The pheromones of insect pests affecting palms. Research under way and prospects. - (:unkn) unknown
Work being carried out jointly by CiradCP and INRA on the chemical substances, particularly pheromones, involved in the behaviour of certain oil palm pests, with a view either to improving observation and outbreak forecasting methods or to developing new control techniques, is described. The compounds in the pheromonal secretions of some leafeating Lepidoptera have been identified and determined. Formulations tested in the field have proved effective. Work on Curculionidae (Rhynchophorus and Metamasius) has resulted in the identification of aggregation pheromones, which have been synthesized and are currently being used in combination with the plant to trap adults and reduce the damage caused by these pests. Research is continuing with a view todeveloping an entirely synthetic attractant capable of trapping Rhynchophorus without the plant. Studies with Oryctes rhinoceros have helped to identify an active compound which is the main component of the aggregation pheromone and opens up new prospects for controlling the pest.
