| Summary: | The author who was appointed entomologist of the Biological Station in Perus, São Paulo, describes in this paper, the kind of work he has been doing there. He begins with a description of the organization of the Station and of the routine work as it was daily carried on there, by himself and his staff, during nearly 6 months. During the day as well as during the night, captures of jungle were made in the forest and the same was done by night, in the Station House chiefly when the athmosphere was damp, just before, during, or after a rain. There was also an intensive search for foci of mosquitoes' larves in the bromelias, in holes, in trees and in the soil. The larves found in these breeding places were brought to a larvarium established in the forest in a place close to the station where they were bred in holes of bambus which were very suitable for them. During daytime, only new hatched mosquitoes have been captured, but during the night it has been possible to catch, inside the Station house, many female mosquitoes, with developped eggs, so confirming Aragão's opinion, that mosquitoes biting during the day are always, newly hatched ones. Some species of Sabetini were captured only inside the Biological Station House, during the night. The habits of the following species were subjected to more accurate investigations. Aedes scapularis, Aedes leucocelaenus, Lutzia braziliae, Culex (Carolia) iridescens, Orthopodomyia albicosta, Goeldia palidiventer, Joblotia compressum, Wyeomyia longirostris, Sabetoides intermedius, Limatus durhami. The conditions of the temperature of the Station, did not permit the authour to obtain breedings of Aedes aegypti in the larvarium of the Station, even during he summer months. A great diminuitions of species of the jungle mosquitoes was observed, from January till June, that is, when temperature gets lower and lower. The author has made the interesting observation that some species of mosquitoes (Joblotia and Limatus), must take a meal of flowers or bee honey before they suck blood. ... |
