About sand flies


Sensory Organs

The ascoid sensillum on the antennae of sand flies has been under examination for electrophysiological response to insect pheromones and kairomones (e.g. Dougherty et al., 1999 for the latter). Specific neurones in ascoid sensilla have been shown to respond to carboxylic acids, ketones, alcohols and aldehydes, components of 'attractive' fox odour.
