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.
