Abstract

This paper follows the study from 2013 focused on the molecular screening of mosquitoes as vectors of Dirofilaria spp. which provided the information on Aedes vexans as a potential vector of Dirofilaria repens in Slovakia. Current entomological and molecular research indicates that Ae. vexans can participate also in the transmission of Dirofilaria immitis within the region. Using the standard PCR method, we examined 10,500 mosquitoes (Ae. vexans, Ae. rossicus, Anopheles maculipennis s.l., Ochlerotatus sticticus, Ochlerotatus cantans, Ochlerotatus caspius, Culex pipiens/Culex torrentium, Coquillettidia richiardii), collected using CO2-baited traps at six locations in the Eastern Slovakia. Out of 105 pools, 6 pools of mosquitoes Ae. vexans were positive for D. repens DNA (minimum infective rate in Ae. vexas was 6:6.900, i.e. 0.8 per 1.000 mosquitoes), within which 4 were concurrently positive for D. immitis (minimum infective rate in Ae. vexans was 4:6.900 i.e. 0.5 per 1.000 mosquitoes).
