Photos: Asian citrus psyllid has an enemy

The Asian citrus psyllid (ACP) in California has a new enemy. Researchers from the University of California, Riverside have imported an invasive pest from Pakistan that preys solely on the ACP. A parasitic wasp called Tamarixia radiate has been released in southern California to help slow the spread of the ACP. A second kind of parasitic wasp may soon be released, pending U.S. Department of Agricutlure approval.
