The Ants (Hymenoptera: Formicidae) of Alabama
(2008-09-09)
This thesis presents the first statewide survey of the ant fauna of Alabama in over seventy years. Since the first state survey by L.C. Murphree (in the 1930’s) to present, 154 species have been reported. Fifty-nine of the ...
Chemical Ecology and Management of Yellowmargined Leafbeetle Microtheca ochroloma Stal (Coleoptera: Chrysomelidae)
(2011-08-22)
Cruciferous vegetable production is an important industry in Alabama and other parts of the southern United States (U.S.). Many farmers in the region grow various kinds of cruciferous crops (e.g., turnip, radish, mustard, ...
Recruitment to and Defense of Aphids by Fire Ants and Native Ants and an Estimate of Their Trophic Positions Using Stable Isotopes
(2009-02-23)
The red imported fire ant, Solenopsis invicta, is an invasive ant known to form facultative mutualisms with aphids. Fire ants significantly reduce the abundance of aphid predators and herbivores on plants infested with ...
Molecular Mechanisms of Cytochrome P450 Monooxygenase-Mediated Pyrethroid Resistance in the House Fly, Musca domestica (L.)
(2009-02-23)
A wild-type pyrethroid resistant house fly strain, ALHF, was collected from a poultry farm in Alabama after control failure with permethrin (a pyrethroid insecticide). It was further selected with permethrin for 6 generations ...
Molecular Mechanisms of Pyrethroid Resistance in the Mosquito, Culex quinquefasciatus (Say)
(2009-02-23)
Mosquitoes have been the ideal transmitters of a wide variety of disease agents due to their repeated blood feedings over their life span. Culex quinquefasciatus (Say) is an important disease vector in the Southeastern ...
Mutualisms, Commensalisms, and Predation: The Direct and Indirect Effects of Fire Ants on Arthropods and Plants
(2009-02-23)
The red imported fire ant, Solenopsis invicta, is a voracious generalist predator that has dramatically affected the native arthropod community since its introduction approximately 75 years ago. Most research suggests S. ...
Developing Alternatives to Methyl Bromide: A Focus on Acrolein (2-Propenal)
(2008-09-09)
Methyl bromide, a soil fumigant with biocidal action, is used in agriculture to control weeds, fungi, bacteria, nematodes, and arthropods. Due to methyl bromide’s active role in atmospheric ozone depletion, its usage will ...
Studies on the Biology and Host Location Behavior of Pteromalus cerealellae (Ashmead) (Hymenoptera: Pteromalidae), A Parasitoid of Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae)
(2008-09-09)
Pteromalus cerealellae is an ectoparasitoid of several pests of stored products. Information on several aspects of its biology and life history strategy is grossly lacking. My dissertation focuses on some aspects of the ...
Identification of Plant-Parasitic Nematodes Using FAME Analysis
(2009-07-22)
For several years, chromatographic analysis of fatty acid methyl esters (FAME) has been used to identify bacteria more quickly than traditional methods. The objective of this study was to determine the applicability of ...
The Effect of Cover Crops on Suppression of Nematodes on Peanuts and Cotton in Alabama
(2009-02-23)
Cover crops were evaluated in the greenhouse and in field locations to determine their host status and nematode suppressive effect on root-knot nematodes, Meloidogyne incognita and M. arenaria and the reniform nematode, ...
