Distribution and abundance of hematophagous flies (Glossinidae,Stomoxys, and Tabanidae) in two national parks of Gabon

Abstract

In order to minimize risks of pathogen transmission with the development of ecotourism in Gabon, a seasonal inventory has been performed in five contrasted biotopes in Ivindo (INP) and Moukalaba-Doudou (MDNP) National Parks. A total of 10,033 hematophagous flies were captured. The Glossinidae, with six different species identified, was the most abundant group and constitutes about 60% of the captured flies compared to the Stomoxys (6 species also identified) and Tabanidae with 28% and 12%, respectively. The Glossinidae showed a higher rate of capture in primary forest and in research camps. In INP, the Stomoxys showed a higher rate of capture in secondary forest and at village borders, whereas in MDNP the Stomoxys were captured more in the savannah area. Thus, each fly group seemed to reach maximum abundance in different habitats. The Glossinidae were more abundant in primary forest and near research camps while Stomoxys were more abundant in secondary forest and savannah. The Tabanidae did not show a clear habitat preference.

Prevalence of Trypanosoma evansi in Dromedary Camels (Camelus dromedarius) and Its Possible Mechanical Vectors in Al Kharj Town, Riyadh Region, Saudi Arabia

“…In our present study, high catches of flies were achieved from water station and people houses more than other sites. These findings are similar to the studies conducted by several authors who reported that stable flies are present in many habitats (Grimaud, 2013;Zinga et al, 2013;Bitome et al, 2015). The presence of stable flies is associated with unsanitary conditions and is more present in anthropic environments.…”

Detection of Trypanosoma evansi in camel abortions (Camelus dromedarius) in Iran using polymerase chain reaction

“…Hematophagous flies cause mechanical transmission, which leads to the transmission of the disease to other parts of the world [2]. It should be noted that vampire bats have been identified as carriers of the disease in South America [4,6]. Trypanosoma evansi occurs in acute and chronic forms because the suppression of the immune system causes secondary infections [7].…”

Abundance and Diurnal Activity Rhythm of Stomoxys spp. in a Wildlife-human Interface in Makokou (North East-Gabon)

“…In Gabon (a neighbouring country to Cameroon), the knowledge of Stomoxys in the wildlife-human interface of Makokou is scanty [7,8,9,10] especially on the diurnal activity rhythm of this group with respect to sex. There is need to update on the knowledge of Stomoxyinae in the area because they represent a risk for the human and animal population through their direct nuisance (precludes outdoor activities such as ecotourism, etc..) and by their vectoral role.…”
