Comparative Analysis Of Viruses In Four Bee Species Collected From Agricultural, Urban, And Natural Landscapes, Tugce Olgun, Sydney Everhart, Troy D. Anderson, Judy Wu-Smart

Department of Entomology: Faculty Publications

Managed honey bees (Apis mellifera L.) and wild bees provide critical ecological services that shape and sustain natural, agricultural, and urban landscapes. In recent years, declines in bee populations have highlighted the importance of the pollination services they provide and the need for more research into the reasons for global bee losses. Several stressors cause declining populations of managed and wild bee species such as habitat degradation, pesticide exposure, and pathogens. Viruses, which have been implicated as a key stressor, are able to infect a wide range of species and can be transmitted both intra- and inter-specifically from infected …

Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein

UCARE: Research Products

To better understand the ecology and epidemiology of the wheat curl mite (Aceria tosichella Keifer) as a vector of wheat streak mosaic virus (WSMV), it is necessary to develop a method to confine the microscopic mites and their infection to specific areas of their host plants, particularly wheat and corn. In this study, corn was the plant of interest. The device developed for this mite-confining method was made by removing the lens of a phone camera lens clip and gluing a 2.5 cm x 4.5 cm piece of wood to the other arm of the clip. Clips were utilized by …

Nomenclatural Notes For The Erotylinae (Coleoptera: Erotylidae), Paul E. Skelley

Insecta Mundi

Several taxonomic and nomenclatural issues are reviewed, clarified, and resolved for multiple genera of the Erotylinae (Coleoptera: Erotylidae). Generic-group names discussed: Brachymerus Dejean, 1836, Cyphero­tylus Crotch, 1873, Cytorea Laporte, 1840, Erotylus Fabricius, 1775, Eudaemonius Lewis, 1887, Eutriplax Lewis, 1887, Gibbifer Voet, 1806, Neobarytopus Alvarenga, 1965, Neomorphoides Alvarenga, 1977, Ogcotriplax Heller, 1920, Paratritoma Gorham, 1888, Platichna Thomson, 1863, Pseudochrysomela Voet, 1806, Pseudotriplax Heller, 1920, Triplax Herbst, 1793, Tritomapara Alvarenga, 1970, Typocephalus Hope, 1841, and Xestus Wollaston, 1864.

Reviewing these issues resulted in a several nomenclatural actions. Eutriplax Lewis, 1887, was found to be an unnecessary replacement name for Eudaemonius Lewis, 1887. …

Comparative Effects Of Technical-Grade And Formulated Chlorantraniliprole To The Survivorship And Locomotor Activity Of The Honey Bee, Apis Mellifera (L.), Jennifer R. Williams, Daniel R. Swale, Troy D. Anderson

Department of Entomology: Faculty Publications

Background: The loss of honey bee colonies is a nationally recognized problem that demands attention from both the scientific community and the beekeeping industry. One outstanding threat is the unintended exposure of these pollinators to agricultural pesticides. Anthranilic diamides, such as chlorantraniliprole, are registered for use in stone and pome fruits, vegetables, turf, and grains. There are few publicly available studies that provide an analysis of chlorantraniliprole effects on the survivorship and locomotion activity of beneficial, pollinating insects such as honey bees. The data gathered in this study provide the acute toxicity, 30-day survivorship, and locomotor activity of honey …

Re-Evaluation Of Euchloe Olympia (W. H. Edwards, 1871 (Pieridae: Pierinae) From A Geographic And Taxonomic Perspective, Harry Pavulaan

The taxonomic status of regional populations of Euchloe olympia (W. H. Edwards, 1871) is reevaluated here. A review of pertinent literature and a critique of Clench & Opler (1983) are provided. The taxon rosa and two distinct populations of the Great Lakes “dune form” are each proposed for recognition at subspecific rank. The status of synonym anniha Ebner (1970) is addressed.

First Record Of Dactylopius Confusus (Cockerell, 1929) (Hemiptera: Coccomorpha: Dactylopiidae) In Michoacan, Mexico, Arturo Ramírez-Cruz, Héctor González-Hernández, Christof F. Stumpf

Insecta Mundi

In April 2017, several scale insect specimens in the family Dactylopiidae were collected from infested cladodes of wild Opuntia tomentosa Salm-Dyck, 1822 (Cactaceae) in the outskirts of Morelia City, Michoacan, Mexico. The specimens were identified as Dactylopius confusus (Cockerell, 1929) (Hemiptera: Coccomorpha: Dac­tylopiidae). In this article, the presence of D. confusus in Michoacan state, Mexico, is recorded for the first time. A subsequent finding of D. confusus on Opuntia ficus-indica (L.) Mill., (1768) (Cactaceae) in October 2019 was confirmed with 18S rDNA and 28S rDNA.

Effects Of Pesticide Residue Accumulation On Honey Bee (Apis Mellifera L.) Development And Implications For Hive Management, Jennifer Weisbrod

Department of Entomology: Dissertations, Theses, and Student Research

Honey bee (Apis mellifera L.) colonies face annual declines of 40% in the United States. Pesticides play a role in these losses. Pesticide residues picked up from the environment as well as beekeeper-applied compounds may accumulate within the hive. The effects of pesticide accumulation in comb on bee health mitigation of accumulation have not been well-studied. To examine pesticide exposure on health and development, chlorothalonil and the amitraz metabolite N-(2,4-dimethylphenyl) formamidine (DMPF), two pesticides found in hive products, were applied to brood comb. Queen bees were caged onto treated and control comb and egg laying and development were assessed. …

A Deeper Meaning For Shallow-Level Phylogenomic Studies: Nested Anchored Hybrid Enrichment Offers Great Promise For Resolving The Tiger Moth Tree Of Life (Lepidoptera: Erebidae: Arctiinae), Nicolas J. Dowdy, Shannon Keating, Alan R. Lemmon, Emily M. Lemmon, William E. Conner, Clare H. Scott Chialvo, Susan Weller, Rebecca B. Simmons, Melissa S. Sisson, Jennifer M. Zaspel

Department of Entomology: Faculty Publications

Anchored hybrid enrichment (AHE) has emerged as a powerful tool for uncovering the evolutionary relationships within many taxonomic groups. AHE probe sets have been developed for a variety of insect groups, though none have yet been shown to be capable of simultaneously resolving deep and very shallow (e.g., intraspecific) divergences. In this study, we present NOC1, a new AHE probe set (730 loci) for Lepidoptera specialized for tiger moths and assess its ability to deliver phylogenetic utility at all taxonomic levels. We test the NOC1 probe set with 142 individuals from 116 species sampled from all the major lineages of …

Evaluating Larval Movement And Infestation Of Soybean Gall Midge, Genereuse Turabawe, Débora Goulart Montezano, Anthony J. Mcmechan

UCARE: Research Products

Soybean gall midge (SGM) Resseliellamaxima Gagnéis a newly identified insect pest of soybean (Gagnéet al 2019). As of August, 2019 a total of 92 counties across five midwestern states (Fig. 1) documented as infested. Heavily injured soybean fields show visible signs of dead or dying plants (Fig. 2a), causing significant economic losses for farmers.

Heavily injured soybean plants often die prematurely with several different larval stages (Fig. 2b) still feeding within the plant. Significant concern have been raised about the role of these larvae in infesting adjacent healthy plants.

To better understand the behavior and potential for larval infestation a …

Extreme Fire As A Management Tool To Combat Regime Shifts In The Range Of The Endangered American Burying Beetle, Alison K. Ludwig, Daniel R. Uden, Dirac Twidwell

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

This study is focused on the population of federally-endangered American burying beetles in south-central Nebraska. It is focused on changes in land cover over time and at several levels of spatial scale, and how management efforts are impacting both the beetle and a changing landscape. Our findings are applicable to a large portion of the Great Plains, which is undergoing the same shift from grassland to woodland, and to areas where the beetle is still found.

An Annotated Bibliography Of Archaeoentomology, Diana Gallagher

Department of Entomology: Distance Master of Science Projects

For my Master’s Degree Project, I have undertaken to compile an annotated bibliography of a selection of the current literature on archaeoentomology. While not exhaustive by any means, it is designed to cover the main topics of interest to entomologists and archaeologists working in this odd, dark corner at the intersection of these two disciplines. I have found many obscure works but some publications are not available without a trip to the Royal Society’s library in London or the expenditure of far more funds than I can justify. Still, the goal is to provide in one place, a list, as …

A Phenotypic Comparison Of Regional Populations Of Hemileuca Maia (Drury, 1773) With Designations Of New Subspecies (Bombycoidea, Saturniidae, Hemileucinae), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

Following refinement of the type locality of Hemileuca maia to the Long Island Pine Barrens of New York State by the author (Pavulaan, 2020), an evaluation of phenotypic characters of regional populations of H. maia is presented. The Long Island population is the nominotypical subspecies. Populations in southeastern coastal New England and offshore islands are presently considered nominotypical maia. However, several continental inland populations show evidence of subspecific variation. Four new subspecies are designated. Detailed phenotypic information of other interior regions is lacking.

Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, Jennifer Williams

Department of Entomology: Dissertations, Theses, and Student Research

One outstanding threat to the honey bee, Apis mellifera L., is the unintended exposure of these pollinators to agricultural pesticides. Anthranilic diamides, such as chlorantraniliprole, work in target pests through activation of the ryanodine receptor causing rapid feeding cessation, lethargy, paralysis, and eventual death. Chlorantraniliprole exhibits low acute toxicity to honey bees but relatively little information exists regarding effects of chlorantraniliprole exposure beyond mortality. The acute toxicity and metabolic detoxification enzyme activities following oral exposure were determined in the honey bee and the model crop pest, the fall armyworm (Spodoptera frugiperda, J.E. Smith). Additionally, chlorantraniliprole effects on honey bee …

Sorghum Tolerance Of Phloem-Feeding Aphids, Earl Agpawa, Sajjan Grover, Joe Louis

UCARE: Research Products

Aphids are phloem sap-feeding insects that negatively affects plant productivity. With short generation times, new aphid biotypes may arise either in response to pesticide use or through other factors. Additional biotypes can cause serious damage to plants compared to others. Whereas others can become highly resistant to methods of pest control. One possible solution to this problem is to focus on the plant itself, or host plant resistance. Plant tolerance is one of the plant resistance categories in which the plant is capable of functioning normally and remain relatively unharmed and stable in response to insect herbivory without harming the …

Factors Influencing Wheat Curl Mite Aceria Tosichella Keifer Dispersal, Lindsay M. Overmyer

Department of Entomology: Dissertations, Theses, and Student Research

The wheat curl mite (Aceria tosichella Keifer) (WCM) is a vector of three plant viruses to wheat (Triticum aestivum L.) including: Wheat streak mosaic virus (WSMV), Triticum mosaic virus (TriMV), and High Plains wheat mosaic virus. This wheat-mite-virus complex causes significant yield loss in winter wheat across the Great Plains. Management of WCM host plants during the time between wheat harvest and planting of the new wheat crop (the green bridge) is critical in reducing potential risk and loss from this complex. The primary green bridge host, in the central Great Plains, is volunteer wheat. If volunteer …

Double-Stranded Rna Technology To Control Insect Pests: Current Status And Challenges, Olivier Christiaens, Steve Whyard, Ana M. Vélez, Guy Smagghe

Department of Entomology: Faculty Publications

Exploiting the RNA interference (RNAi) gene mechanism to silence essential genes in pest insects, leading to toxic effects, has surfaced as a promising new control strategy in the past decade. While the first commercial RNAi-based products are currently coming to market, the application against a wide range of insect species is still hindered by a number of challenges. In this review, we discuss the current status of these RNAi- based products and the different delivery strategies by which insects can be targeted by the RNAi-triggering double-stranded RNA (dsRNA) molecules. Furthermore, this review also addresses a number of physiological and cellular …

Effect Of Temperature On Plant Resistance To Arthropod Pests, James R. Nechols, Ashley R. Hough, David C. Margolies, John R. Ruberson, Brian P. Mccornack, Brett K. Sandercock, Leigh Murray

Department of Entomology: Faculty Publications

Temperature has a strong influence on the development, survival, and fecundity of herbivorous arthropods, and it plays a key role in regulating the growth and development of their host plants. In addition, temperature affects the production of plant secondary chemicals as well as structural characteristics used for defense against herbivores. Thus, temperature has potentially important implications for host plant resistance. Because temperature directly impacts arthropod pests, both positively and negatively, distinguishing direct effects from indirect effects mediated through host plants poses a challenge for researchers and practitioners. A more comprehensive understanding of how temperature affects plant resistance specifically, and arthropod …

Distortion Of The Local Magnetic Field Appears To Neither Disrupt Nocturnal Navigation Nor Cue Shelter Recognition In The Amblypygid Paraphrynus Laevifrons, Daniel D. Wiegmann, Patrick Casto, Eileen Hebets, Verner P. Bingman

Eileen Hebets Publications

Many arthropods are known to be sensitive to the geomagnetic field and exploit the field to solve spatial problems. The polarity of the geomagnetic field is used, for instance, as an orientation cue by leafcutter ants as they travel on engineered trails in a rainforest and by Drosophila larvae as they move short distances in search of food. A ubiquitous orientation cue like the geomagnetic field may be especially useful in complex, cluttered environments like rainforests, where the reliability of celestial cues used to navigate in more open environments may be poor. The neotropical amblypygid Paraphrynus laevifrons is a nocturnal …
