Abstract
Selected physiological states of female, egg, and larval Dermacentor andersoni (Stiles) (Ixodidae) were analyzed for fatty acids (FA) by gas-liquid chromatography. FA carbon chain lengths were C10 to C22. In all states except female postoviposition, the major FA (82–95%) were palmitic, stearic, oleic, linoleic, and an unidentified FA which is under investigation. In unfed and postoviposition females, the short-chained lauric and myristic FA showed a marked increase over the long-chained FA, probably indicating an active breakdown process. FA concentrations (mg/100 mg dry weight) varied from state to state but their proportions remained constant. FA concentrations in all tick homogenates were much less than in host rabbit serum and whole blood. The predominance of palmitic acid in host blood and of oleic acid in tick homogenates suggest a FA elongation and desaturation system in the tick.Keywords
