Hannah Kahl and Tobias Mueller, research staff for Dr. Bodil Cass and Dr. Jay Rosenheim in the Entomology Department of UC Davis are conducting experiments in the laboratory and orchards at Lindcove Research and Extension Center.  The goal of the research is to determine if earwigs, katydids and citrus thrips cause significant damage to each of the commonly marketed groups of mandarins.  If certain varieties are not susceptible to damage, this could greatly reduce pesticide treatments in those varieties.  This work is being funded by the Citrus Research Board and the California Department of Pesticide Regulation.
