Abstract

The beetle pests Scapanes australis, Oryctes rhinocerous and Rhyncophorus bilineatus have been major constraints to coconut production in the Islands region of Papua New Guinea for the last 30 years. Efficient synthetic attractants able to lure and trap all three beetles have been developed. This paper describes several trap designs developed at the Cocoa and Coconut Research Institute and the results obtained for their trapping efficiency in the laboratory and the field. A modification of the “Titus Bucket” trap increased the number of R. bilineatus caught threefold and of female Scapanes twofold. PVC pipe traps caught more Scapanes than the modified “Titus Bucket” trap.

Abstract

Oryctes rhinoceros (Scarabaeidae, Dynastinae) trapping is possible with the pheromone (ethyl 4-methyloctanoate) as the attractant. This article describes a new type of trap that functions without insecticides or water, and can remain in place for several months without any particular maintenance so long as the attractant does not run out. As it is 2 m tall, it offers the advantage of having the silhouette of a palm stem, which is visually attractive to this insect
