factors influencing seasonal and daily dynamics of the genus Stomoxys geoffroy 1762 diptera muscidae in the adamawa plateau cameroon
International Journal of Zoology, 2019Co-Authors: Sevidzem Silas Lendzele, Zingakoumba Christophe Roland, Mavoungou Jacques Francois, Koumba Aubin Armel, Gérard DuvalletAbstract:The rangelands of the Vina Division on the Adamawa Plateau are densely infested with Stomoxyinae, but little is known about their species composition and ecology. A trap-transect survey was carried out in three villages: Galim, Mbidjoro, and Velambai, using Nzi (n = 3), Vavoua (n = 3), and Biconical (n = 3) traps, all baited with octenol. Three traps of each trap type were set in each of the study villages, and collections were carried out daily. In total, 3,762 Stomoxys spp. were collected from October 2016 to June 2017 and identified using standard keys into five species: Stomoxys niger niger, S. calcitrans, S. niger bilineatus, S. omega, and S. xanthomelas. Galim recorded the highest apparent density of stomoxyines (30 stomoxyines/trap/day) with a statistically significant difference ( ). The Vavoua trap was an ideal tool for Stomoxyinae collection. Stomoxyines abundantly occurred at the end of the dry season (March 2017) and beginning of the rainy season (May 2017). The monthly rainfall positively influenced monthly ADTs of Stomoxyinae. Their diurnal biting activity was bimodal in the rainy season and unimodal in the dry season. The daily activity peak was between 14 h and 16 h with a mean temperature of 31°C, a mean wind speed of 1.5 m/s, and a mean humidity of 50%. The daily trap catch was positively influenced by temperature and wind speed but negatively influenced by rainfall and air humidity. Weather variables influenced Stomoxys spp. monthly and daily ADTs.

Species Composition and Abundance of Stomoxys spp. (Diptera: Muscidae) in Peninsular Thailand.
Journal of medical entomology, 2019Co-Authors: Sokchan Lorn, Gérard Duvallet, Sakda Ratisupakorn, Theeraphap Chareonviriyaphap, Krajana TainchumAbstract:Stable fly collections were conducted to study the species composition and daytime activity of Stomoxys spp. (Diptera: Muscidae) in Peninsular Thailand (Songkhla, Trang, Pattalung, Nakon Si Thammarat, and Satun provinces). Vavoua traps were used for fly collections in wet and dry seasons each year. Four Stomoxys species were found, S. calcitrans (L.) (Diptera: Muscidae) being the most common with 2,512 specimens (87.43% of captures), followed by S. indicus (Picard) (Diptera: Muscidae) with 306 specimens (10.65%), S. sitiens (Rondani) (Diptera: Muscidae) with 44 specimens (1.53%), and S. uruma (Shinonaga and Kano) (Diptera: Muscidae) with 11 specimens (0.39%). Subsequently, Songkhla Province was further selected to be a potential collection site to conduct a 1-yr abundance study, due to mixed crop-livestock farming in one place. Stomoxys calcitrans was predominant from 0800 to 1000 h with 4,921 specimens (93.6%) while S. indicus with 317 specimens (6%) and S. sitiens with 19 specimens (0.4%) were numerically dominant from 0600 to 0800 and 1600 to 1800 h. A proportion of male and female of each species was also established. This overall finding could be used as an ideal for nationwide species distribution status for the guidance of appropriate fly control. This information can lighten the way for the future control measures program activity of stable flies in Thailand.

breeding sites of Stomoxys spp diptera muscidae a preliminary study in the makokou region north east gabon
Vector Biology Journal, 2017Co-Authors: Jacques François Mavoungou, Gérard Duvallet, Jeremie R. L. Gilles, Rodrigue Mintsa Nguema, Genevieve Lydie Acapovi, Zinga Koumba, Franck Mounioko, Sevidzem Silas Lendzele, Ingrid Kindzi Bakakas, Nicolas PicardAbstract:In order to circumscribe the breeding sites of stomoxes in the Makokou region, eight potentially favorable environments were sampled from January to June 2007 in three habitats: primary and secondary forest (natural environments) and the anthropic environment (artificial or disturbed areas). In the primary forest, three types of substrates were collected: litter, elephant dung and Cephalophus droppings. In the secondary forest, two types of substrates: litter and monkey droppings. In villages or cities, three substrates constituting of: decaying plant material, organic waste from garbage in villages and cow dung were also collected. These materials were placed in emergence cages while awaiting the emergence of adult arthropods. In total, 14517 arthropods emerged, including 11726 stomoxes and 2791 other arthropod specimens. Seven Stomoxys spp were observed and included: S. transvittatus with 8221 (70%) emerged individuals, S. niger niger with 1679 (14%) observed individuals. However, S. omega (8%); S. inornatus (4%); S. calcitrans (2%); S. niger bilineatus (1.9%); and finally S. xanthomelas (0.1%) emerged in minor proportions. The results obtained in this study indicate that stomoxes can lay their eggs on several types of substrates hence colonizing many areas

Distribution and abundance of hematophagous flies (Glossinidae, Stomoxys, and Tabanidae) in two national parks of Gabon.
Parasite (Paris France), 2015Co-Authors: Paul Yannick Bitome Essono, François-xavier Dechaume-moncharmont, Jacques François Mavoungou, Régis Obiang, Gérard Duvallet, François BretagnolleAbstract: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.

transmission of pathogens by Stomoxys flies diptera muscidae a review
Parasite, 2013Co-Authors: Frederic Baldacchino, Gérard Duvallet, Vithee Muenworn, Marc Desquesnes, Florian Desoli, Theeraphap CharoenviriyaphapAbstract:Stomoxys flies are mechanical vectors of pathogens present in the blood and skin of their animal hosts, especially livestock, but occasionally humans. In livestock, their direct effects are disturbance, skin lesions, reduction of food intake, stress, blood loss, and a global immunosuppressive effect. They also induce the gathering of animals for mutual protection; meanwhile they favor development of pathogens in the hosts and their transmission. Their indirect effect is the mechanical transmission of pathogens. In case of interrupted feeding, Stomoxys can re-start their blood meal on another host. When injecting saliva prior to blood-sucking, they can inoculate some infected blood remaining on their mouthparts. Beside this immediate transmission, it was observed that Stomoxys may keep some blood in their crop, which offers a friendly environment for pathogens that could be regurgitated during the next blood meal; thus a delayed transmission by Stomoxys seems possible. Such a mechanism has a considerable epidemiological impact since it allows inter-herd transmission of pathogens. Equine infectious anemia, African swine fever, West Nile, and Rift Valley viruses are known to be transmitted by Stomoxys, while others are suspected. Rickettsia (Anaplasma, Coxiella), other bacteria and parasites (Trypanosoma spp., Besnoitia spp.) are also transmitted by Stomoxys. Finally, Stomoxys was also found to act as an intermediate host of the helminth Habronema microstoma and may be involved in the transmission of some Onchocerca and Dirofilaria species. Being cosmopolite, Stomoxys calcitrans might have a worldwide and greater impact than previously thought on animal and human pathogen transmission.

influence du degre de perturbation du milieu sur l activite journaliere des Stomoxys spp diptera muscidae au nord est du gabon
Sciences de la vie de la terre et agronomie, 2013Co-Authors: J F Mavoungou, Jeremie R. L. Gilles, Genevieve Acapovi Yao, Kohagne L Tongue, R Zinga C Koumba, O Mbang A Nguema, Obame P Ondo, B Mbatchi, Gérard DuvalletAbstract:Les rythmes circadiens des insectes hematophages constituent un facteur epidemiologique essentiel car ils determinent les moments de la journee ou s’effectue le contact entre l’hote vertebre et l’insecte. Afin de determiner les periodes d’activite journaliere des stomoxes dans le Parc National de l’Ivindo au Nord-est du Gabon, nous avons realise un suivi de l’activite journaliere des stomoxes (Diptera) le long d’un transect allant de la foret primaire a la ville de Makokou, en passant par la foret secondaire. Les stomoxes ont ete captures mensuellement a l’aide du piege Vavoua d'avril a juillet 2006 pendant quatre jours consecutifs au cours de chaque mois. Les resultats obtenus montrent que la densite et la composition specifique des stomoxes captures varient en fonction du niveau de perturbations des biotopes prospectes. En foret primaire, 597 stomoxes appartenant aux especes Stomoxys transvittatus (58%), S. omega (34%) et S. inornatus (8%) ont ete captures. Les especes S. inornatus et S. transvittatus ont une activite unimodale (entre 11h et 15h) tandis que S. omega presente deux pics d’activite, entre 5-7h et 17-19h. En foret secondaire, les captures sont 170 fois plus importantes et quatre especes additionnelles ont ete identifiees : Stomoxys calcitrans , S. niger niger , S. niger bilineatus , S. xanthomelas . Ces memes especes ont ete capturees en milieu anthropise. Dans ces deux biotopes, S. calcitrans , et S. niger bilineatus presentent une activite unimodale entre 11h et 13h alors que S. n. niger et S. omega ont des activites bimodales dans des tranches horaires differentes. Cette etude montre que les stomoxes du Parc National de l’Ivindo sont biologiquement diurnes avec un rythme d’activite module par des conditions de luminosite.

Spatio-temporal variation of biting flies, Stomoxys spp. (Diptera: Muscidae), along a man-made disturbance gradient, from primary forest to the city of Makokou (North-East, Gabon).
Medical and veterinary entomology, 2012Co-Authors: Jacques François Mavoungou, Jeremie R. L. Gilles, Nicolas Picard, L.t. Kohagne, Bertrand M’batchi, Gérard DuvalletAbstract:Understanding the pattern of abundance of vector populations is important to control the potential of transmission of associated pathogens. The pattern of abundance of Stomoxys Geoffroy, an ubiquitous blood-sucking fly, is poorly known in tropical Africa. In this study, we investigated the spatio-temporal pattern of abundance of the Stomoxys genus along a gradient of man-made disturbance in north-eastern Gabon. Three sites (one in primary forest, one in secondary forest and one in a man-made environment) were monitored during 13 months using Vavoua traps. Seven species and subspecies were found to live in sympatry, but with distinct patterns of abundance with respect to space and time. The most abundant species was Stomoxys transvittatus Villeneuve, whereas the rarest species was S. xanthomelas Roubaud. Stomoxys calcitrans Linne was preferentially found in man-made environments, whereas S. xanthomelas was preferentially found in primary forest. Stomoxys abundance was the greatest in secondary forest, then in man-made environments and finally in primary forest. A seasonal variation in Stomoxys abundance was also found. In conclusion, forest degradation and deforestation are likely both to favour the concentration of populations of Stomoxys, and to change the specific composition of the Stomoxys community.

effects of temperature on the rate of increase of Stomoxys calcitrans and Stomoxys niger niger diptera muscidae from la reunion island
Journal of Medical Entomology, 2005Co-Authors: Jeremie R. L. Gilles, Jeanfrancois David, Gérard DuvalletAbstract:Adult survival and reproduction were compared between two Stomoxys species that co-occur in La Reunion, the cosmopolitan Stomoxys calcitrans (L.), and the tropical Stomoxys niger niger Macquart. In a Þrst experiment, mean longevity and fecundity were determined at Þve constant temperatures from 15 to 35C, after development at the same temperatures. Adult longevity was greatest at 20 Ci nS. calcitrans and at 15 Ci nS. niger. Adult S. niger survived longer than adult S. calcitrans, especially at 15C. At 35C, all sies died within 3 d. Reproduction occurred only within the 20 Ð30C range, and S.niger laid more eggs than S.calcitrans. In both species, lifetime fecundity tended to decrease when temperature increased, because of the shortening of the oviposition period. In a second experiment, adults were maintained at 15C after development at 25C. The higher temper- ature during development signiÞcantly increased adult longevity in S. calcitrans but not in S. niger. Reproduction occurred at 15C, with notable fecundity in S. calcitrans (22 eggs per female) but not in S. niger (1 egg per female). Using previous results on immature survival and developmental time in the two species, several life history parameters were compared at each temperature. Generation time decreased with increasing temperature and was highly similar in both species. Concurrently, the intrinsic rate of increase (r) increased with temperature from 15 to 30C. At 15C, r was higher in S. calcitrans, but within the 20 Ð30C range, r was higher in S. niger. The results suggest 1) S. niger has evolved a strategy of survival without any reproduction during the tropical winter, in contrast with S.calcitrans that breeds more continuously; and 2) S.niger may outnumber S.calcitrans in warm areas, at least when development occurs in media of poor quality.

temperature effects on development and survival of two stable flies Stomoxys calcitrans and Stomoxys niger niger diptera muscidae in la reunion island
Journal of Medical Entomology, 2005Co-Authors: Jeanfrancois David, Jeremie R. L. Gilles, Gérard DuvalletAbstract:Abstract Two stable fly species, Stomoxys calcitrans (L., 1758) and Stomoxys niger niger Macquart, 1851, co-occur in La Reunion, where they are important pests of cattle. The survival and developmental rate of the immature stages were compared at five constant temperatures from 15 to 35°C. In both species, immature survival was highest at 20–25°C and markedly decreased at 15 and 35°C. At the lower temperatures, mortality was observed mainly for S. calcitrans larvae and S. niger eggs. At the higher temperatures, mainly pupae of both species died. At all temperatures, S. calcitrans survived better than S. niger. Developmental time was highly similar in both species, decreasing from 71 d at 15°C to 13 d at 30°C in S. calcitrans and from 69 d at 15°C to 14 d at 30°C in S. niger. Developmental times increased slightly at 35°C. Surprisingly, the tropical S. niger developed slightly faster than the cosmopolitan S. calcitrans at 15–20°C; the reverse was found at higher temperatures. Temperature summation models c...

mechanical transmission of lumpy skin disease virus by Stomoxys spp Stomoxys calsitrans Stomoxys sitiens Stomoxys indica diptera muscidae
Open Access Journal, 2020Co-Authors: Arman Issimov, Lespek Kutumbetov, Mukhit Orynbayev, Berik Khairullin, Balzhan Sh Myrzakhmetova, Kulyaisan T Sultankulova, Peter WhiteAbstract:Samples collected for PCR from recipient animals tested positive in 5 out of 6 cases, while the virus was isolated from 4 of 6 animals. The clinical signs exhibited by recipient animals were mostly moderate in nature with only one severe case. To our knowledge, this is the first time that transmission of LSDV by three Stomoxys species has been demonstrated, and their role as mechanical vectors of LSDV is indicated.
