[Various aspects of the ecology of mosquitoes (Diptera, Culicidae) from a plains area (Calabria Farms) in Jacarepagua, Rio de Janeiro. V. Breeding grounds].

Results are presented of observations on the breeding places of mosquitoes, carried out in a coastal lowland farm--Granjas Calábria, in Jacarepguá, city of Rio de Janeiro, Brazil. The majority of species preferred breeding places on the ground, chiefly the natural ones, but also developed in those originated from human activities. Cx. saltanensis and the species belonging to the Aedini tribe, such as Ae. scapularis, Ae. taeniorhynchus, Ps. ciliata, Ps. confinnis and Ps. pseudomelanota were more abundant in temporary breeding places, while Ma. titillans, Cx. amazonensis, Cx. chidesteri, Cx. bidens, Cx. declarator, Cx. nigripalpus and Cx. plectoporpe occurred usually in the permanent ones. Some species were collected in natural recipients: Cx. ocellatus, the Cx. (Microculex), Ph. davisi, Ph. deanei and Wy. forcipenis, in bromeliads; Ae. terrens, Cx. imitator and Cx. gairus, in tree-holes; and Wy. leucostigma, in the submerged Typha dominguensis leaf axils. Cx. gairus was found for the first time breeding in artificial containers, which were also preferred by Cx. corniger, Cx. quinquefasciatus and Li. durhami.
