| 摘 要： | 选用氧化乐果和甲拌磷乳油，采用环扎法和注孔法对杨干象进行防治的试验结果表明：在环扎法中，l／2环扎处理的氧化乐果的防效达94．84％；在注孔法中，2种药剂2孔注药处理的防效均在87％以上。因此，在防治杨干象时，若采用环扎法应选用氧化乐果乳油，并进行l／2环扎处理；若采用注孔法，2种药剂均可选用，且以2孔注药方法更简便、适用。

| Abstract: | The control of Cryptorrhynchus lapathi L. was done by using omethoate and phorate.The results showed that the control effect of omethoate treated with 1/2 loop bundle reached 94.84%;both of the pesticides treated with two holes injection reached more than 87%.Omethoate emulsifiable solution treated with 1/2 loop bundle and the two pesticides treated with two holes injection can be effectively used in Cryptorrhynchus lapathi L. control. |
