Imported Fire Ant(Hymenoptera: Formicidae) Mound Distribution Relationships In Connection To The Heterogeneity Of Ten Christmas Tree Farm Landscapes In Mississippi, S. R. Self, T. E. Nebeker

Midsouth Entomologist

Ten Christmas tree farms were selected as research sites across Mississippi. At each site a 10-percent inventory was established. Plots were chosen randomly, and all imported fire ant (IFA) (Hymenoptera: Formicidae, Solenopsis spp.) mound positions inside the plot boundaries were captured as global positioning system (GPS) points. Mound points, along with their corresponding volumes (cm3), were recorded and uploaded into ESRI® ArcMap for analysis. Thirteen variables were selected to represent the heterogeneity of these landscapes. Among those variables, the species, height, and diameter of every Christmas tree located inside a plot were recorded, along with average grass height, distance to …

2010 Soybean Insect Losses For Mississippi, Tennessee, And Arkansas, F. R. Musser, G. M. Lorenz, S. D. Stewart, A. L. Catchot Jr.

Midsouth Entomologist

Survey-based soybean insect losses provide a glimpse of current soybean management practices and allow the detection of evolving trends. This survey was initiated in Mississippi in 2004, Tennessee in 2008, and Arkansas in 2009. The 2010 survey shows stink bugs and corn earworm caused similar amounts of damage in the region. Combined, these two insects caused more than half of all insect losses in 2010. Insect scouting and the adoption of seed treatments were at similar levels compared to 2009.

Efficacy Of Cotton Expressing Pyramided Bacillus Thuringiensis Insecticidal Proteins Against Lepidopteran Pest, D. S. Akin, S. D. Stewart, M. B. Layton, J. A. Mills

Midsouth Entomologist

Laboratory, greenhouse, and field experiments were conducted to evaluate the efficacy of cotton (Gossypium hirsutum L.) expressing two proteins of Bacillus thuringiensis Berliner (‘Bollgard II’ expressing Cry1Ac + Cry2Ab, Monsanto Company, St. Louis, MO) against economically important lepidopteran pests in Mississippi. Results from leaf assays conducted in the laboratory indicate that Bollgard II cotton caused significantly higher mortality and growth inhibition of Helicoverpa zea (Boddie), Heliothis virescens (F.), Spodoptera frugiperda (J.E. Smith), S. exigua (Hubner), Pseudoplusia includes (Walker), and Estigmene acrea (Drury) than Cry1Ac onlyand non-Bt cotton. In greenhouse studies, Bollgard II cotton provided significantly enhanced protection against common defoliating …

Transfected Mosquito Vectors, Stephen L. Dobson

Entomology Faculty Patents

A method is provided for producing an artificial infection in a Culicidae (mosquito) species. The mosquitoes include species within the subfamilies Culicinae and Anophelinae, and the species include Aedes albopictus, Aedes aegypti and Aedes polynesiensis infected with a Wolbachia infection. The infection may be a strain of Wolbachia which does not normally or naturally infect the selected mosquito species. The artificially infected Aedes mosquito can be introduced into a mosquito population to control the reproduction capability of the population by introducing an incompatible Wolbachia infection. The present method can be used as a novel means to limit mosquito-borne pathogens and …

Interactions Of Transgenic Bacillus Thuringiensis Insecticidal Crops With Spiders (Araneae), Julie A. Peterson, Jonathan Lundgren, James D. Harwood

Department of Entomology: Faculty Publications

Genetically modified crops expressing insecticidal proteins from Bacillus thuringiensis (Bt) have dramatically increased in acreage since their introduction in the mid-1990’s. Although the insecticidal mechanisms of Bt target specific pests, concerns persist regarding direct and indirect effects on non-target organisms. In the field, spiders may be exposed to Bt toxins via multiple routes, including phytophagy and pollenivory, consumption of Bt-containing prey, and soil exudates in the detrital food web. Beyond direct toxicity, Bt crops may also have indirect impacts, including pleiotropic and preymediated effects. Here, we comprehensively review the literature and use meta-analyses to reveal that foliar spider abundance is …

Environmental Impact And Cost Benefit Analysis Of Biological Control Application, Jaime Molina-Ochoa, John E. Foster

Department of Entomology: Faculty Publications

The implications and interactions of the application of biological control agents in the environment, as well as the risks included by the introduction of exotic natural enemies are briefly reviewed. Description of the role of resistance or quality of the host plant to insect pests, and their interaction with biocontrol agents is provided. A need to increase applications or find new alternatives and environmental impact towards non target insects, and the real cost of its use against the benefits is discussed.

Biosecurity published reports

Biosecurity is the protection of the economy, environment and human health from the negative impacts of pests, weeds and diseases, including the management of invasive species if they become established (definition adopted by AusBIOSEC).

This requires steps to prevent the entry of harmful organisms, as well as the timely and efficient management of them if they do enter.

Biosecurity threats range from catastrophic diseases such as Foot and Mouth Disease, which causes rapid and widespread animal deaths, to more subtle and slower spreading problems such as invasive weeds, mussels that foul vessel hulls and fungus-induced dieback disease of trees. These …

Agroecological Factors Impacting Stem Borer (Lepidoptera: Crambidae) Dynamics In Gulf Coast Sugarcane And Rice, Julien M. Beuzelin

LSU Doctoral Dissertations

Diatraea saccharalis (F.) and Eoreuma loftini (Dyar) are stem boring pests of sugarcane (Saccharum spp.) and rice (Oryza sativa L.) crops in the Gulf Coast region. Studies were conducted to determine the role of agroecological factors, including predator disruptions, alternate hosts, and crop phenological conditions, on stem borer populations.
The year after Hurricane Rita storm surge flooded sugarcane in Louisiana, a 71% reduction in the predaceous Solenopsis invicta Buren was recorded. Even with a 2.4-fold increase in the number of insecticide applications used for D. saccharalis management in flooded fields, growers still incurred higher injury.
In two field …

Molecular Mechanisms Of Bacillus Thuringiensis Resistance In The Sugarcane Borer, Yunlong Yang

LSU Doctoral Dissertations

The sugarcane borer, Diatraea saccharalis, is a major target pest of transgenic corn expressing Bacillus thuringiensis (Bt) proteins in many areas of the U.S. mid-southern region. A Cry1Ab-resistant (Cry1Ab-RR) strain of D. saccharalis has been developed from a single two-parent family-line. To examine the molecular mechanisms of the Cry1Ab resistance in this insect strain, cDNAs of five types of potential candidate genes related to Bt resistance were sequenced using reverse transcriptase polymerase chain reaction (RT-PCR) and 5’ rapid amplification of cDNA end (5’ RACE). The Bt resistance candidate genes examined included three trypsins (DsTRYs), three chymotrypsins (DsCHYs), three aminopeptidases N …

Evaluation Of Species Distribution Model Algorithms For Fine-Scale Container-Breeding Mosquito Risk Prediction, C. Khatchikian, Florencia Sangermano, D. Kendell, T. Livdahl

Geography

The present work evaluates the use of species distribution model (SDM) algorithms to classify high densities of small container-breeding Aedes mosquitoes (Diptera: Culicidae) on a fine scale in the Bermuda Islands. Weekly ovitrap data collected by the Department of Health, Bermuda for the years 2006 and 2007 were used for the models. The models evaluated included the algorithms Bioclim, Domain, GARP (genetic algorithm for rule-set prediction), logistic regression and MaxEnt (maximum entropy). Models were evaluated according to performance and robustness. The area under the receiver operating characteristic curve was used to evaluate each model's performance, and robustness was assessed according …

A Taxonomic Revision Of The New World Hypoponera Santschi, 1938 (Hymenoptera: Formicidae), Shawn Thomas Dash

Open Access Theses & Dissertations

The New World taxa of the pantropic ant genus Hypoponera (Ponerinae: Ponerini) is revised for the first time. The 55 previously recognized taxa have been evaluated using morphological and, when possible, ecological and biogeographical data to resolve taxon validity and species limits. Currently I recognize 42 species of Hypoponera , a number of which are new. I propose the following taxonomic outline: Hypoponera agilis (Borgmeier), Hypoponera aliena (F. Smith), Hypoponera antoniensis (Forel) stat. nov., Hypoponera apateae sp. nov., Hypoponera capilosa sp. nov., Hypoponera clinei sp. nov., Hypoponera clavatula (Emery) [= fiebrigi (Forel) syn. nov., = neglecta (Santschi) syn. nov.], Hypoponera …
