Abstract
In Egypt, the pink boll worm (PBW), Pectinophora gossypiella (Saund.) (Lepidoptera: Gelechiidae) is a serious mid- and late-season cotton pest that causes severe damage. Trials included; releasing of the egg parasitoid, Trichogramma evanescens (West.) (Hymenoptera: Trichgramatidae) and/or mass-trapping of the male moths of PBW compared with the conventional insecticide applications; for controlling the pest were carried out in the cotton fields in Menoufia Governorate, Egypt during the two cotton growing seasons of 2013 and 2014 to compare the efficiency of different methods against the pest. Nine parasitoid releases were undertaken in each season. Mass-trapping of the PBW moths showed the highest reduction in the green bolls’ infestation, followed by releases of the parasitoid alone, while the insecticide applications recorded the highest infestation rates during the two seasons. Seasonal reduction percentages in green boll infestation at the parasitoid release and the mass-trapping plots attained (30.65 and 43.1% in season, 2013 and 37.66 and 49.77% in season, 2014), respectively, opposed to (37.78 and 47.30%) at the insecticide application plot. Therefore, integrated pest control programs are highly recommended against the cotton pests, especially the boll worms, in Egypt.
