Abstract
Outbreaks of bagworms have been reported to cause severe defoliation to oil palm in Malaysia. The infestations provided an excellent example of the speed in which pest outbreak develop and spread under an extensive monoculture. A field study on a population of bagworm was made at oil palm plantation in Hutan Melintang Perak Malaysia from October 2005 to November 2005. Bagworms sampling was conducted at 14 days interval or twice per month. About 6 166 individuals bagworms collected and examined. Pteroma pendula was the most dominant species among all of bagworms recorded. It represented 98.38 6 066 individuals. The result shows that insect predators and parasitoids were responsible for causing mortality to the bagworms. Larvae of Callimerus arcufur were the most predator common encountered attacking bagworms. The population of bagworm was affected by 10th primary and secondary parasitoids. Three species of parasitoid were recorded; Dolichodenidea netasae was the most significant parasitoid of bagworm and this parasitoid commonly attacked by Pediobius imbrues Hyperparasitoid. Although several of the natural enemies were found affected the bagworms in the field and their resultant impact in controlling the bagworm population in the field is still far from desirable.
