ABSTRACT
Isozyme banding patterns of the recently recognized autogenous stenogamous and anautogenous eurygamous sexually isolated Aedes caspius forms were investigated using horizontal starch gel electrophoresis of 5 enzymes. The esterase assay clearly separated the 2 forms, a faster band being characteristic of autogenous individuals. Other tested enzymes were encoded by 5 loci that were highly polymorphic. The "malic" enzyme locus was unambiguously diagnostic, specific, non-overlapping alleles at that locus were revealed in each form. Other enzyme loci screened exhibited at least 2 alleles common to both forms, allelic frequency differences at these loci could not separate the 2 forms except at the cathodal MDH-1 locus [malate dehydrogenase assay]. Probability of correct diagnosis at the MDH-1 locus was as high as 93% so that it may be used as a confirmatory test
