摘　　要：通过田间试验研究解放9型农用飞机喷洒吡蚜酮水分散粒剂和吡蚜酮·醚菊酯悬浮剂对水稻稻飞虱的防治效果。结果表明,飞机喷药雾滴分布均匀,穿透性强,水稻上部叶片平均药滴覆盖密度17.9个/cm2,中部叶片平均为13.5个/cm2。药效调查结果表明,飞机喷洒吡蚜酮水分散粒剂和吡蚜酮·醚菊酯悬浮剂对水稻稻飞虱防治效果好,药后1 d虫口减退率达83.06%,药后5 d达92.97%以上,药后7 d为96.0%。综合该结果,飞机施药适用于水稻稻飞虱的大面积防治。The efficiency of spraying Pymetrozine WDG and Pymetrozine.etofenprox SC to control rice plant-hoppers by Jiefang-9 agricultural aircrafts were studied through the field experiments. The results showed that the pesticide droplets were well-distributed and had strong permeability. The density of the droplets on the upper leaves was 17.9 per square centimeter, and that on the middle leaves was 13.5. Point-survey method was used to evaluate the control effect, showing that the pesticides above mentioned sprayed by agricultural aircrafts were able to control plant-hoppers well. The ratio of the plant-hoppers population reduction 1, 5 and 7 days after treatment with Pymetrozine WDG and Pymetrozine.etofenprox SC was 83.06%, 92.97% and 96.0%, respectively. It could be concluded that spraying pesticides by agricultural aircrafts was suitable for plant-hopper control in large scale.
