Improving the cost-effectiveness of visual devices for the control of riverine tsetse flies, the major vectors of human African trypanosomiasis

Abstract

Control of the Riverine (Palpalis) group of tsetse flies is normally achieved with stationary artificial devices such as traps or insecticide-treated targets. The efficiency of biconical traps (the standard control device), ×ばつ1 m black targets and small ×ばつ25 cm targets with flanking nets was compared using electrocuting sampling methods. The work was done on Glossina tachinoides and G. palpalis gambiensis (Burkina Faso), G. fuscipes quanzensis (Democratic Republic of Congo), G. f. martinii (Tanzania) and G. f. fuscipes (Kenya). The killing effectiveness (measured as the catch per m(2) of cloth) for small targets plus flanking nets is 5.5-15X greater than for 1 m(2) targets and 8.6-37.5X greater than for biconical traps. This has important implications for the costs of control of the Riverine group of tsetse vectors of sleeping sickness.

Figure 3. Landing or entering response for tsetse on a standard target 1m2 (ST), a small ×ばつ25cm target (TT) or biconical trap (T).
For devices with a flanking net, landing or entering responses were estimated by expressing number caught landing on the target or entering the trap as a percentage of the total (device+flanking net) catch. For unaccompanied traps and targets, capture efficiency was estimated by expressing the mean catch of the trap or target as a proportion of the mean catch from a trap+flanking net. A = G. p. gambiensis at Solenzo; B = G. p. gambiensis at Folonzo; C = G. tachinoides; D = G. f. quanzensis; E = G. f. fuscipes. *Data for G. f. fuscipes derived from Lindh et al., 2009.
