靖远松叶蜂性信息素诱捕器的应用技术

The Application of Traps with Sex-pheromone of Diprion jingyuanensis

靖远松叶蜂对人工合成的性信息素的昼夜反应节律发生在白天 ,反应时间从早晨 9:0 0开始一直持续到下午 16 :0 0结束 ,反应高峰为 11:0 0～ 14 :0 0 ,反应模式为“单峰式—白天型” ;对其成虫发生期的监测显示 ,不同年份和海拔高度的成虫发生期不同 ,成虫一般的羽化开始时间为 5月 31日左右 ,高峰期为 5月 17日左右 ,羽化末期为 7月 2 8日 (低海拔林分 )和 8月 2 6日 (高海拔林分 ) ,成虫持续期为 5 9d(低海拔林分 )和 89d(高海拔林分 )左右 ;对分布区域的检测表明 。

The field experiments with the application of Lund-I traps with sex-pheromone of Diprion jingyuanensis were carried out in the Pinus tabulaeformis Carr. Plantations in Qingyuan County of Shanxi Province, China from 1998 to 1999. The response of males to Lund-I traps baited with sex-pheromone revealed a daytime attraction response pattern. Seasonal flight activity including flight initiation, duration, termination as well as the peaks as monitored by Lund-I traps baited with the synthetic sex pheromone varied with altitude of the sites, and D. jingyuanensis were found with Lund-I baited with sex-pheromone in Taiyueshan Forest Park where D. jingyuanensis did not occur before.
