To identify insect pest constraints on cocoa, develop farmer-centred technologies to manage the constraints and in so doing ensure that natural enemies are preserved to contribute to biodiversity.

Thrust activities
  • Identification
  • Biology
  • Life cycles
  • Temporal distribution
  • Damage and economic thresholds of the major & minor insect pests of cocoa
  • Development of pest control methods including chemical and biological control and integrated pest management programmes
  • Advice to farmers and other stakeholders on GAP
  • Nation-wide monitoring and early warning information on pest outbreaks
List of projects
  • Screening and field trials on Conventional Insecticides for the control of cocoa mirids.
  • Development of an Integrated Pest Management (IPM) strategy for stem borer control on cocoa by chemical and non-chemical methods
  • Exploring the use of natural enemies for the biological control of cocoa mealybugs Planococcoides njalensis (Laing) and Planococcus citri (Risso)
  • Assessing insect species associated with cocoa during establishment and developing control methods against pest species.
  • Integrated pest management programme in the cocoa industry in Ghana:
    • - The use of pheromones and other semio-chemicals
    • - The use of natural enemies
  • 6. Assessment of pesticide use patterns and residue levels in cocoa.
