Abstract
The red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) is the most serious pest of Canary Island date palms (Phoenix canariensis Hort. ex Chabaud) and date palms (Phoenix dactylifera L.). Early infestations of this invasive weevil are difficult to detect under field conditions. The adults are very elusive and not visible inside the dense frond of the palms. Efficient methods for detecting this pest are needed for its successful management under field conditions and in particular at ports of entry to avoid its' spreading via infested imported palms. The present study evaluated the ability of Rottweiler and Golden Retriever dogs (Canis familiaris L.) to detect Canary Island palms that were baited with RPW adults or larvae under field conditions. During these experiments, the dogs successfully detected 78% of the baits hidden in the crown of the palms. These encouraging results need to be confirmed by evaluation of the performance of sniffing dogs in detection of naturally infested palms of different species.
