Résumé : Oryctes rhinoceros (Coleoptera, Scarabaeidae, Dynastinae) is one of the most serious pests in young oil palm and coconut plantings. Adults mine galleries in young fronds. Such attacks retard the development of young palms and sometimes kill them. The insect develops in rotting wood and old stems left on the ground during land preparation. Replantings to replace old oil palm plantings are propitious to pest development. Young palms are protected by repeated applications of insecticide granules, which are costly and not without risks for the environment (pollution of the water table). Manual collection calls for frequent rounds and is therefore labour-intensive. The discovery and the use of the aggregation pheromone ethyl 4-methyloctanoate (E4MO) as an attractant to capture the pest offer new prospects for its control by mass trapping and the reduction of populations. The results of a study testing increasing doses of E4MO using different dispensers are given. The trial was conducted in North Sumatra (Indonesia) in an oil palm replanting.
