“…In Spain Sansano et al (2008) found that during one year, the average number of trapped female was 2.5 times higher than the male's one. El-Sebay et al (2010) observed that number of RPW female attracted to aggregation pheromone traps was considerable high than males during two successive years (2008 and 2009).…”

Field experiments were carried out in the reclaimed land east of Cairo-Alexandria Desert Road, Village of Wardan, Giza Governorate, Egypt, to evaluate the impact of using nano-gels pheromone for the first time on the attraction of the RPW adults by pheromone traps compared to the control which is normal pheromone during two successive seasons in 2018 and 2019. Also, this study aimed to compare the efficacy of two types of trap, traditional trap (type 1) and dry funnel trap (type 2) in capturing of RPW adults. Results revealed that the nano gel pheromone traps attracted significantly more adults with an average of (4.26 and 3.56) adults/trap and total of (55.33 and 46.33) adults/trap compared to control with an average (2.69 and 2.46) and total of (35.00 and 32.00) adults/trap for the two seasons 2018 and 2019 respectively. Results indicated that the use of nano gel pheromone for the first time in field improved the trap catchability to RPW adults by 22.51 and 18.30% of total number of RPW adults captured throw out the two successive seasons respectively. In addition, there was no significant difference between the total numbers of RPW adults collected by the two tested type of traps over the two successive seasons. Furthermore, the sex ratio between males and females of total collected RPW adults found to be1: 1.43 and 1: 1.94 at 2018 and 2019 respectively.

The Seasonal population fluctuation of red palm weevil, Rhynchophorus ferrugineus Olivier (RPW) (male and females) was estimated during two successive seasons (2017/2018 and 2018/2019) by using aggregation pheromone traps in date palm orchards located at Newly Salhea district, El-Sharkia Governorate, Egypt. The results obtained during the two successive seasons of study showed that, the average number of insects per year was different. Season, 2018/2019 was highest more than season, 2017/2018.The highest number adult stage of red palm weevil, RPW captured by pheromone traps was recorded in April. Four peaks of swarming activity on date palm trees throughout the two seasons April, November, March and May, respectively. In both seasons, the first peak occurred during April, while the second one occurred during November. Number of attracted female was considerable high than attracted males. Where the sex rstio % for male percentages were 1: 1.85% for male and female, respectively in season 2017/2018 while in season, 2018/2019 the male percentages were 1: 1.75 % for male and female, respectively. These results also revealed that effect of weather factors on capturing both simple correlation and regression values were insignificant positive effects for maximum, temperature and wind velocity on number of captured adults of RPW in the two seasons, while it was insignificant negative effects for mini Temp. , max, Mini relative humidity and the explained variance percentage (E.v. %) for the three weather factors on the number of captured adult was 7.88%.
