Abstract
Studies on the resting site preferences of the tsetse, Glossina palpalis gambiensis Vanderplank, were conducted in a gallery forest in the Northern Guinea Savanna in Mali. Tanglefoot was used to trap flies alighting to rest on the various site-types investigated. Five site-types were observed: boles, fallen logs, undergrowth (‘bush’), branches and tree canopies. Observations were made in the warm rainy, warm dry and hot dry seasons.
Distribution of resting flies on site-types was significantly heterogenous in each of the seasons. More than 80% of flies collected in each of the three seasons were found on fallen logs. Generally, there was no significant difference in numbers found on the top or side of fallen logs. Boles were the next best preferred site-type. Approximately 90% of flies on boles were collected below 1.0 m and none was found above 2.0 m. Few flies were collected from the undergrowth (bushes), tree canopies and branches. Similarities and differences between results obtained from the present study with those of other workers are discussed. The importance of the results in ground insecticide control operation against this species is noted.
