Bean Leaf Beetle And Soybean Aphid Control Using Foliar Treatments In A Certified-Organic Operation—Neely-Kinyon Trial, 2010-2011, Andrea Mckern

Department of Entomology: Distance Master of Science Projects

Summary of Project

Goal: The goal of this project is to find effective management treatments for the bean leaf beetle (Cerotoma trifurcata) and soybean aphid (Aphis glycines) for use in certified-organic soybeans. The bean leaf beetle is one of the major vectors of bean pod mottle virus, which causes seed staining and can cause a downgrading of the soybeans at market from food grade to feed grade. Feeding from the soybean aphid causes stunted plants, reduced pods and seeds, and can transmit viruses that cause mottling and distortion of the leaves and a reduced seed set. …

Mosquito Species Abundance And Diversity In Malindi, Kenya And Their Potential Implication In Pathogen Transmission, Joseph M. Mwangangi, Janet Midega, Samuel Kahindi, Laban Njoroge, Joseph Nzovu, John Githure, Charles M. Mbogo, John C. Beier

All Peer-Reviewed Publications

Mosquitoes (Diptera: Culicidae) are important vectors of human disease-causing pathogens. Mosquitoes are found both in rural and urban areas. Deteriorating infrastructure, poor access to health, water and sanitation services, increasing population density, and widespread poverty contribute to conditions that modify the environment, which directly influences the risk of disease within the urban and peri-urban ecosystem. The objective of this study was to evaluate the mosquito vector abundance and diversity in urban, peri-urban, and rural strata inMalindi along the Kenya coast. The study was conducted in the coastal district of Malindi between January and December 2005. Three strata were selected which …

Invertebrate Abundances And Diversity Of A Six Year Old Organic Apple Orchard In Northwest Arkansas, Cory Johnson, Brina Smith, Mary C. Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Ground cover mulch applications in perennial systems can have multiple benefits, one of which may be to enhance the size and diversity of the ground surface faunal community. To determine if ground cover and organic fertilizer applications altered invertebrate communities, litters in an experimental 0.4-ha organic apple orchard in Fayetteville, Ark. were sampled during a four week period beginning in February 2012. The orchard was planted in 2006 in a replicated 4 × 3 factorial design with organic ground cover and fertilizer treatments applied annually each April. Invertebrates were extracted using Berlese funnels and hand sorting techniques. Ground covers (wood …

Molecular Characterization And Tissue-Specific Gene Expression Of Dermacentor Variabilis Α-Catenin In Response To Rickettsial Infection, Piyanate Sunyakumthorn, Natthida Petchampai, Michael T. Kearney, Daniel E. Sonenshine, Kevin R. Macaluso

Biological Sciences Faculty Publications

Alpha catenin is a cytoskeleton protein that acts as a regulator of actin rearrangement by forming an E-cadherin adhesion complex. In Dermacentor variabilis, a putative α-catenin (Dvα-catenin) was previously identified as differentially regulated in ovaries of ticks chronically infected with Rickettsia montanensis. To begin characterizing the role(s) of Dvα-catenin during rickettsial infection, the full-length Dvα-catenin cDNA was cloned and analysed. Comparative sequence analysis demonstrates a 3069-bp cDNA with a 2718-bp open reading frame with a sequence similar to Ixodes scapularis α-catenin. A portion of Dvα-catenin is homologous to the vinculin-conserved domain containing a putative …

Aspen, Important Pests Of Ornamental Spen, Fred A. Baker, Diane G. Alston, Claudia Nischwitz

All Current Publications

Aspens are one of the more popular forest trees in the Intermountain West. They add a brilliant yellow glow to the collage of fall colors. In an attempt to enjoy these beautiful trees around the home environment, many well-intentioned homeowners purchase or otherwise acquire aspens and transplant them into their landscapes. Unfortunately, aspens are not adapted to the environmental conditions of the valleys, and many problems develop.

Spotted Wing Drosophila Monitoring, Cory A. Stanley

All Current Publications

Spotted wing drosophila (SWD) (Drosophila suzukii) is a new fruit pest first introduced to the United States in 2008. SWD was detected in Davis County, Utah in 2010. SWD is similar to other vinegar flies (genus Drosophila), except they can infest unripe fruit.

Utah Home Orchard Pest Management Guide, Marion Murray, Diane Alston, Claudia Nischwitz

Integrated pest management (IPM) is the practice of combining knowledge of the pest and host plant with multiple tactics for long-term, safe pest control. The goal of IPM is pesticide reduction by using cultural, mechanical, and biological controls before the last option, pesticides.

Effects Of Methoprene On The Survivorship Of Adult Aedes Mosquitoes: A Strategy Or Inactivating Released Mosquitoes, Peter J. Brabant Iii

Theses and Dissertations--Entomology

Methoprene is a Juvenile Hormone (JH) analogue commonly used for the control of mosquito larvae. When applied to a mosquito breeding site, methoprene enters the haemolymph, where it mimics the function of JH and interferes with normal metamorphosis, resulting in larval mortality. Methoprene is commonly used for the control of larvae and has not been used as an adulticide, due to an absence of acute effects. This study evaluated possible chronic effects caused by the exposure of adult Aedes mosquitoes to methoprene. Methoprene was applied, in both technical grade and the commercially available Altosid®, topically to adults through droplet application …

Integrated Management Of The Red Imported Fire Ant In Pastures, William Sullivan Hilbun

LSU Master's Theses

The effects and interactions of chemical, cultural, and biological control of red imported fire ant (RIFA) populations were evaluated in two replicated studies in pastures. The first study was conducted from 2005 through 2007 in Washington parish, Louisiana (WP) where the biological control Psuedacteon tricupsis phorid flies were present and at the LSU AgCenter St. Gabriel Research Station in St. Gabriel, Louisiana (SG) where Psuedacteon tricuspis flies were absent. The second study was conducted from May 2009 to May 2010 at St. Gabriel in the presence of phorid flies. In both studies, RIFA population indices in sites treated with methoprene …

Enabling Learning And Enhancing Education In Ipm In The Midst Of Dwindling Financial Resources: Why Open Access To Resources And Publishing Could Be A Strategic Step To Support Students Today And Tomorrow?, Ousmane Youm

Department of Entomology: Faculty Publications

When I was invited to join the editorial board of the journal Entomology, Ornithology & Herpetology (EOH), I read carefully the note coming with the invitation and also looked at the content and scope. Then two things came into my mind as I stopped a few minutes to reflect on a couple of issues: (1) how the new journal links and is relevant to Integrated Pest Management—IPM (for those who understand its definition)—and (2) the issue of open access and relevance in the current situation of an ailing global economy, particularly in the vulnerable developing nations.

In the latter, more …

A Review Of The Distribution Of Harposcelis Paradoxus Burmeister, 1847 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) With A New Country Record For Peru, Jochen-P. Saltin, Brett C. Ratcliffe

Department of Entomology: Faculty Publications

Harposcelis paradoxus Burmeister is a relatively rare lowland species that, for a long time, was known only from French Guiana (Blackwelder 1944; Endrödi 1966, 1985; Krajcik 2005). Males are more commonly collected than females and are now commonly available via the Internet from commercial dealers in the insect trade. At a body length of 40 mm, this is a remarkably large species for a member of the tribe Cyclocephalini. Males are distinctive because of their long, curved protibiae and anterior trochanter with a large, anteriorly projecting tooth. The genus can be identified in keys by Endrödi (1966, 1985), Ratcliffe (1985), …

Breeding Biology And Bee Guild Of Douglas’ Dustymaiden, Chaenactis Douglasii (Asteraceae, Helenieae), James H. Cane, Byron Love, Katharine A. Swoboda-Bhattarai

Department of Entomology: Faculty Publications

Douglas’ dustymaiden, Chaenactis douglasii (Hook.) Hook. & Arn., is a widespread, inconspicuous, short-lived perennial wildflower that blooms in early summer and is found in basin sagesteppe to upper montane areas throughout the U.S. Intermountain West. The species is proving practical to grow for seed and is expected to be used for western rangeland rehabilitation. Through manual pollination experiments, C. douglasii was found to be only weakly self-fertile; 15% of flowers from geitonogamy and autogamy treatments yielded filled achenes. In contrast, 57% of outcrossed flowers produced achenes filled with endosperm, with every capitulum yielding some fertile seeds. Freely visited flowers from …
