Sensilla basiconica (grooved pegs) on the antennae of female mosquitoes: electrophysiology and morphology

1995

Bowen, M.F.

The sensilla basiconica or grooved pegs of mosquitoes consist of two morphologically and functionally distinct classes. Short grooved pegs house sensory cells that are excited by lactic acid whereas lactic acid-excited cells are absent in long grooved pegs. This correlation was found in four species of mosquito examined: Aedes aegypti, Aedes atropalpus, Aedes epactius, and Culex pipiens. In Aedes epactius, both short and long grooved pegs house receptors that are sensitive to butyric acid.
