摘　　要：大区域内实施柑橘木虱统防统治是控制柑橘黄龙病的关键措施,也是难点。本试验研究R44型直升机施药防治柑橘木虱的可行性和效果。在连片柑橘园,利用R44型直升机喷洒30%噻虫嗪悬浮剂防治柑橘木虱,施药3、7和10d后,柑橘木虱的虫口减退率分别为84.2%、84.8%和85.0%,防治效果分别为85.3%、87.7%和89.6%;对果树无损伤。试验结果表明,利用R44直升机施药进行柑橘木虱大面积防治可行有效,是一种省工、快速、高效的施药方式,值得大面积推广应用。Large-scale control of Diaphorina citri is the key and difficult point to control Citrus Huanglongbing.Feasibility and control efficacy of thiamethoxam30% SC against D.citri using R44 helicopter were investigated in large-scale cultivation citrus orchards.The results showed that 3,7 and 10 days after spraying,the decrease rates of D.citri were 84.2%,84.8% and 85.0%,and the control efficacies were 85.3%,87.7% and 89.6%,respectively.There was no damage on citrus trees.Large-scale control of D.citri using R44 helicopter is a practicable and effective,labor-saving,fast and highly efficient pesticide application method,which can be recommended to popularize and apply in the control of D.citri.
