Insecticide-treated mosquito nets may have given rise to resistant hybrid .


In Mali, insecticide-laced bed nets are being used to stave off mosquitoes and the malaria parasites they carry. The increased availability of the nets has been a great boon to public health in the region, but recently scientists noticed that some of the malaria-carrying Anopheles coluzzii were showing signs of resistance. The resistance genes appear to have been gleaned from a different mosquito, A. gambiae (above), in a hybridization of the two species,The Verge reports. The emergence of the hybrids appears to coincide with the introduction of the nets, and although it doesn’t necessarily prove a causal relationship, the study again highlights the challenges of racing against the evolutionary speed of infectious diseases and their vectors.
