One marker, Vgsc-1014S, was associated with insecticide resistance and P. falciparum infection in wild-caught mixed aged populations of A. gambiae s.s. thereby showing how resistance may directly impact transmission.
The angle at which the test is performed significantly affects the amount of time mosquitoes spend resting on the nets, and subsequently mortality.
While vector control on Bioko Island has succeeded in substantial reduction in overall vector biting rates, populations of An. coluzzii and An. melas persist.
We investigated how two environmental stresses (larviciding and nutritional stress) interact to affect Anopheles gambiae (previously An. gambiae S molecular form) life history traits and its susceptibility for field isolates of its natural malaria agent Plasmodium falciparum.
We considered these questions with the mosquito Anopheles gambiae by inoculating individuals simultaneously with one, two or three negatively charged Sephadex beads, and estimating the melanisation as the darkness of the bead (which ranges from about 0 for unmelanised beads to 100 for the most melanised beads of our experiment).
Y chromosomes control essential male functions in many species, including sex determination and fertility.
The study represents detailed vector characterization from an understudied area in West Africa with endemic malaria transmission.
These results support the hypothesis that the recent decline in An. gambiae was driven by the rollout of bed nets.
Here we develop a new approach that uses discriminant functions informed from inversion-specific expectations to classify loci that are under selection (or drift).
The low density of larval and adult stages of Anopheles mosquitoes, the absence of infected An. gambiae species and the low prevalence of Plasmodium in under 5-year-old children are important features that might facilitate malaria elimination in Conakry.
