Technical Abstract: Cotton aphid and western tarnished plant bug (WTPB) are the two most damaging pests in California cotton. Neozygites fresenii, a fungus common in Arkansas was released for biological control of aphids. Unfortunately, aphid populations in the release field were very low and the fungus did not establish. In addition, Beauveria bassiana was found infecting up to 65% of WTPB in alfalfa fields in the San Joaquin Valley (SJV). B. bassinana is a common entomopathogenic fungus but has not been previously reported from California populations of WTPB. This fungus is now being cultured and examined for potential use as a biological control agent.
