2,6-DICHLOROPHENOL, THE SEX PHEROMONE OF THE ROCKY MOUNTAIN WOOD TICK, Dermacentor andersoni STILES AND THE AMERICAN DOG TICK, Dermacentor variabilis (SAY)

2,6-Dichlorophenol is the only active sex attractant component detected in the extracts of the Rocky Mountain wood tick, Dermacentor andersoni Stiles and the American dog tick, Dermaeentor variabilis (Say). It elicits from the male of each species a hierarchy of responses culminating in copulation. This compound probably occurs generally throughout the metastriate Ixodidae. 2,6-Dibromophenol, an artifact, also elicits the same sexual responses from the wood tick, but phenol and p-cresol do not.
