In January 2013, a total of 9 suspected bubonic plague cases, 3 confirmed, were reported in Soavina, a rural area in the district of Ambatofinandrana, Madagascar, suggesting that these bites were the most common mode of Y. pestis transmission.
Ornithodoros Porcinus Ticks, Bushpigs, and African Swine Fever in Madagascar
Ticks of the Ornithodoros moubata group, considered to be O. porcinus Walton, 1962 were formerly known to occur in western Madagascar, but seem to have disappeared from that region, however, three new sites where they occur were found in the humid and cool central highlands of Anatananarivo province.
Detection, isolation, and genetic characterization of Rift Valley fever virus from Anopheles (Anopheles) coustani, Anopheles (Anopheles) squamosus, and Culex (Culex) antennatus of the Haute Matsiatra…

Following veterinary alerts of Rift Valley fever (RVF) in the districts of Fianarantsoa I and II in November 2008 and in the district of Ambalavao in April 2009, entomological and virological…

Depending on the length of contact between the adult flea and its host, the fleas are classified into holometabolous (complete transformation duringmetamorphosis) wingless insects, adapted to jump, and adults of both sexes are hematophagous (blood-feeding).
Outbreak of Dengue and Chikungunya Fevers, Toamasina, Madagascar, 2006
An outbreak of dengue-like syndrome occurred in Toamasina from January through March 2006. Dengue type l or chikungunya viruses were detected in 38 of 55 patients sampled. Aedes albopictus was the…

Rats' movements according to the season were likely directed by the availability of food, and important indicators of vector abundance and plague transmission were higher during the high plague transmission season.
Entomological and parasitological impacts of indoor residual spraying with DDT, alphacypermethrin and deltamethrin in the western foothill area of Madagascar
The use of IRS with DDT and pyrethroid greatly decreased the vector-human contact, with an associated decrease of the plasmodial index, however malaria transmission did not reach zero, probably due to the exophilic host-seeking and resting behaviours of the malaria vectors.
Geographical and environmental approaches to urban malaria in Antananarivo (Madagascar)
Geographical and environmental factors did not show direct relationship with malaria incidence but they seem ensuring suitability of vector development, and imported malaria case is suggestive to sustain the pocket transmission in Antananarivo.

The risk map obtained can be used to identify priority zones for the management of resources, and also help avoid systematic and generalised spraying throughout the highlands: such spraying is particularly difficult and expensive.
Anopheles mosquito surveillance in Madagascar reveals multiple blood feeding behavior and Plasmodium infection

The application of tools that advance understanding of diversity, host choice, and Plasmodium infection in the Anopheline mosquitoes of the Western Highland Fringe of Madagascar are described, suggesting this complex feeding behavior could enhance the role of multiple Anophelines species in malaria transmission.
