A brief survey of the mosquitoes of South Sulawesi, Indonesia, with special reference to the identity of Anopheles barbirostris (Diptera: Culicidae) from the Margolembo area.

In May 1972, a brief survey of mosquitoes was carried out in the Margolembo area and several other localities in South SuIawesi, Indonesia. A total of 37 species of mosquitoes was collected which include 10 species of An&&s, 3 species of &&m&a, 7 species of A.&s, 15 species of Culex and 1 species each of Malaya and Uranotamia. Six of 37 species collected have not been previously recorded from Sulawesi. Dissection of 31 anophelina and I6 culicines did not reveal any malarial or filarial infection_ The morphological characters of the larvae of Culex (~~~ceraamzia) sp. and C&x psdtihnui are briefly described. The identity of Anopheles barbirostris from South Sulawesi is discuss& and a list of 132 taxa of mosquitoes hitherto recorded from Sulawesi and adjacent islands is presented. The prevalence of malaria and filariasis in transmigration villages of Margolembo, Luwu Regency, South Sulawesi Province, Indonesia, has been investigated and the results published by Cross et al. (1972) and Partono et al. (1972, 1973). In the same area, a search for mosquito vectors conducted by Partono et al. (1972) revealed the presence of 5 species Of Culex, 1 species of Mansonia, and 2 . species of [email protected] ; dissection of these mosquitoes revealed developing filarial larvae only in An. barbiroslrisThe object of the present study was to obtain immature stages of An. barbirostris for verification of iti identity and to study other mosquito fauna. The villages included in the survey were Kalaena (village I), Sindu Binagun (village II) and Margolembo (village 111) (FIG. 1). The mean annual temperature in the area is 27 “C. The rainy season is from October through April, and the relative ‘ This study was supported by funds provided by the Ministry of Health, Indonesia, and the Naval Medical Research and Development Command, Navy Department, for Work Unit No. MROQI.09.01-@)83B OGI.

According to Cross et al. (1972), malaria prevalence in the 3 villages in March 1970 was 15.7%, 32.6% and 11.2%, respectively. Partono et al. (1972) reported Malayan filariasis in the same villages, with microfilarial rates of 33.0%, 0.6% and 32.5x, respectively. A filariasis control program, using diethylcarbamazine, was introduced in the 1st and 3rd villages in March 1971; however, control measures were not undertaken in the 2nd village prior to May 1972. According to Partono et al. (1973), malaria and filariasis prevalence rates in the 2nd village in May 1972 were 23.2% and 3.1%, respec-
