Laboratory bioassays of deltamethrin, topically applied, during the hunger cycle of male Glossina tachinoides

Abstract

The susceptibility of mature and immature male Glossina tachinoides to topically applied deltamethrin was tested on successive days of their hunger cycle. Both in mature and immature flies, significant changes in tolerance were observed correlated to the digestion of the bloodmeal. In mature tsetse, the fly’s fat level is also correlated to its susceptibility.
