Abstract
Surveys were conducted to identify the natural enemies of the oil palm leafminer, Coelaenomenodera lameensis Berti and Mariau (Coleoptera: Chrysomelidae). Different developmental stages were recovered from infested leaflets and reared for the emergence of parasitoids. Four parasitoids all belonging to the order Hymenoptera and family Eulophidae were identified. They were Neochrysocharis species, Chrysocharis species, Pleurotroppopsis species and Apleurotropis species. Parasitism on C. lameensis developmental stages by the parasitoids was 13.51%. Predatory ant survey was based on the presence of the nests on the oil palm. Oecophylla species, Crematogaster species and Tetramorium species were observed to be the predatory ants of the oil palm leafminer on the plots. Entomopatho.genic studies were based on the collection of dead and/or dying C. lameensis stages for further culturing and identification. The entomopathogenic fungi identified in this study was the Zygomorpha Syncephalastrum racemosum Cohn belonging to the order Mucorales
