Diet-Mixing in a Generalist Herbivore: Trade-Offs Between Nutrient And
DIET-MIXING IN A GENERALIST HERBIVORE: TRADE-OFFS BETWEEN NUTRIENT AND ALLELOCHEMICAL REGULATION A Dissertation by MARION LE GALL Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Spencer Behmer Committee Members, Micky Eubanks Keyan Zhu-Salzman Gil Rosenthal Jon Harrison Head of Department, David Ragsdale May 2014 Major Subject: Entomology Copyright 2014 Marion Le Gall ABSTRACT Despite decades of research, many key aspects related to the physiological processes and mechanisms insect herbivores use to build themselves remain poorly understood, and we especially know very little about how interactions among nutrients and allelochemicals drive insect herbivore growth processes. Understanding the physiological effects of these interactions on generalist herbivores is a critical step to a better understanding and evaluation of the different hypothesis that have been emitted regarding the benefits of polyphagy. I used both lab and field experiments to disentangle the respective effect of protein, carbohydrates and allelochemicals on a generalist herbivore, the grasshopper Melanoplus differentialis. The effect of protein and carbohydrates alone were examined using artificial diets in choice and no-choice experiments. Results were plotted using a fitness landscape approach to evaluate how protein-carbohydrate ratio and/or concentration affected performance and consumption. Growth was best near the self-selected ratio obtained from the choice experiment, most likely due to the fact that the amount of food digested was also higher on that ratio. By contrast, development time was not best near the preferred ratio most likely due to the trade-off existing between size and development time. -

Invertebrate Distribution and Diversity Assessment at the U. S. Army Pinon Canyon Maneuver Site A report to the U. S. Army and U. S. Fish and Wildlife Service G. J. Michels, Jr., J. L. Newton, H. L. Lindon, and J. A. Brazille Texas AgriLife Research 2301 Experiment Station Road Bushland, TX 79012 2008 Report Introductory Notes The invertebrate survey in 2008 presented an interesting challenge. Extremely dry conditions prevailed throughout most of the adult activity period for the invertebrates and grass fires occurred several times throughout the summer. By visual assessment, plant resources were scarce compared to last year, with few green plants and almost no flowering plants. Eight habitats and nine sites continued to be sampled in 2008. The Ponderosa pine/ yellow indiangrass site was removed from the study after the low numbers of species and individuals collected there in 2007. All other sites from the 2007 survey were included in the 2008 survey. We also discontinued the collection of Coccinellidae in the 2008 survey, as only 98 individuals from four species were collected in 2007. Pitfall and malaise trapping were continued in the same way as the 2007 survey. Sweep net sampling was discontinued to allow time for Asilidae and Orthoptera timed surveys consisting of direct collection of individuals with a net. These surveys were conducted in the same way as the time constrained butterfly (Papilionidea and Hesperoidea) surveys, with 15-minute intervals for each taxanomic group. This was sucessful when individuals were present, but the dry summer made it difficult to assess the utility of these techniques because of overall low abundance of insects. -
1 Insects As Indicators of Habitat Quality, Ecological Integrity And
Insects as Indicators of Habitat Quality, Ecological Integrity and Restoration Success in Illinois Prairies, Savannas and Woodlands Project Number: T-92-R-1 Final Report Project Start Date: 9/1/2014 Project End Date: 7/1/2017 Sam W. Heads (Principal Investigator), Catherine E. Dana, Michael R. Jeffords, Susan L. Post, & Joseph L. Spencer Illinois Natural History Survey Prairie Research Institute, University of Illinois 1816 South Oak Street Champaign, IL 61820 1 Summary The typical methods that ecologists use for assessing habitat quality involves calculating quality based on primarily floristic data. This is true of evaluation of habitats in Illinois – although new methods have become available for assessing habitats based on other taxa. These alternative methods are often not in widespread use, especially in Illinois, and consist of using invertebrate indicator taxa to assess the ecological integrity of prairies, savannas, and woodlands (aquatic invertebrate survey tend to be more commonly used). There is a large diversity of invertebrates for which we have information on the life history, seasonality, and diet that live in these unique habitats. Critically, these organisms are often sensitive to environmental change and habitat fragmentation. Insects in particular can thus be valuable indicators of habitat quality and ecosystem integrity. For this study, we chose to look at four groups of insects as indicators, based on their life history, ease of identification, and knowledge of the co-authors. These groups are well represented in grassland biomes and include: (1) grasshoppers (Orthoptera: Acridoidea); (2) butterflies (Lepidoptera: Rhopalocera); (3) cicadas (Hemiptera: Cicadoidea); and (4) tiger beetles (Coleoptera: Carabidae). By looking at both the abundance and species diversity at a given site for each of these groups, we hoped to develop tools that would allow land managers to utilize these taxa as indicators of high quality prairie. -

Cerro de las Campanas, Querétaro, México. 2Department of Agroecology, Colegio de la Frontera Sur, San Cristóbal de las Casas, Chiapas, México. Accepted 16 December, 2011 Acridoidea is a superfamily within the Orthoptera order that comprises a group of short-horned insects commonly called grasshoppers. Grasshopper and locust species are major pests of grasslands and crops in all continents except Antarctica. Economically and historically, locusts and grasshoppers are two of the most destructive agricultural pests. The most important locust species belong to the genus Schistocerca and populate America, Africa, and Asia. Some grasshoppers considered to be important pests are the Melanoplus species, Camnula pellucida in North America, Brachystola magna and Sphenarium purpurascens in northern and central Mexico, and Oedaleus senegalensis and Zonocerus variegatus in Africa. Previous studies have classified these species based on specific characteristics. This review includes six headings. The first discusses the main species of grasshoppers and locusts; the second focuses on their worldwide distribution; the third describes their biology and life cycle; the fourth refers to climatic factors that facilitate the development of grasshoppers and locusts; the fifth discusses the action or reaction of grasshoppers and locusts to external or internal stimuli and the sixth refers to elements to design management strategies with emphasis on prevention. -

BARNUM- Grand Junction, Colorado INTRODUCTION During the years of 1950 to 1952 a study of the taxonomy and distribution of the Utah Orthoptera was made at the Brigham Young University by the author under the direction of Dr. Vasco M. Tan- ner. This resulted in a listing of the species found in the State. Taxonomic keys were made and compiled covering these species. Distributional notes where available were made with the brief des- criptions of the species. The work was based on the material in the entomological col- lection of the Brigham Young University, with additional records obtained from the collection of the Utah State Agricultural College. -
Kentucky CCA Performance Objectives
CERTIFIED CROP ADVISER Performance Objectives for Kentucky (SW Revised 2006) INTRODUCTION The International Certified Crop Adviser (ICCA) program is coordinated by the American Society of Agronomy. State or regional boards administer the CCA program in each state, province, or region, respectively. The Kentucky CCA Board is responsible for developing state-specific performance objectives and the Kentucky CCA exam. This performance objectives booklet outlines the knowledge and skills that the Kentucky CCA Board believes all Certified Crop Advisers practicing in Kentucky should possess. The booklet, thus, is useful in determining areas of expertise that may be covered in the Kentucky CCA exam. The booklet is divided into four sections: (1) Nutrient Management; (2) Soil and Water Management; (3) Integrated Pest Management; and (4) Cropping Systems Management. Each section is further divided into competency areas and specific performance objectives within each competency area. Sections are updated periodically to keep the Kentucky CCA program in step with changing trends and technology. The latest revisions were: Nutrient Management—2005; Soil and Water Management—2006; Integrated Pest Management—2004; Cropping Systems Management—2004. Integrated Pest Management is scheduled to be revised in 2007. The main rationale for having a state-specific CCA program and performance objectives is to address practices and situations that are not covered by the ICCA exam and performance objectives. The booklet covers the most important non-horticultural crops grown in Kentucky. These include: Corn for grain and silage Forage grasses and legumes Soybean Tobacco Small Grains To the user of this booklet: Please send any corrections, suggestions, or comments to: Kenneth L. -

Effects of Livestock Grazing on Aboveground Insect Communities In
Biodiversity and Conservation (2006) 15:2547–2564 Ó Springer 2006 DOI 10.1007/s10531-005-2786-9 -1 Effects of livestock grazing on aboveground insect communities in semi-arid grasslands of southeastern Arizona SANDRA J. DEBANO Department of Entomology, University of Kentucky, Lexington, Kentucky 40546-0091, USA; Present address: Department of Fisheries and Wildlife, Oregon State University, Hermiston Agricultural Research and Extension Center, P.O. Box 105, Hermiston, Oregon 97838-7100, USA (e-mail: [email protected]; phone: +001-541-567-6337; fax: +001-541-567-2240) Received 22 June 2004; accepted in revised form 14 February 2005 Key words: Arizona, Grasslands, Insect communities, Insect conservation, Livestock grazing Abstract. Despite the importance of invertebrates in grassland ecosystems, few studies have examined how grassland invertebrates have been impacted by disturbances in the southwestern United States. These grasslands may be particularly sensitive to one common disturbance, livestock grazing, because they have not recently evolved in the presence of large herds of bison, an important mammalian herbivore. This study examined how livestock grazing influenced vegetation- associated insect communities in southeastern Arizona. Insect abundance, richness, diversity, community composition, and key environmental variables were compared between sites on active cattle ranches and sites on a 3160 ha sanctuary that has not been grazed by cattle for over 25 years. Vegetation-associated insect communities were found to be sensitive to livestock grazing. Overall abundance of these insects was lower on grazed grasslands, and certain insect orders appeared to be negatively affected by livestock grazing; beetles were less rich, flies were less diverse, and Hymenoptera were less rich and diverse on grazed sites. -
