Competition And Intraguild Predation Between Beetles, Pterostichus Stygicus (Coleoptera: Carabidae) And Centipedes, Scolopocryptops Sexspinosus (Scolopemdromorpha: Scolopocryptopidae), Michele E. Julian, Cari-Ann M. Hickerson, Carl Anthony

2019 Faculty Bibliography

Studying interactions between distantly related species is necessary to understand the complexity of food webs. Generalist predator interactions, such as intraguild predation (IGP) and competition, can alleviate predation pressure and weaken top–down control that predators have on lower trophic levels. Centipedes (Chilopoda) and carabid beetles (Coleoptera) are common deciduous forest floor generalist predators that may interact by competing for resources beneath rocks and logs on the forest floor, especially during dry periods when prey become confined to such microhabitats. We used laboratory and field studies to determine whether the carabid beetle, Pterostichus stygicus (Say), and the centipede, Scolopocryptops sexspinosus (Say) …

Integrated Pest Management Manual For Greenhouses, Evy Z. Santiago

Department of Entomology: Distance Master of Science Projects

The original definition of Integrated Pest Management (IPM) was introduced by Stern et al. in 1959 as Integrated Control. It was defined as applied pest control which combines and integrates biological and chemical control (Stern et al. 1959). Entomologists began exploring insect management alternatives to reduce reliance on insecticides in the 1950’s after resistance and pest resurgence in agriculture was first noted. Today, the European Union follows a definition of IPM largely inspired from the definition given by the Food and Agriculture Organization of the United Nations (FAO) (Barzman et al. 2015). Integrated Pest Management means the careful consideration of …

Using Insects To Improve Seed Quality And Farming Profitability In Phaseolus Vulgaris, Eduardo Valentín Cruzado

Department of Entomology: Distance Master of Science Projects

Phaseolus vulgaris, or dry beans, are generally cultivated for their seeds, which add flavor to the diets of millions of people throughout the world. This crop was originally domesticated in South America more than 7,000 years ago, eventually spreading north through Mexico and across most of the United States (NDBGA, n.d.). Phaseolus vulgaris belongs to the legume family, and like other legumes it can fix nitrogen in the soil from the air through a symbiotic relationship with a bacterium called Rhizobia. In addition to this, P. vulgaris is high in protein, and in many parts of the world, it …

Eucosma Giganteana (Riley) And Sliphium Perfoliatum L., Morphological Variation In An Insect-Plant Association In Eastern South Dakota, Paul J. Johnson, Arvid Boe, Abigail P. Martens

Native Plant Focused Publications

Silphium perfoliatum L., cup plant, has potential as a new multi-purpose crop. It is pollinator-friendly and has biodiversity enhancement, conservation, economic, and medical potential. In eastern South Dakota, S. perfoliatum can produce more than 20 Mg (million grams) ha-1 of biomass and 0.09 Mg ha-1 of seed in agronomic plantings. The giant eucosma moth, Eucosma giganteana (Riley), is a major pest of agronomic S. perfoliatum in the region. We provide a summary of this insect and its association with its host. Our experimental objectives were to determine if the frequency of rhizome occupation by late instar larvae and if their …

Inferring Food Web Structure To Identify Seasonal And Longitudinal Patterns In Ogeechee River Invertebrate Communities, Julien Marc Buchbinder

College of Graduate Studies: Theses & Dissertations

Understanding how the structure and function of aquatic communities vary across space and time is essential for proper management of freshwater ecosystems. Current management relies on rapid biomonitoring using metrics of community structure, but metrics that incorporate ecosystem processes and functions are only just beginning to see use in assessment and management. Food webs inferred from known species interactions have been proposed as a method of incorporating function into bioassessment without expending extra effort or sacrificing the cost-effectiveness of current monitoring schemes. To apply food webs in biomonitoring, it is first necessary to understand how communities and food webs vary …

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines

Lewis Honors College Capstone Collection

Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim …

The Economics Of Honey Bee (Hymenoptera: Apidae) Management And Overwintering Strategies For Colonies Used To Pollinate Almonds, Gloria Degrandi-Hoffman, Henry Graham, Fabiana Ahumada, Matthew Smart, Nick Ziolkowski

Department of Entomology: Faculty Publications

Commercial honey bee (Apis mellifera L.) colonies significantly contribute to agricultural productivity through crop pollination. Almond production requires the most colonies because there are more than a million acres of orchards that require cross-pollination for nut set. With the rising costs of managing and transporting colonies to almond orchards combined with the high colony losses beekeepers routinely experience, we asked if renting colonies for almond pollination was profitable. We conducted a longitudinal study on 190 colonies from their establishment in April until they were placed in almond orchards 10 mo later. In the fall, equal numbers of colonies were placed …

External Marking And Behavior Of Early Instar Helicoverpa Armigera (Lepidoptera: Noctuidae) On Soybean, Luiz E. R. Pannuti, Edson L. L. Baldin, Silvana L. Vieira De Paula Moraes, Thomas E. Hunt, Vinicius F. Canassa, José P. F. Bentivenha, Ivana F. Da Silva

Department of Entomology: Faculty Publications

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is a pest of major agricultural crops, such as soybean and cotton. A better understanding of larval movement is important for its integrated management and resistance management. Studies with neonates through second instar larvae are still limited by the difficulties involving the handling and observation of these instars. Many studies require marking larvae, and most research involving marking is focused on moths. However, our study investigated aspects of larval behavior of the second instar of H. armigera on soybean plants. The dyes luminous powder red and Sudan Red 7B were tested as external larval …

Developmental Parameters Of Spodoptera Frugiperda (Lepidoptera: Noctuidae) Immature Stages Under Controlled And Standardized Conditions, Débora Goulart Montezano, Alexandre Specht, Daniel Ricardo Sosa-Gomez, Vânia Ferreira Roque-Specht, Silvana L. Vieira De Paula Moraes, Julie A. Peterson, Thomas E. Hunt

Department of Entomology: Faculty Publications

The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797), is the most important noctuid pest in the Americas and has recently become an invasive pest in Africa and in India. Having a detailed and standardized record of the biology and the larval development of S. frugiperda will be critical to further studies on integrated pest management, toxicology, and applied ecology. This study reports the temporal and morphological parameters of the immature stages of S. frugiperda for larvae fed on artificial diet under controlled conditions (25 ± 1 °C, 70 ± 10% RH and 14 hour photophase). The survival …

New Tribes, Overview And Checklist Of Neotropical Cladonotinae (Orthoptera: Caelifera: Tetrigidae), Daniela Santos Martins Silva, Oscar J. Cadena-Castañeda, Marcelo Ribeiro Pereira, Fernando Campos De Domenico, Carlos Frankl Sperber

Insecta Mundi

The Cladonotinae (Orthoptera: Caelifera: Tetrigidae) are a peculiar tetrigid taxon characterized by a relatively widened fascial carina on the frontal costa. This group currently has a doubtful taxonomic status since this is the only character shared by its members. Here, we provide an overview of the Cladonotinae reported from the Neotropical region (29 species, three of them fossils), based on the morphological examination of the specimens housed at several museums. We show that Neotropical Cladonotinae share more characteristics, which strengthen its taxonomic status, and propose two new tribes: Choriphyllini n. trib. and Mucrotettigini n. trib. We propose the new combination …
