悬铃木方翅网蝽在豫南地区的发生及防治

Occurrence and Control of Corythucha ciliate Say in Southern Henan

悬铃木方翅网蝽是悬铃木树种的重要食叶害虫,2021年6月—2023年2月,按照《国家林业和草原局生物灾害防控中心关于做好2022年林草外来入侵物种普查工作总结的通知》(防控函[2022]57号)文件要求,对外来林业有害生物悬铃木方翅网蝽在豫南地区的发生危害进行了调查,弄清了铃木方翅网蝽在豫南平顶山、驻马店等地区的发生规律:一年发生2~3代,8月—9月发生危害,7月初出现成虫,7月下旬至9月中旬进入危害高峰期,同时探索出喷布1.2%烟碱·苦参碱乳油1800~2000倍液对悬铃木方翅网蝽的生物防治技术,为今后豫南地区防控悬铃木方翅网蝽提供了科学依据。

Corythucha ciliate Say is an important leaf-eating pest of Platanus acerifolia.From June 2021 to February 2023,according to the requirements of the Notice of the National Forestry and Grassland Administration Biological Disaster Prevention and Control Center on the Summary of the Survey of Forest and Grass Invasive Species in 2022(Prevention and Control Letter No.57),the occurrence and damage of the alien forestry pest Corythucha ciliata Say in southern Henan were investigated.It was found that Corythucha ciliata Say occurred in Pingdingshan,Zhumadian and other areas in southern Henan for 2~3 generations in one year,and the damage occurred from August to September,and the adults appeared in early July.From late July to mid-September,it reached the peak period of damage.At the same time,the biological control techniques of spraying 1.2% Nicotine·matrine emulsifiable concentrate 1800~2000 times on Corythucha ciliata Say was explored,which provided a scientific basis for the prevention and control of Corythucha ciliata Say in southern Henan in the future.
