Stream Restoration Effectiveness In Mullins Creek In Fayetteville, Arkansas, Amadeo Scott, Shannon Speir

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

Evaluating Efficiency And Accuracy Of Three Texture Analysis Methods For Blackberry Fruit, Rhys M. Brock, Carmen Johns, Katelyn Lust-Moore, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A major objective of the University of Arkansas System Division of Agriculture (UADA) Fruit Breeding program is to improve the texture of blackberry (Rubus subgenus Rubus Watson). Blackberry varieties with improved fruit firmness transport and store well and may maintain superior quality under challenging postharvest conditions than softer varieties. Increased firmness may also make cultivars less susceptible to red drupelet reversion (RDR), a postharvest disorder of blackberries in which fully black drupelets revert to red after harvest. This research project aims to assess the efficiency and accuracy of three methods applied in evaluating blackberry firmness. The study compares instrumental analysis …

Two New Species Of Bumblebee Scarabs (Coleoptera: Glaphyridae: Lichnanthe Burmeister) From The Central United States: A New Discovery In Wyoming Resolves A Century-Old Puzzle From The Nebraska Sand Hills, Matthew J. Paulsen

Insecta Mundi

The genus Lichnanthe Burmeister (Coleoptera: Scarabaeoidea: Glaphyridae) has comprised eight Nearctic species and contains the only New World members of their family. Here, two new species of arenicolous bumblebee scarabs are described from the central United States. The recent discovery of an undescribed Wyoming species led to the reevaluation of a dubious 134-year-old Nebraska Lichnanthe specimen, indicating that it also was an undescribed species. These two species, Lichnanthe brusti new species from central Wyoming and L. bruneri new species from central Nebraska are immediately distinguishable from all existing species of the genus by their square mandibles.

New Synonym Of Attagenus Tigrinus (Fabricius, 1792) (Coleoptera: Dermestidae: Attageninae), Graham J. Holloway, Andreas Herrmann

Insecta Mundi

The Attagenus bifasciatus species complex (Coleoptera: Dermestidae: Attageninae) surrounds the Mediterranean and extends into Asia. Several species are recognised but all of them are very similar to each other, and brief, old descriptions do not help to distinguish among them. Here the holotype A. tigrinus (Fabricius) and a syntype series of A. bifasciatus rossii Ganglbauer (subsequently raised to A. rossii) all collected from Italy were dissected to facilitate genital examination. From this genitalic study, Attagenus rossii is placed as a new synonym of A. tigrinus.

Aporus (Aporus) Niger (Cresson), A Reclusive Spider Wasp (Hymenoptera: Pompilidae: Pompilinae: Aporini) From Eastern North America, Frank E. Kurczewski

Insecta Mundi

There is no host or nesting information for Aporus (Aporus) niger (Cresson) (Hymenoptera: Pompilidae: Pompilinae: Aporini). Wasps in the tribe Aporini and, specifically, the genus Aporus Spinola capture only mygalomorph spiders (Araneae: Mygalomorphae). Purse-web spiders of the genus Sphodros Walckenaer (Araneae: Mygalomorphae: Atypidae) are the most likely host spiders of A. (A.) niger based on Aporus-Mygalomorphae parasitoid-host relationship, Aporus comparative morphology, geographic and habitat sympatry, seasonal synchrony, abundance, and retreat confinement. Aporus niger is the only aporine wasp in Wisconsin, lower Michigan, and southern Ontario. Sphodros niger is the only mygalomorph spider in Wisconsin, …

Calliphoridae Of Organ Pipe Cactus National Monument, Andrew Meeds

Department of Entomology: Distance Master of Science Projects

This project aimed to establish a baseline understanding of the blow fly fauna of Organ Pipe Cactus National Monument (OPCNM). Blow flies are the most commonly used insect in criminal investigations due to their tendency to be the earliest to locate and colonize remains. By understanding their distributions and patterns of seasonality, forensic entomologists can determine which species are most likely to colonize remains and identify which species may require further study. An 11-month comparison between fresh and aged chicken liver-baited traps improves understanding of primary and secondary colonizers in Organ Pipe Cactus National Monument and offers insights into effective …

Integrated Pest Management Of Maple (Acer) In Midwest Nursery Production, Darcey Hickey

Department of Entomology: Distance Master of Science Projects

Introduction

In all agricultural settings, damage from arthropod pests is inevitable. Integrated Pest Management (IPM) was introduced in the 1970’s as a response to increased public awareness of the hazardous effects of pesticides in the environment (Frazier, 2010). Ornamental nursery production is an important sector of US agriculture. In ornamental nurseries, pest damage is the leading cause of revenue loss (Braman et al., 2015). IPM has primarily been implemented for agricultural settings and as IPM is specific to each environment, it is important to explore the use of IPM practices in nursery production. As nurseries are found across the United …

Evolution Of The Largest Insect Orders: A Comprehensive Literature Review, Jason Thompson

Department of Entomology: Distance Master of Science Projects

Introduction

Insects are regarded by many to be among the most successful organisms on earth, displaying remarkable diversity, resilience, and adaptations, allowing them the ability to inhabit and exploit a wide array of niche environments. If sheer numbers are utilized as a yardstick by which to measure success, it has been estimated that there may be as many as 10 quintillion insects alive and active at any given time (Sabrosky, 1952). In terms of species diversity, estimates have ranged from as many as 30 million based on research and collections in tropical forest canopies (Erwin, 1982) to more recent, conservative …
