Population fluctuation of the red palm weevil, Rhynchophorus ferrugineus (RPW)was studied using the aggregation pheromone traps, during2012-2013 in Rashid district. Fortnightly catches  of  the  RPW showed that  RPW existed all over the year and there are four peaks during the tested year 2012-2013, the mean of the total captured adults at dults/ trap) recorded at 15^th Sep. 2013 it is the last peak. The results showed that there was non-significant positive correlation between mean daily temperature and the population abundance of RPW, while there was a significant negative correlation between the means of daily relative humidity and the population abundance of the RPW adults during the tested year. The numbers of females attracted to aggregation pheromone traps were generally twice as that of males. The sex ratios of male to female were 33.4: 66.6 during the tested year 2012/2013. The results showed that tthe beginning of December 2012 was  6.40 adults/trap then it decreased gradually to record the lowest average of captured RPW adults (2.30 adults/trap) at 15^th  Jan. 2013, and it fluctuated to record four peaks  the first (17.40 adults/trap) recorded at 15^th April 2013, the second peak (12.80 adults/trap) recorded at 30^th May 2013, the third and the highest peak  (20.60 adults/trap) recorded at 15^th July and the fourth peak (10.40 ahe captured population of weevils in Eastern direction was the highest followed by South, center, and the least captured numbers recorded in West and North directions.
