Diaprepes root weevils have been on the move in California in at least one San Diego County nursery and where new construction brings in a large number of specimen trees for landscaping purposes.


State agriculture officials are asking California landscapers to look out for the Diaprepes root weevil, which has traveled to the state in nursery-grown tree stock.

The dime-sized weevils were found in early December in a commercial nursery and surrounding neighborhood in San Diego, Calif. Landscape professionals are urged to keep a lookout for the colorful bug, which is hard to see because it lives on the undersides of leaves.

The nursery and neighborhood are undergoing treatments with Sevin insecticide to contain the insect, which has cost farmers and growers hundreds of millions in damage in Florida and Texas.

If you see the weevil, please call the number below.

Additional infestations are possible where new construction brings in a large number of specimen trees for landscaping purposes.

Diaprepes root weevils are native to the Caribbean, have generally infested Florida and have also infested a part of Texas. Adult weevils feed on the leaves of plants and their larvae plunge underground and feed on plant roots. Left unchecked, the pest could damage urban and rural landscaping, the nursery industry, and significant portions of California?EUR??,,????'?????<
