The First Vouchered Milliped Records For Prince Edward Island And Additional New Records From The Maritime Provinces Of Canada (Arthropoda: Diplopoda), Rowland M. Shelley, Mary E. Smith

Insecta Mundi

Four milliped species, substantiated by preserved voucher samples, are reported from Prince Edward Island, Canada. All are introduced European species that now occur widely in both Canada and the United States, and the panglobal Asian paradoxosomatid, Oxidus gracilis (C. L. Koch, 1847), is listed as probable. Choneiulus palmatus (Némec, 1895) (Julida: Blaniulidae) is newly recorded from New Brunswick, and four representatives of the Julidae are cited from Nova Scotia. Discovery of Cylindroiulus punctatus (Leach, 1815) (Julidae) in this province constitutes the second record from both Canada and North America, the other being in Newfoundland.

Efficacy Of Genetically Modified Bt Toxins Against Insects With Different Genetic Mechanisms Of Resistance, Bruce E. Tabashnik, Fangneng P. Huang, Mukti N. Ghimire, B. Rogers Leonard, Blair D. Siegfried, Murugesan Rangasamy, Yajun Yang, Yidong Wu, Linda J. Gahan, David G. Heckel, Alejandro Bravo, Mario Soberón

Department of Entomology: Faculty Publications

Transgenic crops that produce Bacillus thuringiensis (Bt) toxins are grown widely for pest control, but insect adaptation can reduce their efficacy. The genetically modified Bt toxins Cry1AbMod and Cry1AcMod were designed to counter insect resistance to native Bt toxins Cry1Ab and Cry1Ac. Previous results suggested that the modified toxins would be effective only if resistance was linked with mutations in genes encoding toxin-binding cadherin proteins. Here we report evidence from five major crop pests refuting this hypothesis. Relative to native toxins, the potency of modified toxins was > 350-fold higher against resistant strains of Plutella xylostella and Ostrinia nubilalis …

Characterization Of The Tolerance Response In The Soybean Ks4202 To Aphis Glycines Matsumura, Travis J. Prochaska

Department of Entomology: Dissertations, Theses, and Student Research

Since the introduction of the soybean aphid, Aphis glycines Matsumura, to the soybean growing regions of the United States, the soybean aphid has caused considerable economic damage and yield loss to soybean growers. The objectives of this research were to evaluate selected genotypes for resistance to the soybean aphid and characterize transcriptional changes in response to aphid feeding to better understand the underlying tolerant mechanism(s) in KS4202 and genes contributing to its tolerance response. A field study (2009) was conducted to evaluate selected soybean genotypes during their reproductive stages for resistance to A. glycines. The economic injury level (EIL) …

Cost-Effective Binomial Sequential Sampling Of Western Bean Cutworm, Striacosta Albicosta (Lepidoptera: Noctuidae), Egg Masses In Corn, S. Paula-Moraes, E. C. Burkness, Thomas E. Hunt, Robert Wright, Gary Hein, W. D. Hutchinson

Department of Entomology: Faculty Publications

Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), is a native pest of dry beans (Phaseolus vulgaris L.) and corn (Zea mays L.). As a result of larval feeding damage on corn ears, S. albicosta has a narrow treatment window; thus, early detection of the pest in the field is essential, and egg mass sampling has become a popular monitoring tool. Three action thresholds for field and sweet corn currently are used by crop consultants, including 4% of plants infested with egg masses on sweet corn in the silking-tasseling stage, 8% of plants infested with egg masses on field corn with …

Ecology Of Ticks (Acari: Ixodidae) In Shelterbelts Of Southeastern Nebraska, Matthew W. Yans

Department of Entomology: Dissertations, Theses, and Student Research

Shelterbelts in the agricultural landscape provide valuable habitat to a variety of animals that in turn may be hosts to ixodid ticks. The purpose of this study is to determine if shelterbelt associated factors influence tick ecology. In 2010 and 2011, ticks were collected from several shelterbelts in southeast Nebraska in Lancaster and Saunders counties. Four tick species were identified.

Adjacent land use, shelterbelt composition, and time of day were all factors which did not influence the number of questing ticks collected. Differences in relation to aspect and distance from the shelterbelt were significant. The east side had continually higher …

Dung Beetle Ecology: Habitat And Food Preference, Hypoxia Tolerance, And Genetic Variation, Sean Doyle Whipple

Department of Entomology: Dissertations, Theses, and Student Research

Four studies were conducted on dung beetles (Coleoptera: Scarabaeidae), which are insects of great ecological and economic importance. Range management practices were found to impact dung beetle diversity and abundance. While sampling on organic and conventionally managed ranches in Nebraska, 93% (5,767) of total dung beetle capture was from the organically managed ranch. Only 480 dung beetles (7% of total) were collected from the conventionally managed ranch. Results indicated that organic ranching had increased numbers and diversity of dung beetles.

Comparison of the attractiveness of native and exotic herbivore, carnivore, and omnivore dung yielded 9,089 dung beetles from 15 species. …

Gravesoil Microbial Community Structure During Carcass Decomposition, Amy E. Maile

Department of Entomology: Dissertations, Theses, and Student Research

Dead bodies placed on soil represent unique challenges for investigators. Although processes in soils can be used to estimate postmortem interval, we know very little about how carcasses and insects affect gravesoil microbial communities.

To address this, the current project was composed of two experiments. Experiment one was conducted to investigate the effect of surface type on carcass decomposition and evaluate soil ecology methods. Experiment two was conducted to investigate the presence of an insect population (Lucilia sericata Meigen) on gravesoil microbial communities. Both experiments were conducted in a laboratory setting using freshly killed mouse carcasses. Mouse carcasses were …

New Records Of Carrion Beetles In Nebraska Reveal Increased Presence Of The American Burying Beetle, Nicrophorus Americanus Olivier (Coleoptera: Silphidae), Jessica Jurzenski, Daniel G. Snethen, Mathew L. Brust, W. Wyatt Hoback

Great Plains Research: A Journal of Natural and Social Sciences

Surveys for the American burying beetle, Nicrophorus americanus Olivier (Silphidae), between 2001 and 2010 in Nebraska resulted in 11 new county records for this endangered species and 465 new county records for 14 other silphid species. A total of 5,212 American burying beetles were captured in more than 1,500 different locations. Using mark-recapture data, we estimated the population size of the American burying beetle (ABB) for six counties in the Sandhills. Blaine County (2003) had the largest population, with an estimated 56 ABBs per km² (1,338 ± 272 ABBs). The remaining estimates were between 2 and 36 ABBs per …

The Milliped Order Glomeridesmida (Diplopoda: Pentazonia: Limacomorpha) In Oceania, The East Indies, And Southeastern Asia; First Records From Palau, The Philippines, Vanuatu, New Britain, The Island Of New Guinea, Cambodia, Thailand, And Borneo And Sulawesi, Indonesia, Rowland M. Shelley

Insecta Mundi

The taxonomically neglected milliped order Glomeridesmida and family Glomeridesmidae (infraclass Pentazonia, superorder Limacomorpha) inhabit 21, rather than seven, regions of the world, being newly recorded from Thailand; Cambodia; the Republics of Palau, the Philippines, and Vanuatu; New Britain, Bismarck Archipelago; the Island of New Guinea (both West Papua [formerly Irian Jaya], Indonesia, and Papua New Guinea); and Sulawesi and Borneo, Indonesia. Occurrence in Fiji is confirmed with two additional samples, and discovery is predicted in southern China, Myanmar, and perhaps Madagascar. Coupled with published localities, these records suggest subcontinuous (super)ordinal and familial ranges extending some 12,480 km (7,800 mi) southeastward …
