To give growers and pest control advisors in the San Joaquin Valley an opportunity to scout for live Asian citrus psyllids, the Citrus Pest & Disease Prevention Program has organized a field trip taking growers and PCAs from the valley to Riverside County. This free, all-day event takes place Thursday, September 11th and includes guided inspection of infested citrus trees, a working lunch to discuss treatment recommendations and a tour of the Tamarixia rearing facility. The event is free – including transportation and lunch – and 3.5 hours of DPR continuing education credits are available. Register now: http://citrusinsider.org/event-registration/?ee=22
The California citrus industry is facing its biggest threat yet – the Asian citrus psyllid and the disease it can carry, Huanglongbing, also known as HLB or citrus greening disease. Citrus Insider is your hub for industry-specific information. We encourage you to survey and treat for the pest, be on the lookout for the disease and stay informed.

The following is from a press release issued by the San Luis Obispo County Agricultural Commissioner’s Office Monday, Aug. 11, 2014.
San Luis Obispo, CA — High density insect trapping and visual surveys conducted in response to the detection of an adult Asian Citrus Psyllid in a residential neighborhood in San Luis Obispo has resulted in the discovery of additional Asian Citrus Psyllids. Multiple Psyllid life stages were found at three additional properties located approximately one quarter to one third mile from the original site in the north eastern part of the city of San Luis Obispo.

The following press release was issued by the San Luis Obispo County Agricultural Commissioner’s office on Aug. 5, 2014. Additional details regarding potential regulatory implications for industry members will come soon.
San Luis Obispo, CA — The detection of an adult Asian Citrus Psyllid (ACP) in an insect trap in a residential neighborhood in northeast San Luis Obispo has prompted a high density trapping delimitation survey of the surrounding area. A quarantine restricting the movement of citrus nursery stock and citrus fruit will be established by the California Department of Food and Agriculture to prevent the spread of this serious plant pest. Control efforts will take place in the near future in the area immediately surrounding the detection.
This is the second detection of ACP in San Luis Obispo County. The first detection occurred this past March in Arroyo Grande; only a single ACP was detected. Intensive trapping and visual surveys are ongoing, but no additional insects have been detected. However, a quarantine restricting the movement of citrus nursery stock and citrus fruit remains in effect in a five-mile radius surrounding the Arroyo Grande detection site.
The Citrus Pest & Disease Prevention Program and U.S. Customs and Border Protection recently collaborated on a press conference to raise awareness of the dangers of bringing citrus fruit and plant material into the country from other areas. The backdrop for the event was the San Francisco International Airport, a hub of global travel in a multi-cultural city where many residents enjoy fresh, homegrown citrus fruit.
Developed by the top minds at University of California, California Citrus Mutual and Citrus Research Board, along with other industry leaders, a new area-wide treatment strategy is being introduced to citrus growers to organize the industry and allow for rapid communication if area-wide insecticide treatments are needed.
Coordinated treatments are the most effective way to manage the Asian citrus psyllid and thereby protect our state’s citrus from the incurable Huanglongbing disease, and this new strategy lays the framework for how neighboring growers should synchronize treatments to have the maximum impact on this pest. Right now, Tulare County is still in eradication mode, but the industry should plan for what may come next.
It has been a busy month for the San Diego County Asian Citrus Psyllid Task Force. We held three meetings to get growers thinking about their fall systemic coordinated treatments, and there were additional finds in the Rancho Santa Fe area – an area that has not had any finds in quite a while.
The meetings were held in Valley Center, Fallbrook and Pauma Valley and were well attended. As a new liaison in the area, the meetings not only helped open up the line of communication between me and the local industry, but they also served as a tool to keep growers informed about the Asian citrus psyllid and how to detect and manage a find. In fact, a grower recently contacted me to say that he could now find the psyllid after attending the meeting.
There are still many growers and homeowners with citrus who are unaware of ACP and HLB. I am now being contacted by people who are just learning about this problem and I will be visiting properties throughout July to make contact with the owners and bring them up to date. This includes properties with abandoned trees, new growers and homeowners with 10-25 trees.
Fresno and Madera Counties
There have not been any trap detections of Asian citrus psyllid in either Fresno or Madera Counties since October of 2013.
There has been one find in Kern County at a packing facility in Delano. CDFA has determined that this is a regulatory incident and no treatments are required. Trapping in the area has been increased and all citrus in the immediate area was visually examined for the presence of ACP.
There have three ACP finds in Tulare County, two in the Ivanhoe area and one found south of Farmersville. All commercial groves are in the process of being treated. Backyard trees will be treated by CDFA. Quarantines have been expanded as necessary. Continue reading
As the result of additional psyllid finds in Tulare County, the quarantine has been expanded by 14 square miles. The California Department of Food and Agriculture posted the following press release Thursday, June 19, 2014.
ASIAN CITRUS PSYLLID QUARANTINE EXPANSION IN TULARE COUNTY
SACRAMENTO, June 19, 2014 – An additional portion of Tulare County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of one psyllid west of Exeter near the community of Farmersville in Tulare County. This brings the total quarantine area in Tulare County to 870 square miles. Continue reading
Raising awareness of the citrus industry’s efforts to combat the Asian citrus psyllid and Huanglongbing in both residential and commercial areas is the first step in earning public support for the program. The Citrus Pest & Disease Prevention Program has been working on the growers’ behalf to earn positive media placements in leading news sources. Here are highlights of recent coverage.

The Citrus Pest & Disease Prevention Program introduces Enrico Ferro as the new grower liaison for San Diego County. Ferro graduated from the University of California, Riverside with a Bachelor of Science in Biology. He has worked as an independent pest control advisor (PCA) in the citrus and avocado industry since 1997. He started checking traps, releasing insects and scouting for his father Enrique in 1986. Ferro also has a QAL license and has used biological control to maintain low population levels of several citrus and avocado pests. Ferro also has an organic avocado grove in San Diego County that is planted to high density. He works with small and large growers (both conventional and organic operations) in Riverside and San Diego Counties. Ferro is also director of pest eradication and exclusion for the San Diego Farm Bureau and has been an active participant in the San Diego County Asian Citrus Psyllid Task Force meetings for the past two years.
Chairman of the Citrus Pest & Disease Prevention Program Nick Hill was recently interviewed by Sabrina Hill with Ag Net West Radio about the importance of halting the spread of the Asian citrus psyllid in the San Joaquin Valley. An important component of the fight against the psyllid is to have harvesters and other citrus industry crews abide by best management practices.

In May, being the Ventura County Asian citrus psyllid Grower Liaison kept me on my toes for what seemed like the entire month!
In addition to a confirmation in Moorpark that involved 15 properties, there was also a commercial property detection in Camarillo. These two new cases were juggled with the continuing tricky situation at a Fillmore packing house. Continue reading
