Efficacy of aggregation nano gel pheromone traps on the catchability of Rhynchophorus ferrugineus (Olivier) in Egypt

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