The objective of the present study was to evaluate the behavior of P. gossypiella males
captured with pheromone-baited traps in cotton field. Three experiments were done
during the 2001-02 and 2002-03 growing seasons using the Delta Opal cotton cultivar.
The first experiment was related to the insect population captured during the crop cycle
by of two commercially available Delta type traps, the second experiment was conducted
to evaluate the efficiency of traps in capturing P. gossypiellamales and, the third experiment
assessed the nocturnal circadian rhythm. It was realized a descriptive analysis of the data
collected to first and third experiment. Used in this second experiment consisted of
comparing randomly selected groups, and the means were compared by t-test, the
significance level was set at 5 %, and, the canonical correlation analysis was performed.
The Delta pheromone trap was more efficient in capturing P. gossypiella than was the PET
pheromone trap. Nocturnal activity peaks were found to be related with the time of year
and it occurs between 11:00 p.m. and 2:00 a.m.
