Abstract Boxelder bug is an annual house-hold nuisance pest which leaves its host plant in late fall to seek overwintering sites in and around buildings. It is a pest from coast to coast in the United States and southern Canada. Adults for the study were collected from a heavy seeding big-toothed maple in the landscape at Texas A&M Univ. Res. & Ext. Ctr., Dallas, TX. A maple leaf and 3 seeds as food were dipped in the appropriate dilutions of BioCide-TRFTm (Mycotrol GH-ES) Beauveria bassiana (2.0 X 1013 conidia/qt), and placed on two water saturated filter papers (for high humidity) in each feeding chamber in the lab. Five randomly selected adults were introduced into each 9 cm diam X 15 mm deep plastic feeding chambers labeled for respective treatments in a RCB design with 6 replica-tions. Silwet (0.04%) was added to each treatment as a wetting agent to ensure good coverage. The bugs exposed to different treatments were observed daily for mortality; all dead insects were held for several days to confirm the fungus activity indicated by an expression of mycelia from the joints of dead insects.

Abstract Larvae of the fall armyworm annually cause damage to most of the warm-season turfgrasses. Terminal stolons of common bermudagrass were dipped in the appropriate dilutions of BioCide-TRF™ (Mycotrol GH-ES) Beauveria bassiana (2.0 X 1013 conidia/qt), and placed on two water-saturated filter papers (for constant humidity) in each feeding chamber in the lab. Three randomly selected 5-d-old larvae were introduced into each 9-cm-diam. x 15-mm-deep plastic feeding chambers labeled for the respective treatment in a RCB design with 7 reps. Silwet (0.04%) was added to each treatment as a wetting agent to ensure good coverage. Treatments were observed daily for mortality.

Phosphate Compounds

Environmental context. Contamination of groundwater and sediments by heavy metals and radioactive metals is a significant problem within the United States Department of Energy complex as a result of past nuclear operations. One way to remediate these metals is through reaction with phosphate compounds, which can immobilise the metals by forming highly stable metal phosphate compounds. Long-chain, water-soluble phosphate compounds provide a means to inject phosphate into subsurface contaminant plumes, to precipitate metal ions from solution. Results presented here illustrate that application of a soluble sodium tripolyphosphate to sediment contaminated with uranium will rapidly reduce the concentration of uranium in the pore water to concentrations near or below drinking water limits under water-saturated and unsaturated conditions. Abstract. A series of conventional water-saturated and pressurised unsaturated flow column experiments were conducted to evaluate the effects of using soluble polyphosphate amendments for in-situ, subsurface remediation of uranium. Experiments were conducted under mildly alkaline, calcareous conditions, representative of conditions commonly encountered at sites across the arid western United States. Results presented here illustrate that application of a soluble polyphosphate amendment to sediment contaminated with uranium will rapidly reduce the concentration of uranium released to the porewater to near or below drinking water limits under water-saturated and -unsaturated conditions. Column experiments conducted in the absence of polyphosphate illustrate sustained release of aqueous uranium at concentrations well above drinking water standards in excess of over 25 pore volumes under water-saturated conditions and over 50 pore volumes under unsaturated conditions. In the presence of tripolyphosphate, the concentration of aqueous uranium released from the sediment was below drinking water limits within 10 to 35 pore volumes under water-saturated and unsaturated conditions, respectively. Moreover, results indicate the necessity of conducting site-specific dynamic tests to tailor phosphate-based remediation technology to site specific geochemical and hydrological conditions.

Danausplexippus L. (Lepidoptera: Nymphalidae) is a cosmopolitan species, distributed in America wherever milkweed grows (Amett 1985). Its migratory phenomenon spans Canada, the United States, and Mexico and it has been considered endangered since the 1980s (IUCN 1983).Ackery and Van-Wright (1984) compiled 45 species of food plants used by immature stages and 70 species of plants attractive to adults of the Monarch butterfly. Malcolm and Brower (1986) listed 28 host plant species recorded in nature. Lynch and Martin (1993) added six Asclepias species and observed larvae on three species of milkweed vine, Sarcostemma crispum and S. cynancroides in Texas, and Cynanchum laeve in Louisiana.

AbstractThe taxonomy of the Nearctic genus Ophraella Wilcox is revised. Data for all known immature stages are included. Ophraella integra (LeConte) is synonymized with O. notulata (Fabricius). Ophraella dilatipennis (Jacoby) is transferred to the genus Neolochmaea Laboissière.Thirteen species are recognized, of which 6 are new : O. arctica, californiana, communa, macrovittata, nuda, and pilosa. The distribution and host plants of species are as follows : O. americana, eastern North America, on Solidago spp.; O. pilosa, transcontinental along the Canadian border, on Aster, primarily A. macrophyllus; O. cribrata, coast to coast in the United States, on Solidago of the subgenus Virgaurea; O. conferta in northeastern states, on Solidago with preference for S. canadensis and S. rugosa; O. sexvittata in southeastern states, on Solidago spp.; O. notulata in eastern US and Gulf states to Mexico, on Iva oraria; O. notata in eastern portion of the United States, on Eupatorium perfoliatum; O. macrovittata in the Gulf states, host plant unknown; O. communa in North America and Mexico, on Ambrosia artemisiifolia; O. bilineata in the Canadian Prairies and the bordering states, on Chrysopsis villosa; O. californiana in California and Mexico, on Artemisia Douglasiana; O. nuda in Alberta, host plant unknown; and O. arctica in tundra zone, on Solidago multiradiata scopulorum.The life cycles of most species are still unknown but most species probably have only 1 generation per year. The eggs are laid in clusters on the under surface of young leaves. The larvae skeletonize young leaves and live exposed. Before pupation, the larva spins a loose cocoon and attaches it to a leaf tip. Pupation lasts 1–2 weeks. The newly hatched adults are active on host plants until the early fall, when they enter the leaf litter for overwintering.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Communities Of Interest

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
