Candidate Sex Pheromones Of The New World Screwworm Cochliomyia Hominivorax, D.A. Carlson, Dennis Berkebile, S.R. Skoda, K. Mori, S. Mihok Mar 2007

Candidate Sex Pheromones Of The New World Screwworm Cochliomyia Hominivorax, D.A. Carlson, Dennis Berkebile, S.R. Skoda, K. Mori, S. Mihok

Department of Entomology: Faculty Publications

Five novel homologous acetate derivatives of long-chain secondary alcohols and a related ketone were tested for their efficacy as contact mating stimulants for Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae). Full copulatory behaviour at a high percentage was found in tests with racemic 6-acetoxy-19-methylnonacosane at 2.5 – 20 μg using fertile males from three strains. Males of two strains responded nearly as well to 7-acetoxy-15-methylnonacosane, but an older strain first colonized in 1992 did not respond to this compound. Few or no copulatory responses were obtained to the other secondary alcohol acetates and a related ketone. These two acetate derivatives are the …


Bothynus Hope, 1837 (Insecta, Coleoptera, Scarabaeidae): Proposed Conservation Of Usage By Designation Of Scarabaeus Ascanius Kirby, 1819 As The Type Species, Brett C. Ratcliffe, Andrew B. T. Smith Mar 2007

Bothynus Hope, 1837 (Insecta, Coleoptera, Scarabaeidae): Proposed Conservation Of Usage By Designation Of Scarabaeus Ascanius Kirby, 1819 As The Type Species, Brett C. Ratcliffe, Andrew B. T. Smith

University of Nebraska State Museum: Entomology Papers

The purpose of this application, under Article 70.3.2 of the Code, is to conserve the current usage of the generic name Bothynus Hope, 1837 for well-known scarab beetles of the family SCARABAEIDAE (subfamily DYNASTINAE) by designation of Scarabaeus ascanius Kirby, 1819 as the type species. The type species of Bothynus is at present Geotrupes cuniculus Fabricius, 1801, based on a misidentification. It has long been recognized that the species involved in Hope's misidentification of G. cuniculus is indeterminable. It is proposed that Scarabaeus ascanius Kirby, 18 19 is designated as the type species.


Maggot Development During Morgue Storage And Its Effect On Estimating The Post-Mortem Interval, Timothy Huntington, Leon G. Higley, Frederick P. Baxendale Mar 2007

Maggot Development During Morgue Storage And Its Effect On Estimating The Post-Mortem Interval, Timothy Huntington, Leon G. Higley, Frederick P. Baxendale

Department of Entomology: Faculty Publications

When insect evidence is obtained during autopsy, forensic entomologists make decisions regarding the effects of low-temperature (−1°C to 4°C) storage of the body and associated insects when estimating the post-mortem interval (PMI). To determine the effects of storage in a morgue cooler on the temperature of maggot masses, temperatures inside and outside of body bags containing a human cadaver and porcine cadavers (seven replicates) were measured during storage. Temperatures remained significantly higher (p < 0.05) inside of the body bags relative to the cooler, and remained at levels sufficient for maggot feeding and development. If the assumption that no insect development takes place during preautopsy refrigeration is made, potential error rates in PMI estimation of 8.6–12.8% occur. The potential for blow fly larvae to undergo significant development while being stored in the morgue is a possibility that forensic entomologists should consider during an investigation involving samples collected from autopsy. Case and experimental evidence also demonstrate that substantial tissue loss can occur from maggot feeding during morgue storage.

Interspecific And Intraspecific Differences In Foraging Preferences Of Container-Dwelling Mosquitoes, Kesavaraju Banugopan, Donald A. Yee, Steven A. Juliano Mar 2007

Interspecific And Intraspecific Differences In Foraging Preferences Of Container-Dwelling Mosquitoes, Kesavaraju Banugopan, Donald A. Yee, Steven A. Juliano

Faculty Publications – Biological Sciences

Feeding preferences of larval container-dwelling mosquitoes are not well understood. Primary production is often absent in container systems and external inputs of animal and plant detritus supply the energy base of container food webs by supporting microorganism prey for mosquitoes. We quantified the feeding preferences of Aedes albopictus (Skuse), a non-native invasive mosquito, and Ochlerotahts triseriatus (Say), a native mosquito, when given a choice of animal and plant detritus. We tested for interpopulational (Illinois versus Florida) differences in feeding preferences, and quantified each species' performance on these two detritus types. When given a choice, both species spent significantly more time …

All Peer-Reviewed Publications

The performance of the Bombyx mori Linnaeus bivoltine hybrid, Shaanshi BV-333, was evaluated on six mulberry cultivars of Morus spp. based on economic characters in rearing and mulberry leaf quality. The growth rate and morphological characteristics for all the cultivars were studied using several parameters. Specific characters such as disease resistance, survival percentage, cocoon weight, cocoon shell weight and single cocoon filament length were recorded during the rearing of silkworm larvae. Tested cultivars significantly differed in all parameters. Cultivars Kanva-2/M5, Thailand, Thika and S-36 exhibited superiority in rearing performance over other tested cultivars. Silkworms fed with cv. Thailand had the …


Ips Pini (Curculionidae: Scolytinae) Is A Vector Of The Fungal Pathogen, Sphaeropsis Sapinea (Coelomycetes), To Austrian Pines, Pinus Nigra (Pinaceae), Justin G.A. Whitehall, Jeffery S. Lehman, Pierluigi Bonello Feb 2007

Ips Pini (Curculionidae: Scolytinae) Is A Vector Of The Fungal Pathogen, Sphaeropsis Sapinea (Coelomycetes), To Austrian Pines, Pinus Nigra (Pinaceae), Justin G.A. Whitehall, Jeffery S. Lehman, Pierluigi Bonello

Biology and Earth Science Faculty Scholarship

Sphaeropsis sapinea (Fr.:Fr.) Dyko and Sutton, is among the most common and widely distributed pathogens of conifers worldwide. S. sapinea is disseminated over short distances by rain splash and moist wind, but significant knowledge gaps regarding long-range dispersal remain. Our objective was to determine whether or not the pine engraver beetle, Ips pini Say, is a vector of the pathogen onto Austrian pines (Pinus nigra Arnold). In 2004 and 2005, individuals of I. pini were collected with pheromone traps at two locations in central Ohio (197 and 1,017 individuals for 2004 and 2005, respectively) and screened for the presence of …


Enhancing Nest Sites For Native Bee Crop Pollinators, Mace Vaughan, Scott Hoffamn Black Feb 2007

Enhancing Nest Sites For Native Bee Crop Pollinators, Mace Vaughan, Scott Hoffamn Black

Agroforestry Notes (USDA-NAC)

The European honey bee receives most of the credit for crop pollination, but the number of managed honey bee hives is half of what it was in the 1950s; and this number continues to decline primarily because of honey bee pests and diseases. Native bees, however, contribute significantly to crop pollination and, on farms with sufficient natural habitat located nearby, may even provide all of the required pollination for some crops. In order to support the native bee community, it is essential to provide nesting sites in addition to floral resources. Unfortunately, intensively managed farm landscapes often lack the untilled …

Preliminary Notes On Tachinidae Reared From Lepidoptera In The Ecuadorian Andes, John O. Stireman Iii Feb 2007

Preliminary Notes On Tachinidae Reared From Lepidoptera In The Ecuadorian Andes, John O. Stireman Iii

Biological Sciences Faculty Publications

Current estimates of the species richness of Tachinidae among geographical provinces suggest that the Neotropical Region harbors the largest number of species and represents a geographic epicenter of tachinid diversification (O’Hara 2006). The Neotropics boasts an impressive fauna consisting of 2864 described species belonging to 822 genera at the time of the Neotropical catalog (Guimarães 1971), making it almost twice as species rich as any other geographic realm (O’Hara 2006; Stireman et al. 2006). This diversity is most apparent at middle elevations (1000– 2000m) along the mountain chains of tropical Central and South America, where tachinids are an abundant and …

Influence Of Buffalograss Management Practices On Western Chinch Bug And Its Beneficial Arthropods, Jeffrey Carstens, Tiffany Heng-Moss, Frederick P. Baxendale, Roch E. Gaussoin, Kevin Frank, Linda J. Young

Department of Entomology: Faculty Publications

A 2-yr study was conducted to document the influence of selected buffalograss, Buchloe dactyloides (Nuttall) Engelmann, management practices (three mowing heights and five nitrogen levels) on the seasonal abundance of the western chinch bug, Blissus occiduus Barber (Heteroptera: Lygaeidae), and its beneficial arthropods. Vacuum, pitfall, and sticky traps samples were collected every 14 d from the middle of May through October from western chinch bug-resistant (‘Prestige’) and -susceptible (‘378’) buffalograss management plots. In total, 27,374 and 108,908 western chinch bugs were collected in vacuum and pitfall traps, respectively. More than 78% of all western chinch bugs were collected from the …


Are Hawkmoths The Mysterious Pollinators Of The Jamestown Lily?, W. John Hayden Feb 2007

Are Hawkmoths The Mysterious Pollinators Of The Jamestown Lily?, W. John Hayden

Biology Faculty Publications

“Hawkmoth flowers are easy to predict but difficult to document,” noted botanist Verne Grant in his comprehensive review of hawkmoth pollination systems in North America (Botanical Gazette 144: 439-449. 1983). Grant included Jamestown (atamasco) lilies (among other zephyr lily species) as examples of plants that are probably hawkmoth- pollinated, but for which the actual pollination mechanism remains undocumented.

All Peer-Reviewed Publications

Surveys for predators of the tomato red spider mite Tetranychus evansi Baker & Pritchard on solanaceous plants were carried out in north-eastern and south-eastern Brazil to determine prospective species for the control of the pest in Africa. Surveys were carried out in areas identified as climatically similar to regions in Africa where T. evansi has been reported as a pest and where prospective natural enemies may be introduced. A total of 56,445 mites and insects were found in 330 samples collected from 20 different species of solanaceous plants. Tetranychus evansi was found in only three samples, on Solanum americanum Mill. …

Disproportionate Relative Importance Of A Terrestrial Beetle Family (Coleoptera: Scarabaeidae) As A Prey Source For Central Appalachian Brook Trout, Ryan M. Utz, Brett C. Ratcliffe, Brett T. Moore, Kyle J. Hartman Jan 2007

Disproportionate Relative Importance Of A Terrestrial Beetle Family (Coleoptera: Scarabaeidae) As A Prey Source For Central Appalachian Brook Trout, Ryan M. Utz, Brett C. Ratcliffe, Brett T. Moore, Kyle J. Hartman

University of Nebraska State Museum: Entomology Papers

Brook trout Salvelinus fontinalis and other salmonids in Appalachia typically inhabit headwater watersheds, where food resources may limit growth. We monitored the feeding trends of a brook trout population in central Appalachia over the course of 2 years to determine variation in feeding intensity and important prey items. One terrestrial beetle family, Scarabaeidae, provided a disproportionate amount of energy during the only time of year when brook trout were feeding substantially above maintenance ration. Scarab beetles contributed 39.6% of all energy consumed during May and June of both years, though the number of fish with one or more scarabaeids present …


Population Dynamics Of Soybean Aphid And Biotic Mortality At The Edge Of Its Range, Tierney R. Brosius, Leon G. Higley, Thomas E. Hunt Jan 2007

Population Dynamics Of Soybean Aphid And Biotic Mortality At The Edge Of Its Range, Tierney R. Brosius, Leon G. Higley, Thomas E. Hunt

Department of Entomology: Faculty Publications

The soybean aphid, Aphis glycines Matsumura, was introduced to north central North America from Asia in 2000, and it has become a major pest of soybean, Glycine max (L.) Merr. Understanding how natural enemies impact aphid populations in the field is an important component in developing a comprehensive management plan. We examined the impact of naturally occurring predators in the Þeld by using exclusion cages during July-August 2004 and 2005. Field cages of different mesh diameters were used to exclude different sizes of natural enemies from aphid-infested plots. Plots were surveyed twice weekly for A. glycines and natural enemies. Densities …


Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar Jan 2007

Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar

School of Natural Resources: Faculty Publications

Predicting the spatial foci of zoonotic diseases is a major challenge for epidemiologists and disease ecologists. Migratory birds are often thought to be responsible for introducing some aviozoonotic pathogens such as West Nile and avian influenza viruses to a local area, but most information on how bird movement correlates with virus prevalence is anecdotal or indirect. We report that the prevalence of Buggy Creek virus (BCRV) infection in cimicid swallow bugs (Oeciacus vicarius), the principal invertebrate vector for this virus, was directly associated with the likelihood of movement by cliff swallows (Petrochelidon pyrrhonota), an amplifying host …


Ecological Correlates Of Buggy Creek Virus Infection In Oeciacus Vicarius, Southwestern Nebraska, 2004, Amy T. Moore, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown Jan 2007

Ecological Correlates Of Buggy Creek Virus Infection In Oeciacus Vicarius, Southwestern Nebraska, 2004, Amy T. Moore, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown

School of Natural Resources: Faculty Publications

Buggy Creek virus (family Togaviridae, genus Alphavirus, BCRV) is an alphavirus within the western equine encephalitis virus complex whose primary vector is the swallow bug, Oeciacus vicarius Horvath (Hemiptera: Cimicidae), an ectoparasite of the colonially nesting cliff swallow, Petrochelidon pyrrhonota, that is also a frequent host for the virus.We investigated ecological correlates of BCRV infection in 100-bug pools at 14 different swallow colony sites in southwestern Nebraska from summer 2004, by using plaque assay on Vero cells to identify cytopathic virus and reverse transcription-polymerase chain reaction to identify noncytopathic viral RNA. We found 26.7% of swallow bug pools …


Vouchering Dna-Barcoded Specimens: Test Of A Nondestructive Extraction Protocol For Terrestrial Arthropods, Daniel L. Rowley, Jonathan A. Coddington, Michael W. Gates, Allen L. Norrbom, Ronald A. Ochoa, Natalia J. Vandenberg, Matthew H. Greenstone Jan 2007

Vouchering Dna-Barcoded Specimens: Test Of A Nondestructive Extraction Protocol For Terrestrial Arthropods, Daniel L. Rowley, Jonathan A. Coddington, Michael W. Gates, Allen L. Norrbom, Ronald A. Ochoa, Natalia J. Vandenberg, Matthew H. Greenstone

USDA Systematic Entomology Laboratory

Morphology-based keys support accurate identification of many taxa. However, identification can be difficult for taxa that are either not well studied, very small, members of cryptic species complexes, or represented by immature stages. For such cases, DNA barcodes may provide diagnostic characters. Ecologists and evolutionary biologists deposit museum vouchers to document the species studied in their research. If DNA barcodes are to be used for identification, then both the DNA and the specimen from which it was extracted should be vouchered. We describe a protocol for the nondestructive extraction of DNA from terrestrial arthropods, using as examples members of the …

The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander

Faculty Research & Creative Activity

The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …

The Effects Of Nematode Infection And Mi-Mediated Resistance In Tomato (Solanum Lycopersicum) On Plant Fitness, Brandon P. Corbett Jan 2007

The Effects Of Nematode Infection And Mi-Mediated Resistance In Tomato (Solanum Lycopersicum) On Plant Fitness, Brandon P. Corbett

Inquiry: The University of Arkansas Undergraduate Research Journal

The Mi gene in tomato (Solanum lycopersicum) is a single, dominant resistance (R) gene that confers resistance against several species of insects and root-knot nematodes. Tis study examined the impact of root-knot nematode infestation and the plant growth and reproduction of near-isogenic tomato cultivars with and without Mi. The objectives of this experiment were to examine the potential fitness costs and benefits of the R gene-mediated herbivore resistance, and to explore the role of nematodes as a selection pressure favoring plants that carry Mi. Mi-mediated resistance dramatically reduced nematode reproduction on tomato. In the presence of nematodes, plants that carried …
