. The potencies of seventeen analogues of ATP as gorging inducers for Glossina palpalis palpalis were evaluated. The ranking for effective dose that induced half the flies to gorge (ED 50 ) was: A tetra P 5 ATP=2'd ATP ADP=2'd ADP > AMP‐PNP > 3'd ATP 2'3′dd ATP > AMP‐PCP > adenosine 5′ triphosphate 2′,3'dialdehyde AMP‐CPP » AMP. Females detect ATP and its analogues better than males. The ED 50 of ATP was 5 × 10 ‐7 M for teneral females and 1.5 × 10 ‐6 M for males. According to the potency order of the ATP analogues, the G.p.palpalis gustatory receptors recognizing ATP can be classified as P 2y purinoceptors.
