Insect pests Control United States Periodicals. - 1346 - THREE-CORNERED ALFALTA HOPPER (Spissistilus festinus) - OKLAHOMA - Light, scattered populations present in Greer and Jackson County alfalfa. (Okla. Coop. Sur.). LEAFHOPPERS - OKLAHOMA - Some controls undertakin in Ames area, Major County. (Okla. Coop. Sur.). TEXAS - Several undetermined species damaging spelt wheat and oats in Guadalupe County. (Tex. Coop. Rpt.; Massey). ALFALFA WEEVIL (Hypera postica) - OHIO - Heaviest infestations found south of Highway 250 in Harrison County, east central area. Many acres of first and second-cutting alfalfa damaged. Several hundred acres treated in autumn. (Hill). MARYLAND - Larvae ranged 0-12 per 5 sweeps with a few adults in 4 alfalfa fields checked in Frederick County. (U. Md., Ent. Dept., Nov. 2, 10). MEXICAN BEAN BEETLE (Epilachna varivestis) - NORTH CAROLINA - Adults noted in Chowan County; fairly numerous in field of rye used as cover crop. Feeding on upper portions of blades. Det. by D. Ac Mount. (Overman). SOUTHWESTERN CORN BORER (Zeadiatraea grandiosella) - ALABAMA - Surveys completed in 14 northwest counties; infestations found in Jefferson, Walker, Fayette, Lamar, Marion, Franklin, Colbert, Lauderdale, Lawrence and Winston Counties. It is apparent that over-lapping infestations of Z. grandiosella and Diatraea crambidoides (southern cornstalk borer) exist in some of these counties as numerous specimens taken in corn where no internal girdling occurred. Suspicious specimens of Z. grandiosella collected in corn in Limestone, Morgan and Cullman Counties; these forwarded for confirmation. No suspects found in Blount County. St. Clair, Shelby and Clarke Counties, on fringe of infested area, yet to be surveyed. Total of 16 counties now known to be infested. Infestations much more noticeable in late corn than in earlier plantings. (McQueen) ALFALFA CATERPILLAR (Colias eurytheme) - NEW MEXICO - Ranged 3-10 larvae per 100 sweeps
