“…The Wonders of Diptera -Characteristics, Diversity, and Significance for the World's Ecosystems This distribution could be explained by the differences in the environmental and microclimatic factors of the divisions which might have created conditions more or less favorable for the development and survival of tabanids. This observation is similar to that made by Mavoungou et al [11], Zinga et al [19,20] and Doumba et al [31]. These authors observed a heterogeneous distribution of tabanids following the structuring of the prospected milieu.…”

“…In Gabon, knowledge on tabanids in livestock farms is lacking. However, previous studies conducted by Mavoungou et al [11] and Zinga et al [19,20] at the Ivindo National Park showed that several tabanid species co-existed in sympatry in the different biotopes prospected. In addition, the report of Obame et al [21] in traditional livestock farms in north Gabon highlighted the presence of bloodfeeding flies in this region.…”

To embark on an anti-vectorial fight against mechanical vectors of animal trypanosomosis, investigations were undertaken in order to determine the abundance, species diversity and daily activity of tabanids in a cattle ranch in Gabon. The nzi and vavoua traps were used to catch tabanids in three divisions of this ranch. In this study, 616 tabanids were captured: 349 (56.66%) in Division 1, 226 (36.69%) in Division 2 and 41 (6.66%) in Division 3. In the first Division, T. taeniola was the most abundant species with an Apparent Density (ADT) of 2.2, followed by H. pluvialis (ADT = 1.05). In the second Division, H. pluvialis was most abundant with ADT of 1.6, followed by T. taeniola (ADT = 0.38). In the last Division, the most abundant species was H. pluvialis (ADT = 0.15). Comparing the relative abundance of catches with sites (Divisions), we realized that there was no statistically significant difference in catches with trapping sites. It was noticed that Division 3 recorded the highest diversity index values. We realized that the nzi trap recorded higher tabanid catches than the vavoua trap. The diurnal activity rhythm of the most frequent species encountered slightly differed with prospection sites.

“…According to Itard and Bauer (1984), antibiotic residues destroy intestinal and ovarian symbionts (Wigglesworthia, Soladis and Wolbachia), thus compromising the fertility and lifespan of female tsetse. It has been shown that a tsetse population lacking Wigglesworthia sterilised females but not males and succumbs rapidly to trypanosome infection (Pais et al, 2008;Wang and Aksoy, 2012;Weiss et al, 2012). These factors mentioned above need to be controlled and well monitored for successful tsetse production, in addition to the insectary internal and external environmental conditions.…”

With the goal of eradicating tsetse flies and trypanosomiasis in Africa, several control methods have been developed. One of this is the biological control through the application of the sterile insect technique (SIT) as a part of an area-wide integrated pest management. This method required the mass production of sterile males with a high competitiveness. The success of the tsetse mass rearing is strongly linked to the rearing conditions. The objective of this study was to do a retrospective evaluation of the impact of ambient conditions on the production performances of Glossina palpalis gambiensis at Insectary of Bobo Dioulasso. Data of productivity, fecundity, adult emergence and environmental conditions (temperature and relative humidity) of the rearing rooms were recorded from March to June 2020 and were analysed. The results showed a reduction of the normal pupae produced and the increase of soft pupae during this period. In addition, the relative humidity has shown a significant positive correlation with the production of soft pupae, whereas it had a significant negative correlation with the number of pupae produced per female per 10 days. However, the temperature variation during the period of the data recording didn’t have any impact on the production parameters. Rearing rooms need a better management to avoid large variations in environmental parameters.

“…(Mavoungou, 2007). Ces résultats corroborent ceux obtenus par Mavoungou et al (2008) et Zinga et al (2014a, 2014b qui ont montré que les stomoxes sont plus abondants en forêt qu'en milieu anthropisé. De plus, le microclimat pourrait jouer aussi un rôle dans la répartition et l'abondance des différentes espèces de stomoxes.…”

Bien que l'importance des glossines dans la transmission des trypanosomes soit connue au Gabon, elle a longtemps masqué celle des stomoxes. C'est dans ce cadre qu'une étude sur la chorologie des Stomoxyinae a été conduite, en grande saison sèche et à l'aide de pièges Vavoua, dans un ancien foyer de la Trypanosomose Humaine Africaine (THA) en particulier dans le Parc National de Moukalaba Doudou (PNMD). Au total 14 pièges Vavoua ont été placés dont 7 au village Doussala et 7 en forêt que sont les deux biotopes prospectés dans le PNMD. L'enquête entomologique a permis de mettre en évidence six (6) espèces de stomoxes qui vivent en sympatrie avec des densités apparentes (DAP) différentes suivant les espèces. En effet, Stomoxys omega avec une densité appaente par piège de 47,94 a été l'espèce la plus abondante, suivi de Stomoxys niger niger (DAP=19,49). Les autres espèces à savoir Stomoxys xanthomelas, Stomoxys niger bilineatus, Stomoxys calcitrans et Stomoxys transvittatus ont été très faiblement représentées avec des densités apparentes respectives de 0,25 ; 0,23 ; 0,012 et 0,004. La forte abondance des stomoxes dans ce parc nous interpelle à considérer ces insectes dans la lutte contre la THA dans cet ancien foyer.
