The Biology, Ecology and Control of Vanapa oberthuri Pouill. Coleoptera; Curculionidae in Hoop Pine A raucaria Plantations in New Guinea.

Abstract

Vanapa oberthuri causes serious damage in plantations and also in some native stands of Araucaria cunninghamii. The adults fly and appear host specific. The life cycle lasts approximately six months. Galleries are produced in the inner bark by larval feeding. The effect is similar to that of 'ring-barking' and the tree dies in six months to one year. Successful attack appears to be associated with poor resin flow in the bark. Control is based on the early detection and removal of infested trees. Associated insects are discussed briefly.
