West of the Divide below normal averages are anticipated. Precipitation is expected to exceed normal west of the Divide except for near normal amounts in the Southern Plateau Region. East of the Divide above normal amounts are called for from the Northern Plains eastward over the Upper and Middle Mississippi Valley to the Great Lakes Region and the Ohio Valley. Subnormal amounts are anticipated over the Middle and North Atlantic Coastal Region as well as over the Southern Plains, Near normal amounts are expected in unspecified areas, Weather forecast given here is based on the official 30-day "Resume and Outlook" published twice a month by the Weather Bureau.

Heavy thundershowers occurred in the lower Mississippi River Valley and some heavy rains in southern California, TEMPERATURE: Temperatures over the Rocky Mountains and the northern and central Great Plains averaged from 20° to 30° warmer than the previous week. A few stations in Montana, Wyoming, and South Dakota averaged more than 30° warmer. Increases in average temperature in Texas ranged from 7° at Galveston to 19° at Wichita Falls. Slight increases occurred along the Ohio River. Minnesota averaged about 20° warmer. Temperatures south and west of a line from northern Montana to Jacksonville, Florida, averaged above normal; below normal tempera- tures prevailed elsewhere, PRECIPITATION: A wide area from Montana and North Dakota to the middle Rio Grande Valley received no precipitation beyond light sprinkles or snow flurries. Scattered areas in the South and Southeast received substantial rains from thundershowers. One such area extended from Springfield, Missouri, to Nashville, Tennessee, and another from Shreveport, Louisiana, to Jackson, Mississippi. Some parts of Texas, such as at San Antonio and Waco, received more than 2 inches of rain. The eastern half of the Nation received precipitation early in the week while the northern and central Plains and the Southwest and Southeast received precipitation later on, Rains occurred over most of California on Wednesday, Thursday, and Friday, and continued in the south portions Saturday and Sunday. Parts of southern California received more than 2 inches and a few desert locations in one week received the equivalent normal amounts for a 7-month period. Heavy snow fell in some western mountains near the end of the week, and Flagstaff, Arizona, accumulated snow to 13 inches.

Wherever possible, samples were taken from the same locations that were sampled in the fall of 1964. The number of live boll weevil (Anthonomus grandis) adults per acre of ground trash examined and the percent survival are reported in the following paragraphs. For details of the fall (1964) hibernation survey in these five States, see CEIR 15(1):10-12. In NORTH and SOUTH CAROLINA, samples were taken during the period March 9-18 in the same three representative areas in which fall examinations were made in 1964. In each area, a total of 30 locations (farm sites) was sampled with 3 samples from each location. The areas are as follows: South central South Carolina (Orangeburg, Dorchester and Bamberg Counties), Coastal Plain of South and North Carolina (Florence, Darlington and Marlboro Counties, S.C., and Scotland County, N.C.), and north central North Carolina (Nash, Wilson, Franklin and Edgecombe Counties). The average number of live weevils per acre in these areas was 1,855, 10,164 and 1,371, respectively. The percent survival for these areas was 24.2, 66.9 and 41.4, respectively. The percent survival was lowest in south central South Carolina and was highest in the Coastal Plain of South and North Carolina. In Florence County, South Carolina, an average of 14,795 weevils per acre was found for the spring of 1965 with a winter survival of 83.1 percent. The number of weevils surviving in Florence County is 5.7 times the number surviving in 1964, (Taft, Hopkins). Spring trash examinations were made in ALABAMA from March 1 to April 2 in 3 of the 4 counties surveyed in the fall of 1964. Examinations in Dallas County are to be completed at a later date. The number of live weevils per acre in the 3 counties completed was 162 in Morgan County, 3,230 in Henry County and 1,080 in Tuscaloosa County. Survival counts are considerably higher than in 1964. The more important observation is that an average of 162 live weevils survived per acre of surface trash in Morgan County, compared with zero in 1964. Collections were started on February 24 in MISSISSIPPI and all examinations were completed on March 11. Three samples were taken from each location and either 7 or 8 locations were sampled in each county. Four counties made up each area and the State was divided into four areas as follows: Area 1 - lower delta (Sharkey, Issaquena, Yazoo and Humphreys Counties); Area 2 - central delta (Washington, Bolivar, Sunflower and Leflore Counties); Area 3 - north delta (Coahoma, Tunica, Quitman and Panola Counties); Area 4 - hill section (Holmes, Madison, Noxubee and Monroe Counties). Ninety samples were taken from a total of 30 locations in each of the four areas. The average number of weevils found per acre in Areas 1, 2, 3 and 4 was 1,129, 1,640, 296 and 914, respectively. The State average was 995 compared with 289 in 1964, 13 in 1963, 1,132 in 1962, 1,246 in 1961, 821 in 1960, 464 in 1959, and 392 in 1958. The percent survival in Areas 1, 2, 3 and 4 was 17.80, 31.28, 8.73 and 30.91, respectively. The State average (percent survival) was 22.19 compared with 9.68 in 1964, 0.2 in 1963, 13.59 in 1962, 8.59 in 1961, 16.23 in 1960, 12.22 in 1959 and 6.65 in 1958. (Pfrimmer). In central TEXAS, spring collections were made March 4-11. Three samples were taken from each location and 6 or 7 locations were sampled in each county. The average number of weevils found per acre in Falls, Hill, Limestone and McLennan Counties in the spring of 1965 was 3,629, 3,360, 5,502 and 6,785, respectively, with an area average of 4,925. This compares with 2,285, 2,957, 5,502 and 6,640 found in these respective counties in the fall of 1964, with an average of 4,406 weevils per acre for the area. The survival percent was 100. This compares with survival counts of 31.1, 33.7, 33.1, 25.4 and 18.8 percent in March of 1960, 1961, 1962, 1963 and 1964, respectively. The increase in numbers of boll weevil entering hibernation in the fall of 1964 was due primarily to late stalk destruction and farm cleanup. This resulted in more weevils being = 313 = found in the fall inspections than in the previous 4 years. The indicated spring survival was extremely high. More weevils were found in the spring of 1965 than in any year since trash examinations were started. More weevils were found in Hill, Falls and McLennan Counties in the spring of 1965 than in the fall of 1964. The same number of weevils was found in Limestone County this spring as were found last fall. (Cowan).
