Abstract

The Egyptian alfalfa weevil—Hypera brunneipennis (Boh.)—has become an increasingly serious pest of alfalfa in southern California during recent years. In 1961 weevil populations were the heaviest on record, and in the Imperial Valley alone many thousands of acres of alfalfa required insecticidal treatment. All evidence indicates that the Egyptian alfalfa weevil will continue to pose a serious threat to first and second cutting alfalfa in southern California.
