摘要
2023年9月—11月,长江上、中游柑橘产区出现果实蝇严重危害柑橘的新动态.桔小实蝇为主要害虫,其发生范围较往年急剧扩大;南亚果实蝇亦在部分区域出现,对柑橘果实造成危害,为该部分地区首次报道.田间调查显示,多数地区8月下旬果实蝇虫量明显上升,9月进入成虫盛期,10月初至上旬达到田间虫量高峰.其中,9月中下旬至10月初为果实蝇为害盛期,随后至10月末,为害程度明显下降.为应对这一新动态,湖北、四川、重庆的部分区域实施了诱蝇球与化学农药相结合的绿色防控措施,并进行了试验和示范.这一策略有效控制了果实蝇为害,为柑橘产业的可持续发展提供了实践参考.
From September to November 2023,there was a new trend of fruit flies severely damaging citrus in the upper and middle reaches of the Yangtze River.Most areas were affected by fruit flies,and the occurrence range rapidly expanded compared to previous years.In some areas,South Asian fruit flies have been found to cause damage to citrus fruits,which has not been reported in local history.According to the field investigations,the insect population in most areas increased significantly in late August,and reached peak of adult insects in September.The peak of insect population in the field was in early October.The peak period of damage is in mid to late September,with a peak in early October and a significant decrease of damage at end of October.In some areas of Hubei,Sichuan and Chongqing,a combined green prevention and control measure of fly traps and chemical pesticides was applied,and experiments and demonstrations were carried out.This measure effectively controlled the damage of fruit flies.
