A bioassay method for the pheromone(s) of the bont tick Amblyomma hebraeum Koch.

ABSTRACT

A bioassay was developed which enabled the detection of the pheromones of the bont tick (Amblyomma hebraeum Koch) within 2 hours with a reproducibility of 82 +/- 13%. Dried, solvent-extracted ticks were glued onto the shaved backs of rabbits. Those ticks to which pheromone extract was subsequently applied strongly attracted females of the same species. In a 2-way choice test a cork disc impregnated with pheromone extract was even more attractive to female ticks than a treated dried tick.
