The weaver ant, Oecophylla smaragdina (Fabricius), inhibits infestation of the mahogany plant by the shoot borer, Hypsipyla robusta (Moore), a major pest of mahoganies worldwide. Host plant species of the weaver ant were identified in a survey covering four diverse vegetation types in Central West Peninsular Malaysia. Of three favored host plant species, Morinda citrifolia (Linnaeus) had a significantly higher abundance of the ant than the other two species. Inter-planting M. citrifolia with mahogany may enhance the introduction and establishment of weaver ant colonies for control of the mahogany shoot borer.


Species 1: Hymenoptera Formicidae Oecophylla smaragdina (weaver ant, green tree ant)
Species 2: Lepidoptera Pyralidae Hypsipyla robusta (mahogany shoot borer, cedar shoot moth)
Species 3: Rubiales Rubiaceae Morinda citrifolia (Noni, Mengkudu)
