Pantorhytes Control in Cacao Plantations.

Abstract

The cacao weevil borers (Pantorhytes spp.) I are now firmly established as major pests of cacao in the Territory of Papua and New Guinea. Five different species have so far been recorded from cacao and these occur in seven different districts. It is, however, only in New Britain, the Markham Valley and the Northern District of Papua that the incidence of the weevil is sufficiently high to cause severe damage. The known habits of the different species indicate that similar control measures should be adopted for each species.
