Abstract:
Background and Objective: The pasture area of the Adamawa Plateau was heavily infested with haematophagous flies. Field trials to suggest an efficient anti-vectoral method to farmers was required. The present field trial aimed at evaluating the efficacy of Deltik® 5% Industrially Incorporated (IIS) and Manually Incorporated (MIS) ZeroFly® screen models together with ZeroFly® Nzi and Biconical traps in biting insect control. Materials and Methods: To realize this study, Biconical and Nzi traps were used to monitor the population of vectorspre and post-screens installation using sites in the DFG cattle paddock and abattoir. The functionality test of screens was carried out by choosing two other sites i.e., the Galim Tick Bath (GTB) as the unscreened site and the Ngaoundere Modern Abattoir (NMA) as the screened site. The pre and post-intervention monitoring activities were carried out in the dry (March) and rainy (April) seasons in 2017. The screen functionality test was carried out in May, 2017. Results: Overall, six families of vectors were identified: Tabanidae, Culicidae, Ceratopogonidae, Muscidae and Simuliidae as well as by-catches. Eleven genera were identified and 21 species were regrouped under them. The overall initial trap apparent density (TADi) of vectors was 21.79 flies/trap and that post-intervention (TADf) was 5.73 flies/trap and day. The overall screen reduction rate was 73.70% and was taxonomic group (family, genus and species) dependent. The IIS reductionrate was 79.20%, while that of MIS was 68.29% with no statistically significant difference (p = 0.06). Conclusion: Thepresence of ZeroFly® screen models and traps in the pasture area of Vina du Sud reduced the biting vectors pressure.
