| Abstract |
On fields planted with Giza 89 and Giza 86 cotton varieties, the population fluctuation of the pink bollworm, Pectinophora gossypiella (Sound.), was studied using sex pheromone traps at Kafr El-Sheikh Governorate during 2002 and 2003 seasons. Also, the effect of prevailing weather factors (maximum temperature, minimum temperature, relative humidity and wind speed) on the flight activity of the insect and susceptibility of the larvae to insecticides were determined on Giza 89 and Giza 86 cotton fields.
Results indicated that the pink bollworm had three to four generations during two successive cotton seasons. Giza 89 cotton variety was more susceptible to infestation by P. gossypiella than Giza 86 variety. The population fluctuation of pink bollworm was affected significantly by the changes in weather factors on Giza 89 cotton variety, meanwhile, the effect was insignificant on the insect population on Giza 86 fields. The effect of wind speed was negative, whereas the effect of the other weather factors (relative humidity and temperature) was positive. Also, on Giza 86 cotton fields, the pink bollworm larvae were more susceptible to insecticide treatments.
