Autor: W F Snow, Eric Denison, P. S. Mellor, C Hamblin, J. Boorman, P Rawlings
Publikováno v: Medical and Veterinary Entomology. 12:155-159
Twelve light trap collections made near overnight shelters of horses and donkeys in four villages in the Central River Division of The Gambia captured fourteen species of biting midge of the genus Culicoides. Five species new to The Gambia were ident

Observations on the prevalence of trypanosomosis in small ruminants, equines and cattle, in relation to tsetse challenge, in The Gambia
Autor: P. Rawlings, W. F. Snow, T. J. Wacher
Publikováno v: Veterinary Parasitology. 66:1-11
The prevalence of trypanosome infections in Djallonke sheep and West African Dwarf goats at different sites in The Gambia showed a significant, positive correlation with contemporary assessments of tsetse challenge. A similar correlation was observed

The spectral sensitivity of Aedes aegypti (L.) at oviposition
Autor: W. F. Snow
Publikováno v: Bulletin of entomological research. 60(4)
The spectral sensitivity of gravid female Aedes aegypti (L.) was investigated in the laboratory using their responses to oviposition sites illuminated by light of defined intensity and spectral composition. An inverse relationship between the illumin

Tsetse–trypanosomiasis challenge to village N'Dama cattle in The Gambia: field assessments of spatial and temporal patterns of tsetse–cattle contact and the risk of trypanosomiasis infection
Autor: W. F. Snow, T. J. Wacher, Paul Milligan, P. Rawlings
Publikováno v: Parasitology. 109:149-162
SUMMARYThe severity of the trypanosomiasis problem in a particular location is traditionally assessed in terms of a challenge index – the product of some measure of tsetse abundance and infection rate – which is assumed to be proportional to the

The distribution of the tsetse flies Glossina morsitans submorsitans and G. palpalis gambiensis (Diptera: Glossinidae) in The Gambia and the application of survey results to tsetse and trypanosomiasis control
Autor: M.L. Ceesay, P. Rawlings, W. F. Snow, T. J. Wacher
Publikováno v: Bulletin of Entomological Research. 83:625-632
A country-wide survey of the distribution of tsetse flies Glossina morsitans submorsitans Newstead and G. palpalis gambiensis Vanderplank was carried out in The Gambia, during 1989–1990, using box traps at 1654 sites over an area of 10,000 km2 The

Cattle-tsetse contact in relation to the daily activity patterns of Glossina morsitans submorsitans in The Gambia
Autor: P. Rawlings, T. J. Wacher, W. F. Snow
Publikováno v: Medical and veterinary entomology. 8(1)
The daily flight activity patterns of one of the main vectors of animal trypanosomiasis in West Africa, Glossina morsitans submorsitans, were assessed using four different methods. Results from all the methods showed that there was some flight activi

Watering sites in Glossina fuscipes habitat as the major foci for the transmission of Gambiense sleeping sickness in an endemic area of southern Sudan
Autor: W F, Snow, J, Declercq, S, van Nieuwenhove
Publikováno v: Annales de la Societe belge de medecine tropicale. 71(1)
In an area of endemic gambiense sleeping sickness in southern Sudan, the vegetation around 40 wells was categorised in terms of potential habitat for the vector, Glossina fuscipes, and the probability of repeated man/fly contact. These observations w

Autor: W. F. Snow, D. A. Turner
Publikováno v: Bulletin of Entomological Research. 74:299-309
The nature, frequency and causes of reproductive loss were investigated in populations of Glossina pallidipes Aust. in western and coastal localities in Kenya. Daily collections from biconical traps in which females were trapped for varying periods u
