Potentials of Using the Pheromone Trap for Monitoring and Controlling the Bagworm, Metisa plana Wlk (Lepidoptera: Psychidae) on Young Oil Palm in a Smallholder Plantation

This study was carried out to investigate the potentials of using the pheromone trap for monitoring and controlling the bagworm, Metisa plana Wlk (Lepidoptera: Psychidae) on young oil palm in a smallholder plantation in southern Perak, Malaysia. Three types (Delta, Open-Delta, and Vane) of traps were evaluated with receptive virgin females as the pheromone sources. The Vane trap appeared to be most effective. Increase in pheromone sources resulted in more trap catches. The sticky Vane traps with receptive females showed potentials for mass trapping the bagworm, which resulted in reduced field population of bagworms.
