<div><p>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), 1×1 m black targets and small 25×25 cm targets with flanking nets was compared using electrocuting sampling methods. The work was done on <em>Glossina tachinoides</em> and <em>G. palpalis gambiensis</em> (Burkina Faso), <em>G. fuscipes quanzensis</em> (Democratic Republic of Congo), <em>G. f. martinii</em> (Tanzania) and <em>G. f. fuscipes</em> (Kenya). The killing effectiveness (measured as the catch per m<sup>2</sup> of cloth) for small targets plus flanking nets is 5.5–15X greater than for 1 m<sup>2</sup> 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.</p> </div>
