Another palm tree infested with red palm weevil

Officials have confirmed that the red palm weevil is not confined to a single palm tree in Laguna Beach, according to a story in the Daily Pilot. Just blocks from the first infested tree, another Canary Islands date palm is being killed by red palm weevil.

UC Riverside Cooperative Extension entomologist Mark Hoddle said the crown of the second infested palm has dropped off, and the top of the trunk is ringed with a 'halo' of palm fronds.

"The trunk of the palm has been heavily damaged internally by feeding red palm weevils. The central portion of the trunk now contains a highly fermented and very wet 'mash' of plant material," the story quoted Hoddle.

The dying tree contained portions of at least nine dead adult weevils, one live adult and seven empty pupal cases.

It is now likely that additional palms in North Laguna are infested with this destructive pest, the story said.

CDFA, the Orange County Ag Commissioner, USDA and UC Cooperative Extension are hosting the first of several informational meetings from 10 a.m. to 12 noon Friday, Nov. 5, in the Laguna Beach City Council Chambers, 505 Forest Ave. At the meeting, experts will inform local government officials, arborists, public works officials, landscapers and pest control advisers about the current red palm weevil situation and how to identify the pest and its feeding damage.

Future meetings will target other industry members and the public.

Details about the meeting and more information are on the UC Riverside Center for Invasive Species Research blog.

Southern California Public Radio's Madeline Brand interviewed Hoddle about red palm weevil for a story broadcast last Friday.
