Background: Indoor spraying of insecticides and the use of insecticide-treated bed nets are key strategies for national malaria vector control in the central highlands of Madagascar. During the year 2013, malaria outbreaks were reported by the National Malaria Control Programme in the highlands, including the district of Ankazobe.
Methods: Entomological trapping was carried out in April and May 2013 and in March 2014, using human landing catches, collection of mosquitoes resting in stables and in houses by oral aspirators, and Centers for Disease Control and Prevention light traps.
There were epidemic-epizootics of Rift Valley Fever (RVF) affecting humans and cattle in Madagascar in the district of Anjozorobe in 2008. Little is known about the role of Malagasy mosquitoes in the circulation of RVF virus. Therefore, we investigated the species diversity, dynamics and biology of potential RVF virus vectors in the rainforest, rainforest edge (village of Anorana), and savanna biotope (village of Antanifotsy) of this district between November 2008 and July 2010.

- Following RVF alerts in Madagascar, researchers collected and tested nearly 13,000 mosquitoes across several species to identify potential vectors for the RVF virus.
- RVFV was found in specific pools of Anopheles coustani, An. squamosus, and Culex antennatus mosquitoes, confirming their potential role in virus transmission.
- The genetic analysis showed that the detected strains were closely related to those affecting livestock and humans during recent outbreaks, highlighting the need for further studies on these mosquito species to enhance prevention efforts.
