 | We compared 6 adult mosquito traps for effectiveness in collecting Aedes albopictus from suburban backyards with the goal of finding a more suitable surveillance replacement for the Centers for Disease Control and Prevention (CDC) light trap. Trap selection included 2 commercial propane traps (Mosquito Magnet(TM) Professional trap and Mosquito Magnet Liberty trap), 2 Aedes-specific traps (Fay-Prince Omnidirectional trap and Wilton trap), 1 experimental trap (Mosquito Magnet-X trap), and a standard ... |

|
| Protecting the Nation's agriculture and food critical infrastructure and key resources (CI/KR) is an important responsibility shared by Federal, State, local, and tribal governments and private industry. Because of the open nature of many portions of the Food and Agriculture Sector, attacks against the Nation by using food or agricultural infrastructure or resources as weapons could have a devastating impact on public health and the economy. Traditional physical security practices ... |

Gary R. Beecher; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| Endogenous estrogens are thought to have a role in the etiology of breast cancer. Several components of plant foods have estrogenic activity or are metabolized to active compounds by mammalian systems (phytoestrogens). The impact of these constituents on breast cancer risk is unknown because of the lack of databases containing appropriate values for foods. The goal of this research is to provide a database of values for the various isoflavones ... |

| We examined the effects of high energy expenditure and hypocaloric intakes during US Army Ranger training on cellular immune functions and systemic cytokine production. Blood samples were collected at baseline (B), and at the end of each of 4 phases, (Benning, I; Mountain, II; Jungle, III; Desert, IV), of training. Mitogen induced T-lymphocyte proliferation was suppressed at the end of Phases I-IV, with the greatest at the end of II ... |

|
| As part of the AgRISTARS (Agriculture and Resources Inventory Surveys through Aerospace Remote Sensing) DCLC (Domestic Crops and Land Cover) project, the Remote Sensing Branch (RSB) of the Statistical Reporting Service (SRS) is investigating the operational use of LANDSAT data in an applied research mode. Currently, six States (Kansas, Missouri, Oklahoma, Illinois, Colorado, and Iowa) are participating in the project. The primary objective is to provide timely, more precise crop ... |

B. E. Spiers; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| The purpose of this paper is to describe how the Foreign Agricultural Service (FAS) of the USDA utilizes remotely sensed satellite data in the assessment of crop conditions for selected crops in some areas of the world. The Foreign Crop Condition Assessment Division (FCCAD) is part of the Office of International Agricultural Statistics which has the responsibility within USDA for producing foreign crop production estimates. After five years of developmental ... |

B. F. Kukachka; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| Consisting of about 32 neotropical species, the genus Manilkara has a widespread distribution in the Americas ranging from southeastern Brazil and northern Bolivia as far north as southern Florida. It is probably the most important of the American genera, being the source of commercial timbers, fruits, and gums. Manilkara, as constituted here, consists of a generic complex that includes Achras, Muriaeanthe, Schaferodendron, Manilkariopsis, and Chiclea. This 'complex' exhibits remarkable anatomical ... |

E. B. Alexander; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| Analyses of 721 samples from inorganic horizons of upland and alluvial soils in seven orders were utilized to develop equations for predicting soil bulk density at 1/3-bar water content. The minimum standard errors of estimate (0.14 g cucm, r sq = 0.723, for upland soils and 0.11 g/cucm, r sq = 0.672, for alluvial soils) were obtained with functions of organic carbon content; 15-bar water content, the ration of 15-bar ... |

Keith R. Cooley; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| A method was developed for determining the erosive power, R sub st, of individual rainfall events of any selected frequency and duration for any of the four SCS type storms. The method provides an easy, rapid procedure for assessing erosion or pollution potential on a storm basis, since sediments themselves are pollutants and are carriers of chemical pollutants. It also allows designers of conservation measures to determine the range of ... |

|
| The size of distribution of soil particles detached and transported in rill and interrill flow was determined on a silt loam soil in northcentral Indiana. Eroded soil was separated by field and laboratory sieving. The amount of primary clay transported as discrete particles in rill and interrill flow was also determined. Large differences were found in the size of soil aggregates and primary particles in rill and interrill sediment. Rill ... |

| Plinthic Paleudults of the clayey-skeletal family are on the highest uplands. Compared to the other Paleudults, they are more clayey, and have higher amounts of extractable iron, and contain high amounts of ironstone concretions. The argillic horizons have 0.3 meq of Ca 2 + and Mg 2 + or less per 100 g of soil. Because of the gravel, these soils are best suited to rubber or cashews. The loamy ... |

M. J. Lindstrom; S. C. Gupta; C. A. Onstad; W. E. Larson; R. F. Holt; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| We calculated potential soil erosion by water for major land resource areas (MLRAs) in the Corn Belt using the universal soil loss equation and current cropping practices. Annual erosion rates ranged from 44.7 metric tons per hectare (19.9 t/a) in MLRA 107 to 9.7 metric tons per hectare (4.3 t/a) in MLRA 103 for a conventional fall-plow, spring-disk tillage system with all residues removed. With no conservation practices applied, only ... |

| Authors:
R. B. Campbell; T. A. Matheny; P. G. Hunt; S. C. Gupta; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| We calculated the crop residues needed for water erosion control in 6 southern states. Six crop sequences were evaluated in each of 14 major land resource areas (MLRA). In 13 of 14 MLRAs, weighted average estimated soil loss exceeds tolerable limits. The exception is MLRA 153, Atlantic Coastal Flatwoods, where the greatest percentage of residues remains available after water erosion control needs are met. In all MLRAs, conservation tillage significantly ... |

R. R. Allmaras; S. C. Gupta; J. L. Pikul Jr.; C. E. Johnson; DEPARTMENT OF AGRICULTURE WASHINGTON DC
|
| We estimated soil erosion by water in the major land resource areas (B7, B8, B9) of eastern Oregon. Combinations of tillage and crop residue handling, terracing, and contouring were evaluated as control alternatives. Wheat-fallow, especially, and wheat-pea sequences predominated. Soil erosion exceeded tolerance limits in the wheat-fallow sequence on slopes over 20% even with all 3 management inputs. All 3 management inputs were needed on slopes between 12 and 20%. ... |

|
| Simulated rainfall was used to determine the erosion control effects of portland cement on upland soils. Treatments included four rates of cement application and two methods of cement incorporation on two medium-textured soils. The application of 2.50 metric tons of portland cement per hectare (1.1 tons/acre), applied as a suspension on a tilled slope of moderate steepness and length, nearly eliminated soil erosion. Lower rates of cement application proved ineffective ... |
