title: 2,6-Dichlorophenol in the tickRhipicephalus appendiculatus Neumann : A reappraisal.
abstract: Certain olfactory cells of maleRhipicephalus appendiculatus Neumann are known to be stimulated by 2,6-dichlorophenol.R. appendiculatus has been reexamined for the presence of 2,6-dichlorophenol, and it has been detected in both male and female adults. Unfed females contain 12 ng/ tick, declining to 2 ng/tick after six days of feeding, while unfed males contain 2 ng/tick, falling to 0 after feeding. Larval tick extracts which are also known to stimulate 2,6-dichlorophenol-sensitive cells were examined and found to contain this phenol, whereasR. appendiculatus eggs did not contain this compound.
