树干注药对天然胡杨林蔡氏胡杨个木虱的防控效果

Preventive and Control Effects of Trunk Injection on E.Ceardi in the Populus euphratica Forest Area of Ejina Banner

为精准有效防控额济纳旗胡杨林区蔡氏胡杨个木虱的发生,通过田间树干注药试验,研究了15%的乙酰甲胺磷注剂和12%的阿维菌素注剂2种药剂对胡杨林区蔡氏胡杨个木虱的防控效果。结果表明:2种注干药剂对蔡氏胡杨个木虱均有一定的防控作用,并且持续时间长。施药后的10、20、30、40 d,通过观察危害的叶片得出15%的乙酰甲胺磷注剂对于蔡氏胡杨个木虱的防治效果均较12%的阿维菌素注剂防治效果好;2种注干药剂在施药30d后防治效果达到最好。同时由于胡杨林区木虱与网蝽混合发生,在胡杨林区防效调查过程中通过观察发现树干注药对胡杨林区的网蝽也具有较好的控制效果。

To precisely and effectively control the occurrence of Egeirotrioza Ceardi Bergevin in the Populus euphratica forest area of Ejina Banner,this study investigates the preventive and control effects of two trunk injection agents,15%acephate and 12%abamectin,on E.Ceardi in the forest area through in-field trunk injection experiments.The research demonstrates that both trunk injection agents exhibit a certain degree of control effect on E.Ceardi,with a prolonged duration.At 10,20,30,and 40 days post-treatment,it was observed through the examination of affected leaves that the control effect of 15%acephate injection agent was superior to that of 12%abamectin injection agent for E.Ceardi.The two injection drying agents achieved the best control effect after 30d application.Meanwhile,due to the mixed occurrence of E.Ceardi and Monosteira unicostata in the poplar forest area,it was observed during the investigation of control efficacy in the poplar forest area that the trunk injection treatment also had a relatively good control effect on M.unicostata.
