Mexican Fruit Fly Quarantine in Portion of Los Angeles County

Three Flies Detected in Long Beach

CDFA News Release

A portion of Los Angeles County, including the Los Angeles and Long Beach ports, has been placed under quarantine for the Mexican fruit fly following the detection of three flies, including two mated females, within the City of Long Beach. Mated females are significant because they indicate a breeding population that increases the risk of spread of this pest. CDFA is working collaboratively on this project with the United States Department of Agriculture (USDA) and the Los Angeles County Agricultural Commissioner’s Office.

The quarantine area measures 79 square miles, bordered on the north by CA-91; on the south by the Pacific Ocean; on the west by I-110; and on the east by Palo Verde Avenue. A link to the quarantine map may be found here: www.cdfa.ca.gov/plant/mexfly/regulation.html.

Sterile male Mexican fruit flies will be released in the area as part of the eradication effort. The release rate will be approximately 325,000 sterile males per square mile per week in an area up to 50 square miles around the infestation. Sterile male flies mate with fertile female flies in the natural environment but produce no offspring. The Mexican fruit fly population decreases as the wild flies reach the end of their natural life span with no offspring to replace them, ultimately resulting in the eradication of the pest. In addition, properties within 200 meters of detection sites are being treated with an organic formulation of Spinosad, which originates from naturally-occurring bacteria, in order to remove any mated female fruit flies and reduce the density of the population. Finally, fruit removal will occur within 100 meters of properties with larval detections and/or mated female detections.

The quarantine affects any growers, wholesalers, and retailers of susceptible fruit in the area as well as nurseries that grow and sell Mexican fruit fly host plants. Those businesses are all required to take steps to protect against the spread of the pest. At the Long Beach/Los Angeles ports, exports as well as imports may be impacted depending on specific circumstances. The quarantine will also affect local residents growing host commodities on their property. Movement of those commodities is not permitted. Residents are urged to consume homegrown produce on site. These actions protect against the spread of the infestation to nearby regions, where it could affect California’s food supply as well as backyard gardens and landscapes.

The Mexican fruit fly can infest more than 50 types of fruits and vegetables. For more information on this pest, please see a pest profile at: www.cdfa.ca.gov/plant/go/MexFly. Residents who believe their fruits and vegetables may be infested with fruit fly larvae are encouraged to call the state’s toll-free Pest Hotline at 1-800-491-1899.

While fruit flies and other invasive species that threaten California’s crops and natural environment are sometimes detected in agricultural areas, the vast majority are found in urban and suburban communities. The most common pathway for these invasive species to enter our state is by “hitchhiking” in fruits and vegetables brought back illegally by travelers as they return from infested regions of the world. To help protect California’s agriculture and natural resources, CDFA urges travelers to follow the Don’t Pack a Pest program guidelines (www.dontpackapest.com).

Calif. Profs Win Irrigation E3 Leader Awards

Irrigation E3 Leader Awards Go to Two California Faculty

The Irrigation Foundation has named 15 outstanding students and faculty as winners of the 2015 Irrigation E3 Program. The Foundation selected two faculty 2015 Irrigation E3 Leaders, both in California, Florence Cassel, Fresno State and Tim Ellsworth, West Hills College Coalinga.

This year’s class of faculty and students will receive an all-expenses-paid trip next week to the Irrigation Show & Education Conference, Nov. 9 – 13, in Long Beach, Calif.

Founded in 2012, the E3 program provides students and faculty with exposure, experience and education in the irrigation industry. Academics nominate outstanding students for consideration as E3 Learners and/or apply to become E3 Leaders themselves.

To qualify to apply for Irrigation E3 Leader status, an instructor must be teaching, or will be teaching within the next six months, irrigation-related coursework at a North American community college, university or similar institution of higher learning. Prior winners may not reapply.

Chosen faculty will have the opportunity to participate in education classes, industry sessions and networking events. Working with academics is essential to the Foundation’s mission of attracting people to careers in irrigation by supplying the irrigation industry with educated professionals. Faculty members help shape the future career paths of their students and keeping instructors up-to-date on the latest and greatest in the irrigation industry is a must.

“This is the fourth year of the program, and the Foundation is sending a record number of students to the show,” said senior foundation manager Janine Sparrowgrove. “We are excited to give the students and faculty the opportunity to attend classes and gain exposure to industry companies and technologies.”

Florence Cassel Sharma, Assistant Professor Irrigation/Water Management, Jordan College of Agricultural Sciences and Technology, Department of Plant Science, California State University, Fresno researches optimizing water use efficiency through low and deficit irrigation practices, improving irrigation scheduling, and utilizing remote sensing techniques for water resources management, crop water use, and soil salinity assessment. Assistant director of research of the Center for Irrigation Technology, Sharma is a recipient of the 2009 Outstanding Research and Scholarly Activity Award for the Jordan College of Agricultural Sciences and Technology.

Tim Ellsworth, agriculture technology instructor at West Hills College Coalinga, researches primarily soil science with a focus on precision agriculture and nutrient management. He currently serves on the advisory board for the Canadian Biochar Consortium.

Prior to West Hills, Ellsworth was a professor and faculty director of the online master’s program for the Department of Natural Resources and Environmental Science at University of Illinois, Urbana-Champaign, a soil scientist with the USDA U.S. Salinity Laboratory, a visiting faculty member at the Centre for Water Research, Department of Civil Engineering, University of Western Australia in Perth and a senior scientist performing hazard assessments and hazard evaluations for the U.S. Army with regard to management of the U.S. Army Chemical Weapon Stockpile.
