摘　　要：田间试验结果表明 ,阿维菌素对美洲斑潜Liriomyzasativae蝇幼虫防效较好 ,优于伊维菌素对美洲斑潜蝇的防效 ,可较好地控制美洲斑潜蝇幼虫的危害 ,而Btg,Bti,Bs不宜单独用于防治美洲斑潜蝇幼虫。阿维菌素用量为 0 2 7,0 3 6,0 45g (a .i.) 667m2 时 ,对美洲斑潜蝇幼虫防效第 7d校正防效为 65 %左右 ,施药后第 1 1d校正防效为 85 48%～ 99 0 5 % ,施药后第 1 5d校正防效为 90 94%～ 99 89%。伊维菌素 0 5g (a .i.) 667m2 施药后第 3 ,7,1 1d校正防效分别为 61 67% ,90 5 3 % ,90 93 % ,伊维菌素 0 2 5g(a i ) 667m2 相应防效为 5 7.71 % ,84 68% ,85 83 %。Btg ,Bti,Bs施药后第 3 ,7,1 1d校正防效为 3 3 88%～ 5 5 5 4%。Field trials indicated that abamectin was effective in the control of Liriomyza sativae. Abamectin was more effective to L. sativae than ivermectin. Three bacillus products [Bacillus thuringiensis var. galleriae (Btv)],[ B.thuringiensis var. israelensis (Bti)] and B. sphaericcus (Bs) wasn't suitable for the control of L. sativae . Mortality rates after application of abamectin at 0 27, 0 36 and 0 45 g (a.i.)/667 m 2 were around 65% after 7 d, 85 48%～99 05% after 11 d and 90 94%～99 89% after 15 d. Corresponding mortality rates for ivermectin 0 5 g (a.i.)/667 m 2 were 61 67%, 90 53% and 90 93%. When applied at a reduced concentration of 0 25 g (a.i.)/667 m 2 corresponding mortality rates for ivermectin were 57 71%, 84 68% and 85 83% respectively. Corresponding rates for Btg, Bti, Bs. were 38 32%～50 27%, 33 88%～55 54%, and 42 55% ～ 52 30% repectively.
