摘　　要：为进一步筛选适合田间施用蛋白诱剂条件下的实蝇杀虫剂种类和用量,室内测定了多杀菌素和荧光桃红B分别与阮酵母水解蛋白组配后对橘小实蝇自由取食的胃毒毒性.结果表明,多杀菌素和荧光桃红B均适合与水解蛋白组配防治橘小实蝇.多杀菌素和荧光桃红B对橘小实蝇雌、雄成虫在5h内的致死中浓度分别为12.7570、13.9535和779.9378、826.6259mg/kg,16和100mg/kg多杀菌素对橘小实蝇雌、雄成虫的致死中时间分别为4.1904、4.9730h和2.4877、2.6755h,630和1000mg/kg荧光桃红B对橘小实蝇雌、雄成虫的致死中时间分别为5.3507、4.9462h和4.7650、4.5715h.In order to choose the best insecticide for fruit fly protein hydrolysate baits in field,laboratory tests were taken to assess the stomach toxicity of spinosad and phloxine B with torula yeast protein hydrolysate on oriental fruit flies,Bactrocera dorsalis （Hendel） female and male adults.Median lethal concentration values of spinosad and phloxine B on B.dorsalis male and female adults at 5 h were 12.757 0 mg/kg,13.953 5 mg/kg;779.937 8 mg/kg,826.625 9 mg/kg respectively.Median lethal time of spinosad was 4.190 4 h（females） and 4.973 0 h（males） at 16 mg/kg and 100 mg/kg;The median lethal time of spinosad was 2.487 7 h（females） and 2.675 5 h（males）.For phloxine B,at 630 mg/kg the median lethal time was 5.350 7 h（females） and 4.946 2 h（males）,and at 1,000 mg/kg the median lethal time was 4.765 0 h（females） and 4.571 5 h（males）.
