The results of tick surveys carried out in the Eastern province of Zambia between December 1982 and February 1996 were principally in agreement with the findings of earlier surveys conducted during the period 1965-72. Boophilus decoloratus has almost been replaced by Boophilus microplus. Hyalomma truncatum was found in small numbers throughout the province(More)
Distribution data for epidemiologically important ticks (Acari: Ixodidae) in the Southern Province of Zambia, one of the main cattle areas of the country, are presented. Boophilus microplus (Canestrini) was not recorded in southern Zambia, whereas Boophilus decoloratus (Koch) is present throughout the area. New distribution patterns for less economically(More)
Early in 2007, during a small-scale survey of the ticks infesting cattle in Azaguié about 50 km north of Abidjan, Ivory Coast, ticks, belonging to a species which to our knowledge had never been reported in West Africa before, were encountered. Boophilus microplus was the only member of this genus collected from cattle in the area. No Boophilus annulatus or(More)
Indigenous Culicoides biting midges are suggested to be putative vectors for the recently emerged Schmallenberg virus (SBV) based on SBV RNA detection in field-caught midges. Furthermore, SBV replication and dissemination has been evidenced in C. sonorensis under laboratory conditions. After SBV had been detected in Culicoides biting midges from Belgium in(More)
A new method has been developed to investigate behavioral diapause in adult Rhipicephalus appendiculatus ticks. It is based on a system of gauze columns in which the activity of the ticks can be monitored in the laboratory. An experiment was conducted, involving different photoperiodic conditions during the nymph-to-adult moulting and pre-questing periods,(More)
The invasive character of Rhipicephalus microplus was observed in Benin, the second West-African country from which this ticks species has been collected after the initial confirmed record in Ivory Coast in 2007. A cross-sectional study was carried out in the Department of Mono to examine the presence of the tick R. microplus. The survey covered 9 herds(More)
To identify possible vectors of Schmallenberg virus (SBV), we tested pools containing heads of biting midges (Culicoides) that were caught during the summer and early autumn of 2011 at several places in Belgium by real-time RT-PCR. Pools of heads originating from following species: C. obsoletus complex, C. dewulfi and C. chiopterus were found positive,(More)
In response to the first bluetongue outbreak in Belgium a monitoring programme was started at the end of August 2006 to identify possible vectors transmitting the disease. Black light traps were deployed at 36 outbreak sites and captured 1959 Culicoides specimens belonging to 16 different species. Eighty four percent of the biting midges captured belonged(More)
The cattle tick Rhipicephalus (Boophilus) microplus is known to be a highly reproductive and efficient vector of Babesia bovis, two characters which make this tick a threat to livestock keeping in many continents. The authors identified this tick in Ivory Coast, West Africa, in 2007, and hypothesized the spread to be minimal, as this tick was not observed(More)
