墨天牛Monochamus galloprovincialis（Olivier）（鞘翅目：天牛科）是一种重要的二化螟，在欧洲被鉴定为松材线虫病的传播媒介。需要一种有效的诱捕方法作为管理这种昆虫媒介并允许早期检测线虫运输的工具。近年来鉴定的有效引诱剂中有特异性M。galloprovincialis聚集信息素，宿主松树利它素如α-蒎烯和树皮甲虫利它素如ipsenol和甲基-丁烯醇。本研究的主要目的是优化这些挥发物的组合，以提高引诱力和特异性。通过10次田间试验，发现诱捕器诱集物具有信息素剂量效应。引诱剂的最佳组合为聚集信息素+两种利它素，ipsenol和甲基丁烯醇。添加松油烯，如α-蒎烯，并没有显着提高M。galloprovincialis诱捕器捕获，但增加了非目标物种的捕获量，包括天敌。只有在优先考虑最大限度地消除病媒的情况下，才建议使用松萜烯。虽然这项研究已经导致开发了一种新的，非常有吸引力的商业引诱成熟的松树锯木蠹蛾，没有测试的混合物是成功地吸引未成熟的松树索耶成人。需要进一步的研究来开发这些甲虫的引诱剂。
Monochamus galloprovincialis (Olivier) (Coleoptera: Cerambycidae) is a secondary wood borer that acquired primordial importance since it was identified as the European vector of Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD). An effective trapping method is needed as a tool for managing this insect vector and allowing early detection of nematode transportation. Among effective attractants identified in recent years are the specific M. galloprovincialis aggregation pheromone, host pine kairomones such as alpha-pinene and bark beetle kairomones like ipsenol and methyl-butenol. The main objective of this study was to optimize the combination of these volatiles to improve lure attractiveness and specificity. Based on ten complementary field experiments, we found a pheromone dose-response of trap catches. The best combination of attractants was the aggregation pheromone plus two bark beetle kairomones, ipsenol and methyl-butenol. Addition of pine terpenes, such as alpha-pinene, did not significantly improve M. galloprovincialis trap capture, but did increase catch of non target species, including natural enemies. The use of pine terpenes would be advisable only if priorizing to maximize removal of vectors. While this research has lead to the development a new, highly attractive commercial lure for mature pine sawyers, none of the tested blends were successful in attracting immature pine sawyer adults. Further investigation is needed to develop attractants for these beetles.
