The present work was conducted to evaluate the effect of eight insecticides against red palm weevil (RPW), Rhynchophorus ferrugineus under laboratory and field conditions.  The insecticides were studied namely, Chlorpyrifos, Diazinon, Ethion, Fenitrothion, Fipronil, Methomyl, Phenthate and Profenofos. Under laboratory condition results showed that, Chlorpyrifos was the most effective insecticide against the egg stage of RPW, while Fipronil was the most effective one against larval and pupal stage, and Methomyl recorded the highest effect against the adult stages (♀, ♂). At field condition Data revealed that, at the concentration of 3ml/L, all level of the tested insecticides caused 100% recovery expect Methomyl which reached 90% recovery only. Using 2ml/L of the tested insecticides revealed 100% recovery with Fipronil, and 90% with Chlorpyrifos and Phenthoate, while it was 80% with Ethion, Fenitrothion and Profenofos. Diazinon and Methomyl revealed only 60 and 50% recovery, respectively. It worth mentioning that Fipronil seams as the most effective one followed by Chlorpyrifos and Phenthoate.
