Grass Weed Control And Rice Response With Tetflupyrolimet-Containing Programs, Mason C. Castner, Jason K. Norsworthy, Thomas R. Butts, Trenton L. Roberts, Nick R. Bateman, Travis R. Faske

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Tetflupyrolimet is the first herbicide with a novel site of action (SOA) labeled PRE and early POST for use in agronomic crops to be labeled in the last three decades. Direct-seeded paddy rice field experiments were conducted near Stuttgart, AR, on a silt loam soil and near Keiser, AR, on a clay soil to evaluate tetflupyrolimet-containing herbicide programs in comparison to commercial standards in conventional, imidazolinone-resistant, and quizalofop-resistant rice systems. Additionally, a furrow-irrigated rice experiment was conducted near Colt, AR, and Keiser to ensure weed control with clomazone and tetflupyrolimet mixtures compared to commercial standards. Twelve commonly planted rice cultivars …

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionally, studies often focus on taxonomic diversity, while other important biodiversity components, including phylogenetic diversity, can exhibit differential responses. Here, we evaluated how agricultural and urban land use alters the taxonomic and phylogenetic α-, β-, and γ-diversity of an important pollinator taxon-bees. Using a multicontinental dataset of 3117 bee …

A Phylogeographic Study Of The Kentucky Endemic Cave Beetle Neaphaenops Tellkampfii Erichson (1844), Mahamad Miya

Masters Theses & Specialist Projects

Cave beetles are an excellent group to study evolutionary history and speciation by isolation within cave habitats. However, they are underrepresented in such studies, particularly in North America, one of the hotspots of cave biodiversity where beetles account for a significant proportion. The present research addresses this issue by focusing on the Kentucky endemic cave beetle, Neaphaenops tellkampfii, a species hypothesized to comprise four subspecies. Based on allozyme data, previous studies have noted high genetic variation within and high similarity among local populations of this beetle, suggesting complex evolutionary dynamics. In this regard, this study aims to elucidate the evolutionary …

A Systematic Study Of The Highly Endemic Spider Beetle Fauna (Coleoptera: Ptinidae: Ptininae) Found In The Coastal Deserts Of Perú, Marlena Askren

Masters Theses & Specialist Projects

Spider beetles are small, often flightless insects that occur in hyperarid environments around the world. They exhibit interesting morphology and behavior that allows them to conserve water they obtain from plant material, dung, and other detritus. One hyperarid region in which they are found is the Pacific coast of Perú and northern Chile. The Sechura Desert, Peruvian Coastal Desert, and Atacama Desert make up the arid coast where spider beetles occur from north to south. Through multiple years of field work and museum collections, populations of spider beetles were found along the coast in isolated pockets of vegetation, separated by …

Diversity And Phylogeny Of Spider Beetles (Ptinidae: Ptininae) In Coastal Chile And Peru, Jacob Bowen

Masters Theses & Specialist Projects

Spider beetles of South America have historically received little systematic study, though now they are the subject of recent diversity surveys and documentation. This investigation contributes to the ongoing exploration of spider beetle diversity in South America by adding records for the recently described Cordielytrum and the yet to be described Furcillifer, as well as constructing phylogenies with new genetic material. MaxEnt was used to create an ecological niche model revealing habitat suitability in Chile and Peru for Cordielytrum, a genus of flightless spider beetles currently known only from Peru. Even with few occurrence records, a model with …

Learning In Nonleafcutting Fungus-Gardening Ants, Elizabeth D. Boshers

Biology Theses

Social complexity influences learning and other cognitive behaviors, but for insects, this influence is not well understood. Delayed rejection is an aversive learning behavior previously studied exclusively in leafcutting ant species, the most socially complex of the fungus-gardening ants. Fungus-gardening ants are unique in that they do not directly consume the material they forage, using it instead as substrate to cultivate a symbiotic fungus on which the ants are obligately dependent. Here, I attempt to induce delayed rejection in several fungus-gardening ant species that exhibit a range of social complexity, then compare the characteristics of delayed rejection behavior among species. …

Assessing The Foraging Habits Of Two Species Of Long-Horned Bees (Melissodes, Apidae) Using Dna Barcodes Its2 And Trnl, Rebecca Jane Foy

Theses, Dissertations and Capstones

Sunflowers (Helianthus, Asteraceae) are an important crop used for oil, dye, fodder, and edible seeds. Long-horned bees (Melissodes, Apidae) are solitary species native to the Americas that specialize in sunflower pollination; they are among the most frequent visitors to sunflowers, and have been shown to enhance yield, offering considerable economic benefits to sunflower production. This study used metabarcoding to investigate the foraging habits of two understudied Melissodes species, M. trinodis and M. agilis. Using the ITS2 and trnL barcodes, our study aimed to (1) investigate the plants visited by M. agilis and M. trinodis and (2) assess the distances Melissodes …

Diet Of Adult Ladybird Beetle Hosts Modifies The Postdiapause Development Of The Parasitoid Dinocampus Coccinellae (Hymenoptera: Braconidae), John J. Obrycki

Lady Beetle Research Data

Our study showed that under natural conditions the rate and speed of postdiapause emergence by overwintering larvae of the endoparasitic wasp, Dinocampus coccinellae (Schrank) is enhanced when its ladybird beetle host Coleomegilla maculata (DeGeer) receives a nutritious (proteinaceous) diet during late winter and early spring. Living aphid prey provided during April and May yielded the fastest rates of D. coccinellae postdiapause development, followed by an artificial protein/carbohydrate diet and flowering (pollen-producing) heads of dandelion. D. coccinellae development was slowest when hosts received only sugar water or water alone. These results indicate that there is an interaction during late dormancy between …

Developmental Regulation Of Corazonin, Eclosion Hormone, And Bursicon Messages And Rnai Suppression Of Corazonin In Adult Female American Dog Ticks, Dermacentor Variabilis, Anirudh Dhammi, Brooke Bissinger, Loganathan Ponnusamy, Daniel E. Sonenshine, R. Michael Roe

Biological Sciences Faculty Publications

The insect molting process is critical to growth and development and is regulated in part by the neuropeptides corazonin, eclosion hormone, and α and β bursicon. We found messages in a synganglion transcriptome from adult, female American dog ticks, Dermacentor variabilis (that do not molt), with a high similarity to the larval insect neuropeptides that control molting. The phylogenetic analysis of the tick putative neuropeptides compared to other arthropods is discussed in detail. The relative gene expression of these peptides was determined by quantitative PCR during the following adult developmental stages: (i) virgin, unfed 0–24 h after entering the adult …

Correction On The Status Of Nematodes Pavidus Horn, 1886 (Coleoptera: Eucnemidae: Dromaeolinae: Dromaeolini), With Redescriptions Of Two Species From The Southeastern United States And The Caribbean, Robert L. Otto

Insecta Mundi

The status of Nematodes pavidus Horn (Coleoptera: Eucnemidae), in relation to Nematodes punctatus LeConte and Nematodes teres Horn is being questioned after Muona (2000) revised the family in the Nearctic region. Investigations into the status of N. pavidus included explorations of the histories among these three species and examining images of the types through the Museum of Comparative Zoology’s website. It has been confirmed that Muona erred by synonymizing N. pavidus with N. teres before transferring both N. punctatus and N. teres to Dromaeolus Kiesenwetter. A correction has been made by transferring N. pavidus …

Three New Species Of Lepidocyrtus Bourlet (Collembola: Entomobryidae) From Florida, Usa, And Descriptive Notes On Lepidocyrtus Floridensis Snider, Felipe N. Soto-Adames, Emily Jenks, Kathryn M. Daly

Insecta Mundi

Abstract

In North America, the genus Lepidocyrtus Bourlet (Collembola: Entomobryidae) is represented by 18 species, but only three (L. floridensis Snider, L. millsi Snider, and L. pallidus Reuter) have been reported from Florida. We investigated species diversity in leaf litter samples from counties in the north-central and southern part of the state, as the reportedly low species diversity in Florida may be due to under-sampling. As a result, in this contribution we describe three species of Lepidocyrtus new to science: L. bobwoodruffi Soto-Adames, Jenks and Daly, new species, L. brambilae Soto-Adames, Jenks and …

Habitat Definition For Pepsis Elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae), Frank E. Kurczewski

Recent (2024) photographs of Pepsis elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae) females searching through plant litter disclosed no clues about its nesting behavior or host spider. However, coupled with geographic site locations, they reveal important habitat information. The various site locations are specifically defined as part of the Eastern Temperate Forests Level I Ecoregion of North America, numerous Level III Ecoregions of the Continental United States, several United States Forest Type Groups, and natural habitat designation of mesic open woodland.

A Taxonomic Note On Lecanium Vaccinii Macrocarpum Nomen Dubium Status, Rhys J. L. Campo, Barbara D. Denno, Douglass R. Miller

Insecta Mundi

Lecanium vaccinii macrocarpum Goethe, 1884 (Hemiptera: Coccidae) is a subspecies of which the original description is inconsistent with its current taxonomic placement, and its recorded synonymy with other species is questionable. The original type material is likely lost or destroyed. For these reasons, L. vaccinii macrocarpum is proposed to be treated as nomen dubium.

New Host Record Of Dahlibruchus Bridwell, 1931 On Cultivated Dahlia Cav. In Mexico And Description Of Two New Species (Coleoptera: Bruchidae), Jesús Romero Nápoles

Insecta Mundi

Dahlibruchus Bridwell is a genus in the family Bruchidae (Coleoptera: Chrysomeloidea) and all species have as host plants species in the genus Dahlia Cav. (Asteraceae). Usually they arrive on hosts when flowers appear and start feeding on nectar and pollen; later females lay eggs on bracts, and a few weeks later the adults emerge. Presently, the genus Dahlibruchus contains three species. The description of two new ones (Dahlibruchus castroi, new species and Dahlibruchus ruizi, new species) brings this number to five. A key to all species is presented. Dahlibruchus conradti Bridwell is recorded for the first …
