title: [Distribution of natural parasites--fungi and microsporidia--in a  population of malarial mosquito larva (Diptera: Culicidae) before and after infection by the entomopathogenic bacteria Bacillus thuringiensis israelensis].
abstract: The distribution specificity of fungi and microsporidies in natural population of Anopheles messeae Fall. and A. beklemishevi Stegny et Kab. and those which survived after treatment them by Bacillus thuringiensis israelensis (Bti) were observed. Parasitic fungus nonselectively affected individuals of both species and all inversion genotypes of A. messeae. Microsporidia Parathelohania messeae affected males and it has not species and genotypic specificity. The 4-th instar larvae of both species infected by parasitic fungus after treatment them by Bti did not survive. The level of microsporidian infection of A. messeae and A. beklemishevi after Bti treatment was reduced from 1.1 +/- 0.5 to 0.5 +/- 0.3% and from 1.3 +/- 1.3 to 0.7 +/- 0.5% accordingly. A. beklemishevi was registered as Parathelohania messeae host for the first time. The harmonious relationships between malaria mosquitoes and their parasites in natural populations may be destructed by the Bti treatments.
