“…These surveys, conducted from 2015 to 2017, led to the identi cation of 25 species, much less than the 84 species recorded in the preliminary study of 1970 [17]. However, 8 species not previously recoded in Cameroon were identi ed, including: Tabanus Latipes Macquart, 1838 (1 ), Tabanus ricardae Surcouf, 1906 (1 ), Tabanus fasciatus Fabricus, 1775 (32 , 6 ), Haematopota pluvialis Linnaeus, 1758 (18 ), Haematopota decora Walker, 1850 (19 , 3 ), Haematopota nigripennis Austen, 1914 (18 ), C. distinctipennis Austen, 1906 (47 , 5 ) and Ancala fasciata Fabricus, 1977 (34 , 7 ). The new species record increases the list of the Tabanidae identi ed in Cameroon to 92 species and is higher than that reported in the other countries within the Afro-tropical region, including Central African Republic [18], Ivory…”

Background: Tabanid flies are a neglected group of haematophagous dipterans, yet contains 4400 species, regrouped under 144 genera. They are mechanical vectors of important pathogens, including viruses, bacteria and protozoa of humans, domesticated and wild animals. As it is over 50 years since publication of a preliminary nationwide record of tabanids of Cameroon identified 84 species, updated information is provided.Objective: To provide current data on the species composition, abundance and distribution of Tabanidae of Cameroon in the 5 main agro-ecological zones (AEZs).Methods: From 2015-2017, a systematic entomological prospection using Nzi, Vavoua, Biconical and Sevi traps (N=106) was conducted in 604 trap-points over 11,448 traps days, in the 5 main AEZs of Cameroon.Results: A total of 25,280 tabanid specimens were collected, identifying 25 species with 8 not previously documented in Cameroon, including: Tabanus Latipes Macquart, 1838 (1 ♀), Tabanus ricardae Surcouf, 1906 (1 ♀), Tabanus fasciatus Fabricus, 1775 (32 ♀♀, 6♂♂), Haematopota pluvialis Linnaeus, 1758 (18 ♀♀), Haematopota decora Walker, 1850 (19 ♀♀, 3 ♂♂), Haematopota nigripennis Austen, 1914 (18 ♀♀), C. distinctipennis Austen, 1906 (47 ♀♀, 5 ♂♂) and Ancala fasciata Fabricus, 1977 (34 ♀♀, 7 ♂♂). The distribution maps of the newly identified tabanids differed between AEZs, with most from the Guinean savanna. The highest Tabanidae apparent density (ADT) was recorded in the Sudan savanna region and the mean apparent densities of species with type-localities was statistically significantly different (Student t-test=2.519, df=24, P=0.019). The highest species diversity was found in the rain forest.Conclusions: This study increased the list of Tabanidae recorded in Cameroon from 84 species in the preliminary record to 92 species, with most of the newly identified species occurring in the Guinean savanna AEZ. The high diversity and abundance of Tabanidae in the livestock/wildlife interface areas of the rain forests and Sudan savanna AEZs respectively, suggests risk of mechanical transmission risk of pathogens. Investigations of the microbiota within the Tabanidae in the different AEZs to define their role as disease vectors are proposed.

Background Tabanids are a neglected group of haematophagous dipterans despite containing 4434 species, regrouped in > 144 genera. They are mechanical vectors of important pathogens, including viruses, bacteria and protozoa of humans and domesticated and wild animals. As it is > 50 years since the publication of a preliminary nationwide record of the tabanids of Cameroon identified 84 species, updated information is needed. The aim of this study was to provide current data on the species composition, abundance and distribution of tabanids in the five main agro-ecological zones (AEZs) of Cameroon. Methods From 2015 to 2017, a systematic entomological study using Nzi, Vavoua, Biconical and Sevi traps (n = 106) was conducted in 604 trapping points over 11,448 trap-days in the five main AEZs of Cameroon. Results A total of 25,280 tabanids belonging to 25 species were collected, including eight species not previously documented in Cameroon, namely Tabanus latipes (1 female), Tabanus ricardae (1 female), Tabanus fasciatus (32 females and 6 males), Haematopota pluvialis (18 females), Haematopota decora (19 females and 3 males), Haematopota nigripennis (18 females), Chrysops distinctipennis (47 females and 5 males) and Ancala fasciata (34 females and 7 males). The distribution maps of the newly identified tabanids differed between AEZs, with most tabanids collected from the Guinean savanna. The highest apparent density of tabanids was recorded in the Sudan Savanna region, and the mean apparent densities of species with sites was statistically significantly different (Student t-test: 2.519, df = 24, P = 0.019). The highest species diversity was found in the rainforest. Conclusions This study increased the list of tabanids recorded in Cameroon from 84 species in the preliminary record to 92 species, with most of the newly identified species occurring in the Guinea Savanna AEZ. The high diversity and abundance of tabanids in the livestock/wildlife interface areas of the rain forests and Sudan Savanna AEZs, respectively, suggest risk of mechanical transmission of pathogens. Investigations of the microbiota of tabanids in the different AEZs to define their role as disease vectors are proposed. Graphical abstract

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

et al. 2015

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.
