Abstract

The sorghum midge—Contarinia sor-ghicola (Coquillet)—the most important pest of grain sorghums in the Southern states—was found in Tulare county on October 6, 1960. This apparently is the first record of this midge west of New Mexico. Surveys at the time of the initial discovery indicate that it is firmly established in Tulare County and is also present in Madera, Fresno, Kings, and Kern counties.
