摘要
为探索性信息素在稻纵卷叶螟Cnaphalocrocis medinalis(鳞翅目:螟蛾科)预测预报上的应用技术,2009年8月15日-9月20日在浙江省海宁市,对不同性信息素化合物配制诱芯的田间诱捕效果,以及性信息素群集诱捕、灯光诱捕和赶蛾3种不同方法监测成虫消长规律等进行研究。结果表明:在浙江地区以顺11-十八碳烯醛、顺13-十八碳烯醛、顺11-十八碳烯醇和顺13-十八碳烯醇以60μg∶500μg∶60μg∶120μg配制的PVC毛细管诱芯对稻纵卷叶螟的诱集效果最佳。通过性信息素诱捕、灯光诱捕和赶蛾3种方法的比较试验,初步结果显示性诱测报可取代传统的系统赶蛾法用于稻纵卷叶螟的预测预报。
The evaluation and optimization of synthetic pheromone blends of the rice leaf folder,Cnaphalocrocis medinalis were carried out in the rice fields in Haining City,Zhejiang Province between August 15 and September 20,2009 to explore its application for forecasting population. Three methods including sex pheromone traps,light traps as well as disturbing and counting method (DCM) for monitoring adult populations were compared. The results showed that the chemical blend of Z11-octadecenal (60 μg),Z13-octadecenal (500 μg),Z11-octadece-1-ol (60 μg) and Z13-octadecen-1-ol (120 μg) formulated in the PVC capillary tubing had the strongest attractiveness to male moths in Zhejiang,China. The preliminary data obtained from the comparison of pheromone traps,light traps and the DCM indicated the potential application of pheromone traps in monitoring population of the rice leaf folder.
