A Survey on Detection of Red Palm Weevil Inside Palm Trees: Challenges and Applications

Red Palm Weevil (RPW), is a lethal pest affecting different species of palm trees especially date palms. It is also reported to be a worldwide issue as a result of attacking more than thirty-five countries. Palms are never in safe hands once affected by RPW, unless it is detected in the early stages of infection. Although many endeavors and studies have been made to deal with this pest, none of them were successful enough to discuss a method that detects RPW in its early stages. This survey provides an overview of the detection methods used. Furthermore, it introduces a new hybrid technique for RPW detection in its early stages. The technique is based on combining thermal and hyperspectral imaging (HSI) as well as applying different image processing and deep learning techniques to get the optimum results in this field so far after applying enhancements to these methods.
