- Abstract
Cocoa Pod Borer (CPB) Conopomorpha cramerella Snellen is the primary cause of significant yield loss up to 80- 90% for smallholders. It is hard to control the pest because most of their lives are in cacao pods, which makes them protected from natural enemies and insecticide applications. This study was conducted to obtain CPB control strategies that can be applied by farmers and to increase their cocoa productions. We observed CPB infestation, the population of its natural enemies Cocoa Black Ant (CBA) Dolichoderus thoracicus along Cocoa Mealybugs (CM) Exallomochlus hispidus, and the cocoa canopy at 10 cocoa farms from March 2018 to June 2019. Mutual association was found between the cocoa black ants and cocoa mealybugs in 62% of the cocoa trees that grown under shade trees. They were found nesting on coconut (Cocos nucifera), soursop (Annona muricata), kapok (Ceiba pentandra), and jackfruit (Artocarpus heterphyllus), that grow around or mixed with cocoa trees inside the farm areas. Most of the cocoa trees had dieback because they did not apply fertilizer and, in some areas, there were no shade trees. In Langkat District, the cocoa black ants and cocoa mealybug symbiosis and populations have grown naturally. Thus, it is enough to provide empty artificial nests of ants as a strategy to increase their populations in the cocoa farms.
