中文摘要：40 mg/kg多杀菌素(spinosad)或1 000、3 000 mg/kg荧光桃红B(Phloxine-B)均不影响3日龄橘小实蝇雌Bactrocera dorsalis (Hendel)、雄虫对蔗糖的取食量（P>0.05）；与蒸馏水对照和马拉硫磷对照相比，40 mg/kg多杀菌素或1 000 mg/kg荧光桃红B对雌、雄虫吐食率也无显著影响（P>0.05），但3 000 mg/kg荧光桃红B对雌、雄虫吐食率有极显著影响（P<0.01）。40 mg/kg多杀菌素或1 000 mg/kg荧光桃红B对6日龄橘小实蝇雌、雄虫对蔗糖的取食量与蒸馏水对照无差异（P>0.05）；3 000 mg/kg荧光桃红B对雌虫的取食量与蒸馏水对照有显著差异（P<0.05），与马拉硫磷对照无差异（P>0.05），对雄虫的取食量与蒸馏水对照无显著差异（P>0.05），与马拉硫磷对照有显著差异（P<0.05）。与蒸馏水、马拉硫磷相对照，40 mg/kg多杀菌素或1 000 mg/kg荧光桃红B对雌、雄虫的吐食率均无显著影响（P>0.05），而3 000 mg/kg的荧光桃红B对雌、雄虫的吐食率均有极显著影响（P<0.01）。
英文摘要：The results showed that neither 40 mg/kg spinosad nor 1 000 and 3 000 mg/kg Phloxine-B influenced sugar ingestion for 3-d-old oriental fruit flies. With distilled water control and malathion as control, 40 mg/kg spinosad and 1 000 mg/kg Phloxine-B did not affect the regurgitation ratio of both females and males significantly, whereas 3 000 mg/kg Phloxine-B affected it significantly. When treated with 40 mg/kg spinosad or 1 000 mg/kg Phloxine-B, there was no difference in sugar ingestion for 6-d-old oriental fruit flies compared with distilled water. The difference between treated with 3 000 mg/kg Phloxine-B and distilled water was significant for females and not significant for males, but no difference compared with malathion. Neither 40 mg/kg spinosad nor 1 000 mg/kg Phloxine-B affect the regurgitation ratio significantly, but 3 000 mg/kg Phloxine-B had significant effect on both females and males.
