Insect pests Control United States Periodicals. - 966 - FALL ARMYWORM (Laphygma frugiperda) - NEW YORK - Larvae present on scattered groups of small corn plants in Hudson Valley. (N. Y. Wkly.

MARYLAND - Infesting over 50 percent of plants in large field of silage corn in Talbot County; moderate in late planted corn in Frederick County. (U. Md., Ent. Dept.). VIRGINIA - Considerable activity in Northampton County. (Hofmaster). Few present on soybeans in Charles City and New Kent Counties. (Settle, Aug. 16). ALABAMA - Continued outbreaks observed on soy- beans in Mobile and Baldwin Counties. (Buttrara). EUROPEAN CORN BORER (Ostrinia nubilalis) - WISCONSIN - Egg laying well underway, although egg masses still difficult to find. Examination of field of corn near Prairie du Chien revealed a third-stage larva, probably second generation. Dissection in this field showed 4 percent third instar, 32 percent fifth instar and 64 percent empty pupal cases. Dry conditions in several fields caused leaf rolling which tends to dislodge eggs. Some bird feeding observed on corn in Crawford County. (Wis. Ins. Sur.). MARYLAND - Second-generation larvae averaged 32 per 100 plants in 5 fields of wild corn checked in Talbot County. (U. Md., Ent. Dept.). DELAWARE - Adults increasing in blacklight traps in Sussex County. Comparatively fresh egg masses common on corn in area. (Huber, Burbutis). NEW YORK - Small borers entering whorls of corn and small percentage of silks in Hudson Valley. Inspection of 300 untreated sweet corn plants at Poughkeepsie, August 16, in mid to late-whorl stage, showed 17 percent of plants with recently hatched larvae. (N. Y. Wkly. Rpt., Aug. 20). LESSER CORNSTALK BORER (Elasmopalpus lignosellus) - NORTH CAROLINA - Destroyed one-half to two-thirds of a 4-acre stand of grain sorghum in Cleveland County. (Robertson)
