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
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 …
Fates Of Ovules In Groundplum Milk-Vetch (Astragalus Crassicarpus Nutt.) In South Dakota, Arvid Boe, Paul J. Johnson
Fates Of Ovules In Groundplum Milk-Vetch (Astragalus Crassicarpus Nutt.) In South Dakota, Arvid Boe, Paul J. Johnson
Native Plant Focused Publications
Groundplum milk-vetch (Astragalus crassicarpus Nutt.) is a native legume found on gravelly to sandy prairie uplands throughout central North America. The large and fleshy fruits, or pods, of this species were consumed by indigenous people and European settlers, and are cached by rodents. Our previous research on native legumes of the northern Great Plains indicated seed predation by insects, notably bruchid beetles belonging to the genus Acanthoscelides Schilsky, was a dominant factor determining viable seed production in natural and artificial plant assemblages. However, although we have studied the reproductive biology of several species of Astragalus L., none had fleshy pods. …

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
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 …

Annotated World Bibliography Of Host Plants Of The Melon Fly, Bactrocera Cucurbitae (Coquillett) (Diptera: Tephritidae), Grant T. Mcquate, Nicanor J. Liquido, Kelly A. A. Nakamichi
Insecta Mundi
The melon fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae), is a widespread, economically important tephritid fruit fly species. Bactrocera cucurbitae infests fruits and vegetables of a number of different plant species, with many host plants in the plant family Cucurbitaceae, but with additional hosts scattered across many other plant families. Although thought to be native to India, its distribution has spread throughout many countries in Oriental Asia, into a number of Pacific Island nations, and into Africa. The documented introductions into countries outside its native distribution show that this species could establish in other countries where it does not presently occur, …

Population Dynamics Of The Wheat Curl Mite (Acari: Eriophyidae) During The Heading Stages Of Winter Wheat, Anthony J. Mcmechan, Gary Hein
Population Dynamics Of The Wheat Curl Mite (Acari: Eriophyidae) During The Heading Stages Of Winter Wheat, Anthony J. Mcmechan, Gary Hein
Department of Entomology: Faculty Publications
The wheat curl mite (Aceria tosichella Keifer) is the only known vector of three viruses in wheat—Wheat streak mosaic virus, Wheat mosaic virus, and Triticum mosaic virus. The economic impact of this disease complex is linked to the presence of suitable hosts prior to winter wheat maturing in early summer and the movement of wheat curl mite from wheat to oversummering hosts prior to wheat harvest. Previous research has documented the prevalence and density of mite populations on maturing wheat heads; however, these studies were limited to a few late stages of wheat. A study was conducted …

Record Breaking Achievements By Spiders And The Scientists Who Study Them, Stefano Mammola, Peter Michalik, Eileen Hebets, Marco Isaia
Eileen Hebets Publications
Organismal biology has been steadily losing fashion in both formal education and scientific research. Simultaneous with this is an observable decrease in the connection between humans, their environment, and the organisms with which they share the planet. Nonetheless, we propose that organismal biology can facilitate scientific observation, discovery, research, and engagement, especially when the organisms of focus are ubiquitous and charismatic animals such as spiders. Despite being often feared, spiders are mysterious and intriguing, offering a useful foundation for the effective teaching and learning of scientific concepts and processes. In order to provide an entryway for teachers and students—as well …

Rag1 Soybean Photosynthetic Response To Biotype 2 Aphid Colonization And Feeding, Katy Hillard
Department of Entomology: Distance Master of Science Projects
Over the past ten years, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), has been one of the principal insect threats to commercial soybean, Glycine max (L.) Merr., production in the United States. Resistance genes identified from native soybean have been incorporated into commercial varieties to provide protection against aphid feeding damage. The biology of the pest lends itself to rapid buildup of biotypes capable of overcoming host plant resistance. Single gene resistance sources have displayed low levels of durability against aphids. The first aphid resistant commercial soybean line released in the United States contained the Rag1 gene, which was …

Use Of Baited Attract And Kill Stations As Ipm Alternative To Control Invasive Drosophila Suzukii Matsumura (Spotted Wing Drosophila), Timothy Lampasona
Department of Entomology: Distance Master of Science Projects
The newly invasive Drosophila suzukii Matsumura (Spotted Wing Drosophila, SWD) is an economically significant pest of berries and other small fruit in the Northeast United States. Methods of controlling this insect typically consist of frequent sprays of conventional insecticide, often with long pre-harvest intervals. This experiment is intended to determine the efficacy of a unique Attract and Kill (AtK) design using super-absorbent gelatinous media saturated with highly attractive SWD bait adhered to durable netting, sprayed regularly with a range of insecticides. Our lab and field studies determined that presence of AtK stations treated with insecticides placed in vicinity of raspberries …
