The Milliped Order Glomeridesmida (Diplopoda: Pentazonia: Limacomorpha) In Oceania, The East Indies, And Southeastern Asia; First Records From Palau, The Philippines, Vanuatu, New Britain, The Island Of New Guinea, Cambodia, Thailand, And Borneo And Sulawesi, Indonesia, Rowland M. Shelley

Insecta Mundi

The taxonomically neglected milliped order Glomeridesmida and family Glomeridesmidae (infraclass Pentazonia, superorder Limacomorpha) inhabit 21, rather than seven, regions of the world, being newly recorded from Thailand; Cambodia; the Republics of Palau, the Philippines, and Vanuatu; New Britain, Bismarck Archipelago; the Island of New Guinea (both West Papua [formerly Irian Jaya], Indonesia, and Papua New Guinea); and Sulawesi and Borneo, Indonesia. Occurrence in Fiji is confirmed with two additional samples, and discovery is predicted in southern China, Myanmar, and perhaps Madagascar. Coupled with published localities, these records suggest subcontinuous (super)ordinal and familial ranges extending some 12,480 km (7,800 mi) southeastward …

Ecology And Management Of The Woolly Whitefly (Hemiptera: Aleyrodidae), A New Invasive Citrus Pest In Ethiopia, Difabachew K. Belay, Abebe Zewdu, John E. Foster

Department of Entomology: Faculty Publications

Distribution and importance of woolly whitefly (Aleurothrixus floccosus) (Maskell) (Hemiptera: Aleyrodidae), was studied in Ethiopia with an evaluation of treatments against it. Results showed that the pest is distributed in most citrus-growing parts of the country equally infesting all types of citrus crops. Only one pupal parasitoid, Amitus sp., was recorded at Melkaoba. During 2006–2007, eight treatments gave better control of woolly whitefly compared with the control: endod (Phytolacca dodecandra L’Herit) berry extract, white oil 80%, neem oil, omo detergent soap, band application of gasoline, cyhalothrin (karate) 5% EC, selecron (profenofos) 500 EC, and rimon (novaluron) 10 EC. …

Genetic Variability Of The Stable Fly, Stomoxys Calcitrans (L.) (Diptera: Muscidae) Assessed On A Global Scale Using Amplified Fragment Length Polymorphism, Kathleen M. Kneeland

Department of Entomology: Dissertations, Theses, and Student Research

The stable fly, Stomoxys calcitrans, is a cosmopolitan pest of livestock and humans. It is a major pest in livestock facilities, where exist excellent breeding sites such as spilled feed mixed with manure. The pestiferous nature and painful bite cause stress to cattle and other animals. Cattle perform avoidance behaviors such as bunching together, standing in water, tail swishing, ear flicking and leg stamping. The stress and avoidance behaviors result in reductions in weight gain or milk production, with an estimated annual economic loss of > $1billion. Therefore, the development of more efficient control methods would benefit the global economy, …

Population Genetics Of The Western Bean Cutworm (Striacosta Albicosta Smith) Across The United States, Erica Lindroth

Department of Entomology: Dissertations, Theses, and Student Research

The western bean cutworm, Striacosta albicosta (Smith), is a secondary pest of maize (Zea mays L.) and dry beans (Phaseolus vulgaris L.) in the western United States. Recently, this insect has undergone a major territory expansion into the eastern US and has become a pest throughout much of the Corn Belt. This study was instigated to examine the population genetics of this pest to facilitate control and resistance management, as well as to shed light on the current habitat expansion. To this end, western bean cutworm individuals were collected from 28 different locations across the traditional and expanded …

Genetic Variability And Gene Flow Of The Fall Armyworm Spodoptera Frugiperda (J.E. Smith) In The Western Hemisphere And Susceptibility To Insecticides, Difabachew B. Kondidie

Department of Entomology: Dissertations, Theses, and Student Research

The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is an economically important pest of maize, sorghum, cotton, and rice in the Western Hemisphere. Previous studies on genetic diversity of FAW focused on identification of the corn and rice host strains; there is limited information about geographic genetic variation. To bridge this gap, I investigated the genetic diversity of FAW using representative samples from the United States, Argentina, Panama, and Puerto Rico with amplified fragment length polymorphism (AFLP). This study also investigated the susceptibility of the Puerto Rico FAW population to ten different insecticides used by Dow AgroSciences …
