摘　　要：用40%的速扑蚧,的氧化乐果,灭蚧灵等药剂,采取树干打孔注药、树干韧皮部涂药、树干去粗皮涂药、树干直接涂药等4种茎部内吸法,对为害紫油厚朴的藤壶蚧进行化学防治试验。结果表明:3种药剂防治效果均达到100%,4种茎部内吸法中树干韧皮部涂药法有轻度药害,打孔注药法对树干有轻微损伤,且操作不便,采用氧化乐果树干直接涂药法防治成本最低,操作方便,可大面积推广使用。The chemical control experiment on Asterococcus muratae Kuwana which uses 40% of methidathion,omethoate,Mie Jie Ling etc.And the main methods are stem adduction ways such as injecting pesticide into the drilled hole of the trunk,applying pesticide to the phloem of the trunk,applying pesticide to the trunk which has been scraped off the coarse layer,applying pesticide directly to the trunk.The results showed that the control effect of the above three kinds of pesticides all reaches 100%.Moreover,methods of applying pesticide to the phloem of the trunk causes mild chemical injury,injecting pesticide into the drilled hole is unhandy and brings minor damage to the trunk.The best way is apply omethoate directly to the trunk for it has the lowest cost and easy to operate,thus,it can be widely used.
