New Species, A New Combination, And A New Country Record In American Clytini (Coleoptera: Cerambycidae: Cerambycinae), Juan Pablo Botero, Antonio Santos-Silva, James E. Wappes

Insecta Mundi

Two new species of Mexican Clytini (Coleoptera: Cerambycidae: Cerambycinae) are described: Trichoxys giesberti Botero, Santos-Silva and Wappes (also added to a recent key) and Megacyllene giesberti Botero, Santos-Silva and Wappes. The geographical distribution of Megacyllene melanaspis (Chevrolat, 1862) is expanded to include Bolivia, new country record, and compared to the similar and sympatric Megacyllene proxima (Laporte and Gory, 1841); Megacyllene asteca (Chevrolat, 1860) is proposed as a new combination for the previous Plagionotus asteca, and Amyipunga armaticollis (Zajciw, 1964) is redescribed to correct previous errors regarding it in the literature. Additionally, characters to help separate it from the similar …

Korean Encyrtids (Hymenoptera: Encyrtidae) Associated With Scale Insects (Hemiptera: Coccomorpha), Soo-Jung Suh

Insecta Mundi

Scale insects (Hemiptera: Coccomorpha) are sap-sucking plant parasites and economically important pests on agricultural and horticultural crops. Scale insects are often difficult to control since their body is protected by a wax cover. Parasitic wasps that live and develop in scale insects are important natural enemies and effective biological control agents of pest scale insects. Chalcid wasps of the family Encyrtidae (Hymenoptera: Chalcidoidea) comprise the largest group of parasitoids of scale insects, followed by the family Aphelinidae. Here, an updated list of all thirty-six species of encyrtids in twenty-three genera that have been identified or reported from South Korea is …

Observations On The Natural History Of Romulus Globosus Knull (Coleoptera: Cerambycidae), Josef Vlasak

Insecta Mundi

Host plants of Romulus globosus Knull (Coleoptera: Cerambycidae) are described for the first time. Notes on its natural history are provided. The larvae of R. globosus feed in living roots of scrub oaks, including Quercus geminata Small, Quercus myrtifolia Willd., and Quercus laevis Walter. Field observations show that the beetle emerges below ground, and females may burrow to lay eggs on the roots.

Effects Of Diet Quality And Temperature On Stable Fly (Diptera: Muscidae) Development, Melina Florez-Cuadros, Dennis Berkebile, Gary Brewer

Department of Entomology: Faculty Publications

The effects of diet quality and temperature on the development time and size of stable flies, Stomoxys calcitrans (L.), was evaluated. Both development time and size varied relative to diet quality and temperature, and their effects were additive. Diet quality and temperature made similar contributions to the variance in size whereas temperature was responsible for >97% of the variance in development time. Regression analysis predicted the shortest development time, egg to adult, to be 12.7 days at 32 ^◦C and 70% nutrients. Egg to adult development varied curvilinearly relative to diet quality and temperature on the degree day 10 …

Nutritional Status Of Honey Bee (Apis Mellifera L.) Workers Across An Agricultural Land-Use Gradient, Matthew D. Smart, Clint R. V. Otto, Jonathan G. Lundgren

Department of Entomology: Faculty Publications

Land use, habitat, and forage quality have emerged as critical factors influencing the health, productivity, and survival of honey bee colonies. However, characterization of the mechanistic relationship between differential land-use conditions and ultimate outcomes for honey bee colonies has been elusive. We assessed the physiological health of individual worker honey bees in colonies stationed across a gradient of agricultural land use to ask whether indicators of nutritional physiology including glycogen, total sugar, lipids, and protein were associated with land-use conditions over the growing season and colony population size the subsequent spring during almond pollination. Across the observed land-use gradient, we …

Colony Breeding Structure Of Reticulitermes (Isoptera: Rhinotermitidae) In Northwest Arkansas, Allen Szalanski

Entomology and Plant Pathology Faculty Publications and Presentations

Termites, as social insects, have a complicated life cycle in which the colony breeding structure, that is the number of and origin of reproductives in a colony, can vary in relation to age and environmental factors. In this study, we used genetic methods to characterize the breeding structure of three species of Reticulitermes from three sites in northwest Arkansas and compared two habitats: undeveloped, forested sites and developed, agricultural sites. We found 57.1% of R. flavipes (Kollar) in northwest Arkansas (n = 28) were simple families, 39.3% were extended families and 3.6% were mixed families. Similarly, for R. hageni Banks …

Notes On The Natural History Of Selected Invertebrates From Arkansas, 2019, Matthew B. Connior, Renn Tumlison, Henry Robison

Journal of the Arkansas Academy of Science

The invertebrate fauna are a large component of ecosystem. Yet, invertebrate biologists are few and scattered in Arkansas; thus, the invertebrate fauna of much of the state is poorly known. Herein we document new records of distribution and provide notes on the natural history of selected invertebrates from Arkansas. Of note, we provide records on planarians, crayfish, centipedes, and spiders.

Maximizing Ecosystem Services Provided To The New Oil Crop Brassica Carinata Through Landscape And Arthropod Diversity, Shane Stiles

Electronic Theses and Dissertations

Prairies, once spanning the Upper Midwest, have now largely been replaced by agriculture. The lack of resources available to pollinators in agricultural fields and the practices employed by farmers to maximize yield has led to a decline in insect and pollinator diversity. There is a need to better understand how ecosystem services provided by a diverse insect community scale to current farming practices as they relate to crop yield. We sought to explain how landscape heterogeneity relates to insect and pollinator diversity, as well as how insect diversity relates to crop yield across common farming practices. To evaluate how farming …

The Impact Of Prescribed Fire On Moth Assemblages In The Boston Mountains And Ozark Highlands, In Arkansas, Erin E. Guerra, Cristina M. Blanco, Jorista Garrie

Journal of the Arkansas Academy of Science

In addition to the impacts of prescribed fires on forest vegetation, this ecosystem process also has dramatic impacts on associated insect assemblages. For herbivorous, terrestrial insects, fire predictably results in a cycle of initial insect population reduction followed by recovery and growth, in which these insect populations exceed pre-fire abundances. We sought to examine if fire-induced disturbance cycles make prescribed burned areas more or less suitable specifically for moths (order Lepidoptera), which is a major food source for, among others, multiple bat species. We surveyed moth assemblages at 20 burned and 20 unburned sites in the Boston Mountain and Ozark …

Haplotype Diversity And Population Genetic Structure Of Antistrophus Gall Wasps Associated With Two Silphium Species And Implication For Host Mediated Speciation, Jiaxin Deng

Masters Theses

Gall making insects form a special feeding guild of phytophagous animals, and by manipulating host plant tissue differentiation, are able to avoid plant chemical defenses and thus have no need for counter defense mechanisms. Host plant selection is crucial to the evolution of these insects because successful gall formation is largely dependent on host plant ability to respond to stimuli. In Illinois and neighboring states, Antistrophus gall wasps associated with the rosin weed (S. integrifolium) and the cup plant (S. perfoliatum) are morphologically indistinguishable and thus have been treated as belonging to single species. However, the wasps from the host …

Bifenthrin Baseline Susceptibility And Evaluation Of Simulated Aerial Applications In Striacosta Albicosta (Lepidoptera: Noctuidae), Débora G. Montezano, Thomas E. Hunt, Dariane Souza, Bruno C. Vieira, Ana M. Velez, Greg Kruger, Sarah N. Zukoff, Jeff D. Bradshaw, Julie A. Peterson

Department of Entomology: Faculty Publications

Striacosta albicosta (Smith) is a maize pest that has recently expanded its geographical range into the eastern United States and southeastern Canada. Aerial application of pyrethroids, such as bifenthrin, has been a major practice adopted to manage this pest. Reports of field failure of pyrethroids have increased since 2013. Striacosta albicosta populations were collected in 2016 and 2017 from maize fields in Nebraska, Kansas, and Canada and screened with bifenthrin active ingredient in larval contact dose-response bioassays. Resistance ratios estimated were generally low in 2016 (1.04- to 1.32-fold) with the highest LC50 in North Platte, NE (66.10 ng/cm²) …

The Effect Of Anthropogenic Environmental Modifications On Malaria Vectors In Amazonian Peru And Brazil, Catharine Prussing

Legacy Theses & Dissertations (2009 - 2024)

Malaria is the most deadly vector borne disease, causing substantial morbidity and hundreds of thousands of deaths worldwide each year. In the Americas, the incidence of malaria has increased steadily since 2014. The factors driving continued malaria transmission are complex and highly variable across endemic areas. These factors include inadequate access and financial commitment to prevention, diagnosis, and treatment, and a failure to target interventions to heterogeneous malaria transmission patterns and vector populations. Nyssorhynchus darlingi (formerly Anopheles darlingi), the predominant malaria vector in Latin America, is known for behavioral, phenotypic, and genetic variability across its range, which allow it to …

Vector Tick Transmission Model Of Spotted Fever Rickettsiosis, Tais Berelli Saito, Jeremy Bechelli, Claire Smalley, Shahid Karim, David H. Walker

Faculty Publications

Many aspects of rickettsial infections have been characterized, including pathogenic and immune pathways and mechanisms of rickettsial survival within the vertebrate host and tick vector. However, very few studies are focused on the complex pathogen–vector–host interactions during tick feeding. Therefore, our objective was to develop a tick transmission model of the spotted fever group of rickettsial infections to study the initial events in disease development. The most appropriate strain of mouse was identified for evaluation as a transmission model, and the course of infection, bacterial levels, histopathologic changes, and antibody response during tick transmission in mice infested with Amblyomma maculatum …

An Army Of One: Predaceous Diving Beetle Life History Stages Affect Interactions With Shared Mosquito Prey, Carmen E. Bofill, Donald A. Yee

Faculty Publications

Predators with complex life cycles often differ in their morphology, behavior, and trophic position across their ontogeny, and may thus have variable effects on shared prey. We used the predaceous diving beetle Laccophilus fasciatus rufus as our predator, whose larvae and adults often co-occur in freshwater lentic systems. As a shared prey we used early and late instar Culex quinquefasciatus, a common wetland mosquito. We found that single adult predators were more likely to consume late instar prey compared to juvenile predators, who ate early and late instar prey equally. A mixture of juvenile and adult predator stages led …
