| 研究以松褐天牛（Monochamus alternatus）的聚集信息素壬醛 N 为主要配方，评价了壬醛对
松褐天牛的林间引诱作用。结果显示，松褐天牛雄虫产生的信息素 N 不但能诱捕到松褐天牛雌虫，也能
诱捕到雄虫，雌雄性比为 1 : 0.60；聚集素 N 与植物源信息素和小蠹聚集信息素之间有显著增效作用；在
广州市花都区全年都能诱捕到松褐天牛成虫，4-8 月为诱捕量高峰期。聚集素引诱剂 N 可以作为防治松

| Abstract: |
| In this study, the pheromone Nonanal(N), which is an aggregation pheromone produced by
males of Monochamus alternatus, was used as the main formulation to evaluate the inter-forest attraction to M.
alternatus. The results showed that the aggregation pheromone attractant N was able to trap both the female and
male of the pine sawyer beetles at the same time, and there was a very significant synergistic effect after added
the host-plant volatile and bark beetle pheromones into N. The adults of M. alternatus can be trapped through the
whole year in Huadu, Guangzhou, and the peak period of trapping is from April to August. This research lays a
good foundation for the pheromones attractants, and provides more effective technical means for the control of M. alternatus and pine wood nematode disease. |
