ABSTRACT

The pink bollworm Pectinophora gossypiella (Saunders) have the ability to camouflage themselves with in rosette flowers and bolls and can reduce cotton yield up to 30%. It is considered to be a critically important pest of cotton all over the world. Field trials were conducted in different districts; Vehari, Rajanpur, and Mianwali, of Punjab-Pakistan during 2017 to evaluate efficacy of synthetic sex pheromone [ZZ/ZE-7, 11-Hexadecadiene-1-yl-Acetate] impregnated ropes by using PB rope L dispensers at @ 100/acre, at first pin square stage to cause mating disruption. Performance comparison of control fields compared to PB rope treated fields was assessed throughout cropping period in different ecological zones using Analysis of Variance and Tukey multiple comparison means tests indicated a 95 % reduction in moth trap catches from July to October, in all the tested ecological zones. The percentage flower and boll damage in the control fields was significantly higher than those in the PB ropes fields. There were no significant differences in moth catches, rosette flower percentage or left over boll damage %age among different Tehsils and varieties. However significant differences were observed in boll damages among Tehsils and varieties. Our studies showed significantly lower damage levels in left over bolls at the time of harvest and higher overall cotton yield in PB rope plots compared with control plots.
