Abstract

Abstract. Experiments were carried out to improve the NG2B tsetse trap (Brightwell et al., 1987), baited with acetone and cow urine, for use by rural communities to control G.pallidipes Austen and G. longi‐pennis Corti. Modifications included a lower dose rate of acetone, a new cage design and raising the trap about 15‐20cm. Research on different trap cone materials showed that the degree of light transmission of the netting, rather than its colour, was the crucial factor affecting the catch of G.pallidipes. Adding an additional metre of blue cloth to one side of the trap increased catches of females of both species by about 60%. Traps baited with synthetic phenols yielded similar numbers of G.pallidipes and significantly more G.longipennis than those baited with natural cow urine. The latter difference was not apparent when octenol was also used, so cow urine was retained as one of the odour baits in preference to the imported phenols. Although octenol increased catches of G.pallidipes by only about 30%, catches of G.longipennis were increased 2–4‐fold, making it a very useful attractant for the latter species. The cost of the trap/odour‐bait system was estimated to be US$8.5 per unit per annum. The economics of this method of tsetse control are discussed. Copyright © 1991, Wiley Blackwell.
