| Abstract | ||
| The present study was designed and conducted for the aim of using the micro capsulated sex pheromone as a part of integrated pest management (IPM) programs of the pink bollworm, Pectinophora gossypiella (Saund.). Two procedures were investigated in this line. In the first one, the micro capsulated formulation was experimented as partially, using pheromone early in the season in three consecutive applications followed by two insecticidal applications in Dakahlia Governorate. The second was a belt trial, in that procedure, the whole surface of the field was sprayed with micro capsulated pheromone three times early in the season, at two weeks intervals, and four times of spraying with the pheromone in the belt (the narrow strip of land to a width of 15-20 meters towards the inside of the field). The average percent of infested green balls by the pink bollworm were 1.72, 1.22 and 1.39% for the outlet during 1987, 1988 and 1989 seasons, respectively, while it was 0.29, 0.39 and 0.89% for the belt during the same seasons. On the other hand, the infestation percent of fields sprayed with insecticides were 2.51, 5.21 and 3.52. | ||
