Detection of Citrus Disease Huanglongbing Triggers Quarantine Expansion in Portions of San Bernardino and Los Angeles Counties
SACRAMENTO – November 22, 2019 – A quarantine has been declared following the detection of the citrus disease Huanglongbing (HLB), or citrus greening, in a single citrus tree in an unincorporated area of San Bernardino County, near Montclair. This is the first time the plant disease has been detected in San Bernardino County. CDFA is working with the United States Department of Agriculture (USDA) and the San Bernardino County and Los Angeles County agricultural commissioners on this project.
The 93-square mile quarantine area will link up with existing quarantines in Los Angeles and Orange Counties, creating a contiguous 1,015-square-mile area. The new portion is bordered on the north by I-210; on the south by Chino Airport; on the west by Highway 57; and on the east by Ontario International Airport. HLB quarantine maps for San Bernardino and Los Angeles counties are available online at: https://www.cdfa.ca.gov/plant/hlb/regulation.html. Please check this link for future quarantine expansions in these counties, should they occur. Quarantines are already in place for HLB in portions of Los Angeles, Orange and Riverside counties.

DATOC Welcomes New Members
An Update from the Data Analysis and Tactical Operations Center (DATOC): “The Data Analysis and Tactical Operations Center (DATOC) is pleased to announce that two new members have joined the expert panel: Dr. Kerry Mauck and Dr. Michelle Heck.
Dr. Mauck is an Assistant Professor of Entomology at UC Riverside, and her expertise is in insect behavior and chemical ecology. Dr. Mauck’s research group is pursuing projects on the diversity and evolution of 'Candidatus Liberibacter asiaticus' (CLas), the bacterium that causes huanglongbing.
Dr. Heck is a Research Molecular Biologist with the USDA ARS Emerging Pests and Pathogens Research Unit in Ithaca, New York. Dr. Heck has been pursuing projects to develop novel management strategies for Huanglongbing, and to identify factors that affect the efficacy of CLas transmission.

2019 CCNS Annual Meeting Recap
The 2019 Annual Meeting of the California Citrus Nursery Society (CCNS) brought together researchers, nurserymen and other citrus industry professionals to discuss critical topics of interest to the citrus nursery industry, with an emphasis on ACP/HLB. Several researchers were invited to discuss their research at the General Meeting which included updates on the breeding of new HLB tolerant/resistant rootstocks (Mikeal Roose, Ph.D.), certification of HLB-free plant material (Georgios Vidalakis, Ph.D.), citrus growing photoperiods (Gurreet Brar, Ph.D.), citrus under protection structures (CUPS) (Philippe Rolshausen, Ph.D.), ACP/HLB interactions (Beth Grafton-Cardwell, Ph.D.) and imidacloprid treatments in containerized citrus (Frank Byrne, Ph.D.). Additional presentations were made by CDFA staff to discuss the current status of HLB management in California (Magally Luque-Williams) and important updates regarding ACP/HLB quarantine areas and approved structures for citrus nursery stock (Nawal Sharma).

Citrus Field Sites Needed to Determine Better
Strategies for Managing Roof Rats in Citrus Orchards
Having problems with roof rats in your citrus orchards? The University of California (UC) Cooperative Extension and UC Davis are engaging in a two-year study designed to develop an effective management program for removing roof rats from these orchards, but we need your help. Starting in January 2020, we will need 5 orchards to begin testing approaches for monitoring roof rat activity in orchards. We will also determine movement patterns of roof rats in orchards to determine where rats are spending their time and how far they move daily. This information will provide the framework to then test the efficacy of various management tools for removing roof rats from orchards, which will hopefully start in January 2021.
If you are potentially interested in participating in this study, please contact
Roger Baldwin for additional details (email@example.com; 530-752-4551).
