January 2011. Pandanus cultivars in Madolenihmw, Pohnpei, FSM are not growing well on the acid soils. Fruits are rotting before maturity as are the trunks, leaves are yellowing, and there is an insect boring into them.

A closer inspection found a heavy infestation of a larvae tunneling inside the foliage (see photos).

The larvae look like Coxina. Pestnet members were asked if they had seen similar damage elsewhere.
