| 摘 要： | 华山松大小蠹Dendroctonus armandi Tsai et Li是危害我国华山松Pinus armandii的主要蛀干害虫。收集和测定华山松树皮和华山松大小蠹的挥发物,根据挥发物组分设计配制8种诱芯,采用漏斗诱捕器进行林间诱捕筛选试验;应用诱芯Ⅱ进行多点诱捕验证和有效诱捕距离试验。结果表明:诱捕期内,诱芯Ⅱ平均诱捕华山松大小蠹1 070头/诱捕器,显著高于其它7种诱芯;单个诱捕器一天最多诱捕1 652头。诱芯Ⅱ在3个地点的平均诱捕量差异不显著,分别为83,114,101头/诱捕器,诱捕效果不存在地理差异;距离林缘50 m处诱捕量为43.5头/诱捕器,为最佳有效诱捕距离。该华山松大小蠹高效引诱剂可为我国华山松大小蠹的治理提供新技术。

| Abstract: | Dendroctonus armandi is the main pest for Pinus armandii,causing tons of pines dead.In this study,based on components identified from bark and beetles,we made 8 kinds of lures and carried out field trapping with funnel traps.We applied lureⅡfor multi-site trapping verification and valid trapping distance test.The results showed that lureⅡaveragely caught 1 070 beetles per trap,which was significantly higher than other 7 lures.The maximum trapping amount of lureⅡwas 1 652 beetles per day per trap.The average trapping amount of lure II at three test sites were 83,114 and 101 beetles per trap,which had no significant difference.The average trapping amount of traps at 50 meters away from forest edge were 43.5 beetles per trap,showing the optimal valid trapping distance.This high efficiency lure would provide new technology for the management of D.armandi. |
