Between March 30, 2012 and November 6, 2018, the California Department of Food and Agriculture (CDFA) confirmed the presence of the causative bacteria of the citrus disease huanglongbing (HLB) in citrus tree tissue and insect vectors collected in the cities of Cerritos, Duarte, Hacienda Heights, Lakewood, La Puente, Norwalk, Pico Rivera, Rosemead, San Gabriel, and Whittier of Los Angeles County. HLB is a devastating disease of citrus and is spread through feeding action be populations of the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. In order to determine the extent of the infestation, and to define an appropriate response area, additional surveys took please for several days over a one quarter-square mile area, centered on the detection sites. Based on the results of the surveys, implementation of the CDFA’s current ACP and HLB response strategies, which include treatment for ACP, are necessary for eradication and control.
