摘要
利用汞灯、黑光灯和引诱剂 3种诱源 ,在不同地点同时进行了松墨天牛种群发生动态监测试验 ,结果表明松墨天牛在象山非防治区林分中种群分布均匀 ,种群结构稳定 ,雌性比为 4 3%。汞灯和黑光灯均能取得良好监测效果 ,黑光灯成本低于汞灯 。
Population dynamics of Monochamus alternatus Hope was monitored with three kinds of traps,i.e.450W(GGC)light,20W light and chemical attractant at three different sites in Xiangshan County,Zhejiang Province.Results showed that the population dynamics was well monitored with 450 W(GGC)light and 20W light.The Japanese pine sawyer distributes uniformly in Xiangshan,with female adults contribute 43% to the total.
