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 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.

Perspectives for Synergic Blends of Attractive Sources in South American Palm Weevil Mass Trapping: Waiting for the Red Palm Weevil Brazil Invasion

“…Given that Rhynchophorus has a palm borer lifestyle, the damage is based on larvae survivorship in the host palm trunk coupled with late damage and infestation diagnosis [ 17 ]. Thus, understanding the insect’s behavior is important for the implementation of new control strategies, especially those derived from research on telemetry [ 37 ], semiochemical interference [ 38 , 39 , 40 , 41 ], new secondary metabolites and formulations [ 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ], early infestation detection [ 50 ], novel biopesticides [ 51 , 52 , 53 , 54 ], and natural enemies [ 55 , 56 ].…”

“…The best combination was in traps lured with ferrugineol + sugar beet juice + ethyl acetate + ethyl propionate than other chemical materials [ 95 ]. Improvements of the pheromones formulation technology, i.e., the use of pheromone in nanogels associated with dry funnel traps [ 44 ], disclose new opportunities.…”

Integrated Pest Management of Rhynchophorus ferrugineus Olivier: An Efficient Approach to Reduce Infestation in Date Palm Trees

“…In this study, two types of traps (traditional and dry funnel trap) were compared to check the capturing efficiency of RPW adults. It was observed that compared to normal traps the nano gel pheromone traps in field shown better catchability of RPW adults by 22.51 and 18.30% of total RPW adults captured in two consecutive periods respectively (El-Wahab et al, 2021). Another study was conducted to find out the food intake and developing phase of RPW larvae on three diets e.g., coconut cabbage, oil palm cabbage and sago stem while the proteins analysis…”

Stochastic Modelling of Red Palm Weevil Using Chemical Injection and Pheromone Traps

“…RPW as an invasive species is defined by its ability to invade, colonize and adapt to new agricultural areas worldwide [2]. The global movement of commercial goods helped spread the species of RPW, which was previously confined to areas of its initial discovery in India [3,4]. The insect is voracious in feeding, especially in the larval stage, which requires at least 60-90 days to complete its development and transfer to a pupal stage.…”
