A cold front brought a pleasant weekend to the Central and East following several days of unusually hot humid weather, PRECIPITATION: Heavy rains fell early in the week along a front that extended across our northern border States from the western Great Plains to New England. Numerous tornadoes and violent thunderstorms occurred from South Dakota and Iowa to Lower Michigan. Most of the tornadoes struck rural areas. A few farmsteads suffered damage to buildings and trees. Besides the heavy showers that accompanied the violent thunderstorms and tornadoes along the front, airmass thunderstorms developed in the hot,humid air south of the front. The showers were mostly light producing an inch or less of rain. In some areas, rainfall ranged from 1 to 2 inches and widely scattered storms dropped several inches in Short time intervals. On Thursday, a severe thunderstorm at Burlington, Vermont, dropped hail up to 3 inches in diameter and the wind at Blue Hill Observatory, Milton, Massachusetts, gusted to 90 m.p.h. Heavy downpours fell Friday night in southeastern Nebraska, eastern Kansas, southwestern Missouri, and northern Arkansas with spots recording 4 to 5 inches of rain by Saturday morning. Little or no rain fell in the Far West. Forest fire danger increased in Washington and lightning started hundreds of fires in Oregon. Dust storms occurred in the irrigated valleys of southern Arizona, TEMPERATURE: Through most of the week, sweltering heat and high humidity main- tained a firm grip over most of the Nation from the Rocky Mountains to the Atlantic coast. Cool weather occurred only along our northern border north of the quasi-stationary front that stretched from Montana to Maine. In some eastern areas, last week was the hottest of the season. In North Carolina, it was the hottest week in almost 2 years. Beloit, Wisconsin, registered 100° on Thursday, the first time in Several years that the temperature has gone so high anywhere in the State. Temperatures reached 100° to 105° on several afternoons from Southern South Dakota to northern Texas. The front began moving late in the week and by the weekend, a broad stream of cool,dry air was bringing unseasonably cool weather and clear skies to much of the central and eastern portions of the Country. Numerous locations in the Northeast registered temperatures in the 40's early Monday morning, August 12. The Far West continued warm to hot throughout the week. The Rocky Mountains and western Plains averaged cooler than normal. Most of the East averaged warmer than normal in spite of the weekend temperature drop. (Summary Supplied by Environmental Data Service, ESSA.) - 781 - SPECIAL INSECTS OF REGIONAL SIGNIFICANCE GREENBUG (Schizaphis graminum (In broad sense))* - SOUTH DAKOTA - Destroyed 120 acres of sorghum-Sudan crosses 2-3 inches high near Lesterville, Yankton County. Damaged sudan and crosses of sorghum and sudan in Moody, Turner, Yankton, and Hutchinson Counties. Ranged 4,500-5,000 per plant on some sorghum. Killed several fields of sorghum and sorghum crosses near Parkston, Hutchinson County. Predators light in those fields surveyed. (Jones, Kantack). NEBRASKA - Infesta- tions declined Sharply in eastern area due to parasitism. Parasites destroyed up to 95 percent of aphids in 2 Saunders County fields August 6. (Roselle). Still high on untreated sorghum near North Platte, Lincoln County; ranged 1,600-2,300 per leaf August 8. Predators and parasites increasing slowly. (Staetz). KANSAS - Infesting most sorghum fields throughout State. Damaging numbers in many fields; up to 2,000 per leaf. Severely damaging late-planted fields. In most areas, populations continue to increase except in occasional heavily infested fields where predators and parasites established. Parasitism ranged 25-50 percent in one heavily infested field in Pottawatomie County. (Brooks et al.). OKLAHOMA - Continues heavy in sorghum in Texas, Cimarron, and Beaver Counties. Counts range 1,500-5,000 per plant on leaves, up to 50 per head on plants with heads. Many fields being sprayed. Young sorghum plants and volunteer small grain plants killed in many areas. Also reported causing severe damage to broomcorn in Cimarron County. High counts also reported from Harper, Woodward, Ellis, Beckham, Washita, Blaine, Jackson, and Marshall Counties, Parasites and predators active in west-central and southwest areas and in Payne County; appear _ to be causing some decrease in numbers. Survey Shows only occasional fields lightly infested in Noble, Kay, and Grant Counties. (Okla. Coop. Sur.). ARIZONA - Unidentified aphid generally heavy on sorghum in most areas of Cochise County; controls applied. (Ariz. Coop. Sur.). TEXAS - The aphid is a serious problem on sorghum in the Panhandle and parts of Rolling Plains. Widespread treatment is being carried out. (Green). Normally, greenbug does not cause serious damage to sorghum in this country. The aphid generally does not reproduce after temperatures reach 90° or higher. However, infestations in this outbreak became worse between June and the latter part of July. USDA and State officials will meet at Fort Collins, Colorado, August 15- 16 to discuss current and future plans to combat greenbug outbreaks on sorghum. ARS, in cooperation with affected States, is studying the biology of the pest on sorghum and conducting aerial insecticide tests. (ARS) For previous reports on sorghum see notes carried under greenbug in CEIR 17(37):847, 18(22):461, 18(23): 485, 18(24):509, 18(26):573, and 18(31):722. (PPC).

SMALL FRUITS BRAMBLEBERRY LEAFHOPPER (Macropsis fuscula (Zetterstedt)) - WASHINGTON - Heavy infestation found on Rubus sp. at two locations on McChord Air Force Base, Pierce County, July 24, 1968. Collected and determined by S. Nakahara, Plant Quarantine Division, ARS. Confirmed by J.P. Kramer. This is a new United States record. An outbreak of this leafhopper was discovered on loganberry on Lulu Island, Brit- ish Columbia,in 1952. Heavy infestations have occurred in the Lulu Island area Since 1952 causing considerable damage to various brambleberries through feeding on flowers and fruit and through heavy honeydew deposits, Infestations have been difficult to control. This insect assumed a more important economic status when it was shown to be the vector of the destructive Rubus stunt virus of Europe in 1953. This virus is not known to occur in North America. M. fuscula infests Rubus spp. and occurs in several countries of Europe as well as in British Colun- bia, Canada. The insect overwinters in the egg stage in canes of wild and culti- vated Rubus spp. Eggs hatch in late May in British Columbia, about the time loganberries begin to blossom. ‘Nymphs are numerous by mid-June. There are 5 instars, each stage requiring about 10 days. Adults appear in midsummer. There is apparently only one generation a year. In the Netherlands, the virus is spread from old to new berry plantations by adults. For additional details see CEIR 9 (12): 209-210.
