Taste stimuli for tsetse flies on the human skin

Insects transmit disease to hundreds of millions of people a year, and cause enormous losses to the world's agricultural output. Many insects find the human or plant hosts on which they feed, and identify and locate their mates, primarily through olfaction and taste. Major advances have recently been made in understanding insect chemosensation at the molecular and cellular levels. These advances have provided new opportunities to control insects that cause massive damage to health and agriculture across the world.

The effect of ox skin secretions (sebum) on the behaviour of tsetse flies, Glossina spp., was investigated in the field using electrified targets, some of which operated intermittently, and by direct observations of flies landing on treated and untreated cloth. As the off-period of an intermittently operating electrified target increased, the catch decreased both with and without the sebum present. Targets with sebum always caught more flies than targets without sebum, but there was no evidence to suggest that sebum increased the duration of stay on a target. Direct observations of flies on cloth targets revealed that for both species the presence of sebum reduced the duration of contact and for G.pallidipes the number of return contacts was increased. The results from direct observations were used to predict the number of repeat landings that would need to be made by flies in order to account for the catch of tsetse at intermittently electrified targets.
