Relative resistance of six cattle breeds to the tick Boophilus decoloratus in South Africa.
Adult females of the tick Boophilus decoloratus were removed from 6 breeds of cattle on 2 farms in the Northern Transvaal. Highest numbers of female ticks were collected from Simmentaler, followed by Santa Gertrudis, Bonsmara, Afrikaner, Brahman and Nguni. Resistance levels of each breed to B. decoloratus was positively correlated with the amount of Bos indicus genes in the breed, with the exce...
متن کاملIdentification of a mutation in the para-sodium channel gene of the cattle tick Rhipicephalus (Boophilus) microplus associated with resistance to synthetic pyrethroid acaricides.
Resistance against synthetic pyrethroid (SP) products for the control of cattle ticks in Australia was detected in the field in 1984, within a very short time of commercial introduction. We have identified a mutation in the domain II S4-5 linker of the para-sodium channel that is associated with resistance to SPs in the cattle tick Rhipicephalus (Boophilus) microplus from Australia. The cytosin...
متن کاملProstaglandin in the saliva of the cattle tick Boophilus microplus.
Previous studies of saliva from engorged female cattle ticks revealed a component which induced contration of some isolated smooth muscles. Fractionation and further characterisation have shown that this substance is of the "slow-reacting" type, but that it is neither a bradykinin nor slow-reacting substance of anaphylaxis. The substance is deactivated by incubation with 15-hydroxprostaglandin ...
متن کاملTripanosomatides like Trypanosoma theileri in the cattle tick Boophilus microplus.
Findings of epimastigotes forms of a tripanosomatide is reported in the hemolymph of the cattle tick Boophilus microplus in the state of Rio Grande do Sul, southern Brazil. Morphological evidences suggest they are similar to Trypanosoma theileri, a species described as non pathogenic to cattle, and usually transmitted by tabanids.
متن کاملDetection and characterization of amitraz resistance in the southern cattle tick, Boophilus microplus (Acari: Ixodidae).
Amitraz, a formamidine acaricide, plays an important role in the control of the southern cattle tick, Boophilus microplus (Canestrini), and other tick species that infest cattle, dogs, and wild animals. Although resistance to amitraz in B. microplus was previously reported in several countries, the actual measurement of the level of amitraz resistance in ticks has been difficult to determine du...
