Abstract
Cocoa Pod Borer (CPB), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae), is an economic important pest of cocoa. The CPB larvae are able to reduce bean quality and production. Various methods have been developed to manage and control the pest effectively. Continues study on the pest however still relevant to get more information so that control methods can be improved further more. It is handy in precision agriculture to have foreknowledge of infestation pattern on the farm area. Such information is crucial in devising a management strategy that precise and cost effective to control the pest. Hence a study was conducted for the period of Nov 2017 to Mar 2020 on one hectare farmers cocoa field in Sin Onn, Tawau, Sabah. The cocoa field was divided into 60 small plots and Global Positioning System (GPS) coordinates were recorded. On each small plot, CPB infestations which are the Average Damage Severity Index (ADSI), larva entry and exit hole, and wet bean weight were recorded. The data obtained were interpolated into Geographic Information Systems (GIS) mapping to visually observing the spatial and temporal distribution pattern. The GIS map information of CPB infestation was discussed on its important for formulating a management strategy to control the pest in precision agriculture of cocoa.
