Functional characterization of an allatotropin receptor expressed in the corpora allata of mosquitoes

► We characterized an allatotropin receptor expressed in the mosquito Aedes aegypti. ► The receptor is stimulated by mosquito allatotropin in the low nanomolar concentration range. ► The receptor is expressed in the corpora allata (CA), not in the corpora cardiaca. ► The pattern of changes of receptor mRNA in the CA resembles the changes in JH biosynthesis.
