| distribution and phenology of ixodid ticks in southern zambia. | 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 important ixodid ticks are also discussed. southern zambia is a transition zone because it is the most northern area in africa where mixed rhip ... | 2002 | 12510896 |
| transmission of theileriosis in the traditional farming sector in the southern province of zambia during 1995-1996. | the incidence of first contact with the protozoan theileria parva was determined in three traditional cattle herds in the southern province of zambia in 1995 and 1996. the majority of first contacts occurred during the dry season in june, july and august, at a time of nymphal activity and in the absence of rhipicephalus appendiculatus adults, indicating that larva to nymph transmission plays a more prominent role than nymph to adult transmission under the prevailing conditions. | 2000 | 11059039 |
| further evidence for geographic differentiation in r. appendiculatus (acari: ixodidae) from eastern and southern provinces of zambia. | studies in the biology, ecology and behaviour of r. appendiculatus in zambia have shown considerable variation within and between populations often associated with their geographical origin. we studied variation in the mitochondrial coi (mtcoi) gene of adult r. appendiculatus ticks originating from the eastern and southern provinces of zambia. rhipicephalus appendiculatus ticks from the two provinces were placed into two groups on the mtcoi sequence data tree. one group comprised all haplotypes ... | 2007 | 17340215 |
