摘　　要：【目的】评价5%香芹酚水剂对韭菜迟眼蕈蚊(Bradysia odoripahaga)田间防效,以及对韭菜生长安全性影响。【方法】以0.3%苦参碱水剂作为对照药剂,通过灌根方式考察5%香芹酚水剂对韭菜迟眼蕈蚊防治效果,并通过增产率和品质感官评价评估其对韭菜生产安全性。【结果】田间试验表明,在韭菜迟眼蕈蚊发生初期施药1次,药后3~14 d,5%香芹酚水剂450.00 g(a.i.)/hm^(2)、600.00 g(a.i.)/hm^(2)处理对韭菜保株效果维持在49.10%~85.60%,药后21 d韭蛆虫口减退率和防治效果最高达76.26%和84.32%,对韭菜增产率达14.59%。【结论】5%香芹酚水剂对韭菜迟眼蕈蚊具有较好防治效果,对韭菜生长安全,可作为防治韭菜迟眼蕈蚊的绿色杀虫剂推广应用。[Objective]To evaluate the field control effect of 5%carvacrol AS on the chive maggot(Bradysia odoripahaga)and its impact on the growth safety of Chinese leek.[Methods]Using 0.3%matrine AS as control agent,the control effect of 5%carvacrol AS on B.odoripahaga was investigated through root irrigation,and its safety in Chinese leek production was evaluated through yield increase rate and sensory evaluation of quality.[Results]Field experiments showed that when applied once in the early stage of B.odoripahaga infestation,3-14 days after treatment,the protective effect on Chinese leek of 5%carvacrol AS at 450.00g(a.i.)/hm^(2),600.00g(a.i.)/hm^(2)was 49.10%-85.60%.After 21 d of treatment,the reduction rate and control effect of B.odoripahaga can reach 76.26%and 84.32%,and the yield increase rate of Chinese leek can reach 14.59%.[Conclusion]5%carvacrol AS has good control effect on B.odoripahaga,and is safe for leek growth.It can be promoted and applied as a green insecticide for the prevention and control of B.odoripahaga.
