Dimensional Movement of Rotylenchulus reniformis Through a Silt Loam: Observations of Movement and Population Growth from an Initial Point of Inoculation
(2009-11-20)
Rotylenchulus reniformis was evaluated for total distance moved, rate of movement, and population growth upon initial introduction into a cotton (Gossypium hirsutum) field under irrigated and non-irrigated conditions. The ...
Identification of Pseudomonas aeruginosa Mutants Unable to Convert Ricinoleic Acid into 7,10,12-Trihydroxy-8(e)-Octadecenoic Acid (TOD) and a Survey of the Biological Activity Of TOD
(2009-04-15)
Rice blast, caused by Magnaporthe grisea, is a devastating problem in all rice producing areas of the world and is extremely difficult to prevent and/or to control. Therefore, it is critical to develop new methods to ...
Biological Control Studies on the Reniform nematode (Rotylenchulus reniformis) on Cotton in Alabama.
(2009-11-11)
Cotton production in the Southeastern United States is limited by the reniform nematode (Rotylenchulus reniformis) causing an estimated loss of $98,000.000 per year. Currently, management is based on crop rotation and use ...
Distribution and Population Dynamics of the Asian Cockroach (Blattella asahinia Mizukubo) in Southern Alabama and Georgia
(2008-09-09)
In 1986, a new species of cockroach, the Asian cockroach, Blattella asahinai Mizukubo, was introduced into Florida. The Asian cockroach is very similar in appearance to the German cockroach, B. germanica (L.), but differs ...
Harnessing the Capacity of PGPR With or Without AMF for Improved Plant Use Efficiency of Chemical Fertilizers and Organic Manure
(2009-02-23)
The basis for the application of fertilizers (manure and chemical) is to make up for soil nutrient deficiencies and maintain soil fertility towards improved crop yield. Fertilizers could exacerbate environmental problems ...
Effects of Toxicants, Temperature, and Resistance on Metabolism and Gas Exchange Patterns of the Beet Armyworm, Spodoptera exigua (Hübner), and the German Cockroach, Blattella germanica (Linnaeus)
(2008-09-09)
Components of the respiratory physiology and water relations of Bacillus thuringiensis Cry1C resistant and susceptible beet armyworms, Spodoptera exigua, and pyrethroid resistant and susceptible German cockroaches, Blattella ...
Comparative Study of Gravid-Trap Infusions for Capturing Blood-Fed Mosquitoes (Diptera: Culicidae) of the Genera Aedes, Ochlerotatus, and Culex
(2008-09-09)
Field experiments were conducted in east-central Alabama to compare the attractiveness of selected gravid-trap infusions to ovipositing female mosquitoes of 3 medically important genera: Aedes, Ochlerotatus and Culex. ...
Induction of Growth Promotion and Stress Tolerance in Arabidopsis and Tomato by Plant Growth-Promoting Rhizobacteria
(2008-09-09)
Plant growth-promoting rhizobacteria (PGPR) were evaluated for induction of growth promotion in Arabidopsis and enhancement of stress tolerance in tomato under greenhouse and field conditions. Bacillus strain GB03 not only ...
Consequences of Mutualisms Between Aphids and an Invasive Ant to Arthropod Communities and Their Host Plants
(2008-09-09)
Mutualisms between ants and honeydew-producing Hemipteran insects (e.g., aphids) are abundant and widespread in arthropod food webs, yet their ecological consequences are very poorly known. Previous work in several ...
Phenology, Natural Enemies, and Management of Lepidopteran Pests of Cole Crops in Alabama
(2008-09-09)
This thesis first looks at the seasonal abundance of the three key pests of cole crops, Plutella xylostella (L.) (Lepidoptera: Plutellidae), diamondback moth; Trichoplusia ni (Hübner) (Lepidoptera: Plutellidae), cabbage ...
