The objective of this research was to study the natural enemies and its mode of action during the development of Oncideres impluviata larvae. Branches of Bracatinga (Mimosa scabrella Benth.) attacked by twig girdler were periodically collected during 1984/85, in Almirante Tamandare- Paraná. Field collected larvae had their cycle completed in laboratory inside test tubes containing moistened saw dust of Bracatinga. Larvae when collected had recorded its location of branch besides collection date instar. The efficiency of natural enemies was evaluated as well as the time they were active. The observations conducted led to the conclusion that predatory action was more efficient than parasitism which had a tendency to decrease whereas the predatory action increased with larva development. The most frequent parasite was cenocoelius sp. (Hym.; Braconidae) and among predators, Cregya difformis (Col.; Cleridae) and Liothrips sp. (This.; Phloeothripidae).
