The first release this week in Riverside of Tamarixia radiata, a tiny wasp from the Punjab that is a natural enemy of Asian citrus psyllid, was picked by several news outlets, including the Riverside Press-Enterprise, the Porterville Recorder and the Desert Sun.
“It’s great to release these guys at long last,” the Enterprise quoted
