I am a PhD student investigating parasite evolution in response to vector control programmes.
Many insect vector populations are evolving mechanisms to evade current vector control programmes, reducing the efficacy of these methods. Because of this, the evolutionary response of vectors is being closely monitored, but the potential response of parasites has been largely overlooked. I am interested in how changes to the within-vector environment caused by vector control affects parasite development, and whether parasites can adapt in order to maximise their survival and transmission.
Understanding the evolutionary potential of parasites will help to inform monitoring strategies for current control programmes, and provide insight into future strategies that can withstand unfavourable parasite evolution.

We tested a non-destructive method to detect sporozoites from individual infected mosquitoes on sugar-feeding substrates. Detection rate was surprisingly low, and investigations of the biological causes underlying this is needed to maximise the utility of using non-destructive assays to quantify sporozoite dynamics

This review highlights how vector control tools such as insecticides have altered mosquito vectors and consequently parasite ecology, and discusses how parasites might be able to respond. Understanding parasite responses is important because they could undermine gains made towards malaria elimination and may have knock-on consequences for parasite-host interactions.
