Above-normal temperatures are predicted along the West Coast and near normal in the remainder of the country. Rainfall is expected to be greater than normal in the northern third of the Nation east of the Continental Divide, and also along the Gulf and South Atlantic coasts. Subnormal amounts are indicated in both the Southwest and Pacific Northwest. In areas not specified, near normal amounts are in prospect. Weather forecast given here is based on the official 30-day "Resume and Outlook," published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING MAY 2 Sharply contrasting air masses left weekly temperatures generally below normal from the Pacific coast eastward to the western Great Lakes, the central Mississippi Valley, and Texas and generally above normal in the eastern third of the Nation. Departures were as much as 12° or more below normal in parts of Montana and north-central Nebraska, and 6° above normal near the Nation's Capital. Polar air moved eastward late in the week to cover most of the Eastern States, however, dropping temperatures sharply from the record or near-record early season levels reached earlier. Freezing temperatures late in the week extended southward to northwestern Texas. Moderate to heavy precipitation in California greatly benefited crops there. Over the Plateau States, scattered moderate to heavy rain or snow improved soil moisture conditions, and in the Great Plains and Mississippi Valley precipitation ranged from moderate to heavy. In northern sections, snowfall was mixed with showers and general rains. Locally heavy snow fell in eastern Colorado, Nebraska, and South Dakota. Water totals ranged from over 1 inch in parts of Colorado to generally 0.50 to 1.00 inch in Nebraska, western Iowa and Minnesota to near 0.50 inch in the Dakotas. Heavy precipitation from Texas, Oklahoma, and Louisiana to Wisconsin, and in the central Mississippi Valley was the result of widespread thunderstorms, and several severe squall lines moved over portions of this region. Heavy hail and damaging winds were reported in the southern Great Plains, and several tornadoes skipped across Oklahoma. Precipitation totals ranged up to 7 inches locally in south- central Texas, over 5 inches in Louisiana, and 4 inches in Oklahoma and Missouri. Rainfall in the Southeast, Middle Atlantic, and New England States was highly variable, ranging from very light to heavy in showers and thunderstorms. Excessive rains in southeastern Florida have caused damage to the vegetable crop, but many sections of the Southeast need additional rain. (Summary supplied by U. S. Weather Bureau). - 349 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - OKLAHOMA - First-instar nymphs of Melanoplus sp. noted in limited numbers, less than 1 per square yard, on 2 rangeland areas checked in Rogers and Nowata Counties.

The first record of the pest in the United States was at Ames, Iowa, on June 18, 1929. The insect was probably introduced into the United States as eggs in packing material, as about 700 seed samples were imported and grown at the agronomy farm at Ames in 1926 and 1927. Alfalfa plant bug can be very destructive to alfalfa seed. During 1955 in Illinois, counts of the species reached as high as 440 per 100 sweeps in some alfalfa fields; and im southeastern Nebraska in 1956, nymphs of this pest could be collected at the rate of 40 to 50 per 10 sweeps during early June. Distribution: Algeria, Austria, Canada, China, Finland, France, Germany, Great Britain, India, Iran, Japan, Sweden, Tunisia, United Arab Republi¢ (Syria) , USSR (including Siberia) and the United States (see map). Hosts: Alfalfa and sweetclover are the preferred hosts. A limited number of other legumes and many succulent herbaceous plants, such as, chrysanthemum, thistle, beets, sugar beets, cotton, castorbean, potato and buckwheat, are recorded hosts. Life History and Habits: Alfalfa plant bug prefers to feed on flower buds and newly formed seeds of host plants. Feeding injury is believed to be phytotoxic. The pest also injures the plants in oviposition and is attracted to lights at night. Only two generations occur in the latitude of St. Paul, Minnesota, and these overlap considerably. Alfalfa plant bug overwinters in the egg stage in Minnesota and other forms are killed with the advent of cold weather. Overwintering eggs are laid singly in the less-succulent stems near the soil surface of the host plants and begin hatching by the middle of May the following year. Nymphs pass through 5 instars in approximately 30 days. In two weeks adults begin to lay eggs, as early as June 22. Thus there is a second generation by late August or early September in Minnesota. DISTRIBUTION OF ALFALFA PLANT BUG (Adelphocoris lineolatus) Map compiled in i aa BS \ i Survey and Detection Operations, PPC, ARS, USDA, » Say from State reports received to January 1, 1960, low ARS and USNM records eae « - 370 - Description: EGG -Length 1.36 mm. and 0.33 mm. at greatest diameter. Clear when first laid, yellowish when older; slightly curved, thickest near base, compressed at apex and obliquely truncate. NYMPH - Fifth instar - Length 5.5 mm., width 2.4 mm. Color uniformly yellowish-green, third and fourth antennal segments reddish-brown, tips of wing pads becoming uscous. Legs uniformly pale yellowish and marked with black spots as in the adult. Dorsum and legs set with short, stiff black setae, antennae clothed with black pubescence. ADULT - Male - Body 8 mm. long, 2.8 mm. wide. Head 1.36 mm. wide, vertex 0.42 mm. Antennae 7.35 mm. long; first segment 0.98 mm., second 2.87 mm., third 2.20 mm., and the fourth segment 1.30 mm. long. Pronotum 1.30 mm. long and 2.25 mm. wide at base. General coloration pale yellowish with a tinge of brown and dusky. Scutellum with two fine, longitudinal, fuscous marks on middle; corium usually with triangular fuscous area on apical half; a fine line along costal edge black; cuneus yellowish; membrane fuscous. Antennae yellowish to brown, apical half darker and usually reddish-brown. Legs yellowish; femora with many black dots, anterior aspect with two rows of somewhat larger spots; tibial spines black, without distinct spots at bases. Body clothed with simple, pale yellowish pubescence; legs with black pubescence. Female - Body 7.50 mm. long, 2.90 mm. wide. More robust than male and usually somewhat paler in color, but otherwise very similar in form and coloration. Alfalfa plant bug can be separated from rapid plant bug (A. rapidus) by its paler color and slightly larger size. (Prepared in Survey and Detection Operations in cooperation with other ARS agencies).
