摘要
灰茶尺蠖和小贯小绿叶蝉是茶园的重要害虫,严重影响茶叶产量和品质。本文在调查灰茶尺蠖种群发生动态的基础上,测定了植保无人机喷施BT+藜芦碱混配药剂对灰茶尺蠖和小贯小绿叶蝉的防效。结果表明:BT+藜芦碱混配药剂对灰茶尺蠖药后3 d的防效为93.9%,药后7 d的防效为96.9%;对小贯小绿叶蝉药后3 d防效为73.3%,药后7 d防效为81.3%。综上所述,BT+藜芦碱混配药剂对灰茶尺蠖和小贯小绿叶蝉具有良好的防效,可兼治这2种害虫。
Ectropis grisescens and Empoasca onukii are important pests in tea garden,which seriously affect the yield and quality of tea.Based on the investigation of population dynamics of Ectropis grisescens,the control effect of BT and veratrine mixture sprayed by plant protection UAV on Ectropis grisescens and Empoasca onukii was determined in this paper.The results showed that the control effect of BT and veratrine mixture on Ectropis grisescens was 93.9%on the 3rd day and 96.9%on the 7th day;the control effect of BT and veratrine mixture on Empoasca onukii was 73.3%on the 3rd day and 81.3%on the 7th day.In conclusion,BT and veratrine mixture had good control effect on Ectropis grisescens and Empoasca onukii,which could be used to control the two pests at the same time.
