飞机超低量喷雾防治天山野果林苹果小吉丁防效研究

【目的】研究飞机超低量喷洒2;噻虫啉微胶囊悬浮剂防治天山野果林苹果小吉丁防治效果，为防控天山野果林苹果小吉丁提供理论基础。【方法】通过对飞机防治作业前后作业区与对照区虫口密度调查，计算虫口减退率及防治效果。【结果】飞机防治作业区虫口减退率达到95.00;，防治效果达到65.82;。【结论】飞机超低量喷雾防治天山野果林苹果小吉丁，作业效率高，防治成本低，取得了较好的防治效果，在苹果小吉丁严重危害区域，可以大面积推广使用。

Preliminary Exploration of the Control Effect of Aerially Spraying to Control Agrilus mali Matsumura with Ultra-low Volume in Wild Fruit Forests

Objective]Preliminary research on the effect of aerially spraying 2; thiacloprid aqueous capsule suspense to control Agrilus mali Matsumura in wild fruit forests in order to provide a theoretical basis for theoretical basis for scientific prevention and control.[Method]The population density of Agrilus mali Mat-sumura were investigated in the survey sample plots and control plots before aircraft spraying.The population density of Agrilus mali Matsumura was also investigated in the survey sample plots and control plots after air-craft spraying.Then the rate of decline of insect and its prevention and cure effect was calculated.[Result]In the aerially spraying area,the reducing rate reached 95 .00;,the control effect reached 65 .82;.[Conclu-sion]The aerially spraying to control Agrilus mali Matsumura with Ultra-low volume in wild fruit forests in Tianshan Mountain has had high efficiency,low cost,and achieved good control effect,which can be applied in large area where Agrilus mali Matsumura seriously damaged wild apple trees.
