Compositions And Methods For Synergistic Manipulation Of Plant And Insect Defenses, Graham Moores, Georgina Bingham

Department of Entomology: Faculty Publications

This invention relates to the control of plant pests, such as aphid and whitefly by treating plants with a compound which inhibits the plant pests ability to overcome plant defense responses, such as piperonyl butoxide or propyl gallate, in combination with a compound which activates plant defense responses, such as cis-Jasmone or beta-aminobutyric acid.

Investigations On Rangeland Grasshoppers: Ecoregion Level Distribution, Identification, Feeding Performance, And Vegetation Clipping, Muhammad Ullah

Department of Entomology: Dissertations, Theses, and Student Research

Short-horned grasshoppers (Orthoptera: Acrididae) were studied in the field as well as in laboratory for their distribution, identification, preferred food plants and feeding damage. These grasshoppers are important potential pests of rangelands where they compete for forage with cattle. Examination of the 20 most common grasshoppers by levels 3 and 4 of Nebraska ecoregions revealed specific habitat use and may be helpful in predicting hotspots. The relative abundance of all species analyzed showed at least some significant differences at ecoregion level 4 and two species showed single ecoregion that differed from all others at level 3.

Comparison Of Three Collection Techniques For Capture Of Coleoptera, With An Emphasis On Saproxylic Species, In Great Smoky Mountains National Park, Usa, Michael L. Ferro, Matthew L. Gimmel, Kyle E. Harms, Christopher E. Carlton

Insecta Mundi

Collection methods and/or habitats sampled influence how many and which species are captured during entomological surveys. Here we compare Coleoptera catches among three survey activities, each using a single collection method, at the same study sites in Great Smoky Mountains National Park, USA. Activities included: short-term flight intercept trapping (FITs); sifting/Berlese funneling of leaf litter and extremely decayed downed coarse woody debris; and using emergence chambers containing coarse woody debris of various decay classes. In total, 2472 adult beetle specimens, representing 217 lowest identifiable taxa within 164 genera and 42 families, were collected during the FIT survey. Each survey activity …

Investigating The Tolerance Response Of Early Vegetative Stage Soybeans To Aphis Glycines Matsumura, Lia Da Silva Marchi

Department of Entomology: Dissertations, Theses, and Student Research

The objectives of this research were to evaluate the impact of soybean aphid (Aphis glycines Matsumura) feeding on the yield response of V1, V3, and R1 KS4202 soybean plants and examine the effect of soybean aphid feeding on peroxidase activity in V1 and V3 KS4202 plants. KS4202 plants infested during the early vegetative stages (VC, VE and V1) were identified as highly susceptible based upon plant damage and stunting of the plants. In contrast, V3, V4, and V5 stage KS4202 soybeans were classified as moderately resistant. In the yield response study, V1, V3 and R1 plants had aphid numbers …

Cerambycidae In The Hawk Rise Sanctuary, Linden, Nj, Tiffany R. Mauro

Department of Entomology: Distance Master of Science Projects

The family Cerambycidae is a diverse group. These wood borers greatly impact the flora and fauna of the habitat in which they reside. One of the most destructive invasive cerambycids is the Asian Longhorned Beetle (ALB) Anoplophora glabripennis. It has devastated both the urban and forested landscapes in New York, Illinois, New Jersey, Massachusetts, and Ohio. It threatens the maple syrup industry, logging, and tourism tied to the fall foliage in New England. In New Jersey thousands of trees were removed and chemically treated due to the ALB infestation. The communities where this infestation occurred were greatly impacted as …

A Survey Of Spiders (Arachnida: Araneae) Of Prince Of Wales Island, Alaska; Combining Morphological And Dna Barcode Identification Techniques, Jozef Slowik, Gergin A. Blagoev

Insecta Mundi

Surveys during the summer of 2004 and August 2009 on Prince of Wales Island, Alaska, USA resulted in collection of 1064 adult spiders representing 84 species. Barcoding of spiders collected in 2009 resulted in DNA barcode data for 212 specimens representing 63 species. DNA barcode data were then used to facilitate the identification of otherwise unidentifiable juvenile and female specimens as well as to investigate phylogenetically four lineages with large branch lengths between specimens. Using morphological and DNA barcode identifications provided a more complete list of identified specimens than was possible using morphological data alone.

Rediscovery And Status Of Cylindera (S. Str.) Lunalonga (Schaupp, 1884) (Coleoptera: Carabidae: Cicindelinae) In The San Joaquin Valley Of California With A Comparison To A Sierra Nevada Population, Mike Kippenhan, C. Barry Knisley, R. Dennis Haines

Insecta Mundi

Surveys for adult Cylindera (s. str.) lunalonga (Schaupp) (Coleoptera: Carabidae: Cicindelinae) were conducted between 2001 and 2011 at over 80 sites throughout the species’ historic range in the San Joaquin Valley and Sierra Nevada Mountains of California. Previously considered extirpated from the Valley, these surveys resulted in finding adults at 18 sites, several with large populations (>50 individuals). As suggested by historic records, our studies confirmed that the Valley populations of Cy. lunalonga occur in what were historically wetland sites, but are now lowland agricultural croplands. Adults were always associated with wet, muddy soil within and along the edges …

Genetic Characterization Of North American Populations Of The Wheat Curl Mite And Dry Bulb Mite, Gary L. Hein, Roy French, Benjawan Siriwetwiwat, James W. Amrine

Department of Entomology: Faculty Publications

The wheat curl mite, Aceria tosichella Keifer, transmits at least three harmful viruses, wheat streak mosaic virus (WSMV), high plains virus (HPV), and Triticum mosaic virus (TriMV) to wheat (Triticum aestivum L.) throughout the Great Plains. This virus complex is considered to be the most serious disease of winter wheat in the western Great Plains. One component of managing this disease has been developing mite resistance in wheat; however, identification of mite biotypes has complicated deployment and stability of resistance. This biotypic variability in mites and differential virus transmission by different mite populations underscores the need to better understand …

New Distributional Records Of Great Plains Pseudo Scorpions (Arachnida: Pseudoscorpiones), Paul O. Cooney, James A. Kalisch

Great Plains Research: A Journal of Natural and Social Sciences

Pseudoscorpions are tiny, oval, brown, flattened arachnids that possess large "pinchers" in front of the body for capturing smaller prey. They generally live in forested habitats in soil litter or beneath loose bark. It has been presumed that pseudoscorpions are scarce in the Great Plains, except for along rivers, due to harsh climatic conditions. However, new records of pseudo scorpions from the Great Plains were derived from identification of specimens obtained from university and college collections, and from specimens collected by the first author. Records provided new revelations about distributions of not only the more commonly known pseudoscorpion species but …

Evolutionary History Of Assassin Bugs (Insecta: Hemiptera: Reduviidae): Insights From Divergence Dating And Ancestral State Reconstruction, Wei Song Hwang, Christiane Weirauch

Harold W. Manter Laboratory: Library Materials

Assassin bugs are one of the most successful clades of predatory animals based on their species numbers (~ 6,800 spp.) and wide distribution in terrestrial ecosystems. Various novel prey capture strategies and remarkable prey specializations contribute to their appeal as a model to study evolutionary pathways involved in predation. Here, we reconstruct the most comprehensive reduviid phylogeny (178 taxa, 18 subfamilies) to date based on molecular data (5 markers). This phylogeny tests current hypotheses on reduviid relationships emphasizing the polyphyletic Reduviinae and the blood-feeding, diseasevectoring Triatominae, and allows us, for the first time in assassin bugs, to reconstruct ancestral states …

First Recorded Introduction Of The Milliped Order Stemmiulida (Eugnatha: Nematophora): Potential Establishment In Florida, Usa, And New Records From Mexico; Northward Range Extension Into Southern Tamaulipas, Rowland M. Shelley, G. B. Edwards, Arthur E. Bogan

Insecta Mundi

Based on two “uni-ocellate” females, the world’s first introductions of the milliped order Stemmiulida are recorded from Florida, United States (US). One individual was collected in 1976 in Gainesville, Alachua County (Co.)., in northcentral peninsular Florida, and the other was taken in 1991 some 408 km (255 mi) to the south-southeast in Pompano Beach, Broward Co. The absence of further individuals and additional samples suggests that the introductions did not result in viable populations, and stemmiulidans are not presently established in the state; the Gainesville site was reinvestigated in 2012 without finding additional specimens. New records from Mexico include the …

Factors Affecting The Distribution And Survival Of Endangered American Burying Beetles, Nicrophorus Americanus Olivier, Jessica Jurzenski

Department of Entomology: Dissertations, Theses, and Student Research

The disappearance of the federally endangered American burying beetle (Nicrophorus americanus Olivier) over most of its range is poorly understood, which is why the identification and evaluation of conservation measures is important. The presence and distribution of all carrion beetles in Nebraska was first reported to help understand where American burying beetles (ABBs) occur to aid in creating a habitat suitability model for the Sandhills ecoregion and to locate suitable experiment areas. There are 18 Nebraska counties with records of ABB presence in the last 15 years. The final habitat suitability model performed well with an AUC value above …

High-Throughput Transcriptome Sequencing For Snp And Gene Discovery In A Moth, Nicholas J. Miller, Jing Sun, Thomas W. Sappington

Department of Entomology: Faculty Publications

The western bean cutworm, Striacosta albicosta (Smith) (Leptidoptera: Noctuidae) is a pest of corn (Zea mays L.) and dry beans that underwent a dramatic range expansion in North America during the first decade of the 21st century. Research into the population genetics of this species has been hindered by a lack of genetic markers. The transcriptome of adult male S. albicosta was partially sequenced using Illumina sequencing-by-synthesis. Assembly of the sequence reads yielded 16,847 transcript sequences, of which 6,631 could be assigned a putative function. A search for single nucleotide polymorphisms (SNPs) identified 2,487 candidate SNPs distributed among 1,265 …
