Rhynchophorus palmarum (Linnaeus) - (South American palm weevil)
The weevil is found in Central and South America, where it attacks different types of palm trees, including coconut and oil palm. In 2012, it has been also reported from the southern U.S.A. R. palmarum breed in the upper (youngest) part of the palm trunk and the larvae often destroy the growing point, killing the tree. In addition, it can transmit the lethal red ring disease. Especially palms are vulnerable which are wounded near the upper trunk.
