Resumo
The range of the sex pheromone of Anocentor
nitens, 2,6-diclorofenol (2,6-DCP), was evaluated in an
olfactometer bioassay in order to get aid to use decoys of
this pheromone to control this tick. Twenty sexually active
males were release individually at 5 and 10 cm from control
rubber septa and treated with 50, 500 and 5000 ng of 2,6-DCP,
attractive females. At 5 cm distance the females were not
attractive as the responses of orientation and displacement
angles were similar to those observed to control rubber septa.
In both distance, the highest performances were observed
for the lowest concentrations of 2,6-DCP: percentages of
orientation were higher; the males were less tested; the
frequencies of angles between 0° and 10°, which indicate
attraction, were higher. Similar time of orientation was
observed to every 2,6-DCP concentration and higher than to
female and to control rubber septa. These results show that
2,6-DCP at 50 to 500 ng concentration is a remarkable attractant
for A. nitens and a potential candidate to be used in an
attractant and kill strategy for control this tick.
