Dr. Michelle Riehle and colleagues from the Pasteur Institute in Paris, France, recently have discovered a new type of mosquito in Burkina Faso. The team spent four years collecting mosquitoes from the ponds and puddles of populated villages. The new mosquito type, a subgroup of the species Anopheles gambiae, is raising concerns because it is a suitable vector for the transmission of malaria. Genetic analysis revealed many of the newly discovered type of mosquito not only have genetic backgrounds distant from any other A. gambiae previously recorded, but the type is especially vulnerable to the malaria parasite, making it a robust carrier of the disease. Scientists believe the type of mosquito may be a recently evolved subpopulation. Unlike other mosquito subpopulations commonly found indoors, this type prefers outdoor spaces, making it harder to control with nets and sprays.
