Abstract

Caves are one of the potential natural shelters of overwintering mosquitoes. The aim of this study was to explore the diversity, seasonal abundance, gender ratio and the vector status of mosquito imagoes collected from 19 caves if the Bakony-Balaton Region, Hungary, based on data of a monograph covering nearly 30 years of sample collections. Culex pipiens pipiens and Culiseta annulata were the most abundant trogloxene mosquitoes; Anopheles maculipennis, Anopheles messeae, Culex hortensis, Culex pipiens molestus and Culex territans were also collected in caves from July to April. The total mosquito number showed an approximately continuous increasing trend from July to November and a decreasing trend from December to April. Most of the mosquito specimens were collected in autumn and winter. Culex pipiens pipiens individuals were present in the caves from August to April. Male mosquitoes were collected only in the second half of the year, while female individuals – both in the first and the second half of the year. Both the relative abundance of males and females exhibited an increasing trend between August and November. The infected Culex pipiens pipiens mosquitoes, which start their diapause in the autumn, can be the potential vectors of the West Nile virus during the next year. It can be concluded that caves are important habitats of mosquitoes that are vectors of non-human pathogens in Hungary.
