Compensating For Effects Of Autotomy On Locomotion In Stink Bugs (Halyomorpha Halys), Lilian C. Jubb

Longwood Senior Thesis Proposal

Autotomy is the voluntary release of an appendage, typically to avoid predation or entrapment. Autonomy of a single leg can have minimal effects on locomotion in arthropods with more than six legs. Hexapods, however, use a double-tripod gait which is completely disrupted with the loss of a single leg, thus locomotor performance should be greatly reduced leading to lower survival. Autotomy is so costly to locomotion that some insects regenerate a lost limb in a subsequent molt leading to reduced investment in other important functions (e.g. reproduction). Autotomy persists in adult hexapods with no opportunity for regeneration, which suggests some …

The Pepsis Menechma Lepeletier (Hymenoptera: Pompilidae: Pepsinae) Taxonomic And Nomenclatural Problem, Frank E. Kurczewski

Insecta Mundi

Hurd (1952), in revising the Nearctic species of Pepsis Fabricius, separated P. cerberus Lucas from P. elegans Lepeletier based on external morphology and geography. Vardy (2005), in his Western Hemisphere Pepsis revision, combined these taxa and several Neotropical color and structural variants in a broad defini­tion of P. menechma Lepeletier extending across ~11,250 km and two continents. Vardy (2005) synonymized the familiar and well-documented, 160-year-old P. elegans under P. menechma probably because it appeared several pages later in Lepeletier’s (1845) Histoire Naturelle des Insectes. Hyménoptères. Vardy’s (2005) interpre­tation of Pepsis menechma as a viable species presents a taxonomic and …

Establishment Of Sinoxylon Anale Lesne (Coleoptera: Bostrichidae) In Brazil And Its Potential Implications, Luana De Souza Covre, Robert A. Hack, Carlos A.H. Flechtmann

Insecta Mundi

Bostrichidae (Coleoptera) are a family of beetles with specialized xylophagous feeding habits that allow consumption of dry woody plant tissues. Bostrichids are often polyphagous and therefore pose a sig­nificant threat to many agricultural and forestry products, particularly in tropical regions. Bostrichids are commonly detected in solid wood packaging material at international ports of entry. Notably, Sinoxylon anale Lesne has been intercepted in wood crates and pallets worldwide and has now become established in Brazil. This paper reports the first documented establishment of S. anale in Brazil, being found both in domestic wood pallets and within native forest and monoculture. The …

Chalcochares Hirsutifemur (Banks) (Hymenoptera: Pompilidae: Pompilinae), A Probable Obligate Parasitoid Of Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae) In California, Frank E. Kurczewski, Alice J. Abela, Akira Shimizu

Insecta Mundi

Size equivalence, seasonal synchronicity, geospatial sympatry, habitat specificity, and host-search­ing behavior implicate the spider wasp Chalcochares hirsutifemur (Banks) (Hymenoptera: Pompilidae: Pompilinae) as an obligate parasitoid on species of the wafer-lid spider genus Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae) on coastal sandy back dunes in San Luis Obispo and Santa Barbara coun­ties, CA. This is substantiated by 2010–2022 macrophotographs, videos, and field observations. Such host evidence supports recent unpublished phylogenomic studies that place Chalcochares as a sister genus of the spider wasp tribe Aporini, in which all species are known obligate parasitoids on trapdoor spiders and related Mygalomorphae. Chalcochares hirsutifemur and C. …

The Effect Of Symbioses Between Mold Mites (Acaridae: Tyrophagus Putrescentiae) And Aspergillus Flavus On Their Respective Populations In Stored Maize., Paige Pionke Cummins

Graduate Theses and Dissertations

Zea mays is the most commonly grown grain in the world and is used for animal feed, human consumption, and the creation of other products such as ethanol and bioplastics. Contamination of stored maize with stored grain invaders can lead to loss of revenue, reduced food availability, and potential health complications. Two such storage invaders; the mold mite Tyrophagus putrescentiae and the fungus Aspergillus flavus can work as symbionts within the grain storage system. To determine resulting population growth from this symbiosis, maize was inoculated with three treatments: A. flavus with no mites, T. putrescentiae with no fungus, and both …

Do Species Matter? Examining The Niche Of White Ash (Fraxinus Americana L.) And Estimating Potential Subcanopy Effects Of Its Loss In North-Temperate Forests, Elizabeth Anne Studer

Dartmouth College Ph.D Dissertations

To understand the downstream consequences of the extinction of a species, we must understand its role in an ecosystem. With the impending extirpation of ash (Fraxinus spp.) due to the invasive emerald ash borer (Agrilus planipennis), understanding the role of ash trees is critical to predicting whether its loss will precipitate further species declines and/or ecosystem functions. We evaluated whether subcanopy microbial, invertebrate, and floral communities under four tree species (white ash, American beech, yellow birch, sugar maple) and on two soil hydropedological types (Bh podzol and Typical podzol) varied in species richness, composition, and functional traits in a factorial …

Dietary Parental Effects In A Generalist Heribivore, Emma J. Sellers

Undergraduate Theses, Capstones, and Recitals

The environment or experiences of a parent generation can impact the fitness of the next generation, a phenomenon known as parental effects. The parental diet, for example, can have consequences for their offspring who may perform better or worse on the same diet. Dietary specialists are often the focus of studies of parental effects due to diet because a narrow diet breadth suggests that the offspring environment may be predictable. Dietary generalists, in contrast, are less often studied regarding parental effects and this may be because their wide diet breadth makes the future environment less predictable.

We investigated whether parental …

Determining The Impact Of Post-Harvest Water Management On Chironomid Abundance, Agrochemical Biomass And Potential Trophic Biomagnification, Mason Thomas

Theses and Dissertations

Agriculture has diminished shorebirds’ natural habitat in the Mississippi Alluvial Valley. Remaining natural stopover sites are supplemented with agricultural fields during the fall and winter. This study evaluates the impact of 4 different post-harvest water management strategies on shorebird food abundance and potential agrochemical biomagnification. Chironomid samples estimated abundance, biomass, and chironomid agrochemical concentration in each field. A risk assessment of agrochemical biomagnification to shorebirds was made across all treatments. Of treatments represented on all study sites, winter treatment had greatest chironomid abundance and biomass. Models indicated that days since flood initiation, start date, and temperature are significant predictors of …
