It would be best to wait at least 2 years, before replanting. Normal generation time in the lab is 9 months to 1 year, but this may be extended if grubs are malnourished. Adults will attack banana and sugarcane for sap, and larvae do well on a range of substrates with high organic content. It was thought that the beetles ate Pandanus after killing all of the coconut trees on some of the smaller islands in Palau during the original invasion (reported in Gressitt’s monograph). Can the beetles re-infest Fanna by flying one mile from Sonsorol Island?.How long will it take the immature beetles to complete their life cycle and die out?.If there are alternate food sources for the beetles, what are they?.If there are no more coconut trees on Fanna, will the beetles eventually die out, or do they have an alternate food source? If no alternate food source, then the few remaining coconut trees could be cut down, and the immature beetles would complete their life cycle and starve.The Lieutenant Governor of Sonsorol has asked for advice. Fanna is located over 200 miles southwest of the main Palau archipelago, and is part of Sonsorol State. Coconut trees on the small and remote island of Fanna, Palau have been devastated by the coconut rhinoceros beetle: only a few trees remain.
