Abstract

Altogether about 920 species of insects recorded from Eucalyptus worldwide, about six species are gall insects. Of these, Leptocybe invasa, is a major nursery pest of Eucalyptus, exclusively responsible for gall formation in seedlings and saplings, including coppice shoots. The insect has threatened Eucalyptus propagation in nursery stage. The present paper has reviewed succinctly the insect pests of Eucalyptus with special emphasis on gall insect, Leptocybe invasa Fisher & LaSalle (Hymenoptera : Eulophidae), its seasonal occurrence, nature of damage, host plants and description of gall insect, developmental stages of gall, natural enemies and management. The paper has highlighted the need for long term strategies to combat against this severe pest to prevent its spread.
