摘要
引诱剂Ⅰ和引诱剂Ⅱ是最常用的2种松墨天牛引诱剂。为了弄清蛀干类害虫引诱剂林间诱捕云南松蛀干害虫的效果,于2009～2012年每年的5～9月蛀干害虫活动期在玉溪市红塔山自然保护区2个林区设6块样地进行2种蛀干害虫引诱剂诱捕蛀干类害虫实验。结果表明,蛀干类害虫引诱剂可以诱捕到危害云南松枝梢和树干的8种害虫,1种待鉴定,1种天敌昆虫。松墨天牛、短角幽天牛、吉丁虫、木蠹象、松瘤象是云南松蛀干害虫的优势群体。连续使用害虫引诱剂能显著降低林间蛀干类害虫的虫口密度。
Attractant Ⅰ and Ⅱ are the most commonly used two kinds of Attractants for Monochamus alternatus. In order to clarify the effect of moth attractant on trapping Pinus yunnanensis pests, experiment using two kinds of moth attractants to trap moth pests was conducted in two forest farm, on six sample plots of Hongtashan Nature Reserve during pest activity period every May to September from 2009 to 2012. Results showed that moth attractant could trap 8 kinds of pests damaged shoot and trunk of Pinus yunnanensis which one kind have to be identified, one kind was defined as natural enemy insects. Monochamus alternatus, germari, Holcocerus, etc. , could be main pests for Pinus yunnanensis. Continuous using of pest attractant might significantly reduce population density of moth pests.
