摘　　要：以不同栽培模式下韭菜田内发生的韭菜迟眼蕈蚊为试材,采用系统调查的方法,研究了山东潍坊市昌乐县拱棚越冬韭菜和露地韭菜田内韭菜迟眼蕈蚊的发生动态。结果表明：拱棚韭菜扣膜期间,因5-10cm地温在9-14℃,温度较低,韭菜迟眼蕈蚊发育缓慢,只发生一代,扣棚后即是韭蛆的为害高峰,扣棚时间早晚与扣棚后幼虫发生为害高峰和成虫发生的高峰密切相关,扣棚早的幼虫为害盛期早,成虫发生早,反之则发生晚。对该虫采用＂治前控后＂的方法可有效控制其为害,即在冬季扣棚前幼虫期,使用高效、低毒的药剂进行灌根防治;棚内成虫发生期可使用黄色粘虫板诱杀成虫。露地栽培韭菜,春、秋两季是韭菜迟眼蕈蚊的为害盛期,应抓好春季的防治,在幼虫发生初期采用药液灌根处理或在成虫发生期地上喷雾防治。Taking Bradysia odoriphagaoccurred in the leek field under different cultivation patterns as test material,using the method of system investigation,the occurrence dynamics of Bradysia odoriphagaon leek in open-field-cultivation and winter facilities of Changle county in Shandong province were studied.The results showed that in winter facilities,the development of Bradysia odoriphagawas slow,only ageneration.Because the soil temperature of 5-10 cm solum was lower,only maintained at 9-14℃.HarmBradysia odoriphagareached peak during buckling canopy.Buckle canopy time and occurrence peak of adults and larvae were closely related.Buckle canopy time was early,larvae damage period and adults occurrence was early,otherwise,larvae and adults happened late.So the control of Bradysia odoriphagashall adopt＂treatment before and control after＂strategy,that was irrigation control larvae with highly effective,low toxic pesticides and yellow trap adults in the winter shelter.Spring and autumn was Bradysia odoriphagadamage stage in open-field-cultivation,we should combine larvae control with root-irrigation and adults control with spray in spring.
