title: [Restriction fragment length differences (RFLDs) of genomic DNA from different geographical strains of Anopheles sinensis and Anopheles anthropophagus].
abstract: Total DNA was extracted from three geographical strains of Anopheles sinensis and two geographical strains of Anopheles anthropophagus and digested respectively with three restriction endonucleases (Bgl II, Hae III and Pst I). The restriction fragment length differences (RFLDs) of repetitive DNA detected after agarose gel electrophoretic separation and ethidium bromide staining were compared among the above-mentioned geographical strains of both An. sinensis and An. anthropohagus. The results indicated that the band patterns are species- specific and strain-specific, their main bands being similar while their minor bands being distinctly different. Pst I digestion produced unique fragments for three geographical strains of An. sinensis while Bgl II digestion produced unique fragments for two geographical strains of An. anthropophagus. In view of the variation in repetitive DNA of different geographical strains of both An. sinensis and An. anthropophagus presented, the RFLDs could be used as a means to distinguish various closely related geographical strains of anopheline mosquitoes.
