A Review Of The Nearctic Species Of The Thrips-Attacking Genus Ceranisus Walker (Hymenoptera: Eulophidae), S. V. Triapitsyn, David H. Headrick

Horticulture and Crop Science

The thrips-attacking Eulophidae (subfamily Entedoninae) known from the Nearctic region are reviewed. One new species, Ceranisus loomansi, is described. Four other species of Ceranisus are redescribed and illustrated based mainly on a study of their type specimens as well as on additional material from Arizona, California, Hawaii, Mississippi and Japan. Lectotypes are designated for Ceranisus americensis (Girault), C. nubilipennis (Williams) and C. russelli (Crawford). A key to eight species belonging to four entedonine thrips-attacking genera is given, and host associations are indicated for those species.

Incidence And Life History Of Beech Scale, Initiator Of Beech Bark Disease, In The Great Smoky Mountains National Park, Robert Angelo Vance

Masters Theses

American beech, Fagus grandifolia Ehrlich, in eastern North America are currently threatened by the devastating beech bark disease. This disease is caused by the fungal pathogens, Nectria coccinea var. faginata Lohman, Watson and Ayers, and Nectria galligena Bres., which infect trees that are predisposed by infestations of beech scale, Cryptococcus fagisuga Lindinger. In 1993, beech bark disease was discovered in the Great Smoky Mountains National Park (GSMNP).

In 1994, a 2-year cooperative research project involving the National Park Service and the University of Tennessee Agricultural Experiment Station was initiated to study several aspects of beech bark disease in the GSMNP. …

Accuracy Of Equations Predicting The Phyllochron Of Wheat, Gregory S. Mcmaster, Wallace Wilhelm

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Predicting the rate of leaf appearance, or phyllochron, aids in understanding and modeling grass development and growth. Nine equations predicting the phyllochron of wheat (Triticum aestivum L.) were evaluated using field data from a variety of locations, cultivars, and management practices. Each equation is referred to by the last name of the first author; if there is more than one equation by the first author, additional descriptors were included. The BAKER and KIRBY equations predict the phyllochron based on changes in daylength following seedling emergence; CAO-TEMP and CAO-DAY use a curvilinear relationship with temperature and daylength, respectively; CAO-T&D uses the …

United States Patent, Number: 5,466,788: Subgenomic Promoter, Paul G. Ahlquist, Roy C. French

Department of Plant Pathology: Faculty Publications

A subgenomic promoter of a positive strand RNA virus is disclosed which directs the amplified expression of a structural gene in plant tissue. The core region and an upstream activating domain of the subgenomic promoter are identified. This promoter can be utilized in a modified virus, or in an appropriate engineered recombinant DNA derivative, which may be chromosomally integrated or maintained as an episome in transformed cells.

D.Gps For Ground Control In The Quindabellup And Wambellup Sub-Catchments, Buddy Wheaton

Soil conservation survey collection

This report summarises work undertaken to provide ground control for digital terrain models(DTMs) of the Quindabellup and Wambellup sub-catchments. The DTMs will be generated using digital photogrammetry; the ground control was obtained using differential Global Positioning System (D.GPS). Description of Bench Marks (BMs) and summary sheets of Standard Survey Marks (SSMs) located in the general area, were obtained from the Department of Land Administration(DOLA). A ground survey was carried out to confirm the location and condition of BMs and SSMs in the two sub-catchments. Five SSMs were selected as reference points for the D.GPS survey. A further 8 bench marks …

Nitrous Oxide Loss From Poultry Manure-Amended Soil After Rain, Mark S. Coyne, A. Villalba, Robert L. Blevins

Plant and Soil Sciences Faculty Publications

Land application of poultry wastes in Kentucky will increase as the broiler industry grows. If poultry manure stimulates N₂O loss from soil it will reduce the fertilizer N value of this waste. In contrast, stimulated N₂O loss in grass filter strips receiving the runoff from manured fields could help reduce contamination of surface water by NO⁻₃. Our objectives were to determine (i) if poultry manure stimulated N₂O loss in soil after rainfall and (ii) if there was an edge-of-field effect on N₂O loss in grass filters intercepting runoff from …

Remnant Vegetation And Natural Resources Of The Blackwood River Catchment An Atlas, Shaun B. Grein

Agriculture reports

The Blackwood River is one of the longest rivers in the South-West of Western Australia, stretching 300 km from Moordjarrup to August. The catchment covers more than 28,000 square kilometres (2.8 million ha) from the Shire of Kent to the Shire of Augusta-Margaret River. It incorporates 17 shires, more than 30,000 people, 18 Land Conservation District Committees (LCDCs) and 143 sub-catchment groups. Shires within the Blackwood Catchment cover 4.12 million hectares, over half of the total area of the shires that fall within the catchment boundary.

Pb897 Commercial Bush Snapbean Production, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Snapbean production in Tennessee ranges from 6,000 to 9,000 acres and contributes $7 to $9 million annually to the state’s economy. The major production area is located within a 50-mile radius of Crossville, with some early production in the south central portion of the state. Small acreages are grown throughout the state for local sales.

Presently, the acreage is about 45 percent processing and 55 percent fresh market. Fresh market packing operations have increased about five-fold in the last few years.

The varying elevations and temperatures enable producers to plant early at lower elevations and make summer plantings at higher …

Adaptability And Reliability Of Yield For Four Bell Pepper Cultivars Across Three Southeastern States, Laurie Hodges, Douglas C. Sanders, Katharine B. Perry, Kent M. Eskridge, K. M. (Dean) Batal, Darbie M. Granberry, Wayne J. Mclaurin, Dennis Decoteau, Robert J. Dufault, J. Thomas Garrett, Russell Nagata

Department of Agronomy and Horticulture: Faculty Publications

Four bell pepper (Capsicum annuum L.) cultivars were evaluated for yield (total weight of marketable fruit) performance over 41 environments as combinations of 3 years, three planting dates, and seven locations across North Carolina, South Carolina, and Georgia. Cultural practices, including trickle irrigation and double rows planted on black plastic-covered beds, were uniform across all environments, except for fertilization, which was adjusted at each location based on soil tests. Comparing production over 3 years between the mountain location and the Coastal Plain location in North Carolina, yields were lower on the Coastal Plain. Spring plantings provided higher yields than …

A Second Nitrogenase In Vegetative Cells Of A Heterocyst-Forming Cyanobacterium, T Thiel, E Lyons, J Erker, A Ernst

Biology Department Faculty Works

In many filamentous cyanobacteria nitrogen fixation occurs in differentiated cells called heterocysts. Filamentous strains that do not form heterocysts may fix nitrogen in vegetative cells, primarily under anaerobic conditions. We describe here two functional Mo-dependent nitrogenases in a single organism, the cyanobacterium Anabaena variabilis. Using a lacZ reporter with a fluorescent beta-galactoside substrate for in situ localization of gene expression, we have shown that the two clusters of nif genes are expressed independently. One nitrogenase functions only in heterocysts under either aerobic or anaerobic growth conditions, whereas the second nitrogenase functions only under anaerobic conditions in vegetative cells and heterocysts. …

The Vascular Flora Of The Potomac River Watershed Of King George County, Virginia, Mark P. Simmons, Donna M.E. Ware, W. John Hayden

Biology Faculty Publications

The results of two floristic studies of King George County, Virginia, are combined into an annotated checklist. Field work was initiated in 1983-84 with a study of Caledon Natural Area, a 2,500-acre tract with 3.5 miles of frontage on the Potomac River. Collecting resumed in 1991 and 1992 to include other portions of the county drained by the Potomac River. The study area contains a wide variety of habitats including dry upland woods, mesic ravines, low elevation river flats, beaches, swamps, marshes, and creeks; creeks and marshes include both brackish and freshwater environments. The Potomac River watershed of King George …
