"Basically, you just look really closely (at new growth) with any kind of magnifying device you have to see if you can find any insects on there," Grafton-Cardwell said.
If tiny yellow eggs, sesame seed-sized nymphs, or ACP adults are found, take action. Maps, treatment protocols and other information that detail what to do when ACP is present are available at http://ucanr.edu/acp.
Since ACP can spread the devastating citrus disease huanglongbing (HLB), controlling the insect population will buy time for researchers working around the world to find a way to grow healthy and delicious citrus fruit in the presence of HLB.
Yurong reported that the disease has been found in a dozen Southern California trees. Grafton-Cardwell figures Valley trees will ultimately get infected.
“It's really important to detect Asian citrus psyllid in backyard trees because one psyllid can carry the disease from tree to tree in a residential landscape,” Windbiel-Rojas. “Citrus growers, they treat all their fields, but home gardeners don't necessarily treat or monitor their backyard trees so it can spread a lot faster in backyards than in managed citrus orchards.”
