reducing of tree-trunk injection and lacquer were more steady than that of leaf-spray.
