分析抗性家蝇蛹期多肽，以了解蛋白质变化情况。方法：对家蝇的抗性株、对照株和敏感株蛹体内的多肽进行了聚丙烯酸胺凝胶电泳分析。结果：抗性株具有一特异的多肽点，且有3个多肽点在量上明显多于对照株。结论：杀虫剂的作用可使抗性家蝇体内的蛋白在质和量上发生改变。
Analysis of the Musca domestica pupa peptide to understand protein changes. Methods: Polyacrylamide gel electrophoresis analysis was performed on the pupae of housefly resistant, control and sensitive strains. Results: The resistant plants had a specific polypeptide point, and there were more spots in the three peptides than the control plants. Conclusion: The effect of insecticide can change the quality and quantity of protein in resistant housefly.
