摘要
【目的】测定APF-I型化学诱剂的诱捕效果并监测松墨天牛等昆虫种群动态。【方法】通过使用APF-I型化学诱剂等4种不同诱剂和林缘外不同距离对松墨天牛进行诱捕试验。【结果】APF-I型化学诱剂的诱捕效果分别是A-3、FJ-MA-02、M-99诱剂的9.67倍、8.25倍和5.34倍;经测定其有效作用距离在150 m以上;诱获的昆虫种类多达31种,其中天牛11种,比率最高的是松墨天牛达73.76%,其次是椎天牛达23.29%。应用APF-I型化学诱剂监测松墨天牛等6种主要蛀干害虫发现:松墨天牛的初始期在4月底,出现了2个高峰期,第1个高峰期在5月底,第2个高峰期在7月上旬;椎天牛初始期在5月上旬,仅在5月下旬出现了高峰期。【结论】使用APF-I型化学诱剂诱捕是监测松墨天牛种群动态和降低其虫口密度的重要方法。
[Objective]This study was conducted to determine the trapping effects of APF-I type chemical attractant and to monitor the population dynamics of insects such as Monochamus allernatus Hope.[Method]Four different attractants,including APF-I type chemical attractant,and different distances outside the forest edge,were used to trap Monochamus allernatus Hope.[Result]The trapping effect of APF-I type chemical attractants was 9.67 times,8.25 times,and 5.34 times higher than that of A-3,FJ-MA-02,and M-99 attractants,respectively.After measurement,its effective action distance was above 150 m.There were up to 31 types of insects captured,including 11 species of longicorn,with the highest rate being 73.76%for the Songmo longicorn and 23.29%for the vertebral longicorn.The application of APF-I type chemical attractant to monitoring six main stem borers such as Monochamus allernatus Hope revealed that the initial period of Monochamus allernatus Hope was at the end of April,with two peak periods.The first peak period was at the end of May and the second was in early July.The initial period of the vertebrate beetle was in early May,and the peak period only appeared in late May.[Conclusion]APF-I type chemical attractant is an important method for monitoring the population dynamics and reducing the population density of Monochamus allernatus Hope.
