Above normal temperatures are indicated for the eastern two-thirds of the Nation except for near normal temperatures in New England. The most unseasonable warmth is expected over the southeastern quarter of the Nation. Precipitation is expected to exceed normal over the western two-thirds of the country except for near normal in the west coast States. Sub-normal amounts are predicted for the Atlantic Coast States. Elsewhere near normal totals 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.

These are first larvae reported this season. (McQueen). TOBACCO BUDWORM (Heliothis virescens) - FLORIDA - Larvae 1 per 7-8 plants of flue-cured type tobacco in field plots at Gainesville, Alachua County, April 5. (Kuitert). Early instar larvae, 1-3 per plant at 2 locations in Alachua County April 13. Moderate to heavy larval populations on newly set flue-cured tobacco in Lafayette County during early April. (Strayer).

(Kurtert, April 5) GREENBUG (Schizaphis graminum) - OKLAHOMA - Decreasing very rapidly in all areas; problem only in Scattered fields in extreme northern part of State. Predators and parasites controlling infestations. (Okla. Coop. Sur.). KANSAS - Trace still present in many northeast wheat fields. (Simpson). MISSOURI - Still found in all small grains. Ranged 25-300 per foot of row in southeast and east- central areas. Wheat beginning to head in extreme southeast area. (Munson). NEBRASKA - Surveys negative in wheat in Keith County. (Rhine). SPOTTED ALFALFA APHID (Therioaphis maculata) - NEVADA - Medium in a field in Moapa Valley, Clark County. (Zoller). NEW MEXICO - Appearing light on alfalfa in Eddy County. (Mathews). KANSAS - Trace, 0-2 per 10 sweeps in 2 alfalfa fields checked in Brown County. None elsewhere in northeast district. (Simpson).

Second Beet Leafhopper Survey in Desert Areas of Central Arizona, Southeastern California, Southern Nevada, and Utah: March 20-27, 1967. Additional buildup of beet leafhopper (Circulifer tenellus) is expected in areas north of the 34° parallel. These areas include Southern Nevada and Utah and parts of California and Arizona adjacent to the Colorado River. Additional beet leafhoppers are expected to mature because host plants, which remained green despite unseasonably dry and hot weather, revived under recent rains. South of the 34° parallel, however, similiar dry weather conditions stunted host develop- ment. Movement to cultivated areas is expected to be light to moderate in central Arizona, southeastern California, and western Nevada; moderate to heavy - 304 - in southern Nevada, southern and eastern Utah, and western Colorado; light to moderate in central Utah; and light in northern Utah. For results of preliminary survey see CEIR 17(9):131. Potato Psyllid Survey, Spring Breeding Areas of Arizona and California - 1967 The 1967 survey for potato psyllid (Paratrioza cockerelli) in the overwintering areas of Arizona and California was conducted March 30-April 3.

Potato psyllid populations were low, averaging 8 per 100 sweeps in the Blythe-Barstow area to 34 per 100 sweeps in the Tucson-Phoenix area.

The Western Plains, critically dry for several weeks, received moderate to heavy rains over very large areas. PRECIPITATION: A well-developed storm brought heavy snow to the southern and central Rocky Mountains and copius rains from the eastern Slopes to the Ohio River Valley. Flagstaff, Arizona, received 16 inches of Snow on Wednesday; by Friday the snow had accumulated to 36 inches in parts of Colorado. Some of the heaviest rains fell in south-central Oklahoma, an area which had been very dry a few weeks ago. The storm failed to provide appreciable rain to New Mexico and extreme western Texas but, as the cold front moved southward, it set off heavy thunderstorms and a few tornadoes in the lower Mississippi Valley. On Friday, about 11 inches of rain fell at Baton Rouge, Louisiana, in 9 hours, causing considerable flooding. Scattered tornadoes occurred from Kansas and Missouri southward to Mississippi at midweek and from Iowa and Illinois to Wisconsin and Michigan on Friday but damage was not extensive. Moist Pacific air brought more than 2 inches of rain to the Washington and Oregon coast with lesser amounts in- land and over California and Arizona. Much of the Great BaSin and the southern deserts received no rain, or only light sprinkles. Strong gusty winds raised clouds of dust in the dry areas of New Mexico. Another area that received no rain was southern Florida where precipitation Since March 1 has been less than a fourth of normal. TEMPERATURE: Temperatures averaged below normal west of the Continental Divide and over New England and warmer than normal elsewhere. Much of the middle part of the country averaged 5° to 8° warmer than seasonal. In general, it was the third cool week in the far West, the fourth warm week in the north-central area and the seventh warm week over the Southeast. Afternoon temperatures continued in the 80's over the Gulf States but cool air from Canada held afternoon maximums farther north to the 40's and 50's early in the week with minimums dropping to freezing or lower as far south as the Ohio River and the southern Appalachians. By the weekend, maximums had climbed to the 80's as far north as eastern Pennsylvania. In the west, minimums dropped to below freezing over the Great Basin and the Rocky Mountains. Northern Arizona and northern New Mexico regis- tered minimums in the 20's on 1 or 2 days. Maximums ranged from the 50's in Washington to the 80's in southern Arizona and New Mexico.

CITRUS RUST MITE (Phyllocoptruta oleivora) populations will continue abnormally high despite decreases in April and May. Fruit will become infested earlier and heavier than usual. A strong June increase is expected. TEXAS CITRUS MITE (Eutetranychus banksi) population will be above average. It will hold near current moderate Level through April and then increase rapidly into the high range in May and June. Scattered heavy infestations of CITRUS RED MITE (Panonychus citri) will occur in about 10 percent of groves during April and May. A rapid increase in June is expected in a majority of groves.
