Lepidoptera Pests Of Sapodilla (Manilkara Zapota (L.) Van Royen) In South Florida, With Some Comments On Life History And Natural Control, Jose I. Martinez, Jonathan H. Crane, Jeff Wasielewski, Jacqueline Y. Miller, Daniel Carrillo

Insecta Mundi

Sapodilla (Manilkara zapota (L.) van Royen) is originally from the Neotropics, and has become one of the most important tropical crops in the last few decades. The major producers include India, Mexico, Sri Lanka, the Philippines, Venezuela and Guatemala. It is also a minor crop in the United States, specifically South Florida. In 2015, it was reported that Florida growers suffered a loss of up to 80% of their production due to lepidopteran pests. We surveyed two sapodilla orchards weekly in South Florida for about six months. We collected 1,070 lepidopteran individuals (i.e., larvae, pupae and adults) belonging ...

Differential Analysis Of Individual Centruroides Vittatus Venom, 2019 Kennesaw State University

Differential Analysis Of Individual Centruroides Vittatus Venom

Symposium of Student Scholars

Scorpions are well known, venomous arthropods (Class: Arachnida, Order: Scorpiones). Their venom is composed of neurotoxins, proteases and cytotoxic peptides which plays a major role in toxic components such as inflammatory, antimicrobial and hemolytic activity. Venom is key for the survival of scorpions as it is involved in defense against prey and in feeding on predators. Centruroides vittatus (bark scorpion) is commonly found in North America, with habitat ranges from Nebraska to southern Texas. For this study, scorpions were harvested from Laredo, Texas (27˚57’ N, 99˚43’ W), held in captivity for 4 months and fed a consistent diet ...


A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram 2019 University of Nebraska-Lincoln

A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram

Dissertations and Student Research in Entomology

To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.

A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and ...

Sonenshine, Francisco Pasada-Florez, Noble I.I. Noble, Joseph Mowery, Conner J. Gulbronson, Gary R. Bauchan 2019 Old Dominion University

Insights Into The Feeding Behaviors And Biomechanics Of Varroa Destructor Mites On Honey Bee Pupae Using Electropenetrography And Histology, Andrew Y. Li, Steven C. Cook, Daniel E. Sonenshine, Francisco Pasada-Florez, Noble I.I. Noble, Joseph Mowery, Conner J. Gulbronson, Gary R. Bauchan

Biological Sciences Faculty Publications

Feeding behaviors and biomechanics of female Varroa destructor mites are revealed from AC-DC electropenetrography (EPG) recordings of mites feeding from Apis mellifera honey bee pupae and histology of mite internal ingestion apparatus. EPG signals characteristic of arthropod suction feeding (ingestion) were identified for mites that fed on pupae during overnight recordings. Ingestion by these mites was confirmed afterwards by observing internally fluorescent microbeads previously injected into their hosts. Micrographs of internal ingestion apparatus illustrate the connection between a gnathosomal tube and a pharyngeal lumen, which is surrounded by alternating dilator and constrictor muscles. Inspection of EPG signals showed the muscularized ...

Using Adults To Monitor Rnai Susceptibility Of Western Corn Rootworm, Diabrotica Virgifera Virgifera Leconte, Field Populations, Matthew Welter 2019 University of Nebraska - Lincoln

Using Adults To Monitor Rnai Susceptibility Of Western Corn Rootworm, Diabrotica Virgifera Virgifera Leconte, Field Populations, Matthew Welter

Dissertations and Student Research in Entomology

The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is the most damaging corn pest in the U.S. Corn Belt, costing producers over $1 billion annually in control and damage costs. Currently, corn producers rely on three control strategies for WCR management: crop rotation, chemical insecticides, and transgenic corn expressing Bacillus thuringiensis Berliner (Bt) proteins. Populations of WCR have evolved resistance to all of these tactics, limiting effective control strategies for producers. RNA interference (RNAi), is the newest mode of action developed for WCR management. In July 2017, the first RNAi plant-incorporated protectant (PIP) corn product was approved for ...


Spatial And Temporal Variation In The Aquatic Invertebrate Community Structure Of Rock Pools Along The Penobscot River, Maine, Chase R. Gagne 2019 University of Maine

Spatial And Temporal Variation In The Aquatic Invertebrate Community Structure Of Rock Pools Along The Penobscot River, Maine, Chase R. Gagne

Electronic Theses and Dissertations

Pools of water that form in the fissures and depressions of rock outcrops, known as rock pools, are fairly common aquatic habitats that can easily be found along the rocky banks of many of Maine’s major rivers. In general, rock pools and the aquatic invertebrates inhabiting them have received little research attention and, though ubiquitous, have never been studied in Maine. My research addressed this knowledge gap by surveying 40 rock pools at four sites along the Penobscot River in Maine. The rock pools themselves had highly variable environmental characteristics and differed across sites and over time, especially in ...


Peach Twig Borer Mating Disruption, Marion Murray, Diane G. Alston 2019 Utah State University

Peach Twig Borer Mating Disruption, Marion Murray, Diane G. Alston

All Current Publications

Mating disruption became commercially available in the early 1990s, and was adopted by many Utah growers about a decade later. Use of this pest management technology can be daunting due to high up-front costs and monitoring requirements; however, after two to three seasons of use, the cost of mating disruption is the same or even less than conventional pest management.


Drivers Of Ant Composition, Richness, And Trophic Guilds In Neotropical Iron Ore Cavities, Rodrigo A. Castro-Souza, Thais G. Pellegrini, Marconi Souza-Silva, Rodrigo L. Ferreira 2019 Universidade Federal de Lavras

Drivers Of Ant Composition, Richness, And Trophic Guilds In Neotropical Iron Ore Cavities, Rodrigo A. Castro-Souza, Thais G. Pellegrini, Marconi Souza-Silva, Rodrigo L. Ferreira

International Journal of Speleology

Subterranean habitats may be considered limiting for animal colonization, especially for ants, due to permanent darkness and mainly because of oligotrophic conditions. While not as deep as limestone caves, iron ore caves and other subterranean habitats may be more available for colonization because of their shallower depth. We use the richness and composition of ants to assess how differences in habitat structure affect the biodiversity and ecosystem function between cavities and surrounding epigean landscapes. We predicted that the distribution of ants would be different because of the variation in habitat structure and cavity conditions may act as a filter for ...


Transcriptional Responses Of Soybean Aphids To Sublethal Insecticide Exposure, Laramy S. Enders, Leslie C. Rault, Tiffany Heng-Moss, Blair Siegfried, Nicholas J. Miller 2019 University of Nebraska-Lincoln

Transcriptional Responses Of Soybean Aphids To Sublethal Insecticide Exposure, Laramy S. Enders, Leslie C. Rault, Tiffany Heng-Moss, Blair Siegfried, Nicholas J. Miller

Faculty Publications: Department of Entomology

Insecticides are a key tool in the management of many insect pests of agriculture, including soybean aphids. The selection imposed by insecticide use has often lead to the evolution of resistance by the target pest through enhanced detoxification mechanisms. We hypothesised that exposure of insecticide-susceptible aphids to sublethal doses of insecticides would result in the up-regulation of genes involved in detoxification of insecticides, revealing the genes upon which selection might act in the field. We used the soybean aphid biotype 1 reference genome, version 6.0 as a reference to analyze RNA-Seq data. We identified multiple genes with potential detoxification ...

DIRECTOR'S NOTE

Each fall, the Honors Program at Olivet Nazarene University admits a small number of academically gifted students into its freshman class. From the moment they set foot on our campus, these women and men join a community of scholars, and together they read, reflect upon, and discuss the most important ideas of the past and present—all within a Christian fellowship. The first two years of the program involve a series of Honors courses, taught by a team of faculty and modeled on the historic “old-time college,” where small class relationships, interdisciplinary discussion, and debate prevailed.

#41 - A Preliminary Assessment Of Native Pollinator Attraction To Bee Hotels In Northeast Georgia, Jada Tipton, Amelia Arthur, David Patterson, Rosann Kent, Zach Pilgrim 2019 University of North Georgia

#41 - A Preliminary Assessment Of Native Pollinator Attraction To Bee Hotels In Northeast Georgia, Jada Tipton, Amelia Arthur, David Patterson, Rosann Kent, Zach Pilgrim

Georgia Undergraduate Research Conference (GURC)

Native pollinators are an essential component of ecosystems as they ensure a stable and diverse vegetation community. However, populations at local, regional and global scales are currently threatened and will potentially undergo a large-scale extinction. One of the primary challenges is the constant threat of nesting habitat degradation. These structures are especially important in well-manicured areas where there is a lack of natural debris (e.g., decaying logs, leaves). In this study, we created “Bee Hotels” to serve as pre-constructed native pollinator habitats at UNG’s Appalachian Studies Center in The Historic Vickery House gardens. We placed these structures near ...


#42 - Deterrence Of Ants By Chemical Compounds From Six Southeastern Plants, Jose Alcalde, Evan Lampert, Tom Diggs 2019 University of North Georgia

#42 - Deterrence Of Ants By Chemical Compounds From Six Southeastern Plants, Jose Alcalde, Evan Lampert, Tom Diggs

Georgia Undergraduate Research Conference (GURC)

Ant interactions with plants are diverse; therefore, one of the most important aspects of ant-plant interactions is the exposure of ants to plant compounds. These compounds can serve as cues to either enhance or deter recruitment of ants to food. The purpose of this experiment is to measure the recruitment of ants to extracts that were made from six different southeastern native plants, all of which display a wide range of chemical diversity. Seven different extracts were mixed using a sugar solution. Six of the extracts had the dried leaf material of the plants Solidago altissimus, Verbesina virginica, Callicarpa americana ...

#15 - Assessing The Presence Of Wolbachia In The Mosquito Populations Of Northeast Georgia, Usa, Madison Embrick, Emma Rogers, Evan Lampert, Davison T. Sangweme, Mason Carlisle

Georgia Undergraduate Research Conference (GURC)

Wolbachia, a Gram-negative bacterium that infects mosquitoes along with other arthropods, can suppress the spread of microfilaria through reducing the populations of mosquitoes that carry the heartworms. Historically, research has been conducted to use in the prevention of infections from parasites or viruses like Zika or yellow fever. It is important to understand ways of preventing the various infections from occurring not only by host prevention but through vector prevention or suppression. In the summer of 2018, a total of thirty-five adult female mosquitoes were collected in Oakwood, Georgia at the University of North Georgia in two locations between May ...

Comparing Plant Diversity on Animal Associations

Sean Eagan, Evan Lampert, Tom Diggs

It is known that climate change has an impact on community interactions and structure. Understanding the associations between plants and animals is pivotal to begin comprehending how future communities will be impacted. Competing hypothesis, with mixed results, have been previously tested on plant diversity and their associated herbivores. Oconee State Park located in South Carolina provides a range of ecosystems for comparison and understanding the community interactions between plants and their possible herbivores. Data collected using line transects and 16 quadrants respectively from four different ecosystems occurred in ...
