Abstract
Resting site preferences of adult Glossina morsitans morsitans Westw., the dominant species in the Republic of Zambia, were observed during the cool (May–August) and hot (September–October) dry seasons in 1974 at the Chakwenga Game Reserve. Tanglefoot was used to trap resting flies on boles, branches, bushes (undergrowth), canopies, fallen logs and in ant-bear holes.All resting flies were collected below 4 m and there was an inverse relationship between numbers of resting flies and height of resting sites on boles, branches and canopies. Most flies were collected betwen 06.00 and 09.00 h, except in ant-bear holes, where no flies were found. No significant differences existed between numbers of flies collected from the four cardinal positions on boles. Although more flies were found on shaded than unshaded fallen logs and bushes, the differences were only statistically significant for fallen logs. Numbers of flies on various tree species were generally not significantly different. Boles, bushes and fallen logs were the most preferred sites.
