摘　　要：20世纪90年代中期以来,南美斑潜蝇已成为西南烟区为害烟草的新害虫,主要为害烟苗和烟草大田生长前期的脚叶。在云南省昭通市烤烟生长期,南美斑潜蝇可完成5～6代,完成1代需要18～34d。该蝇系多食性害虫,对寄主作物有明显的选择性,对烟草有较强的适应性。烟草苗期为防治重点时期,2.5%"功夫"乳油2000倍液喷施,施药后3d和9d,防治效果分别为53%和77%;50%"蝇蛆净"水溶性粉剂1000倍液喷施,施药后3d和9d,防治效果分别为59%和81%。Liriomyza huidobrensis (Blanchard) is a new pest damaging tobacco in southwest of China, it mainly fed on seedlings and foot-leaves in early field stage. It completed 5-6 generations during the growth of flue-cured tobacco in Zhaotong of Yunnan province, one generation spanned 18-34days. The pest is polyphagous, has obvious selectivity for hosts and good adaptability to tobacco. Control during seedling stage is of vital importance. 3 days or 9 days after spraying,the control effects of 2.5% kungfu EC at a dilution of 2000 are 53% and 77%,respectively,and those of 50% Neprex at a dilution of 1000 are 59% and 81%,respectively.
