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.
