Biology of the non-parasitic phase of the cattle tick Rhipicephalus (Boophilus) microplus in an area of Amazon influence [PDF]

Parasites & Vectors
Background Rhipicephalus (Boophilus) microplus is the most important tick species affecting cattle in the world. Under field conditions, the non-parasitic phase of R. (B.) microplus is unknown in the Amazon biome, including Brazil.

Cholesterol in the Cuticular Wax of Boophilus microplus [PDF]

Nature, 1969
TRACES of substances giving colour reactions typical of sterols have been found in the cuticle and cuticular wax of several arthropods1–6, but they have not been reported from ticks7,8. I have now shown that both free and esterified cholesterol occur in the wax of Boophilus microplus, and I have measured the quantity of each present.

Metabolism of Coumaphos in Larvae of the Cattle Tick Boophilus Microplus [PDF]

Australian Journal of Biological Sciences, 1966
[82P]Coumaphos, a phosphorothionate, was rapidly absorbed and metabolized by cattle tick larvae dipped in aqueous suspensions of the acaricide. One metabolite was shown by chromatographic, spectroscopic, and cholinesterase inhibition evidence to be the oxygen analogue, a more potent in vitro cholinesterase inhibitor than the parent compound.

Boophilus microplus: Characterization of Enzymes Introduced Into the Host [PDF]

Australian Journal of Biological Sciences, 1976
A number of enzymes, presumably secreted by larvae of B. micro plus under natural feeding conditions, have been investigated in the skin of previously unexposed calves 4 h after infestation at the attachment site. Carboxylic ester hydrolase activity was demonstrated in the dermis, immediately adjacent to the mouthparts, or in the attachment cone ...
