Exploring The Relationships Between South Texas Northern Bobwhite Populations And Cecal Worms Via System Dynamics, Nicole J. Traub, Benjamin L. Turner, Leonard A. Brennan, Alan M. Fedynich

National Quail Symposium Proceedings

Community ecology historically focused on plants and free-living organisms; however, problems such as defining habitat boundaries and obtaining adequate sample sizes arise when evaluating such communities. The unique nature of host-helminth systems allows parasite community ecologists to avoid these problems when testing ecological hypotheses. Unlike free-living communities that have artificially constructed boundaries, parasite communities have well-defined unambiguous boundaries within host individuals. Due to the inherently complex and dynamic nature of ecological systems, traditional experimental methods often require expensive, long-term trials beyond investigators’ time and resource budgets. Conversely, a system dynamics approach facilitates learning about such systems via simulation of ecosystem …

Subspecific Designation For The Central Appalachian Mountains Population Of Argynnis (Speyeria) Atlantis (W. H. Edwards), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The population of Argynnis atlantis of the central Appalachian Mountains, primarily on the Allegheny Plateau of West Virginia, has long been recognized by entomologists in the eastern United States as distinct from nominotypical populations of A. atlantis in the northeastern United States and eastern Canada. Larger size is often cited, but actual comparison of wing markings has not been done to date. This study applies RGB color analysis on a series of adults from both regions and looks at potential differences in wing markings which may distinguish them.

Erratum To Leblanc (2022): The Dacine Fruit Flies (Diptera: Tephritidae: Dacini) Of Oceania, Luc Leblanc

Insecta Mundi

After publication of Leblanc (2022), it was noticed that the wrong graph was used for the mean (±SE) daily captures of Dacus perpusillus (Drew) in cue-lure traps (Fig. 135). The author and the Insecta Mundi editorial staff apologize for this error. The intended version of Figure 135 is reproduced here. Insecta Mundi has also released a revised version of the Leblanc (2022) manuscript, with this error corrected. However, the revised version is not an official peer-reviewed article, and anyone wishing to reference the findings of Leblanc (2022) should cite the original manuscript or this erratum.

Different Gut Microbiomes Of Developmental Stages Of Field-Collected Native And Invasive Western Bean Cutworm, Striacosta Albicosta, In Western Nebraska, Paul A. Ayayee, Austin Currie, Julie A. Peterson

Department of Entomology: Faculty Publications

While insects harbor gut microbial associates that perform various functions for the host, lepidopterans have not been considered as prime examples of having such relationships. The western bean cutworm, Striacosta albicosta (Lepidoptera: Noctuidae), is native to North America and has historically been a significant corn pest in its western distribution. It is currently expanding eastwards and is invasive in these new regions. Using 16S rRNA gene sequencing data, this study focused on characterizing the microbiota associated with field-collected eggs, larvae, adults, and host plant materials of S. albicosta in its native range. The diversity of microbiomes varied significantly among S. …

Parasitisation Of Weaver Ants By A Species Of Smicromorpha Girault (Hymenoptera: Chalcididae: Smicromorphinae) And Unequivocal Evidence Of Its Presence In The Afrotropical Region, Robert S. Copeland, Bethelihem Mekonnen, Gerard Delvare

All Peer-Reviewed Publications

Smicromorpha Girault (Hymenoptera: Chalcididae) is distributed in the old world tropics and subtropics from Australia through New Guinea, Southeast and South Asia. Since its original description in 1913 conclusive evidence of its host has been lacking although it has been collected in association with weaver ants (Oecophylla spp.; Formicidae: Formicinae) either in proximity to ant nests or, on one occasion, reared from one. In this paper we report the presence of Smicromorpha pupae within the gaster of Oecophylla longinoda workers from a nest collected in coastal Kenya. This discovery extends the distribution of Smicromorpha to the Afrotropical Region and demonstrates …

Co-Transcriptomic Analysis Of The Maize–Western Corn Rootworm Interaction, Lise Pingault, Saumik Basu, Neetha N. Vellichirammal, William Paul Williams, Gautam Sarath, Joe Louis

Department of Entomology: Faculty Publications

The Western corn rootworm (WCR; Diabrotica virgifera virgifera) is an economically important belowground pest of maize. Belowground feeding by WCR is damaging because it weakens the roots system, diminishes nutrient uptake, and creates entry points for fungal and bacterial pathogens and increases lodging, all of which can significantly suppress maize yields. Previously, it was demonstrated that belowground herbivory can trigger plant defense responses in the roots and the shoots, thereby impacting intraplant communication. Although several aspects of maize-WCR interactions have been reported, co-transcriptomic remodeling in the plant and insect are yet to be explored. We used a maize genotype, …

Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates H. zea population dynamics are hierarchically structured with continental-level effects …

Integrated Pest And Pollinator Management, Ann Mull, Lori R. Spears, Marion Murray, Ricardo Ramirez

All Current Publications

An inextricable link exists between humans and pollinators, with benefits that include ecosystem health and function and human food security. Bees, butterflies, moths, wasps, flies, and beetles are responsible for most the world's pollination services. Considering the mounting scientific evidence denoting global pollinator declines, there is a critical need to prioritize pollinators and the essential services they provide. This fact sheet provides information about integrated pest and pollinator management (IPPM), which goes beyond integrated pest management (IPM) to include proactive, preventive measures that consider pollinators as well as pests in horticulture management.

A key, an annotated checklist with detailed distribution, biological and host information, and color photographic plates are provided for the 91 species of dacine fruit flies (Diptera: Tephritidae: Dacini) known to occur in Oceania. Dacus virgatus Coquillett, previously a synonym of Bactrocera psidii (Froggatt), is in­stead considered a junior synonym of B. facialis (Coquillett). The species originally described in 1971 as Dacus (Asiadacus) perpusillus Drew, later reassigned as Bactrocera (Sinodacus) perpusilla (Drew) and in re­cent years as Zeugodacus (Sinodacus) perpusillus (Drew) actually belongs to genus Dacus, and is transferred back to Dacus, …

Microbial Dimension Of Symbiosis And Dysbiosis In Fungus–Gardening Ants, Blake S. Bringhurst

Biology Theses

With symbiotic partners, the means by which a host obtain a symbiont influence the specificity between the host and the symbiont. One such system where symbiont specificity is seen to varying degrees is with higher attine ants. Higher attine ants have symbiotic relationships with the fungal cultivar they grow and the bacterial symbionts in their microbiomes. Among the higher attines, there are two broad groups of fungi. Most ants in the genus Trachymyrmex tend to grow Clade–B fungi, which are a group of undescribed Leucocoprinus species, while leaf–cutting ants in the genera Acromyrmex and Atta tend to grow Clade–A fungi …

Diversity Of Bees In Trees On An Urban College Campus, Aidan Castricone

Biology Student Scholarship

It is well known that insect pollinator populations are declining and a lack of nutrients (i.e flowering plants) may be a contributor to this decline. Insect pollinators forage for pollen and nectar, which provides proteins, fats, and carbohydrates, from flowering plants. Current research on pollinator foraging behavior focuses on pollinators that forage on the ground thus overlooking those that forage in trees. Trees such as Kousa dogwood (Cornus kousa) and crabapple (Malus sp.) bloom in early Spring, even before herbaceous perennials and forbs. Thus trees are likely the only places for early flying pollinators to find food. …

Assessment Of Population Size, Survival, And Movement Behavior Of The Rare Frosted Elfin Butterfly, Breelyn Gilbert

Biology Student Scholarship

The frosted elfin butterfly (Callophrys irus) is a locally rare Lycaenaid with spotty distribution throughout the eastern United States. As host plant specialists, frosted elfins only lay eggs on two plant species. Yellow wild indigo (Baptisia tinctoria), one of the host plants for this species, is found in abundance at Gavins Pond (Foxboro MA). Since 2000, Massachusetts Butterfly Club members have been informally monitoring the frosted elfin population at this site; however, no systematic population surveys have been done. Using their data, I estimated annual population size from 2000 to 2022. In 2022, I also performed …

The Effects Of Prescribed Fire On Ant-Mediated Seed Dispersal In Missouri, Eva M. Colberg

Dissertations

Many aspects of animal-mediated seed dispersal are vulnerable to disturbance, including partner identity and dispersal quantity and quality. This dissertation explores ant-mediated seed dispersal of the herb Sanguinaria canadensis in Missouri Ozark oak forests, where prescribed fire is a common land management tool. In Chapter 1, I test the definition of a keystone seed disperser using absolute and relative contributions of different ant species to the quantity and distance of seed dispersal, based on field observations of S. canadensis seed dispersal. I demonstrate that the ant Aphaenogaster rudis is better described as a numerically dominant rather than keystone seed disperser, …
