Development Of Site Fidelity In The Nocturnal Amblypygid, Phrynus Marginemaculatus, Jacob M. Graving, Verner P. Bingman, Eileen Hebets, Daniel D. Wiegmann

Eileen Hebets Publications

Amblypygids are capable of navigation in the complex terrain of rainforests in near complete darkness. Path integration is unnecessary for successful homing, and the alternative mechanisms by which they navigate have yet to be elucidated. Here, our aims were to determine whether the amblypygid Phrynus marginemaculatus could be trained to reliably return to a target shelter in a laboratory arena—indicating goal recognition—and to document changes in behavior associated with the development of fidelity. We recorded nocturnal movements and space use by individuals over five nights in an arena in which subjects were provided with two shelters that differed in quality. …

An Entomological Survey Of Camp Arifjan, Kuwait, Comparing Species Richness Between Different Areas And Degrees Of Human Use, Ronald Hirzel

Department of Entomology: Distance Master of Science Projects

The insect fauna of Camp Arifjan, Kuwait was sampled to determine species richness and how it was impacted by human development and activities. Insects were sampled at twelve sites representing three each of work, public use, residential and vacant brownfield areas. Sampling was conducted using net, sticky trap and pit traps for 60 days. Sticky traps were discarded as unworkable. The first of each species captured from each site was retained as a voucher specimen. Specimens were determined to lowest level possible using a dissecting microscope, available literature and the internet. Collecting and trapping obtained 355 specimens representing 170 species. …

Effects Of Temperature And Diet In Stable Fly (Diptera: Muscidae) Development, Melina Florez-Cuadros

Department of Entomology: Dissertations, Theses, and Student Research

Stable flies are among the most important blood feeding ectoparasites of cattle worldwide. The livestock industry is losing more than $2 billion dollar annually in the United States alone. Moist decaying vegetative material with bacteria supports larval development. Temperature and diet quality are important factors for stable fly development, affecting development rates, adult survival, and size, but how temperature affects adult size and interacts with nutrition is unknown. This study characterizes the relationship of temperature and diet quality in the development of stable flies. Two statistical models were used to analyze the effect of temperature alone (Lysyk, 1998) and temperature-diet …

Dietary Risk Assessment Of V-Atpase A Dsrnas On Monarch Butterfly Larvae, Huipeng Pan, Xiaowei Yang, Keith Bidne, Richard L. Hellmich, Blair Siegfried, Xuguo Zhou

Department of Entomology: Faculty Publications

By suppressing the expression of genes with essential biological functions, in planta RNAi can negatively affect the development and survival of target pests. As a part of a concerted effort to assess the risks of RNAi transgenic crops on non-target organisms, we developed an in vivo toxicity assay to examine the impacts of ingested dsRNAs incurred to the monarch butterfly, Danaus plexippus (L.), an iconic eco-indicator in North America. To create the worst case scenario, the full-length v-ATPase A cDNAs from the target pest, western corn rootworm, Diabrotica virgifera virgifera, and the non-target D. plexippus were respectively cloned. A 400 …

The Red Imported Fire Ant: The Visitor Who Wouldn’T Leave. A Brief Overview Of The Control Of Solenopsis Invicta In The United States, Melissa Brown

Department of Entomology: Distance Master of Science Projects

The ease at which people, plants and animals move across the globe has created the perfect vehicle for transporting pests and disease. The introduction of non-native species into an ecosystem is a cause for great concern. The economic impact alone makes this a situation that effects everyone. The Red Imported Fire Ant, Solenopsis invicta Buren has become a major agricultural and urban pest throughout the southeastern United States. In addition, fire ants cause both medical and environmental harm (Stimac and Alves 1994). The cost associated with the control of the RIFA is significant. An estimated cost of about $36 per …

A Guidebook On Honey Bee Health: Honey Bee Immunity — Pesticides — Pests And Diseases, Joey Caputo

Department of Entomology: Distance Master of Science Projects

Pedigo and Rice (2009) described a concept that some ecologists subscribe to called the “balance of nature” phenomenon. This idea holds that spe-cies in communities achieve certain status in their ecosystem and that this status becomes fixed and resistant to change. On average, individuals are only able to replace themselves. Fluctuations may occur, but ultimately the various species in the community will retain their position and relative population size in the ecosystem. According to these ecologists, when humans alter and reduce the diversity of an ecosystem they are acting counter to this balance. In an attempt to re-turn the altered …

Attack And Defense Movements Involved In The Interaction Of Spodoptera Frugiperda And Helicoverpa Zea (Lepidoptera: Noctuidae), José P. F. Bentivenha, Edson L. L. Baldin, Débora Goulart Montezano, Thomas E. Hunt, Silvana L. Vieira De Paula Moraes

Department of Entomology: Faculty Publications

The fall armyworm, Spodoptera frugiperda (J. E. Smith) and the corn earworm, Helicoverpa zea (Boddie) are among the main pests of maize. Both species exhibit cannibalistic behavior and quite often share the same feeding guild in maize (maize ears), which can result in several interspecific and intraspecific interactions. Paired interaction scenarios of intraspecific and interspecific larvae were assessed in arenas in the presence and absence of food to characterize movements resulting from interactions of these insects. There was a difference in the frequency of behavioral movements in all the interactions, except for S. frugiperda in the presence of food. …

Amitraz And Its Metabolite Modulate Honey Bee Cardiac Function And Tolerance To Viral Infection, Scott T. O'Neal, Carlyle C. Brewster, Jeffrey R. Bloomquist, Troy D. Anderson

Department of Entomology: Faculty Publications

The health and survival of managed honey bee (Apis mellifera) colonies are affected by multiple factors, one of the most important being the interaction between viral pathogens and infestations of the ectoparasitic mite Varroa destructor. Currently, the only effective strategy available for mitigating the impact of viral infections is the chemical control of mite populations. Unfortunately, the use of in-hive acaricides comes at a price, as they can produce sublethal effects that are difficult to quantify, but may ultimately be as damaging as the mites they are used to treat. The goal of this study was to …

Effects Of Neonicotinoid Imidacloprid Exposure On Bumble Bee (Hymenoptera: Apidae) Queen Survival And Nest Initiation, Judy Wu-Smart, Marla Spivak

Department of Entomology: Faculty Publications

Neonicotinoids are highly toxic to insects and may systemically translocate to nectar and pollen of plants where foraging bees may become exposed. Exposure to neonicotinoids can induce detrimental sublethal effects on individual and colonies of bees and may have long-term impacts, such as impaired foraging, reduced longevity, and reduced brood care or production. Less well-studied are the potential effects on queen bumble bees that may become exposed while foraging in the spring during colony initiation. This study assessed queen survival and nest founding in caged bumble bees [Bombus impatiens (Cresson) (Hymenoptera: Apidae)] after chronic (18-d) dietary exposure of imidacloprid …

Morphological Revision Of The Western Palaearctic Species Of The Genus Copris Geoffroy, 1762 With Three Foretibial External Teeth (Coleoptera: Scarabaeoidea: Scarabaeidae), Stefano Ziani

Insecta Mundi

This revision concerns a small group of Western Palaearctic Copris species (Coleoptera: Scarabaeoidea: Scarabaeidae) distinguished by having three lateral teeth on the foretibae.
