The Egyptian alfalfa weevil—Hypera brunneipennis (Boh.)—is causing economic losses in localized areas in Imperial and San Diego counties. Because it is damaging to crops in hot dry areas as well as in relatively cool, coastal localities, this pest poses a threat to all the alfalfa-and clover-producing districts in the state.
