稻飞虱及黑肩绿盲蝽在探照灯下的扑灯节律

为明确稻飞虱及其天敌黑肩绿盲蝽在探照灯下的扑灯节律，2012和2013年在广西兴安县应用探照灯诱虫器对稻飞虱及黑肩绿盲蝽进行了分时段监测。结果表明：稻飞虱和黑肩绿盲蝽年度间扑灯量有所不同，夜晚扑灯类型属于整夜扑灯型，晚上一般有1~2个扑灯高峰。2012年稻飞虱和黑肩绿盲蝽、2013年白背飞虱在迁入高峰期扑灯高峰不固定，2013年褐飞虱扑灯高峰主要集中在19：30～21：00时段，黑肩绿盲蝽2013年扑灯高峰主要集中在00：00～01：30和01：30～03：00时段。稻飞虱和黑肩绿盲蝽迁出高峰期及黑肩绿盲蝽本地活动期扑灯高峰主要集中在前半夜，稻飞虱本地活动期扑灯高峰主要集中在前半夜和04：30～06：00时段。

Rhythm of rice planthoppers and Cyrtorhinus lividipennis to the searchlight trap

In order to elucidate the rhythm of rice planthoppers, Nilaparvata lugens and Sogatella furcifera, and their natural enemy plant bug, Cyrtorhinus lividipennis, to the searchlight trap in the night, a time-dividing monitoring of rice planthoppers and C.lividipennis during different periods was conducted with the searchlight trap in Xing'an County, Guangxi Zhuang Autonomous Region from 2012 to 2013. The results showed that catch amount of rice planthoppers and C.lividipennis were different between 2012 and 2013. Generally, insects could be trapped during the whole night with one or two peaks. The peak times of rice planthoppers and C.lividipennis in 2012, S.furcifera in 2013, to searchlight trap, during immigrant peak periods, were not stable. Peak times of N.lugens to searchlight trap in 2013, during immigrant peak periods, were mainly in 19:30-21:00, and C.lividipennis were mainly in 00:00-01:30 and 01:30-03:00. During emigrant peak periods of rice planthoppers and local action of C.lividipennis, insects were captured mainly before mid-night. Peak times of rice planthoppers to searchlight trap, during local action, were mainly before mid-night and in 04:30-06:00.
