Asian citrus psyllids in the city of Santa Barbara.
I had a visit from Santa Barbara County Agriculture Control this afternoon and was told an Asian citrus
psyllid was found in a trap north of Cliff Drive on the west mesa. I now have a trrap in my orange tree.
Checked their website and found no other info, but it may have been found today.
The psyllid is an efficient carrier of the bacterium that causes the disease called Huanglongbing (HLB) or
citrus greening because the fruit does not color properly. Symptoms of HLB include yellow shoots and
mottling and yellowing of leaves due to lack of the green pigment chlorophyll.
Infected trees are stunted, sparsely foliated, and may bloom off-season. In addition, there is twig
dieback, leaf and fruit drop, production of small, lopsided, hard fruit, and small, dark aborted seeds.
There is no cure for HLB, and diseased trees must be removed as quickly as possible to prevent spread
of the disease.
