Predator attacks citrus psyllid
POMONA (INT) The dreaded Asian citrus psyllid may have met its match.

Three million predator wasps have been released in urban parts of California to hunt down and kill the psyllid which carries an incurable citrus tree disease called Huanglongbing or HLB. The disease has been found in more than 600 backyard citrus trees this year in Southern California.

Researchers and students at Cal Poly Pomona use a dedicated greenhouse and research facility to rear tamarixia radiata, the tiny parasitic wasp.

So far, HLB has not been found in a California commercial grove, but has shown up in backyard citrus trees.
