Item Catalogue of the mosquitoes (Diptero:Culicidae) of Sri LankaAmerasinghe, F.P.Item Further observations on the mosquito fauna of Udawattakele forest, Sri Lanka(1984-85) Amerasinghe, F.P.; Munasinghe, N.B.A futher study of the mosquitoes at Udawattakele forest, Kandy was made during 1984-85, sampling the daytime resting, crepuscular-nocturnal human biting and light-trap attracted species, to suppliment information on the breeding and diurnal human biting species gatered during a previous study in 1980-81. Thirty species (7 genera) resting in the forest were collected using a battery powered suction sweeper, the dominant species being Culex psedovishnui. This species and Cx. nigropunctatus rested mainly on leaf litter on the forest or shrub/grass patches. Twenty five species (4 genera) were captured at human bait, with Armigeres subalbatus and Cx. pseudovishnui being the most prevalent. Biting rhythms associated with the evening crepaucular period were demonstrated in Aedes albopictus, Ar. subalbetus and Cx. psedovishoui, but not in Ae. chrysoscuta. Twenty five species (8 genera) were taken at CDC light traps with only Cx. pseudovishnui occurring in significant numbers. Overall, 61 species representing 11 genera have been recorded in Udawattakele Forest from all published sources. Species diversity indices as determined in the present study, however, were low and indicated the quantitative dominance of a few species in the forest in relation to the survey methods employedItem A guide to the identification of the anopheline mosquitoes (Diptera: culicidae) of Sri Lanka(1992) Amerasinghe, F.P.The taxonomy of Oriental and SE Asian anopheline mosquitoes has been extensively studied over the past two decades, resulting in greatly improved characterization of species and the definition of taxonomy features that are important in identification. However, published taxonomic keys for Sri Lankan anophelines have not been revised for over 50 years. This paper presents an illustrated key for the identification of larvae of 21 of the 22 currently recognized local anopheline species (the larval stage of the 22nd species is presently unknown), as a guide to workers engaged in malaria surveillance and control in Sri LankaItem A guide to the identification of the anopheline mosquitoes of Sri Lanka.111.
