Abstract
Oligonychus iseilemae is one of the spider mite pests on the coconut palm foliage. This mite infests the ad-axial surface of the leaflets in colonies and the feeding results in the drying of the affected foliage. Natural predator complex of 0. iseilemae comprised six species of spider. A. (A.) paraaerialis, A. (T.) eucalypticus. Cunaxa selirostris and Agistemus sp. are the major mite predators. Insect predators comprised Coccinellidae, Cecidomyiidae, Chrysopidae and Thripidae. Clubionid spiders are also dominant predators on this mite pest. The biology, predator-potential, seasonal occurrence and predator-prey ratio of the important predators were discussed.
