title: Humidity effects on response ofArgas persicus (Oken) to guanine, an assembly pheromone of ticks.
abstract: The assembly behavior of the tickArgas persicus Oken in response to guanine has been found to be humidity dependent. Nymphal and adult maleA. persicus assemble on guanine-treated paper disks only at low relative humidities (25 ± 5%). Exposure of the ticks to high relative humidities (85 ± 5%) results in a gradual induction of a negative response to the pheromone.
