Variable Consequences Of Toxic Prey On Generalist Insect Predators, Kelly Jackson Jan 2016

Variable Consequences Of Toxic Prey On Generalist Insect Predators, Kelly Jackson

Theses and Dissertations--Entomology

Introduced species, like the lady beetle Harmonia axyridis, have been linked to declines of native species through mechanisms including intraguild predation and competitive superiority. However, competitive differentials between species may be mitigated if subdominant species can utilize resources that dominant species cannot. Previous research has shown that some strains of the aphid Aphis craccivora are toxic to H. axyridis. My goal was to investigate use of this resource by both H. axyridis and other lady beetles, to determine whether these aphids might be an exploitable resource for subdominant lady beetle species. I first examined the behavioral responses of …

The Manipulation And Examination Of Wolbachia In Medically Important Mosquitoes, Timothy D. Mcnamara Jan 2016

The Manipulation And Examination Of Wolbachia In Medically Important Mosquitoes, Timothy D. Mcnamara

Theses and Dissertations--Entomology

Mosquitoes are a major vector of human disease and result in massive costs to public health in affected regions. It has been suggested that Wolbachia pipientis could be used for mosquito population reduction. Wolbachia is a maternally-transmitted endosymbiont of arthropods and nematodes that infects the cytoplasm of host cells. In mosquitoes, Wolbachia manipulates reproduction through Cytoplasmic Incompatibility (CI), which is characterized by a cessation of embryonic development in certain crossing-types. However, the relationship between Wolbachia and its host is complex and not fully understood. The crossing relationships between naturally-infected and aposymbiotic populations of Culex pipiens pipiens and Culex pipiens molestus …

The Chemical Ecology Of Bed Bugs (Cimex Lectularius, L.) And The Impact Of A Neurotoxic Insecticide On Physiology And Behavior, Sydney E. Crawley Jan 2016

The Chemical Ecology Of Bed Bugs (Cimex Lectularius, L.) And The Impact Of A Neurotoxic Insecticide On Physiology And Behavior, Sydney E. Crawley

Theses and Dissertations--Entomology

Following a decades-long hiatus in many nations, populations of bed bugs (Cimex lectularius) have rebounded and are thriving on a global scale posing substantial challenges for pest management professionals. Insecticide resistance to both pyrethroid and neonicotinoid compounds has been identified in many populations, leading to renewed interest in alternative control methods for management of this pest. The objectives of my dissertation research were to study various, typically cryptic, bed bug behaviors in order to improve both conventional and alternative management strategies. Novel behavioral interactions among mother and offspring were characterized. Additionally, changes in behavior and physiology after treatment …

Endosymbiotic Bacteria In The Bed Bug, Cimex Lectularius L. (Hemiptera: Cimicidae), Mark H. Goodman Jan 2016

Endosymbiotic Bacteria In The Bed Bug, Cimex Lectularius L. (Hemiptera: Cimicidae), Mark H. Goodman

Theses and Dissertations--Entomology

The return of bed bugs to prominence as an urban pest has precipitated an emphatic research response from the scientific community in an effort to better understand their biology and management. However, not all aspects of bed bug biology have received equal attention. The role of symbiotic bacteria in the normal function and biology of insects is often underappreciated, and this is true of bed bugs. Bed bugs have two main endosymbiotic bacteria, a Wolbachia species and a poorly-characterized gamma-proteobacterium referred to as BLS. However, their interactions with the host are poorly understood. I explored various aspects of these symbionts …

Differential Gene Expression Of Minnesota (Mn) Hygienic Honeybees (Apis Mellifera) Performing Hygienic Behavior, Eric Northrup Jan 2016

Differential Gene Expression Of Minnesota (Mn) Hygienic Honeybees (Apis Mellifera) Performing Hygienic Behavior, Eric Northrup

All Graduate Theses, Dissertations, and Other Capstone Projects

Hygienic behavior is the ability to remove dead and diseased brood from the comb early as to limit the detrimental impact of the parasite or pathogen. Minnesota (MN) Hygienic bees are generalists of hygienic behavior with the ability to remove several brood infected with several pathogens including the Varroa mite. This study explored the mechanisms of MN Hygienic behavior by comparing the transcriptome of MN Hygienic bee brains to non-hygienic bee brains via cDNA microarray. The results suggest that the brains of MN Hygienic bees may have a greater number of dendritic connections or are more sensitive to neurotransmitters. Quantitative …

Species Distribution Modeling Of North American Odonates, Rebecca Beilinson Jan 2016

Species Distribution Modeling Of North American Odonates, Rebecca Beilinson

Library Map Prize

Species distribution modeling, which uses species-environment relationships to predict species’ geographic ranges, is a powerful technique for biogeographical and ecological analysis as well as for conservation planning. However, it has typically been underutilized for invertebrates and for freshwater species, as modeling these groups can pose unique challenges. Here I present methods for modeling odonate distributions and demonstrate these methods for four North American species. I show that incorporating expert-derived range maps as spatial priors can significantly improve model performance as compared to MaxEnt models. I also introduce a new distance to freshwater layer as an environmental variable, and show that …

Ant Diversity And Community Structure In Coastal Dunes And Wetlands, Xuan Chen Jan 2016

Ant Diversity And Community Structure In Coastal Dunes And Wetlands, Xuan Chen

LSU Doctoral Dissertations

How do many species live in a certain place? How does species composition changes among habitats? And what mechanisms decide species distribution? These are fundamental questions in community ecology. I first investigated ant diversity in two coastal ecosystems (dunes and wetlands) in the northern Gulf of Mexico, and then used the distribution patterns to infer assembly processes that structure ant communities in coastal areas. Specifically, the following hypotheses are tested: (1) coastal systems support lower ant diversity due to the unsuitable environment; (2) species living near the seashore are a subset of those exist near inland; (3) deterministic processes are …

Mexican Rice Borer (Eoreuma Loftini) Pheromone Trap Efficacy And Role In Invasive Species Monitoring And Pest Management, Blake Emerson Wilson Jan 2016

Mexican Rice Borer (Eoreuma Loftini) Pheromone Trap Efficacy And Role In Invasive Species Monitoring And Pest Management, Blake Emerson Wilson

LSU Doctoral Dissertations

The Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), is an invasive pest of sugarcane, Saccharum spp.; rice, Oryza sativa; and other graminaceous crops along the U.S. Gulf Coast. Identification of E. loftini sex pheromones led to the development of pheromone baited traps. Studies were conducted to determine strategies for the use of E. loftini pheromone traps in invasive species monitoring and pest management. A two-year field study demonstrated that E. loftini pheromone traps attract males from distances of up to 100m. A behavioral assay observed that detection of the pheromone by E. loftini males occurs at ≈48m from the …

Effects Of Truck Based Ultra-Low Volume Mosquito Adulticides On Honey Bees (Apis Mellifera) In A Real World Scenario, Vivek Pokhrel Jan 2016

Effects Of Truck Based Ultra-Low Volume Mosquito Adulticides On Honey Bees (Apis Mellifera) In A Real World Scenario, Vivek Pokhrel

LSU Master's Theses

Honey bees are crucial pollinators for many economically important fruit crops. The recent honey bee colony decline in the United States and other regions of the world has caused concern among commercial beekeepers, research groups, the government, and the general public. The role of pesticides in recent honey bee declines has not been fully determined. In Louisiana, it is a common practice to spray truck based ultra-low volume mosquito adulticides in Integrated Mosquito Management Programs to control mosquitoes and minimize the risk of vector borne viruses such as West Nile, chikungunya, and Zika. This study measured the effects of truck …

The Ticks (Arachnida: Acari: Ixodida) Of Arkansas, C. T. Mcallister, L. A. Durden, H. W. Robison

Journal of the Arkansas Academy of Science

Although ticks are a nuisance to humans and other animals, they are an important part of the biota of North America. In addition, they are vectors of many tick-borne disease agents that can negatively affect higher vertebrates. In Arkansas, there have been no recent comprehensive summaries of the ticks (Acari: Ixodida) in the last 40+ yrs. Here, we provide a summary of the ticks of the state and note the disease agents they can transmit.

Evidence Of Female Sex Pheromones And Characterization Of The Cuticular Lipids Of Unfed, Adult Male Versus Female Blacklegged Ticks, Ixodes Scapularis, Ann L. Carr, Daniel E. Sonenshine, John B. Strider Jr., R. Michael Roe

Biological Sciences Faculty Publications

Copulation in I. scapularis involves physical contact between the male and female (on or off the host), male mounting the female, insertion/maintenance of the male chelicerae in the female genital pore (initiates spermatophore production), and the transfer of the spermatophore by the male into the female genital pore. Bioassays determined that male mounting behavior/chelicerae insertion required direct contact with the female likely requiring non-volatile chemical cues with no evidence of a female volatile sex pheromone to attract males. Unfed virgin adult females and replete mated adult females elicited the highest rates of male chelicerae insertion with part fed virgin adult …

Research outputs 2014 to 2021

Intensifying global trade will result in increased numbers of plant pest and pathogen species inadvertently being transported along with cargo. This paper examines current mechanisms for prevention and management of potential introductions of forest insect pests and pathogens in the European Union (EU). Current European legislation has not been found sufficient in preventing invasion, establishment and spread of pest and pathogen species within the EU. Costs associated with future invasions are difficult to estimate but past invasions have led to negative economic impacts in the invaded country. The challenge is combining free trade and free movement of products (within the …

Land-Use Change Reduces Habitat Suitability For Supporting Managed Honey Bee Colonies In The Northern Great Plains, Clint R. V. Otto, Cali L. Roth, Benjamin L. Carlson, Matthew D. Smart Jan 2016

Land-Use Change Reduces Habitat Suitability For Supporting Managed Honey Bee Colonies In The Northern Great Plains, Clint R. V. Otto, Cali L. Roth, Benjamin L. Carlson, Matthew D. Smart

Department of Entomology: Faculty Publications

Human reliance on insect pollination services continues to increase even as pollinator populations exhibit global declines. Increased commodity crop prices and federal subsidies for biofuel crops, such as corn and soybeans, have contributed to rapid land-use change in the US Northern Great Plains (NGP), changes that may jeopardize habitat for honey bees in a part of the country that supports >40% of the US colony stock. We investigated changes in biofuel crop production and grassland land covers surrounding ~18,000 registered commercial apiaries in North and South Dakota from 2006 to 2014. We then developed habitat selection models to identify remotely …

The Influence Of Photoperiod On Development Rates Of Three Species Of Forensically Important Blow Flies, M. L. Fisher, Leon G. Higley, John E. Foster Jan 2016

The Influence Of Photoperiod On Development Rates Of Three Species Of Forensically Important Blow Flies, M. L. Fisher, Leon G. Higley, John E. Foster

Department of Entomology: Faculty Publications

Environmental factors, such as temperature and photoperiod can play important roles in insect development. Numerous studies have researched insects and their responses to photoperiod, but there has been little research to show if the duration of light alters development rates in blow flies. A review of previous literature revealed differences in the light regime (L:D) reported for the study. This study examined the effects of photoperiod on development rates of Phormia regina Meigen, Cochliomyia macellaria F., and Calliphora vicina Robineau-Desvoidy using four light regimes of 0, 12, 16, and 24 h of light measured at both 20C and 26C.

Stress-Induced Changes In Abundance Differ Among Obligate And Facultative Endosymbionts Of The Soybean Aphid, Laramy S. Enders, Nicholas Miller Jan 2016

Stress-Induced Changes In Abundance Differ Among Obligate And Facultative Endosymbionts Of The Soybean Aphid, Laramy S. Enders, Nicholas Miller

Department of Entomology: Faculty Publications

Bacterial endosymbionts can drive evolutionary novelty by conferring adaptive benefits under adverse environmental conditions. Among aphid species there is growing evidence that symbionts influence tolerance to various forms of stress. However, the extent to which stress inflicted on the aphid host has cascading effects on symbiont community dynamics remains poorly understood. Here we simultaneously quantified the effect of host-plant induced and xenobiotic stress on soybean aphid (Aphis glycines) fitness and relative abundance of its three bacterial symbionts. Exposure to soybean defensive stress (Rag1 gene) and a neurotoxic insecticide (thiamethoxam) substantially reduced aphid composite fitness (survival 9 reproduction) …

Plant Tolerance: A Unique Approach To Control Hemipteran Pests, Kyle G. Koch, Kaitlin Chapman, Joe Louis, Tiffany Heng-Moss, Gautam Sarath Jan 2016

Plant Tolerance: A Unique Approach To Control Hemipteran Pests, Kyle G. Koch, Kaitlin Chapman, Joe Louis, Tiffany Heng-Moss, Gautam Sarath

Department of Entomology: Faculty Publications

Plant tolerance to insect pests has been indicated to be a unique category of resistance, however, very little information is available on the mechanism of tolerance against insect pests. Tolerance is distinctive in terms of the plant’s ability to withstand or recover from herbivore injury through growth and compensatory physiological processes. Because plant tolerance involves plant compensatory characteristics, the plant is able to harbor large numbers of herbivores without interfering with the insect pest’s physiology or behavior. Some studies have observed that tolerant plants can compensate photosynthetically by avoiding feedback inhibition and impaired electron flow through photosystem II that occurs …

Department of Entomology: Faculty Publications

RNA interference (RNAi) has become a widely used reverse genetic tool to study gene function in eukaryotic organisms and is being developed as a technology for insect pest management. The efficiency of RNAi varies among organisms. Insects from different orders also display differential efficiency of RNAi, ranging from highly efficient (coleopterans) to very low efficient (lepidopterans). We investigated the reasons for varying RNAi efficiency between lepidopteran and coleopteran cell lines and also between the Colorado potato beetle, Leptinotarsa decemlineata and tobacco budworm, Heliothis virescens. The dsRNA either injected or fed was degraded faster in H. virescens than in L. …

Department of Entomology: Faculty Publications

Drosophila suzukii (Matsumura) is an economic pest of small fruits and cherries that attacks intact ripening fruits. Host susceptibility may be influenced by characteristics such as flesh firmness, penetration force of the skin, total soluble solids (TSS, also known as Brix), and pH. Improved knowledge of factors affecting fruit susceptibility is needed for developing thresholds and risk prediction models for IPM. A combination of laboratory and field studies was conducted to develop prediction and potential management tools. First, a direct bioassay was used to calculate the probability of oviposition in a given fruit based on various characteristics as determined across …

High Levels Of Resistance In The Common Bed Bug, Cimex Lectularius (Hemiptera: Cimicidae), To Neonicotinoid Insecticides, Alvaro Romero, Troy D. Anderson

Department of Entomology: Faculty Publications

The rapid increase of bed bug populations resistant to pyrethroids demands the development of novel control tactics. Products combining pyrethroids and neonicotinoids have become very popular for bed bug control in the United States, but there are concerns about evolution of resistance to these compounds. Laboratory assays were used to measure the toxicity of topical applications of four neonicotinoids to a susceptible population and three pyrethroid-resistant populations. Activity of esterases, glutathione S-transferases, and cytochrome P450s of all strains was also evaluated. High levels of resistance to four neonicotinoids, acetamiprid, imidacloprid, dinotefuran, and thiamethoxam, relative to the susceptible Fort Dix population, …

Differential Gene Expression In Varroa Jacobsoni Mites Following A Host Shift To European Honey Bees (Apis Mellifera), Gladys K. Andino, Michael R. Gribskov, Denis L. Anderson, Jay D. Evans, Greg Hunt Jan 2016

Differential Gene Expression In Varroa Jacobsoni Mites Following A Host Shift To European Honey Bees (Apis Mellifera), Gladys K. Andino, Michael R. Gribskov, Denis L. Anderson, Jay D. Evans, Greg Hunt

Department of Entomology Faculty Publications

Background: Varroa mites are widely considered the biggest honey bee health problem worldwide. Until recently, Varroa jacobsoni has been found to live and reproduce only in Asian honey bee (Apis cerana) colonies, while V. destructor successfully reproduces in both A. cerana and A. mellifera colonies. However, we have identified an island population of V. jacobsoni that is highly destructive to A. mellifera, the primary species used for pollination and honey production. The ability of these populations of mites to cross the host species boundary potentially represents an enormous threat to apiculture, and is presumably due to genetic variation that exists …
