El comportamiento de pectinophora gossypiella (saunders, 1844) (lepidoptera: gelechiidae) (oruga rosada) machos capturadas con trampas de feromona sintética en campos de algodón
The objective of the present study was to evaluate the behavior of P. gossypiella malescaptured with pheromone-baited traps in cotton field. Three experiments were doneduring the 2001-02 and 2002-03 growing seasons using the Delta Opal cotton cultivar.The first experiment was related to the insect p...

| Resumo: | The objective of the present study was to evaluate the behavior of P. gossypiella malescaptured with pheromone-baited traps in cotton field. Three experiments were doneduring 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 cycleby of two commercially available Delta type traps, the second experiment was conductedto evaluate the efficiency of traps in capturing P. gossypiellamales and, the third experimentassessed the nocturnal circadian rhythm. It was realized a descriptive analysis of the datacollected to first and third experiment. Used in this second experiment consisted ofcomparing randomly selected groups, and the means were compared by t-test, thesignificance 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 PETpheromone trap. Nocturnal activity peaks were found to be related with the time of yearand it occurs between 11:00 p.m. and 2:00 a.m. |
