Diversity and seasonal dynamics of invasive mosquito species in Brod-Posavina County, Croatia

Monitoring of invasive mosquito species in Brod- Posavina County in Croatia (as a part of National monitoring of invasive mosquito species) was conducted during seasons 2019 and 2020 from May to November. Oviposition traps were installed at 24 locations: 8 ovitraps were placed in private backyards, 4 in specialised tire fitting shops, 2 in cemeteries, 4 in school and hospital backyards and others at landfill site, border crossing etc. The purpose of the study was to determine invasive mosquito species and to examine the environmental effect on their preference for different oviposition site. During 2019, a total of 57210 eggs were recorded, while in 2020 only 29184. The progress of mosquito developmental stages had been monitored and recorded in laboratory every week. In 2019, a total of 1391 adult mosquitoes were sampled, 98% of which belonged to Aedes (Stegomyia) albopictus (Skuse, 1895). In 2020, 427 adult mosquitoes were developed and only 19 belonged to Aedes japonicus (Theobald, 1901). Both mosquito species were recorded at 2 locations in 2019 and at 4 locations in 2020. A significant dominance of Aedes albopictus was recorded for both years, probably due to the most favourable oviposition place and potentially increasing artificial containers as breeding sites in the vicinity.
