- 543 - 



Infestations ranged 1-5 percent in Richmond and Westmoreland Counties. (Allen). 

 NORTH CAROLINA - Infested 2 percent of corn with ears in Franklin, Wilson, Bertie, 

 Hertford, and Northampton Counties. Second-generation larvae beginning to 

 penetrate stalks. (Hunt). KENTUCKY - Larvae light and scattered in Graves, 

 Hickman, and Carlisle Counties. (Barnett) . WEST VIRGINIA - Generally light state- 

 wide; damage 20 percent in one Monroe County field. (W. Va . Ins. Sur.). 



OHIO - 0. nubilalis damage evident on 75+ percent of no-till corn in Harrison 

 County July 15. (Holdsworth) . MICHIGAN - Warm weather advanced normal emergence 

 date for second brood. Total of 26 adults collected at Monroe County blacklight 

 station. Limited egg laying in progress, will peak next 10-14 days. Larval 

 problems expected to continue until frost. Second brood about 7 days earlier than 

 1970, 14 days ahead of 1969 season. (Newman). WISCONSIN - No emergence of second- 

 flight moths in blacklight trap catches from Lancaster to Plover. In eastern 

 counties, moth catches continue relatively heavy at few locations. Larval 

 development variable. (Wis. Ins. Sur.). ILLINOIS - Development retarded due to 

 cooler weather. First-generation borers per 100 stalks averaged by area: North- 

 west 7, northeast 2, west 16, central 4, west-southwest 6, and southwest 19. 

 In southern and northwestern areas, pupation should be complete and moth emergence 

 advanced. Egg laying progressing rapidly, should peak next 10 days; little hatch 

 noted. Egg laying should be rapid in west-southwest and western areas. Little egg 

 laying will take place in northern area for about 10 days. (Sur. Bui.). MINNESOTA - 

 Pupation started; most borers in late instars. If present weather prevails, bulk 

 of moth flight and egg laying should start first week of August. Some early moths 

 seen past week. Populations in west-central district lightest north of Swift 

 County; no change expected. Same true for northwest district where populations 

 continue light. Heaviest counts and damage in State south of line from Minneapolis 

 and St. Paul west to State line. Stalk breakage above and below ear due to 

 tunneling becoming noticeable in many fields. Tassels breaking off but pollination 

 not affected in fields surveyed. (Minn. Ins. Rpt . ) . 



SOUTH DAKOTA - First-brood 0. nubilalis larvae continue to damage untreated corn 

 in eastern area. Pupae foun3^ July 15 near Freeman in eastern Hutchinson County. 

 Early larvae still present in Brookings County June 19. (Jones, Kantack) . 

 NEBRASKA - First emergence of second-brood moths noted at Lincoln, Lancaster 

 County, July 20 and in Hall County July 22. One Lancaster County cornfield near 

 100 percent infested with 1-3 third to fifth instars and occasional pupa. 

 Pupation estimated at about 35 percent, emergence less than 1 percent (Keith, 

 et al.). In 6 Dawson County fields, plants averaged about 30 percent infested 

 with first-brood borers. (Keith) . Corn plants ranged 30-70 percent infested in 7 

 Hall County fields. (Roselle) . KANSAS - Recent blacklight trap catches indicate 

 first-generation moths beginning to emerge in Republic County. Most pupated in 

 corn in Republic County and emerged in Brown County. Freshly laid eggs found in 

 field of pretassel, late-planted corn in Brown County and none found in Republic 

 County. In field in Brown County where 80 percent of plants infested with 1-3 

 second and third instars, 14 days ago, less than 10 percent of stalks bored this 

 week, indicating high larval mortality due to unknown causes. First-generation 

 borer damage appears to be much lower than 1970 in Brown County. (Bell). MISSOURI - 

 Counts in late corn in southeast area showed 0-22 egg masses per 100 plants, small 

 larvae on 5-71 percent of plants. (Munson) . ARKANSAS - Limited survey indicates no 

 problem in northeast area where corn acreage higher than in other areas. Most of 

 crop planted early. (Boyer) . 



WESTERN BEAN CUTWORM ( Loxagrotis albicosta ) - COLORADO - Adults appearing in light 

 traps in Weld County; range 0-6 per week. (Urano) . NEBRASKA - Moth flights heavy 

 in Parks area, Dundy County; about 2,500 moths caught each night in blacklight 

 trap operated July 17-18. Egg masses averaged less than 1 per 100 plants in 3 

 irrigated cornfields in Hitchcock County; averaged 1 per 50 plants in 2 

 irrigated and 2 dryland fields in Dundy County. (Munson, Wedberg) .
