Abstract

Females of four common Culex (Culex) species from Florida were analyzed for isoenzymes using polyacryamide gel electrophoresis. Ten enzymes that yielded 11 putative loci were studied. Most of the loci showed diagnostic characteristics in the four species, but four of the loci (glycerol-3-phosphate dehydrogenase [Gpd-2], hexokinase [Hk], isocitrate dehydrogenase [Idh-1], and malate dehydrogenase [Mdh]) could be used in sequence to identify the four Culex species. Culex salinarius and Cx. p. quinquefasciatus could be separated from Cx. restuans andCx. nigripalpus by Mdh locus. Culex salinarius could be distinguished from Cx. p. quinquefasciatus by Hk locus and Cx. nigripalpus could be distinguished from Cx. restuans, by Idh-1 and/or Gpd-2 loci. Randomly combined specimens of these four Culex species were identified accurately by using these enzyme loci.
