Research Interests
Insecticide resistance (IR) is now widespread across many parts of the world which are reliant on public health insecticides to curb vector borne diseases. For example, over 80% of the reductions in malaria incidence between 2000 and 2015 were attributed to insecticide-based interventions, such as insecticide treated bed nets and indoor residual spraying. The use of insecticides leads to intensive selection pressure on the mosquito vectors, leading to high levels of IR.
IR in the major malaria vector species complex (Anopheles gambiae) is caused by five characterised resistance mechanisms (Figure 1) but is likely much more complex. For example, sub-lethal insecticide exposure, which occurs in areas with high levels of resistance, results in huge changes to the underlying transcriptome of Anopheles mosquitoes. Further, numerous lines of evidence indicate that this sub-lethal exposure results in large changes in underlying biology, such as changes in microbiome or redox state.
My research group investigates the impact of the insecticide resistance phenotype on Plasmodium development in vivo. Changes to mosquito biology and potential exposure to insecticidal compounds are likely to have huge impacts on the development of the malaria parasite within the mosquito vector (Figure 2). To address this, we combine bioinformatics and molecular biology to identify the pathways and genes important in these processes and characterise their effects on the two major phenotypes: vector competence and IR status.
