California Scientists Release Citrus Psyllid Predator

Tamarixia radiata
California scientists just released the Tamarixia radiata - a predator wasp that attacks our dreaded Asian citrus psyllid.

UC Riverside Executive Vice Chancellor Dallas Rabenstein and Mark Hoddle, the director of the Center for Invasive Species Research, released Tamarixia radiata – tiny, stingless parasitic wasps that lay eggs in ACP nymphs – in a citrus grove near the UCR Botanic Gardens. A total of 281 wasps (95 males and 186 females) were released.

Over the next several years, UCR and California Department of Agriculture Food and Agriculture (CDFA) scientists will raise thousands of Tamarixia for release throughout California. The Tamarixia larvae will eat the ACP nymphs, killing them, and emerge as adults about 12 days later. Adult female Tamarixia also eat other ACP nymphs, killing many in the process.
