Cocoa mirids (274)
Pacific Pests, Pathogens and Weeds
Pacific Pests, Pathogens and Weeds

Summary

  • Narrow distribution. Indonesia, Malaysia, Papua New Guinea. On cocoa, and many other crops. Important pests.
  • Eggs laid in cocoa pods. Pseudodoniella has hump, Helopeltis has long antennae, and a spine on the back. Direct damage is done when mirids feed on young and mature pods, and shoots, and indirectly allowing entry of fungi, causing rots and dieback.
  • Cultural control: avoid Leucaena shade over cocoa in mirid areas, instead use coconuts to encourage ants that are antagonistic to mirids.
  • Chemical control: use synthetic pyrethroids (e.g., bifenthrin) or imidacloprid, treating 'hot spots' only, not the whole plantation..
