Abstract

The red palm weevil (RPW), Rhynchophorus ferrugineus is a worldwide serious and destructive insect pest for date palm trees. The present work was carried out to evaluate different methods in the control of  red palm weevil infesting palm trees. The obtained results of the experiments revealed that the five holes method of injection and aluminum phosphide tablets 57 % is very safe to the palm trees 3-6 years old recording 80-90 mortality %. Furthermore, low pressurepump increases the efficacy of the injection process for infested date palms above 7 years old. The experiments revealed that the manual method as only one hole of injection gave reduction percentages ranging between 30-40%. From theobtained results, it could be reported that the recommendation injection method and the use of aluminum phosphide tablets are safer for palms above 3 years oldexcept the cases of the infested head of palms, while pressure pump is a safe method except for infestation of head and top date palm 7 years old.
