农一师3团棉铃虫成虫种群动态及三种测报方法比较研究

Population Dynamics and Three Forecasting Methods of Adults of Helicoverpa armigera (Hübner) in Regimental Farm 3 of the First Agricultural Division

对新疆生产建设兵团农一师三团2006年棉铃虫成虫种群数量的系统进行了调查。结果发现:5月17日至8月9日期间,棉铃虫共发生3代;比较黑光灯、杨树枝把和性诱剂3种测报方法,在棉铃虫二三代发生期,黑光灯诱蛾方法较准确,能较好地反映棉铃虫成虫的消长动态,与田间卵峰有较好的吻合性。

Through the investigation to adults of Helicoverpa armigera （Htibner） in regimental farm 3 of the first agricultural division, the results showed that there were three peaks from 17^th May to 9^th August. Based on the application of sex lure, black light and poplar twig bunch traps in 2006, the method of black light was the most accurately in three methods and could be used as the index to reflect population dynamics of H. armigera. It was consistent with egg peak preferably.
