The present work was carried out at El-Katta village to evaluate the efficiency of six synthetic insecticides (Pyriban^®, keiton^®, Egycron, Fenthion^®, Fury^®, and Regent^®) and two bio-insecticide (Biovar^® (Beauveria bassiana) and Avermectin^® (emamectin benzoate)).  Insecticide solutions were injected into three holes against the immature stages of Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae). Three concentrations of each tested insecticides (0.3%, 0.6 and 0.9%) were used. The insecticides were applied at rate of one liter per tree. The numbers of recovery palm trees were investigated every week and recorded after forty five days from treatment. The obtained results showed that the most effective insecticide was Pyriban^® and Keiton^® (62.5%), followed by Egycron^® (58.3%), Fenthion^® (37.5%), Fury^® (29%), and Reagent^® (25%). The bioagents were less effective than synthetic insecticides; Biovar^® (12.5%) and Avermectin^® (4.1%) at 0.3% concentration.
