摘要: 目的?摇比较PCR和同工酶两种鉴别微小按蚊A、C亲缘种的方法。 方法 将现场采集后经形态初步鉴定为微小按蚊的样本,经PCR产物酶切片段长度多态性分析(PCR-RFLP)与乌头按蚊和杰普尔按蚊区分,等位基因特异扩增法(PCR-ASA)进一步鉴别微小按蚊A和C。再将用此方法鉴别后的微小按蚊羽化24 h内单只虫体样本,采用垂直平板聚丙烯酰胺凝胶电泳,加以辨别区分。 结果 经测序验证,PCR方法可以简单明确地将微小按蚊A、C加以鉴别。几种用于鉴别的同工酶中,只有酯酶(EST)同工酶对微小按蚊A、C具鉴别意义。 结论 对于微小按蚊A、C的鉴别,PCR方法明显优于同工酶方法。

Abstract: Objective To compare the PCR and isoenzyme methods in identification of Anopheles minimus A and C. Methods Samples of An. minimus collected in the field were identified from An. aconitus and An. jeyporiensis by PCR-RFLP after morphological examination, then classified by PCR-ASA. The mosquitoes identified by this method were further analyzed for isoenzyme to observe the difference, which was previously used as a technique to classify An. minimus A and C. Results PCR method can differentiate An.minimus A and C simply and quickly. For Isoenzyme method, only EST allozyme pattern displayed difference. Conclusion PCR method is better than isoenzyme analysis in differentiating An. minimus A and C.
