The influence of irrigation techniques on date palm infestation by the red palm weevil

This study investigates the impact of different irrigation methods on the infestation levels of the red palm weevil (RPW) in date palms. Results indicate that palms irrigated with bubbler systems experienced significantly higher infestation rates compared to those using surface drip and subsurface irrigation methods, with the latter showing no signs of infestation. Severe infestations in bubbler-irrigated palms necessitated the removal of three infested trees, while mildly infested palms under surface drip irrigation were successfully treated and fully recovered. The findings align with previous research, highlighting that flood irrigation leads to higher infestation rates, with 89% of infested palms in flood-irrigated areas compared to only 10% in drip-irrigated zones. The study emphasizes the importance of selecting appropriate irrigation techniques, such as surface drip and advanced subsurface systems utilizing ultra-low energy dripper technology, to enhance the health and productivity of date palm plantations while mitigating the risk of RPW infestation. Further empirical research is recommended to validate these findings.
