Evaluation of adhesive film as monitoring tool for riverine tsetse flies (Diptera, Glossinidae) in Burkina Faso

Abstract

Tsetse flies (Diptera: Glossinidae) are the cyclical vectors of human (HAT) and animal (AAT) trypanosomiasis in sub-Saharan Africa, which constitutes a  major constraint for human and animal health. Tsetse populations can be reduced using a variety of techniques. This studies aimed to validate the use of  adhesive film as a measurement tool for riverine tsetse flies. For this study, two targets have been used. 1mx1m targets and small 0.25mx0.25m targets  with adhesive film were compared using electrocuting sampling methods. Four treatments were compared for 12 days in a 4x4 latin square at Folonzo  and Solenzo. Our results showed that the large targets (1mx1m black/blue/black BlkBBlk)) (film or grid) captured significantly more G. tachinoides and G.  p. gambiensis than the reduced targets (0.25mx0.25m BlkBBlk) (p ≤0, 001) ..For the large targets (1mx1m) G. tachinoides was significantly attracted on  target covered adhesive film (27.91 flies/day) compared to the electric grid (19.65flies/day); p ≤0, 1. The effect of adhesive film on color show also that the  blue color of the 1mx1m BlkBBlk film was significantly more attractive than the target (1mx1m BlkBBlk) in the grid for G. tachinoides. No difference was  observed between the targets with film and grid for the two colors (blue and black) for G. p. gambiensis in Folonzo and Solenzo. We conclude that  adhesive film could be used as a strategic control tool against African Trypanosomiasis vectors.
