Insects With Similar Social Complexity Show Convergent Patterns Of Adaptive Molecular Evolution, Kathleen A. Dogantzis, Brock A. Harpur, André Rodrigues, Laura Beani, Amy L. Toth, Amro Zayed

Ecology, Evolution and Organismal Biology Publications

Eusociality has independently evolved multiple times in the hymenoptera, but the patterns of adaptive molecular evolution underlying the evolution and elaboration of eusociality remain uncertain. Here, we performed a population genomics study of primitively eusocial Polistes (paper wasps), and compared their patterns of molecular evolution to two social bees; Bombus (bumblebees), and Apis (honey bees). This species triad allowed us to study molecular evolution across a gradient of social complexity (Polistes < Bombus < Apis) and compare species pairs that have similar (i.e. Polistes and Bombus) or different (i.e. Polistes and Apis) life histories, while controlling for phylogenetic distance. We ...

Risk Assessment Of Fall Armyworm Resistance To Transgenic Corn Containing Single Or Pyramided Bacillus Thuringiensis Genes, YING NIU 2018 Louisiana State University at Baton Rouge

Risk Assessment Of Fall Armyworm Resistance To Transgenic Corn Containing Single Or Pyramided Bacillus Thuringiensis Genes, Ying Niu

LSU Doctoral Dissertations

The fall armyworm, Spodoptera frugiperda (J.E. Smith), is a target pest of Bacillus thuringiensis (Bt) crops in North and South America. However, after more than two decades of the intense use of Bt crop technology, S. frugiperda has developed resistance to Bt corn in several countries. The objectives of this study were: 1) to characterize the inheritance and fitness costs of Cry1A.105 resistance in S. frugiperda; 2) to evaluate larval survival and plant injury of Cry1A.105-susceptibile, -resistant, and -heterozygous S. frugiperda populations on transgenic corn plants containing single or pyramided Bt genes; 3) to estimate the frequency ...


Susceptibility Of Field-Collected Pupations Of The Corn Earworm, Helicoverpa Zea (Boddie) (Lepidoptera: Noctuidae) From Three Southern States Of The U.S. To Cry1a.105 And Cry2ab2 Proteins, Gagandeep Kaur 2018 Louisiana State University and Agricultural and Mechanical College

Susceptibility Of Field-Collected Pupations Of The Corn Earworm, Helicoverpa Zea (Boddie) (Lepidoptera: Noctuidae) From Three Southern States Of The U.S. To Cry1a.105 And Cry2ab2 Proteins, Gagandeep Kaur

LSU Master's Theses

The corn earworm (CEW), Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), is a major target pest of pyramided Bt corn and Bt cotton in the U.S. In 2016 and 2017, notable corn ear damage and larval survival of CEW were observed on pyramided Cry1A.105/Cry2Ab2 corn in some fields in northeast Louisiana. The objectives of this study were 1) to determine if the ear damage and larval survival observed in the area were due to resistance development to the Bt proteins in the plants, and 2) if resistance had occurred, to determine the approximate distributions of the resistance in the ...


Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke 2018 Chapman University

Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Nesting birds must often cope with harassment from biting insects, but it is difficult to ascertain what effect such pests might have on breeding success and population dynamics. We tested the hypothesis that a black fly (Simulium annulus) that feeds on the blood of nesting Common Loons (Gavia immer) causes nest abandonment in this charismatic diving bird. In addition, we measured effects of fly-induced abandonment on a loon population, and examined potential predictors of fly abundance and nest abandonment. We also tested a second hypothesis, which holds that loon pairs that abandon a nest owing to flies should often remain ...

Bee viral ecology is a fascinating emerging area of research: viruses exert a range of effects on their hosts, exacerbate the impacts of other environmental stressors, and, importantly, are readily shared across multiple bee species in a community. However, our understanding of bee viral communities is limited, as it is primarily derived from studies of North American and European Apis mellifera populations. Here, we examined viruses in populations of A. mellifera and 11 other bee species from 9 countries, across 5 continents and Oceania. We developed a novel pipeline to rapidly, inexpensively, and robustly screen for bee viruses. This pipeline ...


Population Genetics And Bumble Bee Conservation: Saving Species By Thinking Small, Cady Greenslit 2018 Lawrence University

Population Genetics And Bumble Bee Conservation: Saving Species By Thinking Small, Cady Greenslit

Lawrence University Honors Projects

Pollinators have experienced a severe decline over the last few decades, and this includes bumble bee populations (g. Bombus). Bumble bees are important native pollinators, and here I investigate the health of local populations with molecular tools. The field of conservation genetics has created useful methodology for investigating the health and informing management strategies of threatened populations. This work investigates and describes the applications of population genetics, which uses span across the board. These applications are then brought back into the context of bumble bee conservation, and how they fit into the experimental plan I originally designed. I designed an ...


Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender 2018 Fordham University

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...

Population Structure, Demographic History, And Environmental Niche Of The Sand Fly Disease Vector Lutzomyia Shannoni (Dyar) (Diptera: Psychodidae) In The U.S., Mexico, And Colombia, Matthew E. Wolkoff 2018 University of Texas at Tyler

Population Structure, Demographic History, And Environmental Niche Of The Sand Fly Disease Vector Lutzomyia Shannoni (Dyar) (Diptera: Psychodidae) In The U.S., Mexico, And Colombia, Matthew E. Wolkoff

Biology Theses

Lutzomyia shannoni (Dyar, 1929) (Diptera: Psychodidae) is the only known sand fly vector of vesicular stomatitis virus, a putative leishmaniasis vector, and also boasts the widest distribution of any sand fly in the New World. Research on Lu. shannoni in Central and South America has revealed genetically divergent subpopulations; however, tentative analysis of Lu. shannoni in the U.S. has failed to detect any significant population structure, even between specimens collected from highly disparate localities.

The present study used four molecular markers to more closely investigate the population structure of Lu. shannoni in the U.S., and assess the species ...


Apicentrism In City Parks: Cultivating Honey Bee Prosperity In The Face Of Colony Collapse Disorder, John Hughes 2018 Fordham University

Apicentrism In City Parks: Cultivating Honey Bee Prosperity In The Face Of Colony Collapse Disorder, John Hughes

Student Theses 2015-Present

One of the most pertinent ecological crises of the 2010s is the frightening ambiguity of colony collapse disorder. As honey bee populations continue to be decimated in unprecedented numbers, this epidemic will exert profound effects on human populations both ecologically and economically. This thesis explores the epidemic using quantifiable and ecological information about the honey bee and pesticides. From this base, this thesis then explores pesticide use in New York City Parks in relation to the disorder. Finally, the thesis challenges readers to adopt a political and philosophical shift towards an environmental ethic that will take better care of the ...


Forensic Entomology And The Order Coleoptera, Carrie Pratt 2018 University of North Dakota

Forensic Entomology And The Order Coleoptera, Carrie Pratt

Essential Studies UNDergraduate Showcase

Medico-legal forensic entomology is the study of insects to aid in determining time, place, manner, and cause of death. Identification of the postmortem interval (PMI), or the time that has passed since a person has died, is arguably one of the most important pieces of information that forensic entomology can provide. The PMI can be found using either insect developmental rates or entomofaunal succession, the arrival of different insects at a body at different time points.

The largest group of insects, the beetles, is the order Coleoptera, which contains 25% of all animal species. Members of this order are critical ...


Seasonal Phenology, Distribution And Treatments For Polyphagotarsonemus Latus (Banks) On Primocane-Fruiting Blackberries (Rubus L. Subgenus Rubus) In Arkansas, Jessica Anne LeFors 2018 University of Arkansas, Fayetteville

Seasonal Phenology, Distribution And Treatments For Polyphagotarsonemus Latus (Banks) On Primocane-Fruiting Blackberries (Rubus L. Subgenus Rubus) In Arkansas, Jessica Anne Lefors

Theses and Dissertations

Worldwide, blackberries (Rubus L. subgenus Rubus) are an economically important crop. In 2007, Polyphagotarsonemus latus (Banks) (broad mites), were first reported damaging primocane-fruiting blackberries in Fayetteville, Arkansas. Since this time, broad mite damage to blackberries and yield loss has been reported in many states and countries. Despite the increasing reports of this blackberry pest, little is known about their population dynamics, and few treatments are available. Growers with broad mite populations need a pest management program to minimize yield loss. Therefore, there was a need to develop sampling techniques, describe broad mite seasonal phenology in blackberry fields, and determine efficacy ...


Experimental Evidence That The Non-Native European Fire Ant Alters Invertebrate Communities, Madeson C. Goodman 2018 State University of New York College at Buffalo - Buffalo State College

Experimental Evidence That The Non-Native European Fire Ant Alters Invertebrate Communities, Madeson C. Goodman

Biology Theses

Successful non-native species can reduce native species richness through both direct and indirect competition. Many invasive ants, such as the European fire ant (Myrmica rubra), are particularly successful invaders due to their ability to form multi-nest, multi-queen “supercolonies” that appear to displace native ant and non-ant invertebrate fauna in invaded regions. Myrmica rubra has invaded the Northeastern United States, including Tifft Nature Preserve in Western New York, but its seemingly negative impacts on local invertebrate communities have only been assessed using correlative studies, making it difficult to determine whether these ants directly displace native ants and invertebrates or are simply ...


Species And Cultural Management Of Earthworms On Golf Course Turf In Arkansas And Oklahoma, Paige Elizabeth Boyle 2018 University of Arkansas, Fayetteville

Species And Cultural Management Of Earthworms On Golf Course Turf In Arkansas And Oklahoma, Paige Elizabeth Boyle

Theses and Dissertations

As earthworms feed, they can egest soil and nutrient-rich aggregates (casts) on the soil surface. In low-cut turfgrass systems, such as golf course greens, tees, and fairways, surface casting can result in a muddy playing surface, ball roll issues, weed and pest invasion, reduced aesthetics, surface softening, and reduced photosynthesis. Because the use of pesticides for earthworm control is illegal in the U.S., earthworm casting must be managed through cultural practices. Sand topdressing is one method of earthworm control studied for use on golf courses, with the supposition being that the abrasive sand particles will deter the soft-bodied earthworms ...
