J. Quayle to the U.C. Plant Disease Laboratory at Whittier. In 1916 he correctly attributed resistance of black scale and California red scale to fumigation with HCN— one of the first reports of resistance. Quayle moved to Riverside in 1917, and the Division of Entomology of the Citrus Experiment Station was formed in 1918. Professor Quayle's studies on citrus insects and mites and their control brought worldwide recognition.
