Field experiments were carried out at the Experimental Farm; Faculty of Agriculture, Saba Basha, Alex. University during two successive growing seasons . 1999 and 2000 to evaluate the effect of three slow release pink ballworm pheromone formulations; Rope-PBW, Selibate and last flight , and / or profenofos (curacron) insecticide in special regimes against pink bollworm, pectinophora gossypiella (saund) . The percent infsttation, phonological characters of cotton plants and fiber quality were recorded. The experiments showed the following results. 1- The pheromone formulations applied followed by two applications of the insecticide gave good control of the pink bollworms as compared with the insecticide in four applications according to a regular program. 2- The highest reduction in the cotton bolls infestation was induced by Regime( T1) [ Rope- PBW/ curacron/ selibate/ curacron] followed by Regime ( T2) [ Last flight! Curacron/ selibate/ Curacron] and Regime( T3) [ Selibate / Curacron / Last flight / Curacron). The least reduction in bollwoms infestation was accrued 'in the insecticide treatment. Regarding to the cotton varieties, it is obvious that Cultivator Giza88 is superior using regime (T1) [Rope- PBW/ Curacron/selibate/ curacron].Throughout 1999 and 2000 seasons respectively.
