An arborist reported an unusual pest found on an olive tree in Riverside CA late 2016. CDFA identified it as an Olive Bark Beetle (OBB) Phloeotribus scarabaeoides (http://blogs.cdfa.ca.gov/Section3162/?tag=olive-bark-beetle)
Currently, the pest status is Q (quarantined) but it is recommended to be changed to B.
The report states the OBB has been found at olive trees at grape vineyard as well as a residence and 3 nurseries, all in Riverside County. Surveys of olive trees at nurseries in other counties have not found any OBB.
The beetle is very small (2mm) and brownish-gray so it is difficult to detect. See https://www.forestryimages.org/browse/subthumb.cfm?sub=4146 for photos.
Current hosts are olive, Fraxinus spp., privet (Ligustrum sp.), lilac (Syringa), Phyllirea sp.
Damage is caused by larval feeding and then by adults on weakened stems and branches of causing decline and sometimes death
Damage can also be caused by adults creating feeding incisions on small, healthy branches causing the tips to dry out and die, or by adults damaging axillary buds when trying to initiate small galleries or holes where they can hibernate.
Good information about its biology and life cycle can be found on http://www7.inra.fr/hyppz/RAVAGEUR/6phlsca.htm

FROM UC Pesticide SAFETY AND EDUCATION GROUP:
We are in the midst of a new and changing era of Worker Protection Standards (WPS). The U.S. Environmental Protection Agency (EPA) and the California Department of Pesticide Regulation (DPR) recently published the revised WPS, which is meant to increase protections for agricultural fieldworkers and pesticide handlers from pesticide exposure when they're working in farms, forests, nurseries and greenhouses. The changes are already affecting California agriculture!
What major regulatory changes have already gone into effect?
Several changes are required to have been in place as of January 2, 2017. These include:
* All 417,000 fieldworkers in California must attend annual pesticide safety training.
* Records of all fieldworker pesticide safety trainings must be kept on file for 2 years.
* Fields must be posted when the restricted entry interval (REI) exceeds 48 hours.
* “Application-exclusion zones” must be implemented to prevent the entry of anyone into areas up to 100 feet from pesticide application equipment.
* Instructors previously qualified via a DPR-approved Instructor Training programs (Train the Trainer) are qualified to train through 2017. If you wish to be qualified to train fieldworkers and handlers after December 31, 2017 using this qualification, you must complete an updated, DPR-approved Train the Trainer workshop.
Now is the time to make sure these changes are put in place!
What major regulatory changes are still in store for us? When will they happen?
The regulatory changes that must be in place by January 2, 2018 include:
* Additional training topics for fieldworkers and handlers have to be added to the curriculum.
* Handlers have to suspend an application if anyone enters the application exclusion zone.
Who do these changes affect?
Many people who work in the California agricultural community will be impacted by the WPS revisions. These include fieldworkers, pesticide handlers, farm labor contractors, private and in-house safety trainers, growers, farm managers, licensed pesticide applicators (private and commercial), pest control advisors (PCAs), and crop consultants, to name a few.
How do I know if I am qualified to train?
If you attended one of the DPR-approved Train-the-Trainer programs you are qualified through 2017. However, if you wish to continue training after the end of the year, you must complete a DPR-approved Instructor Training Program, which includes the 2018 training topic requirements.
If you maintain certain licenses/government designations, including PAC, QAC, QAL, PCA, and certain County Biologist licenses you are qualified to train. UCCE Advisors are also qualified to train.
How can I get qualified as a trainer?
To become a trainer, take an Instructor Training program that is approved by DPR for 2018 topics. The University of California Pesticide Safety Education Program (part of the UC Statewide Integrated Pest Management Program, UC IPM), in partnership with AgSafe, will offer multiple workshops this spring that cover the new federal requirements for fieldworker and handler training. You can reserve your spot now. At the end of the training you will be a certified pesticide safety instructor.
If I am currently qualified, how can I make sure I stay up to date on all the new requirements?
If you are currently qualified as a trainer because you maintain a California PAC, QAC, or QAL, or if you are a PCA, you can attend an Instructor Training Program this spring to learn about the new WPS requirements and additional training topics. While a certification may qualify you, an Instructor Training Program will prepare you to train! Register today!

Hi, I'm longan fruit. I almost made it into the U.S. from Vietnam. Luckily the person that was carrying it knew that she couldn't carry fresh fruit from Vietnam into the U.S. Here's my story.
I was put into a carry-on bag before I left Vietnam. While my traveler tried to eat as much as she could before getting to LAX there was still some left by the time she arrived. She also had some dried fruits in her bag. She knew that she couldn't take the fresh fruit in but she was not sure about the dried fruits in so she wanted to ask Customs about that. My traveler dutifully marked the boxes on the paper customs form before she left the plane.
When she got off the plane she looked around to see if there was a security box that's often found in airports for travelers to throw out fresh fruits and vegetables that are not allowed in the U.S. However not seeing one, she continued on through the customs process. LAX also has an electronic kiosk a traveler can use to declare if there are any fruits or vegetables that the traveler is bringing in. My traveler again marked that she had some fruits. It would have been very easy for the kiosk to be programmed to provide additional instruction telling travelers that they should go to a secondary inspection line but there was nothing.
My traveler then continued through the lines, picked up her checked baggage (which did not have any plant material) and then followed the others to leave the airport. At the final check she asked the officer what she should do with the fresh fruit since she expected at some point there would be an opportunity to get rid of it and this seemed like the last chance. The officer said she needed to go to another inspection area. Which she did and gave me to the USDA officer. The officers there also x-rayed the rest of her baggage just to be sure that there was nothing else in her luggage. What shocked my traveler was that if she had not asked about the fruit, she could have just walked out of the airport possibly carrying an exotic pest.
In this case, I did not make it out of the airport. However what would happen if there is a traveler that is carrying fruit or other live plant material that is unaware that these may carry pests that could impact California's agriculture? Some backyard citrus trees were likely infected with HLB (the bacteria that causes citrus greening) through infected stems used for grafting that were probably carried from overseas travelers. If these travelers were not aware that they could not bring them in, it's likely that they too just walked out of the airport. I would say it's not their fault - it's just that there is a missing step.
It's hard to stop someone who is intentionally trying to bring small amounts of plant material into the U.S. in their carry-on bags. However, for the rest of the out of country travelers, there are a number of actions that could be implemented. Some suggestions are
1. Modify a paper declaration form to alert travelers that they need to go through the USDA inspection line once they arrive.
2. Provide a box that is sealed so that pests cannot escape letting travelers anonymously throw out plant material that they are carrying.
3. When using the electronic customs kiosk, there should be an alert telling the traveler that they need to go through USDA inspection if the traveler checks the box in the affirmative when asked about plant material.
I didn't make it but other fruits, vegetables, and plant material probably get through every day. While the suggestions listed above will not catch everything, at least we can reduce some of it.
