A trap was designed to allow red palm weevil adults to pass through it so that they come out contaminated with a high density of the fungus conidia for spreading them amongst the red palm weevil population in date palm plantations. A fungus inoculum containing 10% conidia was prepared and used in the trap. An adult was contaminated with 9.53x107 conidia per a tape visit with a lethal time of 8.25 days. Field trials were carried out using 20 traps in 3 date palm plantations in the period from April 2006 to May 2007 in the Northern Region of United Arab Emirates. Efficacy of the trap was evaluated by assessing the monthly mortality caused with the fungus in the adult population. In the last two months, mortality of adults caused by the fungus in the field population ranged 41.2-51.3% compared with 4.8-4.9% in the control. Results showed that the trap is effective for spreading the fungus Beauveria bassiana among Rhynchophorus ferrugineus population.
