不同引诱剂与林分因子对松褐天牛诱捕效果的影响

Influences of different attractants and forest factors on the trapping effect of Monochamus alternatus

在江西省阳明湖国家森林公园选取马尾松林地,悬挂松褐天牛诱捕器,对诱捕效果进行观测,分析不同引诱剂与林分因子对诱捕效果的影响,筛选出适宜的引诱剂类型及松褐天牛诱捕器最佳悬挂方法。试验结果表明:试验区内5月上旬和6月上旬松褐天牛活动最密切;两种引诱剂诱捕雌性松褐天牛数量显著高于雄性;在不同引诱剂与林分因子的影响下,各松褐天牛诱捕器诱捕数量差异显著,诱捕器悬挂在松林的南坡、东南坡、西南坡等向阳面、通风处,诱捕效果最佳,不同悬挂位置诱捕效果:山脊>防火线>林缘>水域周边;在海拔高度200~300 m之间诱捕松褐天牛数量最多;两种引诱剂对松褐天牛都有引诱效果,F8增强型引诱剂每套诱捕51.44头,APF-1型引诱剂每套诱捕32.61头。

In the Yangming Lake National Forest Park in Jiangxi Province,select Pinus massoniana forest lands,hang Monochamus alternatus traps,observed the trapping effect,and analyzed the influence of different attractants and forest factors on the trapping effect,and screened out suitable attractant type and the best suspension method of M.alternatus traps.The test results showed that the activity of M.alternatus in the experimental area was the most intense in early May and early June;the number of female M.alternatus being trapped by the two attractants was significantly higher than that of males;under the influence of different attractants and stand factors,the trapping numbers of M.alternatus are significantly different.The traps hanging on the south slope,southeast slope,southwest slope of the pine forest and other sunny surfaces and ventilated places showed the best trapping effect.The trapping effect of different hanging positions:ridge>fire forest belt>forest edge>lakeside;the number of M.alternatus being trapped at the altitude of 200~300 m was the largest;both two types of attractants had a lure effect on Monochamus alternatus,F8 enhanced attractant trapped 51.44 heads per set,APF-1 attractant trapped 32.61 heads per set.
