Southwestern corn borer infestations were much more serious in ARKANSAS in late corn than in early corn. For the first time, a survey was made in 95 fields in 19 coiinties, showing that an average of percent of corn lodged was a result of infestations of this pest. Infestations of southwestern corn borer were somewhat higher throughout OKLAHOMA during 1960 than those noted during the 1959 season, and the pest was generally not of economic importance in KANSAS.

Infestations of southwestern corn borer were somewhat higher throughout OKLAHOMA during 1960 than those noted during the 1959 season, and the pest was generally not of economic importance in KANSAS. Checks of several fields of corn in southwest MISSOURI showed an over- wintering survival of 7 percent for southwestern corn borer. A light, first- brood infestation occurred in June and early July. The 1960 survey in Missouri showed a higher percent of girdled stalks than for the past several years. Southwestern corn borer infested corn in TENNESSEE and was found in Shelby and Tipton Coiinties for the first time during Distribution of Southwestern Corn Borer Summer and winter larval forms of SOUTHERN CORNSTALK BORER (Diatraea crambidoides) infested many fields of corn in Sussex County, DELAWARE, during September; and infestations of this pest were moderate in field corn on the lower Eastern Shore of MARYLAND. CORN ROOT WEBWORM (Crambus caliginosellus) seriously injured young corn at localities in Kent, Queen Annes and Talbot Counties, Maryland. SUGARCANE BORER (Diatraea saccharalis) populations were extremely heavy in late grain sorghum in the Brazos River area of TEXAS, with somewhat less damage noted on corn and grain sorghum in the coastal area of that State and infestations of sugarcane borer in corn were light in LOUISIANA. Light infestations of LESSER CORNSTALK BORER (Elasmopalpus lignosellus) appeared in central and southwest ARIZONA on yoxing corn and sorghum during June, remaining light in most cases and with damage generally lighter than during previous years. Lesser cornstalk borer was not
