Both sexes of the stable fly, Stomoxys calcitrans L. (Diptera: Muscidae), have receptors on their mouthparts that mediate blood feeding. The potency ranking of the adenine nucleotides (ATP > ADP > AMP > adenosine) in eliciting feeding and suppressing the NaCl‐sensitive cell may indicate the involvement of a P 2 ‐type receptor. This is supported by the lack of effect on feeding by methyl xanthines. Feeding‐related behavioural and electrophysiological results demonstrate that the potency of CH 3 ‐S‐ATP is not greater than that of ATP. These ATP‐mediated responses are antagonized by ANAPP 3 . Results support the conclusion that the putative ‘ATP receptor’ involved in stable fly phagostimulation resembles the P 2x purinoceptor of vertebrates.
