ABSTRACT Given the social importance related to the red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae), efforts are being made to develop new control methods, such as the deployment of trapping systems. In this work, the efficacy of a new black pyramidal trap design (Picusan) has been verified in comparison with white and black buckets. In addition, the attractant and synergistic effect of ethyl acetate (EtAc) at different release levels has been evaluated under… 

Improvements in Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae) Trapping Systems

Results obtained allow improved efficacy and may have an impact in the economic viability of trapping systems and, therefore, in integrated pest management programs.

Efficacy of bait free pheromone trap (ElectrapTM) for management of red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae)

The comparative efficiency of the service-less dry pheromone trap (ElectrapTM) against the traditional food baited traps, revealed that weevil captures in both the ElectrapTM and the food baiting traps were statistically similar.

Effects of Food Bait and Trap Type on Captures of Rhynchophorus palmarum (Coleoptera: Curculionidae) and Trap Bycatch in Southern California

In general, spiders, earwigs, and carabid beetles were most commonly recovered from Picusan traps, regardless of bait type, and no effects of bait and trap type were associated with bycatch species richness.

Measuring population fluctuation of jatropha stem-borer [Cophes notaticeps (Marshall)] in the Brazilian Cerrado using a new trap

The CPAC16 trap proved efficient in monitoring C. notaticeps through the use of a new trap, combined with different attractive lures and trap colors, and there were no significant differences among traps painted with different colors.

Pheromone trapping system for Rhynchophorus ferrugineus in Saudi Arabia: Optimization of trap contents and placement

Overall, date fruits, yeast and ethyl acetate together recorded the highest trap catches, and the differences in attraction of weevils due to various treatments have been analyzed and results are discussed.

Study of chromatic attraction of the red palm weevil, Rhynchophorus ferrugineus using bucket traps

The olfactory attractants used to bait traps are responsible for the female-biased captures, a phenomenon found to occur with all the colours tested, and useful information is provided for improving current management strategies against R. ferrugineus.

Identification of pheromone synergists for Rhynchophorus ferrugineus trapping systems from Phoenix canariensis palm volatiles.

The electroantennography response of the compounds identified was recorded, as well as the preliminary field response of several EAG-active compounds, and the so-called "palm esters" elicit the strongest EAG responses but performed poorly in the field.

Mass trapping technique in reducing Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae) damages in date palm groves in Tunisia

The carob moth, Ectomyelois ceratoniae (Zeller), (Lepidoptera: Pyralidae), is a cosmopolitan species widely distributed in different habitats worldwide. This pest is a well known by its severe

Red Palm Weevil Rhynchophorus ferrugineus (Coleoptera: Curculionidae): Global Invasion, Current Management Options, Challenges and Future Prospects

An overview of the global invasion of the red palm weevil, current management options, challenges and future prospects for its effective control are given.

Optimizing components of pheromone-baited trap for the management of red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae) in date palm agro-ecosystem

Sensitive olfactometer assays revealed that pheromone trapping alone cannot be relied upon to control RPW, but should be deployed with other management tactics.



Pheromone trapping protocols for the Asian palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae).

Synergism between ferrugineol and host palm volatiles was demonstrated and necessitates the inclusion of palm material in traps for maximum trapping efficacy, and pheromone-based mass-trapping of the Asian palm weevil throughou...

Development of a pheromone-based trapping system for Rhynchophorus palmarum (Coleoptera: Curculionidae)

An effective trap is developed that employs the newly identified major component of the male-produced aggregation pheromone, 2-methyl-5(E)-hepten-4-ol (rhynchophorol) for the capture of large weevils of tropical America.

Field efficacy of imidacloprid and Steinernema carpocapsae in a chitosan formulation against the red palm weevil Rhynchophorus ferrugineus (Coleoptera: Curculionidae) in Phoenix canariensis.

Both imidacloprid and S. carpocapsae in a chitosan formulation proved highly effective against R. ferrugineus in the field, and their efficacies did not significantly change when used in combination.

Effect of Bait Quantity and Trap Color on the Trapping Efficacy of the Pheromone Trap for the Red Palm Weevil, Rhynchophorus ferrugineus

Using a black pheromone trap containing 100 g of dates can significantly enhance R. ferrugineus control efforts, and can help considerably in reducing the red palm weevil's deleterious impact on date palm production in UAE.

Responses of Rhynchophorus ferrugineus adults to selected synthetic palm esters: electroantennographic studies and trap catches in an urban environment.

This study supports the application of the mass trapping implemented with synthetic palm esters as a potential tool for the management of RPW populations to protect ornamental palms in urban environments.


Good chemically-mediated field trapping of R. cruentatus was achieved with cruentol plus ethyl acetate (852 mg/d) and to a lesser degree with each of the following: (S)-(-)-ethyl lactate (release rate not determined; ND), ethyl isobutyrate (40mg/d, ethyl butyrate).

A review of the issues and management of the red palm weevil Rhynchophorus ferrugineus (Coleoptera: Rhynchophoridae) in coconut and date palm during the last one hundred years

The work done during the last 100 years on various aspects of RPW viz. life history, damage and symptoms of attack, seasonal activity, spatial distribution, host range, IPM and its main components, including trapping adult weevils and chemical control are reviewed.

Chemical ecology of the palm weevilRhynchophorus palmarum (L.) (Coleoptera: Curculionidae): Attraction to host plants and to a male-produced aggregation pheromone

It is proposed that a complex mix of ethanol, ethyl- acetate, pentane, hexanal, isolamyl-acetate, and/or isopentanol serve as a short-range orientation cue to fresh wounds on the plant and that additional host odors, attracting weevils from a distance, have still to be discovered.

The red palm weevil as an alien invasive: biology and the prospects for biological control as a component of IPM

The biogeography, basis of population outbreaks and current management tactics for the red palm weevil and related species are reviewed, and the potential of biological control to underpin the development of an IPM programme for it is assessed.
