Louisa Messenger (Environmental and Occupational Health) co-published a paper on "Insecticide Resistance in Aedes aegypti Mosquitoes: Possible Detection of kdr F1534C, S989P, and V1016G Triple Mutation in Benin, West Africa" in the journal Insects.

The effectiveness of chemical control of Aedes (Ae.) aegypti is threatened by the increasing frequency of insecticide resistance. This study aimed to determine, in two cities of Benin, the insecticide resistance profiles of Ae. aegypti, the presence of detoxification enzymes, and the frequency of kdr mutations.
