26. CRB Adults Attacking & Killing Young Coconut Palms

34. Gun Beach / Faifai Beach

37. Conclusions Decaying coconut stumps are an excellent breeding site for CRB. Necessitates spot treatment with persistent insecticide. Young coconut palms (1-4 yrs. Old) are being killed by CRB adult feeding activity. We do not yet have confirmation that CRB is breeding at Faifai Beach. However, numerous standing, dead coconuts should be inspected & removed ASAP. (Same with Gun Beach). Most larvae at Trankilidot are 3 rd instar, and we are started to see pupae. We can expect to see an outbreak of adults within 1-2 months.
