Seasonal abundance and population trends of red palm weevil, rhynchophorus ferrugineus oliver (coleoptera curculioinidae).

The Seasonal abundance and population trends of red palm weevil, Rhynchophorus ferrugineus Oliver (male and females ) population was estimated during two successive years (2008 and 2009) by using aggregation pheromone traps in date palm orchards located at Arement, Giza Governorate . The results obtained during the two years of study have dearly showed that adult stage of red palm weevil, Rhynchophorus ferrugineus has two peaks of swarming activity on date palm trees throughout the year. In both years, the first peak occurred during March ,while the second one occurred during October. Number of attracted female was considerable high than attracted males. Correlation analysis indicated there was insignificantly positive correlation between trap catches and infestation date palm .
