Transmission Of Triticum Mosaic Virus And Its Impact On The Biology Of The Wheat Curl Mite Aceria Tosichella Keifer (Eriophyidae), And An Evaluation Of Management Tactics For The Wheat Curl Mite And The Wheat-Mite-Virus Complex, Anthony J. Mcmechan

Department of Entomology: Dissertations, Theses, and Student Research

The wheat-mite-virus complex is an important production constraint to winter wheat production in the Great Plains, and consists of three viruses; wheat streak mosaic (WSMV), wheat mosaic (WMoV) and Triticum mosaic virus (TriMV). Synergistic interactions between these viruses have resulted in increased rates of replication and transmission of viruses, thus increasing the potential impact on wheat yields. The wheat curl mite (WCM), Aceria tosichella Keifer is the only known vector of the viruses within the wheat-mite-virus complex.

Currently, three colonies of WCM have been characterized by differential responses to mite resistant genes (biotypes) in wheat and differential transmission of WMoV. …

BACKGROUND: Tomato yellow leaf curl virus (TYLCV) was introduced into China in 2006, approximately 10 years after the introduction of an invasive whitefly, Bemisia tabaci (Genn.) B biotype. Even so the distribution and prevalence of TYLCV remained limited, and the economic damage was minimal. Following the introduction of Q biotype into China in 2003, the prevalence and spread of TYLCV started to accelerate. This has lead to the hypothesis that the two biotypes might not be equally competent vectors of TYLCV.

METHODOLOGY/PRINCIPAL FINDINGS: The infection frequency of TYLCV in the field-collected B. tabaci populations was investigated, the acquisition and transmission …

Centipedes And Millipeds (Arthropoda: Diplopoda, Chilopoda) From Saba Island, Lesser Antilles, And A Consolidation Of Major References On The Myriapod Fauna Of “Lesser” Caribbean Islands, Rowland M. Shelley, Derek S. Sikes

Insecta Mundi

The chilopod, Cryptops hortensis (Donovan, 1810) (Scolopendromorpha: Cryptopidae), and the diplopods, Pseudospirobolellus avernus (Butler, 1876) (Spirobolida: Pseudospirobolellidae) and Oxidus gracilis (C. L. Koch, 1847) (Polydesmida: Paradoxosomatidae), are newly recorded from Saba Island, Lesser Antilles, which also harbors one additional scolopendromorph and four more chilognath millipeds. Except for the plausibly native scolopendrid centipede, Scolopendra alternans Leach, 1813, all are human introductions. Concentrated sampling is needed in the cloud/elfin forest atop Mt. Scenery, where indigenous millipeds may reside, and with extraction techniques throughout the island, to potentially document the diplopod subclass Penicillata. Nine small Caribbean islands in addition to Saba have been …

Sensory Morphology And Chemical Ecology Of The Stable Fly, Stomoxys Calcitrans: Host-Seeking And Ovipositional Selection, Khanobporn Tangtrakulwanich

Department of Entomology: Dissertations, Theses, and Student Research

Stable flies cause stress and discomfort to cattle, and other mammals, including humans and pets. Economic losses from stable flies to the U.S. cattle industry from loss of milk production and cattle weight gain exceed $2 billion annually.

Traditional stable fly management employing sanitation and insecticides is costly and often fails to provide acceptable levels of control. A novel method for managing stable flies involves the use of attractants and repellents. This approach could be used to enhance the current level of stable fly control and ultimately be incorporated into a sustainable stable fly management program.

Gravid females’ stable flies …

Ecology Of Tenodera Sinensis And Tenodera Angustipennis (Mantodea: Mantidae) In Eastern Virginia, Cory A. Gall

Biological Sciences Theses & Dissertations

My study, conducted on the Wildlife Refuge located on Virginia's Eastern Shore, focused on the life history, ecology, and intra- and interspecies interaction of Tenodera sinensis and T. angustipennis. Field methods included capture-mark-recapture, species, sex, and developmental life stage identification, and recorded key developmental milestones. Also, to analyze food-limiting growth, a laboratory cohort was fed ad lib, with lab and field cohorts measured bi-weekly and their mean weekly growth was compared.

When compared to a lab cohort, Tsinensis field mantises were shown not to be growth limited by the abundance of prey. In 2011, the dates of several developmental stages …

Parochlus Kiefferi (Garrett, 1925) In Nebraska (Diptera: Chironomidae), Barbara Hayford

Great Plains Research: A Journal of Natural and Social Sciences

A rare species of nonbiting aquatic midge, Parochlus kiefferi (Garrett, 1925), was discovered in Squaw Creek in the Pine Ridge of northwest Nebraska. Parochlus is a genus of midge found throughout the Southern Hemisphere and is only represented by this one species in the Northern Hemisphere. The typical North American species distribution of P. kiefferi includes high alpine and northern latitude streams, so the collection of P. kiefferi from a low elevation and low-latitude stream in Nebraska represents a range extension for the species. A survey for P. kiefferi from 83 samples from 53 stream sites in northern Nebraska yielded …

Rapid Molecular Species Identification Of A Morphologically Cryptic Apple Pest., Emily Green

WWU Honors College Senior Projects

Effective management of agricultural pests depends upon accurate identification of those pests. In Washington State, identification of the apple maggot, Rhagoletis pomonella, is hindered by the presence of Rhagoletis zephyria, a morphologically almost identical species. Using real-time polymerase chain reaction (qPCR), I identified three markers which differ in allele frequency between the two populations. Using these markers and the software NewHybrids, I was able to identify pure R. pomonella, R. zephyria, and hybrid flies collected from apple, snowberry, and blackhaw fruit in Bellingham, WA, and flies collected from blackhaw in central Washington. Modeling reveals that NewHybrids is able to distinguish …
