Larval Pollen Stress Increases Adult Susceptibility To Clothianidin In Honey Bees, Christina L. Mogren, Robert G. Danka, Kristen B. Healy

Faculty Publications

Neonicotinoid insecticides have come under scrutiny for their potential role in honey bee declines. Additionally, reduced access to forage in agricultural areas creates the potential for risk interactions with these pesticides in regions critical for honey production. In this study, we sought to determine whether sufficient access to pollen during larval development could mitigate stress associated with oral clothianidin exposure in honey bee adults. An apiary was established where pollen traps deprived half of the colonies of pollen, which was then supplemented to the others. Adults were fed 0, 10, 40, 200, or 400 µg/L clothianidin in the laboratory, and …

Management Of Economically Important Insect Pests Of Millet, Ruparao T. Gahukar, Gadi V.P. Reddy, Tom Royer

Faculty Publications

Grain of various species of millet is a staple food of rural communities in sub-Saharan Africa, the Indian subcontinent, and China. In addition, millet is used as poultry and cattle feed in the United States, and the foliage is fodder for cattle in India. The crop is damaged by at least 150 insect pests during its growth and development. Although the current status of all of these pests is not known, shoot flies, stem borers, leaf-sucking, and the panicle-attacking insects are considered economically important. Control measures include the application of synthetic pesticides (as both seed treatment and foliar applications) and …

Bottom-Up Trait-Mediated Indirect Effects Decrease Pathogen Transmission In A Tritrophic System, Bret D. Elderd

Faculty Publications

© 2018 by the Ecological Society of America A plant's induction of secondary defenses helps to decrease herbivore damage by changing resource quality. While these chemical or physical defenses may directly decrease herbivory, they can also have indirect consequences. In a tritrophic system consisting of a plant, an insect herbivore, and an insect pathogen, plant based trait-mediated indirect effects (TMIEs) can alter host–pathogen interactions and, thereby, indirectly affect disease transmission. In a series of field experiments, individual soybean plants (Glycine max) were sprayed with either a jasmonic acid (JA) solution to trigger induction of plant defenses or a similar control …

Diet Of Lesser Scaup Wintering On Lake Pontchartrain, Louisiana, Clay M. Stroud, Claire E. Caputo, Michael A. Poirrier, Kevin M. Ringelman

Faculty Publications

The lesser scaup Aythya affinis has been a species of conservation concern since continental breeding populations began declining in the 1980s. The causes of this decline are likely multifaceted, but cross-seasonal effects are believed to play a prominent role: females unable to acquire sufficient nutrient reserves during winter and spring migration have poor survival and breeding success. Understanding scaup diet composition and prey selection can help managers not only diagnose mechanisms underlying wintering scaup distributions, but may also help direct management actions to increase forage availability and quality. We evaluated the diet of 60 scaup collected from a major wintering …

Faculty Publications

Core Ideas: Application of urea led to higher N2O emissions than urea–ammonium nitrate in sugarcane. Residue retention led to higher N2O and CH4 emissions irrespective of N source. Both N source and residue management did not affect CO2 emissions. Sugarcane (Saccharum spp.) is a major row-crop in the southern United States with high rates of N-fertilizer application and unique harvest-residue management. A 2-yr field experiment was conducted to investigate different N-fertilizer effects (urea and urea ammonium nitrate, UAN) and harvest-residue managements (residue-retain, RR, and residue-burn, RB) on greenhouse gas (GHG) emissions from soils under sugarcane production. In 2012, a split-plot …

Advanced Analysis Of Compounds Of Toxicological Importance By Ice Concentration Linked With Extractive Stirrer (Icecles) Gc-Ms And Rp-Hplc-Esi-Ms-Ms, Joseph K. Dzisam

Electronic Theses and Dissertations

Cyanide and nitrosoamines (NAs) are ubiquitous compounds, found in our food and water, either by natural process or through man-made activities. The toxicity of cyanide is exerted by its ability to inhibit metalloenzymes such as cytochrome c oxidase, causing concomitant cascades of biochemical effects such as lactic acidosis, inhibition of ATP production, respiratory seizure, and potential death. Nitrosoamines, on the other hand, undergo biotransformation (metabolic activation in cytochrome P450) in the body to produce unstable intermediates that alkylate DNA, causing mutations, and leading to carcinogenesis. In order to further the advancement of a promising cyanide, cobinamide (Cbi), an LC-MS-MS method …
