dc.description.abstract | Insecticides utilised in the field to control tsetse flies often do not reach
their targets in sufficient quantities to kill them. The effects of such sublethal
doses on the reproduction of these flies is therefore important in assessing fly
populations after spray applications.
Various concentrations of deltamethrin and the natural pyrethrum extract
from 10-14 to 15 nanograms per micro liter (ng/ul) of the insecticides in
redistilled acetone were topically applied (1 ul/fly) on the dorsal thorax of wild
caught Glossina pallidipes Austen and laboratory reared Glossina morsitallS
morsitans Westwood females 24 hours after they took a blood meal. Flies were
also hand held on insecticide treated glass and cloth surfaces to allow transfer of
the chemicals. Treated and control flies were maintained and fed daily until
death. | en |
