The impact of insecticide resistance on the fitness of Anopheles coluzzii mosquitoes

The impact of insecticide resistance on the fitness of Anopheles coluzzil mosquitoes

As part of the ILAS Fellowship Scheme, earlier this year, the Institute was delighted to welcome Dr Seynabou Sougoufara from the Vecteurs-InfectionsTropicales et Mediteranneenes (VITRO), Dakar, Senegal. During her time here she was hosted by her academic partner Professor Fredric Tripet from the Centre for Applied Entomology and Parasitology (CAEP) in the School of Life Sciences.

Dr Sougoufara‘s doctorate from the University Cheikh Anta Diop Dakar in 2015 involved work on key features of the Anopheles mosquitoes (vectors) that transmit malaria between people in a Senegalese village setting. In her time at Keele she worked with Professor Tripet and colleagues in CAEP on their joint project; The impact of insecticide resistance on the fitness of Anopheles coluzzil mosquitoes, focusing on assessing the insecticide resistance and the mating behaviour of a new strain of Anopheles coluzzii mosquitoes. 

Malaria is a major public health problem in sub-Sahara African countries (WHO, 2017). Control measures against this disease are mainly based on anti-vectorial programmes that use insecticide-treated bed nets and indoor residual spraying. However, resistance to the main chemical classes of insecticides used in public health is growing. For this reason, studies evaluating the fitness of resistance in mosquito populations are very important in informing the design and implementation of effective pesticide-resistance management schemes.

The research project brought together Professor Tripet’s extensive experience in molecular ecology, population genetics and behaviour and Seynabou’s experiences in research field conditions studying the composition and the diversity and dynamics of malaria vectors.
