SUGARBEET ROOT IVLAGGOT (Tetanops myopaef ormis ) - NORTH DAKOTA - Egg hatch light 

 (most eggs nonviable, apparently drying up) and maggots feeding on new beets 

 in Pembina, Walsh, Grand Forks, and Traill Counties. Damage light (less than 1 

 percent) in these counties except for localized spots near Forest River where 

 up to 30 maggots per beet root found. In Cass County near Kindred, stunted and 

 wilted plants with 1-6 maggots per root found in single field; damage evident 

 in 1 percent of plants. In distribution survey in Grand Forks and Traill Coun- 

 ties, adults, eggs, or maggots present in all fields surveyed except 3 fields 

 in southern Traill County. (Kaatz, Brandvik) . MINNESOTA - Surveys in Wilkin 

 County, at least in northern half, showed adults trace. In Clay County, no new 

 areas infested. Adults and eggs noted in light soil areas and no egg hatch. 

 No adults noted in heavy soils of Norman and western Polk Counties. (Minn. Pest 

 Rpt.). 



SPINACH LEAFMINER (Pegomyia hyoscyami ) - WYOMING - Damage about ended in Goshen,

MISCELLANEOUS FIELD CROPS 



REDBACKED CUTWORM (Euxoa ochrogaster ) - OREGON - Larvae destroyed 345 acres of 

 500-acre mint planting near Culver, Jefferson County, Damage first noted in late 

 May. Many plants cut off twice. Damage to infested acreage enhanced by severe 

 windstorm. Current survey revealed extensive areas, especially those of higher 

 relief within field, still barren. Mint appears to be recovering over most of 

 field. Population mostly pupae with adults just appearing. Controls applied 3 

 times. Sprays proved ineffective but bait applications effective. (Westcott, 

 Wheeler) . 



POTATOES, TOMATOES, PEPPERS 



COLORADO POTATO BEETLE (Leptinotarsa decemlineata ) - UTAH - Still major problem 

 on potatoes in northern areas . (Knowlton, Olson) . COLORADO - Appearing in Weld 

 County. Larvae up to 20 per plant in one field. (Hantsbarger) . 



TUBER FLEA BEETLE (Epitrix tuberis ) - OREGON - Previous predictions of population 

 buildup in western areas appear to be substantiated on basis of number of reports 

 of damage received. Additional infestations reported; commercial potato planting 

 in Multnomah County, and backyard garden tomato plantings in Philomath area, 

 Benton County. (Crowell, Westcott) . 



APHIDS - MAINE - Numbers on 1,200 plants in Aroostook County: Aphis nasturtii 

 (buckthorn aphid) 218, Myzus persicae (green peach aphid) 9, Macros iphum 

 euphorbiae (potato aphi"?) ?39, Acyrthosiphon solani (foxglove aphid) 4. (Kimball) . 

 NEW JERSEY - Myzus persicae building up on eggplant, pepper, potato, and tomato 

 throughout State. Continuation of recommended controls advised. Below normal 

 rainfall will tend to magnify situation. (Ins.-Dis. Newsltr.) .
