摘　　要：随着德州市韭菜栽培面积的逐年扩大,种植韭菜的经济附加值较高,但是连年栽培导致韭菜迟眼蕈蚊危害进一步加重。由于大多数种植户的防治工作未得到科学指导,加之市场需求旺盛,导致韭菜迟眼蕈蚊的防治用药非常混乱,很多种植户使用有机磷杀虫剂灌根,导致韭菜农药残留偏高,严重危害到广大人民群众的健康。通过分布调查和田间药效试验分析,得出1年内韭菜迟眼蕈蚊有2个成虫危害高峰期,分别为春季和秋季。并采取不同生物源药剂与物理防治相结合的方法进行治理,结果表明,采用糖醋液田间诱杀成虫和生物源杀虫剂灌根相结合的控制方法,不但可以实现韭菜高产、增加农户经济收入,而且对韭菜迟眼蕈蚊的控制效果较好,韭菜迟眼蕈蚊的死亡率95%以上,其中甲维·灭幼脲生物药剂防治效果最好且持效期最长。At present,the area of Leek cultivation in Dezhou is increasing year by year,and the economic added value of Leek cultivation is high,however,the damage of Bradysia odoriphaga caused by continuous cultivation has been further aggravated.At present,most farmers have no scientific guidance in their control work.In addition,the market demand has led to a great confusion in the control of Bradysia odoriphaga many farmers use organophosphorus pesticides to irrigate the roots,resulting in high pesticide residues leek,seriously endangering the lives of the People's health and safety.Based on the investigation of distribution and the analysis of field efficacy,two peaks of adult damage of Bradysia odoriphaga were found in spring and autumn.In this study,different biological pesticides were used in combination with physical control.The results showed that sweet and sour liquid was used to trap and kill adult insects in the field and biological pesticides were used to irrigate the roots,it can not only increase the economic income of the farmers but also control the Bradysia odoriphaga.The mortality rate of Bradysia odoriphaga.is over 95%.The biocontrol effect of Diflubenzuron was the best and its duration was the longest.
