Abstract
Effect of mating disruption technique, at the
rate of 300 PB-Rope dispensers/feddanfor suppressing the
populationand percentage of infestationwith the pinkbollworm (PBW),Pectinophora gossypiella (Saunders) was
investigated in cotton fields at Assuit Governorate (Upper Egypt), throughout
the two successive cotton growing seasons 2013-2014. Catches of PBW moths in
the sex pheromone traps and the damage in green bolls were recordedin both treated and control fields. Data showed that
moth catches were highly suppressed (near 100%) in thetreated
field by installation of the dispensers during the 50% flowering growth stage.
In addition, % of average infestationin the cotton green
bolls was significantly decreased in the treated (1.51&0.89) compared with the controlfield
(20.54 &12.33%) in both seasons, respectively. A significant difference was
found in the average yield/feddan estimatedatthe
plot treated with pheromones (10.25 Kent.) compared with the control (6.37
Kent.). This study recommended using only one application of pheromone
dispenser during the flowering growth stage of the cotton plants is sufficient
to maintain the moth catches and infestation % in green bolls at the lowest
level
