[The effect of infection by the entomopathogenic bacterium Bacillus thuringiensis on the spread of microsporidia in an inversion-polymorphic population of the malarial mosquito Anopheles messeae (Diptera: Culicidae)].

A specificity of distribution of the microsporidia Parathelohania sp. in a natural population of Anopheles messeae and in those, which survived after the treatment by subspecies Bacillus thuringiensis fukuokaensis, B. t. darmstadiensis and B. t. kyushuensis (pathotype B), were observed. The microsporidia Parathelohania sp. affected males and it did not show a genotypic specificity in control, but it had a genotypic specificity after the B. thuringiensis subspecies treatment.
