Inheritance Of Methyl-Parathion Resistance In Nebraska Western Corn Rootworm Populations (Coleoptera: Chrysomelidae), Srivinas Parimi, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

Field populations of western corn rootworm, Diabrotica virgifera virgifera LeConte, were collected from three different sites (York Co., Phelps Co., and Saunders Co.) in Nebraska during 1996.Adult bioassays of these three populations were conducted with different concentrations of methyl-parathion and at a diagnostic concentration (1.0 μg/ml) to determine resistance levels among these populations. Self and reciprocal crosses were made between the two resistant and one susceptible laboratory-reared populations. Dose-responses and dominance ratios calculated for the four reciprocal crosses indicated that resistance was incompletely dominant in both strains, although in one of the strains there was an indication of sex linkage. …

Comparative Analysis Of Microsatellite Loci In Four Fruit Fly Species Of The Genus Ceratitis (Diptera: Tephritidae), F. N. Baliraine, M. Bonizzoni, E. O. Osir, S. A. Lux, F. J. Mulaa, L. Zheng, L. M. Gomulski, G. Gasperi, A. R. Malacrida

All Peer-Reviewed Publications

The possibility to cross-species amplify microsatellites in fruit flies of the genus Ceratitis was tested with the polymerase chain reaction (PCR) by analysing 23 Ceratitis capitata (Wiedemann) microsatellite markers on the genomic DNA of three other economically important, congeneric species: C. rosa (Karsch), C. fasciventris (Bezzi) and C. cosyra (Walker). Twenty-two primer pairs produced amplification products in at least one of the three species tested. The majority of the products were similar, if not identical in size to those expected in C. capitata. The structures of the repeat motifs and their flanking sequences were examined for a total of 79 …

Enrichment Of A Single Clone From A High Diversity Library Of Phage-Displayed Antibodies By Panning With Anopheles Gambiae (Diptera: Culicidae) Midgut Homogenate, G. F. Killeen, B. D. Foy, R. H. Frohn, D. Impoinvil, A. Williams, J. C. Beier

All Peer-Reviewed Publications

A high diversity library of recombinant human antibodies was selected on complex antigen mixtures from midguts of female Anopheles gambiae Giles. The library of phage-displayed single chain variable region fragment constructs, derived from β-lymphocyte mRNA of naïve human donors, was repeatedly selected and reamplified on the insoluble fraction of midgut homogenates. Five rounds of panning yielded only one midgut-specific clone, which predominated the resulting antibody panel. In A. gambiae, the epitope was found throughout the tissues of females but was absent from the midgut of males. The cognate antigen proved to be detergent soluble but very sensitive to denaturation and …

New Host And Elevation Records For Moneilema Appressum Leconte (Coleoptera: Cerambycidae: Lamiinae), Steven Lingafelter

USDA Systematic Entomology Laboratory

An isolated population of Moneilema appressum LeConte was discovered above Long Park in the Chiricahua Mountains of southeastern Arizona (31°52’44”N, 109°17’12”W) during July 2001. Specimens of this flightless lamiine cerambycid were observed hiding and walking in the junctures of Echinocereus coccineus Engelmann (Cactaceae) at 2,760 m (9,055 feet). These data represent new host plant and elevation records for this species.

Early Childhood Thematic Unit: A 32-Week Curricular Resource: Fairy Tales - Insects - Dinosaurs, Institute For The Development Of Gifted Education, Ricks Center For Gifted Children, University Of Denver

Ricks Curriculum Units Series

An integrated curriculum is an instructional approach that connects the disciplines to an underlying theme or topic. Immersing students in an integrated-thematic unit provides the backdrop for experiences to occur across the disciplines. Shaping coursework around integrated themes is especially appropriate for gifted students, however using an integrated-thematic curriculum is appropriate for all learners as it develops students' abilities to make connections, to solve problems by looking at multiple perspectives, and to integrate information from different fields of experience. An integrated-thematic curriculum permits students to be active participants in their own learning as they design their own explorations and take …

Entomology Papers from Other Sources

The semiochemical cues used by geographically isolated strains of the parasitoid, Telenomus podisi (Ashmed), to find eggs of the stink bug Euschistus heros were investigated.

Effects Of Sucrose Concentrations And Fly Age On Feeding Responses And Survival Of Female And Male Western Cherry Fruit Flies, Rhagoletis Indifferens, Wee L. Lee

Entomology Papers from Other Sources

The effects of single meals of different sucrose concentrations on feeding responses and survival of 8–24-h-old, 1–2-, 10–12- and 31–36-day-old female and male western cherry fruit flies, Rhagoletis indifferens Curran, were determined. Feeding time and food consumption response patterns in both sexes within age groups were curvilinear. Feeding times increased as sucrose concentrations increased, and were longest when the sucrose concentration was 100% (dry). Consumption of dilute wet sucrose was low, whereas consumption of concentrated wet sucrose was high. However, consumption of dry, 100%sucrose was also low. One to 2-day-old flies of both sexes that had not previously fed consumed …

Dragonflies (Odonata) Of The Ouachita National Forest, George L. Harp, Phoebe A. Harp

Journal of the Arkansas Academy of Science

The Ouachita National Forest (ONF) was established in 1907 and encompasses 1.8 million acres (728,450 ha) in Arkansas and Oklahoma, almost entirely within the Ouachita Mountains Natural Division. The adult dragonfly species richness, seasonal and spatial distribution, and relative abundance were surveyed during 2002. Fifty-four collections were made at 43 sites during 10-19 May (20 collections), 10-22 July (19 collections) and 9-17 September (15 collections). Literature records were searched, as well as records from pertinent museums and individuals. Eighty-three species are reported here for the ONF, 77 of which were collected during 2002. Nehallenia integricollis newly reported for Arkansas, as …

Investigation Of Matrilineal Relationships Via Mitochondrial Dna In The Southeastern Yellowjacket (Vespula Squamosa), Anthony Deets

Masters Theses

The question of whether and how apparently "altruistic" behaviors can evolve in social animals has received an enormous amount of attention from evolutionary biologists and has been termed "the central theoretical problem of sociobiology". Thus, recent interest is eusocial species with coexisting multiple queens stems from the realization that the genetic relatedness of individuals in such colonies presents additional theoretical challenges beyond those addressed by the Hamiltonian model of kin selection and lengthens the potential list of reproductive conflicts of interest.

The Southeastern Yellowjacket (Vespula squamosa) exhibits two social forms sympatrically in the southern parts of its range. These two …

Imported Longhorned Weevil (Coleoptera: Curculionidae) Injury To Soybean: Physiological Response And Injury Guild-Level Economic Injury Levels, Thomas E. Hunt, Leon G. Higley, Fikru J. Haile

Department of Entomology: Faculty Publications

The imported longhorned weevil, Calomycterus setarius Roelofs, is an occasional pest of soybean, Glycine max (L.), and can cause substantial defoliation of seedling soybean when the weevil is present in large numbers. Because weevil populations can reach high levels, the potential exists for significant seedling injury, so economic injury levels (EILs) are needed for imported longhorned weevil on seedling soybean. Because the bean leaf beetle, Cerotoma trifurcata (Forster), also is present on seedling soybean, injury by this insect should be included in EIL calculations. This study was conducted to (1) determine daily soybean consumption rates of imported longhorned weevil; (2) …

A Monographic Revision Of The Genus Platycoelia Dejean (Coleoptera: Scarabaeidae: Rutelinae: Anoplognathini), Andrew B. T. Smith

Bulletin of the University of Nebraska State Museum (1924–2023)

This paper presents a taxonomic revision of the genus Platycoelia Dejean (Coleoptera: Scarabaeidae: Rutelinae: Anoplognathini: Platycoeliina). Phylogenetic analyses of all species in the genus were conducted and the biogeography of the genus is discussed. The phylogenetic analysis supports the monophyly of Platycoelia and divides the genus into four major clades. Based on the cladistic analysis, the generic names Callichloris Burmeister, Leucopelaea Bates, and Epicallichloris Gutiérrez are considered synonyms of Platycoelia. Character states supporting monophyletic clades are discussed. Descriptions and keys to all taxa are included.

The genus Platycoelia was revised and now includes 62 species, 19 of which are described …

Effects Of Mid-Season Avermectin Treatments Of Cattle On Pyrethroid Resistance In Three Populations Of Horn Flies, Haematobia Irritans Irritans (L.) (Diptera: Muscidae), Glenn R. Oremus

LSU Master's Theses

The effects of mid-season avermectin treatments on pyrethroid-resistant horn fly populations were examined between 1999-2002 at three separate Louisiana State University Agricultural Center research stations; Red River Research Station (Bossier City, LA), Macon Ridge Research Station (Winnsboro, LA) and St. Joseph (St. Joseph, LA). The cattle were treated with pyrethroid ear tags in all years at all farms, and each farm received a mid-season avermectin treatment in one year. With consecutive yearly use of pyrethroids the number of weeks of control decreased for all farms. The number of weeks of control rebounded at Red River from 2 to 13 weeks …

Nuclear Ribosomal Its Region Sequences For Differentiation Of Rubus Genotypes, Eric T. Stafne, John R. Clark, Allen L. Szalanski

Journal of the Arkansas Academy of Science

Previous molecular investigations into Rubus species diversity have yielded significant knowledge about species relatedness. However, little work has been focused at the cultivar level. Random amplified polymorphic DNA(RAPD)-PCR studies have successfully differentiated closely related cultivars. The ability to definitively distinguish blackberry and red raspberry cultivars based on other molecular methods could prove useful in many aspects of breeding and proprietary protection. In this study, the nuclear ribosomal DNA internal transcribed spacer regions (ITS) of six Rubus cultivars were sequenced. DNA sequencing revealed little genetic variation among blackberry cultivars, but revealed distinctions between blackberry and red raspberry cultivars. Analysis by maximum-parsimony …

Inhibitory Properties Of Microplitis Croceipes Teratocyte Secretory Products And The Recombinant Protein Tsp14 On Protein Synthesis, Francis Anthony Diluna

University of Kentucky Master's Theses

Microplitis croceipes is a solitary endoparasitic wasp that oviposits in the hemocoel of Heleothis virescens larvae. Upon parasitization, the host larvaes physiology is altered; resulting in a compromised immune system and a decrease in the production of some vital proteins resulting in a terminal post-wandering prepupal state. Teratocytes, cells derived from the extraembryonic serosa of the parasitic wasp, mimic symptoms of parasitization when injected into host larvae, independent of other factors like polydnavirus and venom. Some of the inhibition of protein synthesis can be attributed to proteins secreted by the teratocytes (teratocyte secretory proteins or TSP). A fraction of TSP …

Chemical Composition Of Some Components Of The Arrestment Pheromone Of The Black-Legged Tick, Ixodes Scapularis (Acari : Ixodidae) And Their Use In Tick Control, Daniel E. Sonenshine, Trevor Adams, Sandra A. Allan, John Mclaughlin, Francis X. Webster

Biological Sciences Faculty Publications

Chemical analysis (high-performance liquid chromatography) and bioassay demonstrated the presence of compounds that seem to be components of the Ixodes scapularis arrestment pheromone. Only two purines, guanine and xanthine, were found in acidified saline extracts made from cast skins after molting of fed nymphs, fed larvae, and fecal/excretory exudates deposited by unfed adults on substrates in their environment. The ratio of guanine to xanthine was 10.6:1 in an extract from the nymphal skins versus 0.95:1 in an extract from the larval skins. Guanine, xanthine, and traces of a third purine, tentatively identified as 8-azaguanine, were found in extracts made from …

Increase In Biomass And Soldier Production For Coptotermes Formosanus (Shiraki) Workers Maintained In The Laboratory For Up To Nine Months, Deborah Waller

Biological Sciences Faculty Publications

The factors that influence rates of soldier production in subterranean termites are poorly understood. In the present study, foraging groups of Coptotermes formosanus Shiraki were collected from baldcypress trees in Lake Charles, Lousiana, in November 1985, and February, April/May and August 1986. Termites were maintained in the laboratory for nine months, seven months, four/five months and zero months, respectively, and then examined for survivorship, termite biomass and soldier production after incubation for an additional five weeks at 30° C. Within collection periods, there was no association between survivorship and soldier production or between mean dry biomass and soldier production. However, …

The Probabilistic Economic Injury Level: Incorporating Uncertainty Into Pest Management Decision-Making, Robert K. D. Peterson, Thomas E. Hunt

Department of Entomology: Faculty Publications

Despite the recognition that the economic injury level (EIL) is determined by dynamic biological and economic parameters, which can be highly variable and uncertain, there has been little effort to quantify uncertainty and to use estimates of uncertainty in the determination of EILs. In this paper, we define the probabilistic EIL (PEIL) and develop PEILs for two insect pest scenarios: alfalfa weevil larvae, Hypera postica (Gyllenhal), on early bud-stage alfalfa, and bean leaf beetle adults, Cerotoma trifurcata (Forster), on V1-stage soybean. The PEIL is an EIL that reflects its probability of occurrence. The probability of occurrence is determined by incorporating …
