Abstract

The sampling method yielded large numbers of both sexes of Simulium squamosum, S. hargreavesi, S. vorax, S. adersi, S. hirsutum, and other species. The main peak of activity of all species recorded occurred just after sunset; there was a smaller peak just before sunrise. Flies continued to be caught at a low level 2.5 h after sunset when sampling ceased. Of the S. squamosum females caught, 12% were blood-fed; these and gravid females were mainly active in the evening, while the blood-thirsty flies had a high level of activity throughout the day. Differences between species in the relative activity of blood-thirsty and gravid flies, and nulliparous and parous flies are noted. -from Authors
