title: [Genetic distance of the malarial mosquitoes, Anopheles beklemishevi and Anopheles messeae (Diptera, Culiccidae), and their intraspecific polymorphism].
abstract: Allele frequencies at enzyme loci have been studied in Finnish populations of two species of the Anopheles maculipennis complex: A. beklemishevi and A. messeae. A. beklemishevi is spread over central and northern Finland, whereas A. messeae is found in southwestern and central Finland. The allele frequencies of these two species exhibit both similarities and differences. The results indicate that the two species do not interbreed in the nature. The allele frequencies at two loci--Hydroxybutyrate dehydrogenase (Hbdh) and Superoxide dismutase-2 (Su-2)--are almost totally different and adult individuals of the two species can be reliably diagnosed by these allelic differences. The genetic distance, D, between A. beklemishevi and A. messeae is 0.35. This value is compared with corresponding distances between other dipterans studied.
