| 摘 要： | 为有效利用天敌防治烟草害虫,对大草蛉的生活史和烟田消长规律进行了调查研究,结果发现大草蛉在云南红河州弥勒烟区发生世代为5～6代.大草蛉卵的颜色随胚胎发育而变化,卵色变化以第4代所用时间最短.6月下旬至7月上旬是大草蛉成虫在烟田的第一个发生高峰期,8月下旬至9月上旬,是大草蛉成虫在烟田中发生的另一个高峰期.大草蛉在烟田的消长规律呈“双峰型”曲线变化.

| Abstract: | For effectively using natural enemies to control tobacco pests,the life cycle and population dynamics of Chrysopa pallens(Rambur) in tobacco field were investigated.The results showed that the insect produced 5-6 generations in tobacco growing area in Mile,Honghe Prefecture,Yunnan.Its egg changes color along with the embryonic development,and the duration of egg color changing was the shortest in the 4th generation.From late June to early July was the first peak of adult occurrence in tobacco fields,from late August to early September appeared another peak.The population dynamics of Chrysopa pallens(Rambur) in tobacco field presented a double-peak profile. |
