Comparison of different systems for collecting tsetse and horse flies with two types of trap

Abstract

The efficiency of biconical (Challier-Laveissière) and monoconical (Mérot) traps with a cage or a bottle as the collecting system for Glossina tachinoides, G. morsitans submorsitans and the Tabanidae was evaluated in 1992 and 1994 at the Comoé site, Burkina Faso by CIRDES. The bottle increased the catches of G. tachinoides only when used with the monoconical trap, but the numbers collected were always smaller than with the biconical trap/cage system. The biconical trap with a bottle gave results which varied according to the year concerned, but these results were never more than equal to those with the cage. The differences were more significant in the catches of males. The biconical trap associated with a cage was the most efficient system for catching Glossina morsitans submorsitans. The bottle reduced the catches with both types of trap. The use of bottle increased (and sometimes doubled) the catches of horse flies with both types of trap.
