  4. Vertical Distribution of CRB Larvae & Adults in Standing Dead CoconutTrankilidat, 25 Oct 2007

  5. CRB Breeding in Coconut Stumps

  6. CRB Extracted from Coconut Stumps at Trankilidat, 25 Oct 2007

  7. CRB Adults Attacking & Killing Young Coconut Palms

  8. Gun Beach / Faifai Beach

  9. 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 3rd instar, and we are started to see pupae. We can expect to see an outbreak of adults within 1-2 months.
