Single Night Surveys Of Moth Communities Can Serve As Ultra-Rapid Biodiversity Assessments, Daniel P. Duran, Matthew Timar, Blaine Rothauser

School of Earth & Environment Faculty Scholarship

Biodiversity conservation decisions are typically based on limited data and resources. For this reason, there is great interest in surveying taxa that may allow for a rapid assessment of the biodiversity at a site. Numerous taxa have been proposed and utilized for rapid assessments that allow for such a survey in a matter of weeks or less. Herein, we test the idea that nocturnal moths have many of the characteristics that make them ideal for such surveys, such as relative ease of identification, strong ecological association with specific plant species and habitats, high alpha diversity, extended seasonal activity, and ease …

Wild Bee Utilization Of Engineered Pollinator Habitat In Eastern Nebraska Agroecosystems, Shianne Lindsay

Dissertations and Student Research in Entomology

Habitat loss is a leading cause of biodiversity decline globally. Further, loss of natural and semi-natural habitat is a major factor contributing to declines in wild pollinator populations. Among intensive agroecosystems in the Midwestern United States, corn, soy, and small grain fields dominate the landscape and leave limited space available for forb-rich habitat that supports diverse pollinator assemblages to exist and thrive. There are numerous barriers and challenges to integrating pollinator habitat into such agroecosystems and quantitative assessments of impacts on pollinator communities are largely lacking. The establishment of high-quality pollinator habitat can provide both high flower abundance and species …

Examining Potential Trade-Offs Between Pest Management And Pollination To Sunflower Production In Nebraska, Luis Ochoa Cadena

Dissertations and Student Research in Entomology

Sunflower (Helianthus annuus) is cultivated for oil and seed production worldwide, and the United States produces 2.5% of the world’s oilseed sunflower primarily grown in the Great Plains. In 2022, oilseed and confectionary U.S. sunflower production increased by 48 and 44%, respectively, compared to last year's records. However, sunflower production can be seriously compromised by insect pests. The red sunflower seed weevil (Smicronyx fulvus LeConte) is considered the most serious pests in North America and causes severe economic damage yearly. On the other hand, native bees contribute substantially to sunflower yield. Currently, insecticide applications are the primary tool to suppress …

Effect Of Decreased Snowfall During An Atypical Winter On A Rare Butterfly’S Host Plant, Breelyn Gilbert

Biology Student Scholarship

In the Northeastern US, one result of climate change is decreased snowfall and earlier snowmelt. Such changes can alter the relationship between climate and the timing of cyclical biological phenomena— the phenology of organisms. This is especially concerning for species that interact with one another such as butterflies and their host plants. For this study, I focused on the host plant of the rare frosted elfin butterfly. The frosted elfin is a species of concern in RI, MA, and CT, among 8 other states, and they are a host plant specialist only laying eggs on yellow wild indigo (Baptisia …

Suitability And Nutritional Analysis Of Spotted Lanternfly Habitats, Kathryn Hickey

Biology Student Scholarship

The spotted lanternfly is an invasive bug that has recently started taking over the Northeastern US, and has even made it to Rhode Island. Although this species is intriguing with its bright red back and spots, it is hurting native plant species and the agriculture industry by feeding on crops, like grapes and cherries. It uses a tongue-like mouthpart to pierce through the plant and feed directly on the sap inside. This punctures plant stems and causes them to drip sap, wither, and even mold. The lanternfly’s most preferred host plant is the invasive tree-of-heaven, which grows and spreads quickly …

The Effect Of Integrated Pest Management On Honey Bee Behavior And Colony Level Health, Kaitlyn Bresnahan

Biology Student Scholarship

Honey bees are the world’s most commercially valuable pollinators, and they face many threats. The greatest challenge facing honey bees is Varroa mites, which are parasitic mites that feed on bees’ fat bodies, killing bees and spreading diseases. While chemical treatments are available to stop the spread of mites, these treatments are insecticides, which are not ideal to put in a hive of insects. A popular organic method of mite management is using drone comb. Drone brood is preferentially chosen by mites for ovipositing and development because of its larger size and longer development time, so removing drone brood can …

Diversity Of Bees In Trees And Their Foraging Preferences On An Urban College Campus, Aidan Castricone

Biology Student Scholarship

Pollinators collect nutrients from blooming flowers; pollen provides proteins and fats, nectar provides carbohydrates. The few plants that bloom during early Spring are trees such as crabapple (Malus sp). Current research however, mainly focuses on pollinators that forage on the ground and overlooks pollinators foraging in the canopy of trees. Past research showed increased generalization of pollen foraging in bees as seasons move from spring to summer. Here I identified which bee species forage in the canopy on Providence College campus and will analyze the pollen collected using microscopy. This data can inform more specific research on diet breadth, …

Insecta Mundi

Bicellonycha amoena (Gorham, 1880) (Coleoptera: Lampyridae) usually flies one meter above ground level over grass, water, or open areas, where males produce a simple single flash every 2–4 seconds, having their most active flashing period from mid to late dusk and early night. In addition, nothing else is known about the behavior of this species. We conducted field observations at the “Mayan Golf Club” in Guatemala Department, and Santiago Sacatepéquez, Sacatepéquez Department, Guatemala; and analyzed B. amoena flashes with a spectroscope. Fireflies displayed a lime-green bioluminescence color. The male flash­ing activity began ~30 minutes after sunset and lasted approximately 70 …
