摘要
[目的]了解新疆地区松材线虫潜在媒介天牛种类,以及林间优势天牛种群发生动态,为新疆地区松材线虫病的监测和预防提供参考依据。[方法]以8种天牛信息素混合物、乙醇诱芯和(-)α-pinene诱芯3种不同信息素,在阿勒泰市太达雷克林场开展引诱试验;分析云杉林和落叶松林中诱集到的天牛种类组成及优势种群时间动态规律,比较不同诱芯、诱捕器不同悬挂高度和不同海拔下对2种优势天牛种类的引诱效果。[结果]不同诱芯诱集的天牛种类有3亚科5属6种,其中云杉大墨天牛和云杉小墨天牛为该区域优势种类。这两种优势天牛在6月上旬开始活动,7月份达到羽化高峰,诱捕量最大,随后诱捕量呈下降趋势。8种天牛信息素混合物诱芯对两种天牛的诱捕量高于其它诱芯的诱捕量,且明显高于乙醇诱芯和对照组。当诱捕器悬挂高度在0~6 m时,诱捕量随悬挂高度的增加而增加,但超过2 m时差异不显著。诱捕器悬挂于海拔1 200 km(山顶)时,两种优势天牛的诱捕量显著高于中低海拔的诱捕量。[结论]8种天牛信息素混合物诱芯在试验期间诱捕天牛诱捕量最高,适用于监测新疆地区松材线虫潜在媒介昆虫和潜在媒介昆虫的动态监测,在林间悬挂诱捕器时,建议悬挂在山顶、空旷的区域,并提升诱捕器悬挂高度在2~6 m,以便诱芯能充分扩散,提高引诱效果。这为新疆地区松材线虫病的监测预警与防控工作提供理论依据。
[Objectives]To understand the potential vector cerambycid beetles of pine wood nematode in Xinjiang and the population dynamics of dominant species in the forest,and provide reference for the mon-itoring and prevention of pine wood nematode disease in Xinjiang.[Methods]Three different attractants,i.e.,8 kinds of long horned beetles pheromone mixture,ethanol attractant and(-)α-pinene attractant,were used to trap long horned beetles in Taidalake Forest Farm of Altay City.The species composition and tem-poral dynamics of dominant species of long horned beetles trapped in spruce forest and larch forest were analyzed,and the attractive effects of different lures,traps with different suspension heights and different altitudes on the two dominant species of long horned beetles were also compared.[Result]There were 3 subfamilies,5 genera and 6 species of long horned beetles trapped by different lures,among which the dominant species in this area were the Monochamus sartor urussovi and the M.sutor.These two domin-ant long horned beetles began to move in early June,reached peak emergence and highest capture rates in July,and then gradually declined.The trapping amount of 8 kinds of long horned beetles pheromone mixture lures to two long horned beetles was higher than that of other lures,and was significantly higher than that of ethanol lures and control group.Trap height affected capture efficiency,with an increasing trend observed from 0 to 6 m,though differences became insignificant above 2 m.When the trap was sus-pended at an altitude of 1200 km(mountain top),the trapping amount of the two dominant long horned beetles was significantly higher than that at low and medium altitudes.[Conclusion]The mixed pher-omone lure of eight cerambycid species showed the highest trapping efficiency and is recommended for monitoring potential insect vectors of dominant long horned beetles in Xinjiang.For optimal monitoring,traps should be deployed in open,high-altitude areas(e.g.,mountain summits)and positioned at heights of 2–6 m to enhance pheromone dispersion and improve trapping efficiency.These findings provide a theor-etical basis for early warning and prevention of pine wilt disease in Xinjiang.
