“…Many of these mosquito species have been identified as common tree‐hole breeding mosquitoes and have been previously reported from the tree holes of these plants (Barraud, 1934; Chathuranga et al, 2017). Some of these mosquitoes preferentially feed on avian blood and recent studies that have been done in Sri Lanka, have reported the potential vector status of these mosquitoes in transmitting avian haemoparasites (Chathuranga et al, 2018, 2021). Aedes aegypti , Ae.…”

We investigated the physicochemical properties and the biotic interactions of breeding sites of tropical mosquito species. Field sampling was done in 12 study areas in Sri Lanka covering areas with secondary natural forests and human settlements. A total of 226 breeding sites were investigated to determine the biotic interactions and physiochemical properties of breeding water (pH, Conductivity, Dissolved Oxygen, Total Dissolved Solids and Temperature). A total of 80.5% of breeding sites from both habitats were positive for mosquito larvae of seven genera and 24 species. Orthopodomyia flavithorax (297) and Aedes albopictus (295) were dominated in tree holes of Alstonia macrophylla, Vateria copallifera and Artocarpus nobilis. Diversity indices showed that the diversity of mosquitoes is high in wet zone habitats of Sri Lanka compared to dry and intermediate zone habitats. Aedes albopictus coexisted with 11 different mosquito species while it avoided larvae of Culex fuscanus, Cx. uniformis and Tripteroides affinis. Strong positive associations were reported between Ae. albopictus and Ar. subalbatus while larvae of Or. flavithorax mosquitoes were not co‐occurred with the larvae of Ae. vittatus, Ae. aegypti, Cx. sitiens, Ar. subalbatus, Anopheles spp and Tr. affinis. The findings identified the breeding adaptability and tolerance to a wide range of physiochemical properties of tropical mosquito communities.

“…This is one of the most abundant groups of insects widespread throughout the country, and many act as vectors of life-threatening diseases such as dengue, chikungunya malaria, lymphatic filariasis and Japanese encephalitis (JE) (Herath et al, 1988;Peiris et al, 1993;Amerasinghe et al, 2002). Recent studies have reported the presence of ornithophilic and frog-biting mosquitoes, potentially vectors of emerging infectious diseases in humans and wildlife (Chathuranga et al, 2018;Chathuranga et al, 2021;de Silva et al, 2020). Accurate and precise identification of these mosquito species and siblings of species complexes is crucial for managing and controlling mosquito-borne diseases.…”

Disease-causing vector mosquitoes are prevailing throughout Sri Lanka, hence proper identification of these mosquitoes is crucial in implementing effective mosquito control approaches. The use of taxonomic keys based on external morphological characters of adults and larvae, is the common identification method. Due to the high diversity, abundance and presence of species complexes, proper identification using external morphology is challenging. The molecular approach is well-known but a costly method of mosquito identification in the country. This study was proposed to identify the variations in the male genital anatomy of mosquitoes from the Kandy District, Sri Lanka, to be used in mosquito identification. Monthly samplings were done in Peradeniya, Hantana, and Halgolla areas in Kandy, Sri Lanka. Male mosquitoes were identified using standard taxonomic keys. Male genitalia of these mosquito species were slide mounted. Photographs of the genital structures were taken. Male mosquitoes representing six genera (Aedes, Anopheles, Armigeres, Coquilletidia, Culex and Orthopodomyial) and 15 species were identified based on their external morphological features. Generic and species-specific features of the male genitalia of the studied mosquitoes were primarily seen in the gonocoxite, gonostylus, claspette, and phallosome. Speciesspecific features identified in the genitalia of mosquitoes are more reliable in accurately identifying male mosquitoes.
