摘要
:石榴棉铃虫 (Heliothisarmigera (Hubner) ,属鳞翅目 (Lepidoptera) ,夜蛾科 (Noctuidae) ,是棉花的主要害虫 ,但也是云南蒙自石榴的主要害虫之一。但其发生危害规律尚不清楚 ,致使防治效果不佳。于 1 998～ 1 999年对该虫发生规模及综合防治进行了研究 。
Cotton bollworm ( Heliothis garmigera Hubner) is one of the major pests attacking Punica granatum in Mengzi County, Yunnan Province. Its larvae are borers which infest the flowers and young fruit of the plant, causing them to drop prematurely. Its occurrence shows an intermittent pattern, causing yield losses of 1.5%～3.5% in normal years and of 8%～15% in years when an outbreak occurs. In the present investigation made in Mengzi, it was found that the pest had six generations in a year, which overlapped greatly. Its larvae did not hibernate in winter. The second and third generations of the pest attacked P.granatum . Integrated control gave promising results and reduced the harm percentage to 0.001%～0.003%.
