Comparison of characteristics of life cycle in female ticks collected on N'Dama and zebu cattle.
Characteristics of the life cycle of female ticks (Amblyomma variegatum, Hyalomma truncatum and Boophilus geigyi) fed on N'Dama and zebu cattle were studied in the laboratory from pre-oviposition period to larval development. Percentage of A. variegatum eggs hatched and engorgement weight of H. truncatum were lower in ticks collected on N'Dama than on zebu cattle. Laboratory results confirmed field observations of species specific tick resistance in the N'Dama breed.
