BACKGROUND: The red palm weevil,Rhynchophorus ferrugineus (Olivier), is a phytophagous insect that feeds on soft succulent
tissues of most palm species and is considered the main palm pest in the Middle East and the Mediterranean Basin. The aim of
this study was to test the efficacy of imidacloprid oil dispersion (OD) as a drench in preventive and curative treatments against
R. ferrugineus inPhoenix canariensis, Washingtonia robusta, Washingtonia filiferaandTrachycarpus fortunei.
RESULTS: Levels of infestation were highest in P. canariensis. There was no infestation in W. filifera. Mean efficacies of 100 and
94% were obtained in preventive and curative treatments respectively. High efficacies in preventive treatments (mean 95.4%)
lasted for up to 45 days after application.
CONCLUSION: The high efficacies and persistence of imidacloprid OD applied as a drench in young palms show the potential of
this product for the management ofR. ferrugineus [-]
