HORNFLIES (Haematobia irritans) are an economic problem in pasture cattle production in the central San Joaquin Valley during the summer and fall months. Although thousands of flies may be present on individual range cattle, each taking a blood meal several times daily, it is difficult to evaluate the exact economic loss. Infested cattle spend a great deal of time and energy ineffectually warding off hornflies, with resulting stress and weight loss.
