ABSTRACT
"Review of the genus Coquilletidia (Diptera : Culicidae) in Madagascar and description of the larva of Cq.grandidieri (Blanchard; 1905)"" : The genus Coquilletidia includes some of the mosquitoes involved in the transmission of numerous arbovirosis. Adults are locally abundant and very aggressive for men. In Madagascar; thus genus concerns 3 species among which 2 are endemic and had not been described at larval stage this far. The authors describe a single larva of Coquilletidia collected at Ankazobe in the Middle West of Madagascar; at an altitude of 1200 meters.The geographical distribution of Coquilletidia adults collected in various bio-climatic zones in Madagascar; combined with observed morphological characters; permit us to attribute this larva to Cq. grandidieri."

"Geographic Information System as a supplementary tool in malaria control in Madagascar"" : Following the severe malaria outbreak in the central highlands in Madagascarin 1986; a vector control program by use DDT pm 75 house-spraying has been implemented to operate in areas located at altitudes between 1000 and 1500 m. Early treatment with chloroquine has also been incorporated in the control program. To detect areas at particular high risk for malaria outbreak the Geographic Information System (GIS) has been applied and tested. The study has shown that the system can be used in malaria surveillance in order to identify areas in which an intense distribution of Anopheles funestus can be anticipated and; hence; targeted in spraying campaigns. The system may also be used to monitor changes in anti-malarial drug resistance; in addition; to control of other vector-born diseases."
