Pwani Molecular Form Latest News
A new mosquito species, provisionally named the “Pwani molecular form”, has been discovered in the coastal regions of Tanzania and Kenya.
About Pwani Molecular Form
- The species belongs to the Anopheles gambiae complex, a group comprising some of the world’s most potent malaria vectors.
- The Pwani mosquito shows clear genetic divergence from other members of the Anopheles gambiae complex, indicating it could have distinct ecological or behavioural adaptations.
- Genetic sequencing confirms that this species is geographically restricted to coastal East Africa, especially Tanzania and Kenya.
- Unlike known malaria vectors in the region, this mosquito lacks the usual genetic markers for insecticide resistance, indicating a unique resistance mechanism or greater susceptibility to existing insecticides.
- This creates serious implications for current malaria control strategies, which depend heavily on chemical insecticides, including bed nets and indoor residual spraying.
