The Trichoplusia Ni Gut Microbiome And Its Derivation From The Phyllosphere Of Its Food Plants, Josemaria Garcia, Marisol Escanuela, Swapna Bhat, Evan Lampert

Georgia Journal of Science

Insects are the most abundant and diverse animals on planet Earth and rely on their diverse microbiomes to be so. The insect gut microbiome is vital in the growth and development of many insect species. Trichoplusia ni, the cabbage looper, is a generalist herbivore, but little is known about its microbiome. In this study, a metagenomic analysis of fecal samples was used to determine the effect of diet on the microbiome of T. ni larvae. Larvae were reared on six plant species, the microbiome was sampled from fecal material, and the phyllosphere was sampled from leaves the larvae ate. Bacteria ...


Splitting The Hive, Sheriden M. Hansen, Andree Walker-Bravo, Jaydee Gunnell 2020 Utah State University

Splitting The Hive, Sheriden M. Hansen, Andree Walker-Bravo, Jaydee Gunnell

All Current Publications

Warming late spring temperatures mark the beginning of swarm season in Utah, especially for beehives that have successfully overwintered. Swarming is when bees naturally divide the existing colony roughly in half, with half the bees remaining in the hive and the other half leaving (with the queen) to look for new accommodations. Colonies that swarm are often left with limited resources, do not produce much honey, and can be rendered too weak to overwinter. Splitting your hives in anticipation of swarming can help reduce the negative effects of swarming, giving bees a chance to build up resources and strength before ...

Entomology Publications

The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) is a serious pest of the soybean plant, Glycine max, a major world-wide agricultural crop. We assembled a de novo genome sequence of Ap. glycines Biotype 1, from a culture established shortly after this species invaded North America. 20.4% of the Ap. glycines proteome is duplicated. These in-paralogs are enriched with Gene Ontology (GO) categories mostly related to apoptosis, a possible adaptation to plant chemistry and other environmental stressors. Approximately one-third of these genes show parallel duplication in other aphids. But Ap. gossypii, its closest related species, has the lowest number ...


Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein 2020 University of Nebraska-Lincoln

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 ...

Herbicide Effects On The Feeding Behavior Of The Wolf Spider Pardosa Milvina, Briana Heinly, William Ward, Catherine Johnson, Jack Preston

Senior Scholars Day

Herbicides can potentially impact feeding behavior of beneficial predators in agricultural systems and subsequently compromise integrated pest management efficacy. We measured variation in feeding behaviors of an agriculturally abundant wolf spider, Pardosa milvina, when exposed to soil with field-relevant concentrations of five commonly used herbicides. Tested herbicides included atrazine, S-metolachlor, rimsulfuron, mesotrione, glyphosate, a mixture of all five herbicides, and a distilled water control. Spiders were housed individually in containers with topsoil previously sprayed with a recommended herbicide dosage or water control. Tested spiders were collected from two adjacent fields: one kept under continuous crop rotation for over twenty years ...

Insecta Mundi

Abstract. In 2017, a new project was begun to assess the biodiversity of national parks and forest reserves in the Republic of Panama. Designated “Proyecto Sistema de Producción Sostenible Conservación de la Biodiversidad (PSPSCB)”, this project is managed by Panama’s Ministerio de Ambiente. The first park sampled in 2017 was Omar Torrijos Herrera National Park (OTHNP). Trichoptera (Insecta) were collected at four locations using both Malaise traps and UV light traps. The rugged terrain and lack of access in this remote park limited the sampled area. Sampling included streams in both the Caribbean and Pacific drainages. Seven new species ...

Effects Of Pesticide Residue Accumulation On Honey Bee (Apis Mellifera L.) Development & Implications For Hive Management, Jennifer Weisbrod 2020 University of Nebraska - Lincoln

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

Dissertations and Student Research in Entomology

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 ...
