The transcriptome of anal papillae of Aedes aegypti reveals their importance in xenobiotic detoxification and adds significant knowledge on ion, water and ammonia transport mechanisms

•Identified ion transporter genes permit development of a more comprehensive model.•Results suggest anal papillae are major sites of ammonia detoxification.•Results suggest anal papillae are major sites of xenobiotic detoxification.•Aquaporin AaAQP2 expression is likely important during abrupt brackish water exposure.
