摘　　要：银杏超小卷叶蛾以幼虫蛀食危害银杏枝条,造成银杏的枯枝、落果、落叶,影响银杏生长和景观。研究制备20%呋虫胺可溶粒剂,采用树干基部打孔施药开展防治银杏超小卷叶蛾试验。在施药剂量为每棵树1粒和2粒时,施用1次,施药360 d后,在银杏枝干内可检测到呋虫胺残留;2 a内对银杏超小卷叶蛾均有良好的防治效果,第1年防治效果达到90%以上,第2年仍维持在80%以上。研究结果可为银杏超小卷夜蛾绿色防控提供新途径。Pammene ginkgoicola larvae feed on ginkgo branches,causing the death of branches,and falling of fruits and leaves,which affect the growth and landscape of ginkgo.In this study,20%dinotefuran soluble granules was prepared and drilled at the base of the tree trunk to control Pammene ginkgoicola.The results showed that 20%dinotefuran soluble granules had a good control effect within 2 years after applying once,with control effect above 90%in the first year,and above 80%in the second year.The results of the study could provide a new way for the green prevention and control of Pammene ginkgoicola.
