摘 要 ：2007—2009年连续3年应用探照灯诱虫器和佳多自动虫情测报灯,并结合雌蛾卵巢解剖对稻纵卷叶螟种群进行了监测。结果表明:探照灯诱虫器能有效监测稻纵卷叶螟种群动态,其数量变化规律与佳多测报灯灯下虫量变化规律基本一致,监测峰次多于佳多灯。探照灯诱虫器对稻纵卷叶螟的诱蛾量显著高于佳多灯,且对起飞迁出、过境、迁入降落虫群均具有较强诱捕作用。据此提出了以探照灯诱虫器、佳多测报灯诱虫突增情况和雌蛾卵巢解剖情况为标准的探照灯诱虫器诱蛾虫源性质判断方法,并以此方法,对探照灯诱虫器诱捕迁入、过境和迁出稻纵卷叶螟进行了个例分析。

Abstract:The study of using vertical pointing searchlight trap for monitoring the dynamics of Cnaphalocrocis medinalis Guenée were conducted at Xing‘an County in Guangxi Zhuang Autonomous Region from 2007 to 2009. The results showed that the vertical pointing searchlight trap could monitor the population dynamics of C.medinalis effectively. The peaks of catches on the vertical pointing searchlight-trap were more than that of the Jiaduo light trap. The vertical pointing searchlight trap could catch much more moths than Jiaduo light trap, including the immigration, passing and emigration airborne populations of C.medinalis. So that the peaks of catches on the two kinds of traps and the ovarian developmental level of the female in the vertical pointing searchlight trap would be able to determine the characteristics of C.medinalis. According to this method, three case studies of immigration, passing and emigration airborne populations of C.medinalis were conducted in this paper.
