Corn borer is one of the important pests on corn in Gorontalo province. Studies on natural enemies
(parasitoids and predators) of this pest in Gorontalo province has not been much studied. For the study of the
potential of local natural enemies need to be done. The purpose of this study is to see what kind of diversity,
composition, level parasitism, and predation. Data collection using the survey method in three districts in Gorontalo
Province and data were analyzed using the Shannon index. The results obtained for the type of local parasitoids
were found to consist of the order Diptera, Tachinidae family, order Hymenoptera, Ichneumonidae family, and the
order Hymenoptera, Chalcididae family, the composition of the predator 52 tails in Gorontalo districts; parasitoid 70
tails in Boalemo districts and 89 tails parasitoid in Pohuwato district. Furthermore parasitism rate of 53.3 % is higher
than the level of predation that is only 3.3%. One factor that supports the abundance of natural enemies is the
existing vegetation surrounding the corn crop.
