Abstract:
The red palm weevil (RPW) is a palm borer insect that develops within the soft tissues of the trunk and crown, eventually leading to tree death. Early detection of RPW infestation is crucial. The RPW larvae developing inside the palm and direct visual detection of the infestation is quite difficult. The hypothesis was that the tunneling insects destroy the vascular system of the palm and create local conditions of water stress. The goal of this study was to examine the ability to detect infected trees using thermal images. By measurements, imaging and analyzing of infected and uninfected trees over multi-year experiments in quarantine and commercial orchards, results partially showed that the RPW creates water stress and affects canopy temperature. Analysis of aerial thermal image above date palm plantation successfully detected infected trees.
