ALTERNATIVE WAYS OF NUTRITION OF MALARIAL MOSQUITOES’ LARVAE (DIPTERA, CULICIDAE) AS IMPORTANT COMPONENTS OF THEIR ADAPTIVE COMPLEXES

Perevozkin Valeriy Petrovich, Galkin Vitaliy Sergeyevich

Information About Author:

Behavioral features of malarial mosquitos’ larvae Anopheles atroparvus (Diptera, Culicidae) are studied and connected with additional ways of meal reception – a substratum scraping and cannibalism. Results of experiments demonstrate that larvae of young and advanced stages Anopheles have various trophic and spatial niches in biotopes. Fall of food concurrence among stages and pressure of cannibalism on larvae of younger stages are reached. At the same time, individuals of advanced stages A. аtroparvus actively dive on depth of ten centimeters in search of forage, being switched over to alternative type of a food – the scraping.
