resentations on citrus thrips, katydid and earwig citrus fruit scarring were made by Jay Rosenheim, Bodil Cass and Hanna Kahl on Aug 21 at a Lindcove Research and Extension Center field day. Exciting new data from their research conducted at LREC shows that thrips, earwigs and katydids dislike feeding on citrus fruit in the Tango group (Citrus reticulata) and this confirms PCA and grower observations that this mandarin variety does not require insecticide treatments for these pests. Other mandarin varieties show varying levels of susceptibility. Beth Grafton-Cardwell and Stephanie Doria discussed their current citrus thrips insecticide trial and best practices for managing thrips.

Each year, Agricultural Technician staff (Donald Cleek, Gerry Perez and Jose Trujillo) from the Lindcove Research and Extension Center travel to UC Riverside to assist the citrus breeding program of DR. Mikeal Roose and Dr. Tracy Kahn by grafting citrus seedlings for various experiments. LREC staff assisted Toni Sievert, Zach Thomas and Carene Trunnelle with budding 965 trees in two days! This is a wonderful example of LREC support of their scientists.

Dr. Beth Grafton-Cardwell's entomology staff researchers Stephanie Doria, Joel Leonard, and Matt Morris as well as Lindcove staff researcher Sal Barcenas have been on the hunt for Fuller rose beetle eggs in an experiment at Lindcove. Treatments of Sevin, Actara, Exirel and Minecto Pro were applied to skirt-pruned trees in August and October. Now is harvest time, and the LREC agricultural crews are picking all fruit from each treatment tree into separate bins (700-1000 fruit per tree) and the research staff is painstakingly removing the calyx from each fruit and examining that region for Fuller rose beetle eggs. From this study we will determine the level of efficacy of these foliar treatments. While Fuller rose beetle is not considered a damaging pest in California citrus, treatments are required by S. Korea to minimize the risk of transporting Fuller rose beetle to S. Korean where it is not currently found.

Glenn Wright (U. Arizona) is collaborating with Mikeal Roose and Tracy Kahn (UC Riverside) to evaluate a rootstock trial for Limoneira 8A Lisbon lemon at the Lindcove Research and Extension Center. This trial is one of three lemon trials located in the San Joaquin Valley, Ventura County area, and the Coachella Valley. Trees of Limoneira 8A Lisbon lemon, a popular selection in California, are being grown on 11 rootstocks. Glenn is utilizing the LREC fruit grading system to evaluate the size, color, grade, weight and number of fruit per tree. This trial will be highlighted at the Fruit Display event on Dec 14.
