摘要
剑湖湿地保护区杨树不断出现枯倒木、风折木,究其根本原因为虫害所致,经过2年的调查研究与试验分析,剑湖湿地保护区主要的蛀干害虫是麻点豹天牛(Coscinesthes salicis Gressitt)、杨干透翅蛾(Shecia siningensis Hsu),主要的食叶害虫是杨枯叶蛾(Gastropacha populifolia Esper)、背刺蛾(Belippa horrida),通过树干解析等方法发现杨树受害率已高达100%,针对调查发现问题,提出适合保护区实际并兼顾环保高效、易于操作的防治措施建议,为后续的杨树虫害防治提供参考。
In Jianhu Wetland Reserve,poplar trees are constantly falling down and broken by wind.The root cause is insect damage.After two years of investigation and experimental analysis,The main dry-bores in Jianhu Wetland Reserve are Coscinesthes salicis Gressitt,Shecia siningensis Hsu,The major leaf-eating pests are Gastropacha populifolia Esper and Belippa horrida,which have been found through tree trunk parsing and other methods to have a 100% damage rate on poplar trees,and in response to the problems found in the survey,In order to provide reference for the subsequent pest control of poplar,the author proposed some prevention and control measures which are suitable for the nature reserve and take into account environmental protection,high efficiency and easy operation.
