One of the most common disease of palms is Red palm weevil (RPW, Rynchophorus Ferrugineus), which is one of the world’s major invasive pest species and is the single most destructive pest of some 40 palm species worldwide (e.g., date palm, coconut palm, and royal palm). The RPW pest was reported in Asia, Australia, Philippines, and Thailand as early as 1962. Since then, its expansion has covered near all countries in Asia, Middle East and the Mediterranean Rim. Recently, the RPW pest has also been reported in different areas of the American continent, being currently considered as a global pest.
The most challenging problem is that RPW is extremely difficult to detect in the early stages of an infestation because there are few externally-visible signs that the pest has taken over a tree: around 80 percent of the pest's life-cycle is hidden from view. For extremely tall species, an infestation in the crown of the tree is even harder to detect. Once an infestation has taken hold it is too late to save the tree.
Therefore, only the use of advanced technology and IoT are really effective methods to save the palms. In addition to the development of efficient early detection mechanism is a critical element of RPW pest management systems
RPW may exhibit the following symptoms:
Breaking of the trunk, or toppling of the palm crown.
Sensors are installed in each tree to record, memorize the acoustic behavior and analyzes data to find patterns and signs of Pests’ activity. Then they filter out the background noise and can also detect larvae as small as 1 cm long.
The accuracy of detection is 95%
