“There’s always the risk that a few will escape.”
Although a few psyllids have shown up in the commercial growing regions in northern regions, they have been knocked out with pesticides as soon as they were discovered and have not become established there.
Until that happens, efforts will continue to contain the psyllid in southern regions — a challenge because of plant smuggling and the suspicion that backyard psyllid-infested plants are given as gifts or spread to other areas as residents move.
“They represent a high dispersal threat into commercial production areas,” Hoddle said.
Hoddle is pleased with the proactive efforts being made in California to control both the psyllids and the disease.
“They’re keeping a close eye on the spread, and when they make detections, they swoop into action and deal with it quickly,” he said
