Abstract: | ABSTRACT. 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 (ED50) 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 ED50 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 P2y purinoceptors. |
