Review of the Coconut Leaf Miner and Tree Hopper Problems in Papua New Guinea, with a Report on their Incidence on Southern New Britain.

Abstract

A brief review is given of the coconut hispid leaf miner Promecotheca papuana Csiki and coconut tree hoppers (Segestidea spp., Eumossula gracilis Will. and Pseudonicraza szentia Will.) in Papua New Guinea. P. papuana is distributed throughout New Britain, Manus Island, Duke of York Islands, New Ireland District and the north-east of mainland New Guinea. However, serious outbreaks have occurred only on New Britain and the Duke of York and Manus Islands. It has never been of any importance on New Ireland and in the north-east of New Guinea. Tree hoppers are widely distributed in Papua New Guinea and their status as a pest varies from place to place.
