The efficacy of the aggregation pheromone of Rhynchosphorus palmarum (L.), 2(E)-6-methyl-2-hepten-4-ol, mixed with insecticide to capture adults of this pest on oil palm tree Elaeis guineensis was evaluated. Cuttings into the trunk of oil palm trees attacked by Rhadinaphelenchus cocophilus Cobb., the agent of red ring disease, were sprayed with Furadan 350 SC plus 3 ml 2(E)-6-methyl-2-hepten-4-ol. Another group of plants was treated with insecticide only. The capture of R. palmarum on oil palm trees treated with pheromone plus insecticide was 65 to 89% greater than those treated with insecticide only.
