| Abstract |
The present investigation was directed to study the occurrence and seasonal abundance of the pink bollworm Pectinophora gossypilla (Saunders) (PBVV) in cotton fields during 2003 and 2004. The effect of prevailing climatic factors on flight activity of male moths was also studied. Flight activity studies using pheromone traps during two successive cotton seasons indicated that P. gossypiella had three generations with three sharp peaks on cotton during the period started early in May and extended till the last week of September. The combined effect of the prevailing temperature and relative humidity were responsible for 8.3 % and 36.7 % at Kafr 'El-Sheikh Governorate of the changes in male moths population during 2003 and 2004, mean while, Dakahlia Governorate responsible for 11.1 and 40.5% of the changes of the population male moths respectively. Larval population and boll infestation started during early July and increased progressively till the end of the season.
