Bagworms (Lepidoptera:Psychidae) are leaf eating caterpillars characterised by the possession of bag, built from pieces of dried plant materials such as leaves and small twigs ( Barlow,1982). Their outbreak are common in several states in Malaysia and have a significant economic impact on oil palm yield. According to Wood et al. (1973), 43% of yield decline over the next two year is caused by 50% of canopy damage. Hence, early detection of bagworm infestation becomes a critical part of reducing crop loss in oil palm plantations.
