On August 25, Lindcove Research Center hosted the first field event of year 2021! A field day was dedicated to discussing information on citrus thrips biology, damage, and management options available. Event kicked off by asking questions to the 42 participants about their pest management needs. Dr. Sandipa Gautam talked about citrus thrips biology and fruit scarring damage on different citrus varieties. Data on citrus thrips resistance to Delegate showed that resistance in San Joaquin Valley populations of citrus thrips is increasing and this is confirmed by PCA and grower observations. This year seemed to be a problem year for citrus thrips, with growers spraying up to five times to control thrips. Dr. Beth Grafton-Cardwell discussed citrus thrips trials screening different chemicals and emphasized the importance of using different class of pesticides for resistant management in citrus thrips. Participants observed thrips and the scarring damage caused by citrus thrips.

University of California Cooperative Extension (UCCE) in Tulare County and the Lindcove Research and Extension Center (LREC) co-hosted three College of the Sequoias (COS) interns enrolled in the SURGE (Student Undergraduate Research Group Experience) program. Student research programs are completed under the academic mentorship of UCCE Advisors, while LREC provides the land and laboratory infrastructure to achieve research goals. Elizabeth Fichtner, UCCE Farm Advisor covering nuts, olives, and prunes, initiated the partnership with COS in 2014, and was joined in 2015 by Allison Ferry-Abee, UCCE Farm Advisor covering viticulture.
Yelena Martinez, a COS Chemistry major, was the first SURGE intern hosted by UCCE and LREC. Yelena's 2014 project focused on plant physiology and the potential for plant growth regulator treatments to mitigate alternate bearing in olive. Since completion of her internship, Yelena has worked as a Student Assistant in Fichtner's research program and has additionally worked for LREC on the annual citrus tristeza survey. Yelena plans to transfer to a 4 year university in 2016 to complete her BS in chemistry.
Stephanie Doria and Edra Lona, 2015 SURGE interns, are conducting research in the new plant pathology laboratory at LREC. Both students' projects address replant issues associated with pistachio bushy top syndrome, a newly recognized disease caused by a plant pathogenic bacterium. Stephanie was a Biology major at COS and is transferring to UC Davis to complete her BS in Evolution, Ecology, and Biodiversity. Edra was a RN/Biology major at COS and is transferring to Fresno State to complete her BS in Microbiology. Since completing their SURGE projects, both students have joined Fichtner's research program as Student Assistants and will continue working at LREC until the commencement of the fall semester.
