Characterizing The Epidemiology Of Bluetongue And Epizootic Hemorrhagic Disease Virus In Louisiana, 2020 Louisiana State University and Agricultural and Mechanical College
Characterizing The Epidemiology Of Bluetongue And Epizootic Hemorrhagic Disease Virus In Louisiana, Michael Edward Becker
LSU Doctoral Dissertations
Bluetongue virus (BTV) and Epizootic Hemorrhagic Disease Virus (EHDV) are arthropod-borne viruses (Reoviridae; Orbivirus) transmitted by biting midges in the genus Culicoides. These viruses cause hemorrhagic disease and induce serious morbidity and mortality rates in wild and captive deer. Cattle are normally asymptomatic but serve as the reservoir/amplifying host for these viruses and play an important role in the transmission cycle. The objectives of this study were to characterize the epidemiology of these viruses as they relate to white-tailed deer and cattle, evaluate different trap types for collecting Culicoides midges, and determine if these viruses can be detected in ...
Ant Recruitment To Salt Along Chicago’S Urban Gradient, 2020 Lake Forest College
Ant Recruitment To Salt Along Chicago’S Urban Gradient, Marco Andres Servin
Sodium is vital for maintaining osmotic balance, muscle activity, and nervous system function in many organisms. The availability of sodium can drastically impact populations within ecosystems. Salt content from human foods and salt from winter road treatments could increase Na+ availability. I hypothesize that Na+ availability is more limited when moving away from Chicago. I baited ants along two 50km transects extending West and North from downtown Chicago. Transects contained 10 evenly spaced forested sites. Baits were equally split between H20, 20% sugar, and 1% salt concentration. Thirteen ant species were collected, but only three species recruited to ...

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
Theses, Dissertations, and Student Research in Agronomy and Horticulture
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.
Impacts Of Commercial Biopesticides On Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) And Beneficial Insects, 2020 Louisiana State University and Agricultural and Mechanical College
Impacts Of Commercial Biopesticides On Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) And Beneficial Insects, Giovana Matos Franco
LSU Master's Theses
The crapemyrtle bark scale (CMBS), Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is an important pest of crapemyrtles, Lagerstromia spp. (Myrtales: Lythraceae) since its damage results in an unpleasant aesthetic. Current CMBS management methods depend heavily on pesticides which impact on beneficial insects. Biopesticides show potential for pest control, host specificity, and low impact towards non-target organisms. The objectives of my thesis were to determine (1) if biopesticides are effective against CMBS infestations when applied in different seasons, and (2) their effects towards coccinellids known to attack CMBS.
To test the efficacy of selected biopesticides, treatments were delivered to potted plants or ...

Voegtlin, David Onstad, David Hogg, David Ragsdale, Kelley Tilmon, Erin Hodgson, Christina Difonzo, Russell Groves, Christian Krupke, Joseph Laforest, Nicholas J. Selter, Emily Duerr, Benjamin Bradford, Glen L. Hartman
The initiation of the soybean aphid suction trap network (STN) in 2001 marked the beginning of a rich and fruitful collaborative effort that has produced a wealth of data about the soybean aphid, other insect species, and other organisms that make up the aerobiological “soup.” Collaboration among researchers, extension specialists, and agriculturalists has provided information about seasonal migration patterns of the soybean aphid and monitoring of other insect species. The physical collections of the “soup” have been stored and used for past research, and will serve as a foundation for future research.
Double-Stranded Rna Technology To Control Insect Pests: Current Status And Challenges, 2020 Ghent University
Double-Stranded Rna Technology To Control Insect Pests: Current Status And Challenges, Olivier Christiaens, Steve Whyard, Ana M. Vélez, Guy Smagghe
Faculty Publications: Department of Entomology
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 ...
Factors Influencing Wheat Curl Mite Aceria Tosichella Keifer Dispersal, 2020 University of Nebraska - Lincoln
Factors Influencing Wheat Curl Mite Aceria Tosichella Keifer Dispersal, Lindsay M. Overmyer
Dissertations and Student Research in Entomology
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 wheat is not ...
Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, 2020 University of Nebraska - Lincoln
Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, Jennifer Williams
Dissertations and Student Research in Entomology
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 ...

Mosquito Communities And Insect-Specific Viruses In A Heterogenous, Urban Landscape In Puerto Rico, Nicole Scavo
The goal of my thesis was to investigate the relationships between mosquito diversity, Aedes aegptyi populations, and socioeconomic factors (SEF) in an urban setting and to characterize the virome of Ae. aegypti in San Juan, Puerto Rico. Mosquitoes were collected in three periods during late 2018 and early 2019 and were identified to the species level. Socioeconomic factors were measured using foot surveys and U.S. Census data. Some Ae. aegypti females were processed for sequencing and sent to Quick Biology for RNA sequencing to identify viruses. Results showed a link between SEF and Ae. aegypti abundance as well as ...
Historical And Contemporary Variables Affecting The Range And Distribution Of Aedes Aegypti, The Yellow Fever Mosquito, In The United States, 2020 The University of Southern Mississippi
Historical And Contemporary Variables Affecting The Range And Distribution Of Aedes Aegypti, The Yellow Fever Mosquito, In The United States, Nicole Mackey
Aedes aegypti, the primary mosquito vector of the yellow fever virus, threatens global health by passing on this virus, as well as chikungunya, dengue, and Zika viruses. Through its natural tendency to live in highly urban areas and bite human hosts; understanding the factors that affect the historical and current range of the pest is invaluable (Gubler, 1998). Although these viruses are not normally found in the United States, lack of vaccinations and wide-spread presence of the mosquito could lead to these diseases being reintroduced with potentially devastating effects (Monath, 2001). To determine a partial historical range of A. aegypti ...
Sorghum Tolerance Of Phloem-Feeding Aphids, 2020 University of Nebraska - Lincoln
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 ...

Community-Wide Grasshopper Control, 2020 Utah State University
Community-Wide Grasshopper Control, Marion Murray
All Current Publications
Springtime, while grasshoppers are still nymphs, is the best time for communities or neighborhoods to work together to suppress grasshopper populations. Treating as wide an area as possible is the key to success. When grasshoppers become adults, they can travel great distances and may not remain in one area long enough for an insecticide to be effective.
