| 摘 要： | 杨干象是为害2~6年杨树中幼林的主要蛀干害虫,严重危害杨树的生长和成材。通过采用钻孔注药方式对4-6年生杨树杨干象幼虫进行防治试验,结果表明:40%氧化乐果乳油+2.5%高效氯氟氰菊酯+50%久效磷乳油(1∶0.5∶1)混合液10倍液,每厘米胸径注射剂量1.0mL时,防治效果最好,虫口减退率达90.77%,防治效果达86.82。钻孔注药低污染、防治率高、易于操作、成本低,可在林业生产中普及推广。

| Abstract: | Cryptorrhynchus lapathi is the main borers which damaged half-mature & young forest for poplar,which seriously harm the growth.Through injecting pesticides into drilled-hole in trunks of 4-6-year-old poplar to control Cryptorrhynchus lapathi.Result shows that mixed solution 10 times:40% omethoate EC + 2.5% high efficiency chlorofenolin + 50% monocrotophyll EC (1∶0.5∶1) was used to control the larvae of Populus euphratica;DBH injection dose per centimeter is 1.0 mL;the control effect is optimal;insect population reduction rate is 90.77%;control effect is 86.82.Method of injecting pesticides into drilled-hole in trunks has the characteristics of low pollution,high control rate,easy to operate,low cost and it can be popularized in the promotion of forestry production. |
