Abstract The probabilistic approach was applied to morphometric identification of Culex pipiens pipiens / torrentium mosquito females collected in the Sablino caves (Leningrad Province of Russia). The distances between landmarks of the radial wing veins r(2+3) and r3 were measured, and the frequency distribution of the r(2+3) / r3 wing vein index was analyzed. The obtained distribution had two maxima

Abstract The role of fleas in the manifestations of plague epizootics in the natural plague foci in Russia and adjacent states is discussed. The specific conditions of pathogen transmission in each focus are determined by the vital activities of several species of fleas that are parasites of the main plague carrier. These fleas have the nidicolous type of parasitism, facilitating wide spread of the

Abstract Catalase is an antioxidant enzyme, which is important for lifespan extension and stress resistance during diapause in overwintering mosquitoes. Based on the preliminary observations on abundancies of Culiseta annulata (Schrank) and species of the genus Culex, overwintering in the Sablino Caves (Northwestern Russia), it was hypothesized that catalase activity in hibernating females might vary
