MalariaWorldBiolarvicides, such as microbial formulations based on Bacillus thuringiensis and B. sphaericus, have been found to be highly effective against mosquito larvae and are currently employed as eco-friendly alternatives to synthetic chemical insecticides for vector control.

MalariaWorldTo investigate this species transition in more detail the present study aims to provide an update on the malaria vector composition in Bobo-Dioulasso, and also the plasmodium infection rates and susceptibility to insecticides of the local An. gambiae s.l. population.

MalariaWorldHere, we present a comparative analysis of the antimicrobial responses of two distantly related disease vectors: Aedes aegypti and Anopheles gambiae. Survival studies showed that Ae. aegypti are more proficient in surviving a bacterial infection than An. gambiae, and this correlates with Ae. aegypti’s superior ability to kill bacteria in their hemocoels.

MalariaWorldThe Anopheles gambiae immune response against Plasmodium falciparum, an etiological agent of human malaria, has been identified as a source of potential anti-Plasmodium genes and mechanisms to be exploited in efforts to control the malaria transmission cycle.

MalariaWorldThe study indicates that a major shift in An. gambiae s.l. sibling species composition has taken place in the study area in recent years. Combined with the earlier reported decline in overall malaria vector density, the study suggests that this decline has been most marked for An. gambiae s.s., and least for An. arabiensis, leading to current predominance of the latter.
