Spotted Wing Drosophila (Drosophila Suzukii) In Arkansas: Winter Morphs, Wild Hosts, And Fungal Control, Rosalee Knipp

Theses and Dissertations

Drosophila suzukii (Matsumura), or spotted wing drosophila (SWD), is an invasive fruit fly pest that was first found in the United States in 2008. Unlike native Drosophila, SWD females have a serrated ovipositor that allows them to attack ripening fruit. Since its introduction, it is unclear how and where they overwinter in Arkansas, what local hosts they utilize and what potential alternative tactics can be used to combat this pest. In states north of Arkansas, winter morphs (WM) of SWD are larger, darker pigmented, and can survive colder temperatures than SWD flies found in the summer. These WM were found ...

Systems To Attract And Feed Pollinators In Warm-Season Lawns, Michelle Wisdom

Theses and Dissertations

Pollinating insects are responsible for the production of many agricultural crops and they require floral resources to fulfill their life-cycle. Ideally, pollinating insects will encounter a diversity of floral resources across their entire season of activity, and those floral resources can include both herbaceous and woody plant species. Managed turfgrass areas have been identified as potential locations for creating pollinator-friendly habitats. In the transition zone, where both warm- and cool-season turfgrass species are present, the persistence of herbaceous plants in warm-season turfgrasses such as bermudagrass (Cynodon spp.) and buffalograss (Buchloe dactyloides), may be affected not only by the competitive nature ...

Diversity and Abundance of Invasive Aedes albopictus, Other Mosquitoes (Diptera: Culicidae), and Arthropods in North Georgia.

Carlisle M., Embrick M., Lampert E., Sangweme D.

With the increase in invasive species and the increasing numbers of the invasive Culicidae family member Aedes albopictus and the numerous deadly diseases Aedes albopictus can vector, it becomes increasingly important to survey and keep records of local populations and diversity of mosquitoes. We surveyed local culicid populations dissecting the female mosquitoes looking for nematodes to search for Wolbachia, and preserving all the bycatch and using the bycatch as an insight into the population and diversity ...

22 - Bugs In Bugs, Josemaria Garcia

Georgia Undergraduate Research Conference (GURC)

The primary purpose of the Bugs in Bugs project is to measure a student’s ability to go complete a research report and to observe demonstrations of key fundamental research aspects such as understanding scientific works, collecting and entering data, analyzing and creating graphs, and overall how to write a lab report. Working with Principles of Biology II and Microbiology classes, students were provided with a topic and methodology respective to their class; however, groups within the classes had the freedom to create their own hypotheses and theses, choose how to collect and interpret data, make charts and graphs, and ...

Effects Of Coumaphos And Imidacloprid On Honey Bee (Hymenoptera: Apidae) Lifespan And Antioxidant Gene Regulations In Laboratory Experiments, Ales Gregorc, Mohamed Alburaki, Nicholas Rinderer, Blair Sampson, Patricia R. Knight, Shahid Karim, John Adamczyk

Faculty Publications

The main objective of this study was to test comparatively the effects of two common insecticides on honey bee Apis mellifera worker’s lifespan, food consumption, mortality, and expression of antioxidant genes. Newly emerged worker bees were exposed to organophosphate insecticide coumaphos, a neonicotinoid imidacloprid, and their mixtures. Toxicity tests were conducted along with bee midgut immunohistological TUNEL analyses. RT-qPCR assessed the regulation of 10 bee antioxidant genes linked to pesticide toxicity. We tested coumaphos at 92,600 ppb concentration, in combination with 5 and 20 ppb imidacloprid. Coumaphos induced significantly higher bee mortality, which was associated with down regulation ...

Ecological Stoichiometry: What Role Does It Play In The Competition And Spatial Distribution Patterns Of Aedes Albopictus And Aedes Aegypti?, James Deerman

Master's Theses

Ecological stoichiometry is the balance of chemical substances within animal bodies through interactions and processes within their ecosystem. Though relatively underexplored, it provides a wealth of information linking interactions across different levels of organization. Detritus is the base of the food web within the small aquatic ecosystems occupied by the mosquitoes Aedes albopictus and Aedes aegypti. Nutrient content of detritus varies, but it can have a negative effect on mosquito growth and survival if nutrient thresholds are not met. I investigated nutrient environments and species abundance in cemetery vases in New Orleans, LA to assess detrital heterogeneity and its effect ...

Identification Of Microbiota Associated With The Ectosymbiotic Community Structure Of The Appalachian Brook Crayfish (Cambarus Bartonii), Matthew M. Cooke 6268927, Luke T. Fischer, Taylor Griffin, Sherrie Jeffers

Montview Liberty University Journal of Undergraduate Research

Microbes play a significant role in ecosystems, effecting the vital functions of other organisms, interspecies relationships, and population sizes. Based upon previous research (Skelton et al., 2016), it has been hypothesized that crayfish symbionts (branchiobdellidans) play a significant role in regulating the amount of microbiota associated with the host. A growing body of knowledge is known regarding both the condition of gill fouling and the annelid worm’s symbiotic relationship with the crayfish (Skelton et al., 2016; Skelton et al., 2016). However, there is little to no evidence available concerning the bacteria’s role in the process (Skelton et al ...

Acarine Biodiversity In Ecuador: Two New Species Of Endoparasitic Chiggers (Acarina: Trombiculidae) From Terrestrial Andean Anurans, Ricardo Guerrero, Mario Humberto Yánez-Muñoz

MANTER: Journal of Parasite Biodiversity

Two species of endoparasitic chiggers, Vercammenia neotropica n. sp. and Microtrombicula ecuadorensis n. sp., are described, both found in terrestrial anurans of the genus Pristimantis collected in the Andes of Ecuador. A new combination is proposed for Trombicula yorkei Sambon, 1928 as Microtrombicula yorkei (Sambon, 1928) n. comb., and Schoengastia lynni Ewing, 1942 is placed as incertae sedis. This is the first record of species of the genus Vercammenia in the Neotropical region.

Mechanisms Underlying Freeze Tolerance In The Spring Field Cricket, Gryllus Veletis, Jantina Toxopeus

Electronic Thesis and Dissertation Repository

Freeze tolerance has evolved repeatedly across insects, facilitating survival in low temperature environments. Internal ice formation poses several challenges, but the mechanisms that mitigate these challenges in freeze-tolerant insects are not well understood. To better understand how insects survive freezing, I describe a novel laboratory model, the spring field cricket Gryllus veletis (Orthoptera: Gryllidae). Following acclimation to six weeks of decreasing temperature and photoperiod (mimicking autumn), G. veletis juveniles becomes moderately freeze-tolerant, surviving freezing at -8 °C for up to one week, and surviving temperatures as low as -12 °C. Acclimation is associated with increased control of the temperature and ...

Wild, Native Bees And Managed Honey Bees Benefit From Similar Agricultural Land Uses, Elaine Evans, Matthew Smart, Dan Cariveau, Marla Spivak

Faculty Publications: Department of Entomology

Although both managed and unmanaged bees are important pollinators of crops and wild plants, efforts to address questions about landscapes that best support pollinators often focus on either wild pollinators or honey bees. This study examined if there was concordance between the success of wild bee communities and managed honey bee colonies at sites varying in floral availability and disturbance level in a predominantly agricultural landscape. We also determined which agricultural land uses best supported wild bee communities. The study area in the state of North Dakota in Northern Great Plains in North America is home to understudied native bee ...

Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese

Honors Scholar Theses

The Chrysoperla carnea-group of green lacewings is a cryptic species complex. Species within the group are morphologically similar, yet isolated from one another via reproductive mating song. Chrysoperla zastrowi, a species within the carnea-group, is currently described with a distribution ranging from South Africa to the Middle East and India. However, recent collections of carnea-group lacewings from Guatemala and California were preliminarily identified as Chrysoperla zastrowi based upon similarities in their vibrational courtship songs. This analysis aims to place six specimens, collected by collaborators in Guatemala, Armenia, Iran, and California, into a pre-existing phylogeny of the Chrysoperla ...

Biology Faculty Publications

A new Rhus gall aphid species Nurudea zhengii Ren, sp. nov. collected from the Mountain Qixing in Shangrao County, Jiangxi Province, China is described and illustrated from alate viviparous female. The new species differs from the other Nurudea species in the length and proportion of antennal segments, the structure of antennal secondary sensilla, and the flower-like shape of the galls that are formed on its primary host. Its primary host plant is Rhus hypoleuca, whereas other Nurudea species are on R. chinensis.

The Effects Of Juvenile Exposure To Sub-Lethal Concentrations Of Pesticides On The Adult Reproductive Biology Of The Male Southern House Mosquitoe, Culex Quinquefasciatus, Shiloh Dean Judd

LSU Master's Theses

Mosquitoes transmit pathogens capable of causing significant diseases, the worst of which can permanently disfigure or kill. Mosquito control efforts can be strengthened by better understanding all aspects of mosquito biology, but there is deficient information regarding sperm production in male mosquitoes. Understanding the sperm production and capacity of vector species may reveal new control strategies.

The goal of this research was to determine if larval exposure to sub-lethal concentrations, defined as killing less than half of the sample population, of pesticides negatively impacts the adult male reproductive health of the southern house mosquito, Culex quinquefasciatus Say. This study quantified ...

Novel Prey Record For Scymnus Caudalis Leconte And First Records Of Four Other Species Of Coccinellidae (Coleoptera) In Wisconsin, U.S.A., Louis S. Hesler, Jedidiah Nixon

The Great Lakes Entomologist

New prey and distribution records are presented for five species of lady beetles (Coleoptera: Coccinellidae). Scymnus (Pullus) caudalis LeConte is recorded for the first time preying on Aphis asclepiadis Fitch (Hemiptera: Aphididae). Four other lady beetle species are newly recorded in the state of Wisconsin, U.S.A: Diomus amabilis (LeConte), Diomus terminatus Say, Scymnus (Pullus) uncus Wingo, and Hyperaspidius wolcotti (Nunenmacher). The new state records represent minor to moderate extensions of previously known geographic distributions for these species. In addition, the records emphasize the importance of processing uncurated zoological specimens to provide information about the prey of particular species ...
