Records For The Utilization Of Prunus As A Larval Foodplant By 71 Species Of Lepidoptera In Northeast California, Laurence L. Crabtree, Ron Leuschner

The Taxonomic Report of the International Lepidoptera Survey

Twenty-six sites in five northeastern California counties (Shasta, Modoc, Plumas, Lassen, Tehama) were surveyed from 1991 to 1999 for the presence of lepidopteran larvae on naturally occurring shrubs of the genus Prunus. To date, a total of seventy-one species of Lepidoptera from seventeen families have been documented to utilize one or more of the area’s three Prunus species (P. emarginata, P. subcordata, and P. virginiana var. demissa).

Nine New Species Of Lacinipolia (Noctuidae) From Arizona, California And Vicinity, Charles L. Selman, Ron Leuschner

The Taxonomic Report of the International Lepidoptera Survey

This article formalizes the taxonomic conclusions of the senior author’s 1975 successful doctorate dissertation. The nine new species defined in that 1975 dissertation are here formally described in compliance with the rules of the International Code of Zoological Nomenclature (ICZN). The authors have essentially abstracted the original 447 page dissertation and designated types. The new Lacinipolia species are: delongi, aileenae, triplehorni, bucketti, baueri, sharonae, martini, fordi, and franclemonti. The purpose of this paper is simply to make these names available to the scientific community and professional researchers by making them ICZN-compliant.

Cooperative & Nebraska “Blue Sky” Statutes, J. David Aiken

Cornhusker Economics

Cooperative fever is sweeping Nebraska. Agricultural producers are looking for ways to add value to what they produce, often through forming “new generation” cooperatives or by forming limited liability companies (LLCs). New generation cooperatives differ from traditional cooperatives in that new generation cooperatives typically (1) have closed membership and (2) process goods produced by co-op members. New generation cooperatives are more like citrus and other fruit cooperatives that have existed in other parts of the country. The Nebraska Unicameral is providing financial assistance to assist developing these kinds of value-added efforts through LB1348, the “Agricultural Opportunities and Value-Added Partnerships Act.” …

A Taxonomic Study Of, And Key To, The Lecithoceridae (Lepidoptera) From Guizhou, China, Chunsheng Wu

The Taxonomic Report of the International Lepidoptera Survey

This paper provides a key to twelve species (in ten genera and three subfamilies) of Lecithoceridae from Guizhou Province, China. Among them, three species are unnamed and eight are new Guizhou Province records. The female of Opacoptera ecblasta Wu is known for the first time and its genitalia are illustrated for the first time.

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The biology and life history of Celastrina neglectamajor is described. This lycaenid butterfly was first described from West Virginia, United States by 19th century lepidopterist, William H. Edwards, as a redescription of Lycaena pseudargiolus (Boisduval & Le Conte). Edwards provided evidence of its unique late spring flight, Appalachian affinity, and larval host Cimicifuga racemosa (Ranunculaceae). Edwards and subsequent authors, most notably Samuel Scudder of New England, treated it as an infrasubspecific form of the common eastern Celastrina ladon. In 1908 Tutt applied the form name neglectamajor, describing it from one of Edwards’ 1884 figures. For nearly a century, …

Amartya Sen And World Food Day 2000, Bettina Klaus

Cornhusker Economics

As every year, World Food Day took place on October 16th. Being relatively new to UNL (and the U.S.), and being an assistant professor in the Economics Department (joint with the Agricultural Economics Department) with research interests in social choice and game theory, the probability that I would get involved with World Food Day were slim. However, somehow it caught my eye that the yearly teleconference that accompanies World Food Day featured the 1998 Nobel prize winner for economics, Professor Amartya Sen. The 2000 World Food Day’s teleconference topic was “Poverty and Hunger: The Tragic Link” and in a superb …

Faculty Exchange Program In Second Year At Unl, Lynn Lutgen

Cornhusker Economics

The Agricultural Economics Department joined USDA in a Faculty Exchange Program (FEP) with the Ukraine and Russia in the spring of 1999. Each year four professors from the Ukraine and Russia arrive in Lincoln in August and leave the middle of December. While in Nebraska they take classes, travel, and develop class outlines and news articles that they will use when they return home. This year we have three professors visiting from the Ukraine and one from Russia. The following are their impressions of the U.S. and Nebraska, along with some thoughts on the Faculty Exchange Program.

'Earlibrite' Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims

Department of Plant Pathology: Faculty Publications

There is a need in west central Florida and other winter strawberry (Fragaria xananassa Duchesne) production areas for an early ripening cultivar to replace or be an alternative to 'Sweetcharlie' (Chandleretal., 1997a). 'Sweet Charlie' has benefitted the Florida strawberry industry through its relatively high production of fruit early in the season, when market prices are generally high. But the average fruit size is small, and the texture of its fruit is often soft, making shipment and shelf life of 'Sweet Charlie' problematic. 'Earlibrite' strawberry has produced high early-season (December through February) yields of large, flavorful fruit at the Univ. …

‘Strawberry Festival’ Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims

Department of Plant Pathology: Faculty Publications

Most of the strawberries (Fragaria xananassa Duchesne) produced in Florida are shipped fresh to locations throughout the eastern United States and Canada (Florida Agricultural Statistics [www.nass.usda.gov/ fl]). Therefore, Florida growers need cultivars that produce fruit that are attractive and flavorful, and maintain these qualities during and after long-distance shipment. 'Strawberry Festival' strawberry has produced commercially acceptable yields of firm, attractive, and flavorful fruit in trials at the Univ. of Florida's Gulf Coast Research and Education Center in Dover (GCREC-Dover) and in two commercial fields in west central Florida. It is recommended for trial in areas where strawberries are grown …

Enzymatic Nixtamalization: An Improved Corn Masa Flour Production Process, Deepak Sahai, David S. Jackson

Department of Food Science and Technology: Public Access Records

A major concern during commercial masa or instant masa flour production is the proper disposal of the excess waste water generated from the nixtamalization process. Nixtamalization causes partitioning of corn solids between nixtamal and waste water. It has been estimated that corn solids loss during nixtamalization varies between 5-14% depending on corn type & quality. Nejayote waste is highly alkaline, with high chemical and biological oxygen demands (BOD & COD) and is considered an environmental pollutant. A typical corn nixtamalization facility processing 200 US tons of corn every day, uses over 50 gallons of water per minute and generates nearly …

Planning And Design Considerations For Hybrid Poplar Timberbelts, Scott J. Josiah, Gary Kuhn

Agroforestry Notes (USDA-NAC)

The demand for wood products and wood fiber has led to the development of a production system based on fast growing trees known as Short Rotation Woody Crops (SRWCs). Traditionally, SRWCs are grown in large, intensively managed blocks, but the technology may also be used on agricultural lands in integrated applications such as timberbelts. Timberbelts are multiple row windbreaks that are planted with commercially valuable trees to produce wood products. Trees such as hybrid poplar (typically cottonwood and to a lesser extent aspen), hybrid willow, hybrid pine, paulownia, etc., are particularly suited for use in timberbelts because of their rapid …

From A Pasture To A Silvopasture System, James L. Robinson, Terry Clason

Agroforestry Notes (USDA-NAC)

There is potential to diversify a grazing operation and improve economic or environmental benefits on many acres through conversion of pasture to silvopasture. Silvopasture is the integration of trees with livestock grazing and forage operations. Research has demonstrated that, if managed properly, forage production can be maintained while producing high value timber.

De Sistemas Pastoriles A Silvopastoriles, James L. Robinson, Terry Clason

Agroforestry Notes (USDA-NAC)

Existe el potencial para diversificar la operación pastoril y mejorar los beneficios económicos y ambientales en muchas áreas a través de la conversión de pastoreo a silvopastoreo. Silvopastoreo es la integración de árboles y ganado junto con forraje. Estudios han demostrado que bajo una buena administración es posible la producción de pastos y de madera de alta calidad.

Phylogenetic Relationships Among Species Of Stilestrongylus Freitas, Lent And Almeida, 1937 (Trichostrongyloidea: Heligmonellidae: Nippostrongylinae), Parasites Of Myomorph Rodents (Rodentia: Muridae) In The Neotropics, Gerardo Perez-Ponce De Leon, Scott Lyell Gardner, Jorge Falcon-Ordaz

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The phylogenetic relationships of 14 species of Stilestrongylus were analyzed using the comparative morphology of 21 characters. We obtained 2 shortest trees of 50 steps, with a consistency index of 0.540 and 25 apomorphic character states. Ingroup monophyly was supported on these trees by 2 and 3 synapomorphies, respectively, and the ingroup was defined by the following characters: greater number of ventral ridges relative to the number of ridges dorsally, asymmetric bursa, and externodorsal rays differing in size. Sister-group relationships among Stilestrongylus and the other genera designated as outgroups are relatively consistent with those postulated by Durette-Desset’s in a classification …

Ecogeographic Aspects Of Greater Prairie-Chicken Leks In Southeastern Nebraska, Paul A. Johnsgard

Nebraska Bird Review

An analysis of the distribution of 104 Greater Prairie-chicken leks in Pawnee and Johnson counties indicates that the birds favor using those mile-square sections having no more than two dwellings per section, ones that are located at least two miles from the nearest town, and at least a half-mile from the nearest lek. Relationships with the nearest water were not clear, but most leks were located at least a half-mile from it, perhaps reflecting a general avoidance of heavy cover during the display season.

Influence Of Infected Cell Growth State On Bacteriophage Reactivation Levels, Dana R. Kadavy, Julie J. Shaffer, Susan E. Lott, Thomas A. Wolf, Cathy E. Bolton, William H. Gallimore, Eugene L. Martin, Kenneth W. Nickerson, Tyler A. Kokjohn

Papers in Microbiology

Reactivation of UV-C-inactivated Pseudomonas aeruginosa bacteriophages D3C3, F116, G101, and UNL-1 was quantified in host cells infected during the exponential phase, during the stationary phase, and after starvation (1 day, 1 and 5 weeks) under conditions designed to detect dark repair and photoreactivation. Our experiments revealed that while the photoreactivation capacity of stationary-phase or starved cells remained about the same as that of exponential-phase cells, in some cases their capacity to support dark repair of UV-inactivated bacteriophages increased over 10-fold. This enhanced reactivation capacity was correlated with the ca. 30- fold-greater UV-C resistance of P. aeruginosa host cells that were …

Characterization Of Transcripts Expressed From Human Herpesvirus 6a Strain Gs Immediate-Early Region B U16-U17 Open Reading Frames, Linda Flebbe-Rehwaldt, Charles Wood, Bala Chandran

Nebraska Center for Virology: Faculty Publications

Several gene fragments of human herpesvirus 6 (HHV-6) have been shown to activate the human immunodeficiency virus (HIV) type 1 long terminal repeat (LTR). An open reading frame (ORF) designated B701 (Y. Geng, B. Chandran, S. F. Josephs, and C. Wood, J. Virol. 66:1564–1570, 1992), found within a 22-kb HHV-6A strain GS [HHV-6A(GS)] genomic fragment and a 3.8-kb SalI subfragment, was shown to activate the HIV LTR. B701, also known as HHV-6 U16, is located in the immediate-early B (IE-B) region of the genome. The sequence of the 3.8-kb genomic fragment of HHV-6A(GS) is nearly identical to the published …

Variation At Tri- And Tetranucleotide Repeat Microsatellite Loci In The Fruit Bat Genus Cynopterus (Chiroptera: Pteropodidae), Jay F. Storz

Jay F. Storz Publications

There is considerable uncertainty surrounding the taxonomic relationship between Cynopterus sphinx and C. brachyotis, and the status of the many named forms within C. sphinx (Storz & Kunz 1999). Polymorphic microsatellite markers for cynopterine fruit bats would greatly aid efforts to elucidate species boundaries and genetic correlates of morphological variation within species. To assess levels of variation in C. sphinx and C. brachyotis, microsatellite genotypes were obtained for a total of 731 bats (620 C. sphinx and 111 C. brachyotis).

Role Of ΣB In Adaptation Of Listeria Monocytogenes To Growth At Low Temperature, Lynne A. Becker, Stefanie N. Evans, Robert W. Hutkins, Andrew K. Benson

Department of Food Science and Technology: Faculty Publications

The activity of σ^B in Listeria monocytogenes is stimulated by high osmolarity and is necessary for efficient uptake of osmoprotectants. Here we demonstrate that, during cold shock, σ^B contributes to adaptation in a growth phase-dependent manner and is necessary for efficient accumulation of betaine and carnitine as cryoprotectants.

Observations On Small Mammals Recovered From Owl Pellets From Nebraska, Jeffrey J. Huebschman, Hugh H. Genoways, Patricia W. Freeman, Joseph A. Gubanyi

University of Nebraska State Museum: Mammalogy Papers

Mammalian remains from owl pellet material collected in 24 Nebraska counties were examined. A total of 1262 individual mammals was identified from all owl pellet material and included 19 identifiable species and 21 total genera. The most commonly consumed prey by owls across the state were Microtus (41% of identifiable prey material), followed by Peromyscus (18%), and Reithrodontomys (11%). Significant locality information for the northern grasshopper mouse (Onychomys leucogaster), the southern bog lemming (Synaptomys cooperi), and the meadow vole (Microtus pennsylvanicus) are reported.

Tetrops Praeusta (L.) (Coleoptera: Cerambycidae), A Potential Pest?, Henry Howden, Anne Howden

Insecta Mundi

Thanks to Richard G. Dearborn we were able to examine the collection of beetles of the Maine Forest Service, Department of Conservation, Augusta. Our attention was directed to two small (4-6 mm) cerambycids by their collector, Kimberly Foss. The specimens are cylindrical, black bodied with tan, black tipped, setose elytra and tan legs. One specimen had been taken sitting on a maple leaf at Portland, Maine, and the other was collected by sweeping at Augusta, Maine. Subsequently an additional two specimens were collected in our Malaise trap on the Dearborn property 10 mi. S. Mt. Vernon, Maine.
