Narrow distribution. Indonesia, Papua New Guinea, Philippines, Solomon Islands. On cocoa and several commercial forest trees, e.g., Eucalyptus and Terminalia.
Eggs (2 mm) laid singly in cracks in trunk and branches; larvae bore into tree (3-9 months), then pupate; adults (1.5 mm long) without wings, feed on flowers, bark, surface of pods.
Larvae cause dieback, and allow entry of e.g., Phytophthora (causing cankers) and termites.
Cultural control: handpick in middle of day when weevils come down from the top of the canopy; inspect for tunnels, using wire to kill larvae; use coconuts for shade (possibly, ants reduce weevil numbers).
Chemical control: mix acephate, white oil, metalaxyl (or phosphorus acid) and brush into holes; repeat after 2 weeks.
