چکیده
??r hours. The subject was Pursuecl J""^ Wlth the object of arriving at some effectrve, convenient and cheap method of dea & le millpond problem. As stated in the last paper, since the introduction of electric drive in the Bombay mills, these large collections of water are 110 longer in use and do not get heated up as they used to when the mills were working with steam power. As the cost of filling up the tanks is considered prohibitive, and as provision has to be made for a ready supply of water for fire purposes, these tanks or ponds or mill-lodges are at present " necessary evils," and add greatly to the enormous numbers of breeding places that already exist in the island or form during the monsoon and malaria season.

Identifying malaria vector breeding habitats with remote sensing data and terrain-based landscape indices in Zambia
BACKGROUND Malaria, caused by the parasite Plasmodium falciparum, is a significant source of morbidity and mortality in southern Zambia. In the Mapanza Chiefdom, where transmission is seasonal, Anopheles arabiensis is the dominant malaria vector. The ability to predict larval habitats can help focus control measures. METHODS A survey was conducted in March-April 2007, at the end of the rainy ...
متن کاملMolecular entomology and prospects for malaria control.
During the past decade, the techniques of molecular and cell biology have been embraced by many scientists doing research on anopheline vectors of malaria parasites. Some of the most important research advances in molecular entomology have concerned the development of sophisticated molecular tools for procedures such as genetic and physical mapping and germ line transformation. Major advances h...

Surveys for anopheline mosquitoes were conducted throughout the mainland of Papua New Guinea from 1992 to 1998 with the aim of mapping the distribution of the anopheline fauna. Larval collections, adult trap, and human landing collections indicated the presence of seven species (other than those belonging to the Anopheles punctulatus group); these were An. bancroftii, An. annulipes, An, karwari...

BACKGROUND & OBJECTIVES Despite the increasing number of reported autochthonous malaria cases in Nouakchott and the identification of Anopheles arabiensis as the major malaria vector in this Saharan city, anopheline larval habitats have never been identified so far. The objective of this study was to identify and characterize anopheline larval habitats in Nouakchott. METHODS During September ...
