Efforts to contain a tiny bug that can devastate the state's citrus industry are increasing since the recent trapping of another one of the insects in Tulare County. Now the state's quarantine measures 86 square miles in the heart of the San Joaquin Valley citrus belt. Additional smaller quarantines are in place in neighboring Fresno and Kern counties. The Asian citrus psyillid is capable of carrying a disease commonly called citrus greening.
