Octapartite Negative-Sense Rna Genome Of High Plains Wheat Mosaic Virus Encodes Two Suppressors Of Rna Silencing, Adarsh K. Gupta, Gary L. Hein, Robert A. Graybosch, Satyanarayana Tatineni

Department of Entomology: Faculty Publications

High Plains wheat mosaic virus (HPWMoV, genus Emaravirus; family Fimoviridae), transmitted by the wheat curl mite (Aceria tosichella Keifer), harbors a monocistronic octapartite single-stranded negative-sense RNA genome. In this study, putative proteins encoded by HPWMoV genomic RNAs 2–8 were screened for potential RNA silencing suppression activity by using a green fluorescent protein-based reporter agroinfiltration assay. We found that proteins encoded by RNAs 7 (P7) and 8 (P8) suppressed silencing induced by single- or doublestranded RNAs and efficiently suppressed the transitive pathway of RNA silencing. Additionally, a Wheat streak mosaic virus (WSMV, genus Tritimovirus; family Potyviridae …

Nebraska Invasive Plants Field Guide, Nebraska Invasive Species Program

Nebraska Invasive Species Program

Invasive species are plants, animals or pathogens that are non-native to an ecosystem. They cause harm to the economy, environment or human health. They negatively affect native species and ecosystems and interfere with outdoor recreation opportunities. This guide identifies federal and state-listed noxious weeds. Federal noxious weeds are regulated by the U.S. Department of Agriculture; State noxious weeds are regulated by the Nebraska Department of Agriculture, Animal and Plant Health Protection, Noxious Weed Program. Aquatic invasive species are listed and regulated by Nebraska Game and Parks Commission.

Rnai-Mediated Knockdown Of Vatpase Subunits Affects Survival And Reproduction Of Bed Bugs (Hemiptera: Cimicidae), Sanjay Basnet, Shripat T. Kamble

Department of Entomology: Faculty Publications

The common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae) has resurged as one of the most troublesome household pests affecting people across the globe. Bed bug infestations have increased in recent years primarily due to the evolution of insecticide resistance and the insect’s ability to hitchhike with travelers. vATPases are one of the most evolutionarily conserved holoenzymes in eukaryotes, which are mainly involved in proton transport across the plasma membranes and intracellu­lar organelles. RNA interference (RNAi) has been developed as a promising tool for insect control. In this study, we used RNAi as an approach to knock down subunits A …

Altering Plant Defenses: Herbivore-Associated Molecular Patterns And Effector Arsenal Of Chewing Herbivores, Saumik Basu, Suresh Varsani, Joe Louis

Department of Entomology: Faculty Publications

Chewing herbivores, such as caterpillars and beetles, while feeding on the host plant, cause extensive tissue damage and release a wide array of cues to alter plant defenses. Consequently, the cues can have both beneficial and detrimental impacts on the chewing herbivores. Herbivore-associated molecular patterns (HAMPs) are molecules produced by herbivorous insects that aid them to elicit plant defenses leading to impairment of insect growth, while effectors suppress plant defenses and contribute to increased susceptibility to subsequent feeding by chewing herbivores. Besides secretions that originate from glands (e.g., saliva) and fore- and midgut regions (e.g., oral secretions) of chewing herbivores, …

Mosquito Abatement Monitoring: West Nile In Los Angeles County, Elisa Gonzalez

Department of Entomology: Distance Master of Science Projects

West Nile virus (WNV) has become established across the U.S. with heightened activity causing significant human illness. Monitoring methods to predict the risk of human infection are urgently need to initiate timely preventative measures and justify the expense of implementing costly or unpopular control measures, such as aerial spraying or curfews. This research outlines several ways to further improve the productive power of monitoring mosquitoes. These results demonstrate that mosquito monitoring provides a valuable public health tool for assessing the risk of human arboviral infections, allocating limited public health resources, and justifying emergency control actions.

A key challenge has been …

Some Aspects Of Woodpecker Predation On The Spruce Beetle In Colorado, Steven R. Helm

Department of Entomology: Distance Master of Science Projects

Historic data on predation by woodpeckers, primarily the American three-toed woodpecker (Picoides dorsalis), on epidemic levels of the spruce beetle (Dendroctonus rufipennis) in Engelmann spruce (Picea engelmannii) forests of Colorado are analyzed in this report. Significant differences in beetle consumption by male and female woodpeckers as well as seasonal differences in beetle consumption by woodpeckers in general were discovered through statistical analyses. Potential ecological explanations for observed differences are discussed.

Impact Of Timing And Method Of Virus Inoculation On The Severity Of Wheat Streak Mosaic Disease, E. N. Wosula, Anthony J. Mcmechan, Allison L. Knoell, Satyanarayana Tatineni, Stephen N. Wegulo, Gary L. Hein

Department of Entomology: Faculty Publications

Wheat streak mosaic virus (WSMV), transmitted by the wheat curl mite Aceria tosichella, frequently causes significant yield loss in winter wheat throughout the Great Plains of the United States. A field study was conducted in the 2013–14 and 2014–15 growing seasons to compare the impact of timing of WSMV inoculation (early fall, late fall, or early spring) and method of inoculation (mite or mechanical) on susceptibility of winter wheat cultivars Mace (resistant) and Overland (susceptible). Relative chlorophyll content, WSMV incidence, and yield components were determined. The greatest WSMV infection occurred for Overland, with the early fall inoculations resulting in …

Escarabajos Longicornios (Coleoptera: Cerambycidae Y Disteniidae) Del Parque Nacional Darién, Panamá, Alfredo Lanuza-Garay, Alonso Santos Murgas

Insecta Mundi

Darién National Park (PND), a natural connection between South and Central America, is the largest national park not only in Panama but in all of Central America. Due to its strategic geographical situation, it is a place for the interchange of the North and South American fauna, where endemic invertebrates and vertebrates are very abundant. Through the use of malaise traps and light traps placed at different points within the PND, 183 individuals of 87 species of longicorn beetles in the families Cerambycidae and Disteniidae were collected. Also, four species of longhorn beetles (Cerambycidae) are reported for the first time …

Insecta Mundi

Brachyplatys subaeneus (Westwood) (Hemiptera: Plataspidae) is a species of true bug native to Asia that was reported in 2016 for the first time in Panama and the Americas. This species is an invasive organism considered as a potential pest for pigeon pea (Cajanus cajan (L.) Huth) and other legume crops. As no additional research has been done on this bug since the original report, this study seeks to generate additional information regarding its spatial distribution in Panama, focusing along the Pacific coast from Torti, East Panama, to Chitre, Herrera province.

Four Submarginal Cells On A Forewing Of Melitoma Taurea (Say) (Hymenoptera: Apidae), And A Summary Of Known Records Of Atypical And Variable Numbers Of Submarginal Cells, Eugene J. Scarpulla

Insecta Mundi

A specimen of Melitoma taurea (Say) (Hymenoptera: Apidae) was captured on Hart-Miller Island, Chesapeake Bay, Baltimore County, Maryland. The specimen possessed the typical three submarginal cells on the right forewing but exhibited four submarginal cells on the left forewing due to the presence of an additional submarginal crossvein dividing the second submarginal cell. The presence of four submarginal cells is a rare occurrence in bees. Besides documenting this occurrence, this paper presents a summary of known published and previously unpublished records of atypical and variable numbers of submarginal cells. Published records were found for 66 species: Colletidae (1), Andrenidae (28), …
