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 …

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) …

Geographic Differences In Host Acceptance And Suitability Of Two Cotesia Sesamiae Populations In Zimbabwe, P. Chinwada, W. A. Overholt, C. O. Omwega, J. M. Mueke

All Peer-Reviewed Publications

Three lepidopteran stemborers, Busseola fusca Fuller (Noctuidae), Sesamia calamistis Hampson (Noctuidae), and Chilo partellus (Swinhoe) (Crambidae), were evaluated for their acceptability for oviposition and suitability for development by two populations of the larval endoparasitoid Cotesia sesamiae (Cameron) (Hymenoptera: Braconidae) occurring in the highveld (>1200m) and lowveld (<600 m) regions of Zimbabwe. Mating studies were also conducted to determine reproductive compatibility between the populations. Both C. sesamiae populations preferred the noctuids to C. partellus for oviposition. possibly reflecting differences in evolutionary history. Although B. fusca was partially suitable for development of lowveld C. sesamiae, all three hosts were suitable for development of the highveld population. Crosses between highveld and lowveld C. sesamiae were compatible, and were generally not different from the intra-population crosses in developmental time, % adult emergence and sex ratio. However, broods were much larger when highveld males were used in the mating combinations. We conclude that although there is host overlap and probably a considerable degree of outbreeding between the two C. sesamiae populations, there are still significant genetic differences between them. Within Zimbabwe, it is unlikely that the deliberate introduction of either population outside its region of occurrence will give meaningful stemborer control. © 2003 Elsevier Science (USA).

Host Specificity Of Psyttalia Cosyrae (Hymenoptera: Braconidae) And The Effect Of Different Host Species On Parasitoid Fitness, Samira A. Mohamed, William A. Overholt, Robert A. Wharton, Slawomir A. Lux, Elameen M. Eltoum

All Peer-Reviewed Publications

Psyttalia cosyrae (Wilkinson) (Hymenoptera: Braconidae) is a synovigenic, koinobiont larval-pupal parasitoid of Ceratitis cosyra (Walker) (Diptera: Tephritidae), and possibly other tephritid fruit flies. Host acceptance and suitability of medfly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), mango fruit fly, Ceratitis cosyra, Natal fruit fly, Ceratitis rosa Karsch, Ceratitis fasciventris (Bezzi), Ceratitis anonae Graham, and melon fruit fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae), for oviposition and development of this parasitoid were investigated. The effect of different host species on traits widely used to assess parasitoid fitness was also evaluated. Psyttalia cosyrae accepted all host species tested, but acceptance varied. In no choice tests, …

An Arthropod Defensin Expressed By The Hemocytes Of The American Dog Tick, Dermacentor Variabilis (Acari: Ixodidae), Shane M. Ceraul, Daniel E. Sonenshine, Robert E. Ratzlaff, Wayne L. Hynes

Biological Sciences Faculty Publications

Both soluble and cell-mediated components are involved in the innate immune response of arthropods. Injection of Borrelia burgdorferi, the Lyme disease agent, results in the secretion of defensin into the hemolymph of the ixodid tick, Dermacentor variabilis. The presence of the peptide is observed as early as 15 min post-challenge and remains present through 18 h post-challenge. As observed in insects and soft ticks, the transcript for defensin is detected as early as 1 h post-challenge in D. variabilis. RT-PCR resulted in an amplicon of 624 bp with a 225 bp region that translates to a 74 …

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, …

Evidence For The Involvement Of A Tsetse Midgut Lectin-Trypsin Complex In Differentiation Of Bloodstream-Form Trypanosomes, L. U. Abubakar, G. Zimba, C. Wells, F. Mulaa, E. O. Osir

All Peer-Reviewed Publications

We have previously described a bloodmeal-induced molecule (lectin-trypsin complex) from the midgut of the tsetse fly, Glossina longipennis, with both lectin and trypsin activities (Osir et al., 1995). In this paper, we report on the isolation of a similar molecule from the midguts of Glossina fuscipes fuscipes and provide direct evidence for its involvement in the development of African trypanosomes. The molecule (native Mr ∼65,700) has two non-covalently linked subunits, Mr ∼28,800 and Mr ∼35,700. The native molecule was found to be capable of inducing differentiation of bloodstream-form trypanosomes into procyclic (midgut forms) in vitro. In the assays, specific antibodies …

High Seasonal Variation In Entomologic Inoculation Rates In Eritrea, A Semi-Arid Region Of Unstable Malaria In Africa, Josephat Shililu, Tewolde Ghebremeskel, Solomon Mengistu, Helen Fekadu, Mehari Zerom, Charles Mbogo, John Githure, Robert Novak, Eugene Brantly, John C. Beier

All Peer-Reviewed Publications

Entomologic studies were conducted in eight villages to investigate the patterns of malaria transmission in different ecologic zones in Eritrea. Mosquito collections were conducted for 24 months between September 1999 and January 2002. The biting rates of Anopheles arabiensis were highly seasonal, with activity concentrated in the wet season between June and October in the highlands and western lowlands, and between December and March in the coastal region. The biting rates in the western lowlands were twice as high as in the western escarpment and 20 times higher than in the coastal region. Sporozoite rates were not significantly different among …

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 …

Thrips Species Composition In Louisiana Cotton And Associated Management Strategies, Donald Ray Cook

LSU Doctoral Dissertations

The common species of thrips infesting cotton seedlings include flower thrips, Frankliniella tritici (Fitch); tobacco thrips, Frankliniella fusca (Hinds); western flower thrips, Frankliniella occidentalis (Pergande); onion thrips, Thrips tabaci (Lindeman); and soybean thrips, Neohydatothrips variabilis (Beach). In surveys of cotton seedlings at several locations in Louisiana, tobacco thrips was the most common species. The occurrence of flower thrips and soybean thrips was variable. Western flower thrips accounted for < 15% of adults collected at all locations, except two. The performance of acephate and imidacloprid applied as seed treatments and in-furrow, and aldicarb applied in-furrow was evaluated for thrips management across different production environments. Insecticide treatments reduced thrips densities and delayed development of thrips larval populations. The at-planting insecticides influenced thrips species composition in some instances. In studies to evaluate the effects of winter-spring vegetation type (native vegetation and wheat) on aldicarb efficacy, vegetation type did not influence thrips densities on cotton, with one exception. Aldicarb reduced thrips densities regardless of vegetation type. Vegetation type or insecticide treatments did not influence lint yield. Increasing aldicarb rates generally did not improve thrips control. Aldicarb rates currently recommended in conventional tillage systems should be adequate for systems that incorporate winter-spring vegetation as cover crops. Additional studies were conducted to further investigate the influence of thrips on crop maturity and yield. The addition of an at-planting insecticide improved lint yield in one of six tests. Thrips infestations did not affect crop maturity, and with few exceptions boll distribution and boll retention. The majority of these exceptions were associated with the test where the addition of an at-planting insecticide improved lint yield. Several soil applied at-planting insecticides were evaluated against tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), in a field caged infestation study. Acephate and imidacloprid provided little control of tarnished plant bugs. Thiamethoxam and aldicarb resulted in ≥ 50% tarnished plant bug mortality until 10 and 18 DAE, respectively. These are the first reports of western flower thrips infesting cotton seedlings in Louisiana. The addition of an at-planting insecticide provided control of thrips, but affects on crop maturity and yield were variable.

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 …

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 …

Assessment Of Grain Yield Losses In Pearl Millet Due To The Millet Stemborer, Coniesta Ignefusalis (Hampson), Aissetou Drame-Yaye, Ousmane Youm, Jonathan N. Ayertey

Department of Entomology: Faculty Publications

Studies were conducted at the ICRISAT Sahelian Centre, Niger, to assess damage and yield loss by the millet stemborer, Coniesta ignefusalis (Lepidoptera: Pyralidae) on Pennisetum glaucum (L.) R. Brown. Although 78% of stems were infested, late attack by the millet stemborer on millet plants resulted in bored stems yielding more than unbored ones. Artificial infestations with 5 and 10 larvae per plant at 2 weeks after plant emergence (WAE) resulted in 50 to 70% plants with deadhearts and 24 to 100% avoidable yield loss. At 4 weeks after plant emergence, infestations with 5 larvae and 10 larvae per plant resulted …

Life Span Extension Of Drosophila Melanogaster: Genetic And Population Studies, Lawrence G. Harshman

Lawrence G. Harshman Publications

During the past two decades, genetic studies of model organisms have been the most important tool underlying advances in understanding the biological basis of aging and longevity. Drosophila melanogaster, the geneticist's "fruit fly," is a model organism because it has been the focus of genetic studies for more than 90 years. This review argues that studies on D. melanogaster will make an especially important contribution to the field of aging and longevity at the intersection of research on genetics, complex traits, and fly populations.

Five approaches have been used to study the genetics of longevity of D. melanogaster: …

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 …
