Following finds of several adults in yellow sticky cards in a residential area of Dinuba, young trees infested with all stages of psyllids were discovered nearby. The fact that all stages were found and the trees were young, suggests that the trees could have been infested when they were planted and the trees possibly came from outside the San Joaquin Valley or the infestation got started near these young trees a while ago (this is being investigated). This situation points out the need to educate everyone that they must never move...
In California, the news has been buzzing about Asian Citrus Psyllid after 6 more were found in Tulare County.
All of us have to work together in this effort. University of California, Agriculture and Natural Resources (UCANR) has put together a great website that highlights the distribution and management of Asian Citrus Psyllid. This includes a great map and interactive cost estimators for homeowners and
Californians are surrounded by plants that were developed by researchers. If you are from Santa Rosa, you are probably familiar with Luther Burbank. Burbank developed many varieties that we enjoy today including the plumcot, the shasta daisy and hundreds of other fruits, vegetables, and ornamentals.
In addition to Burbank, researchers and California homeowners have brought new plants to our backyards. Right now, one of those plants is being threatened by the Asian Citrus Psyllid and the disease, Huanglongbing. A tree that was the original parent to the navel oranges we enjoy is located at the heart of the psyllid outbreak - in Riverside. Everyone is trying to save it.

For the last few years citrus growers in the San Joaquin Valley have been nervously watching the establishment of Asian citrus psyllid in southern California and bracing themselves for the day of northward movement. That day arrived in November 2012 when two psyllids (Strathmore 16 Nov. and Terra Bella 21 Nov.) were caught on yellow sticky card traps, in addition to a third capture back in January 2012. These captures have now resulted in restrictions on the movement of citrus in the heart of California's principal citrus production region.
Asian citrus psyllid is a small...
