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. ...
Exploring the Relation Between Plant Phosphorus Nutrition and Growth Promotion by Bacillus subtilis/amyloliquefaciens Strains
(2010-08-02)
The use of plant growth-promoting rhizobacteria (PGPR) as biofertilizers is of increasing interest due to economic and environmental issues. Phosphorus (P) is one of the most limiting plant nutrients because of its reduced ...
Nematode Community Structure and Effects on Peanut Production Systems
(2010-08-03)
Understanding the total nematode community in agronomic systems and its impact on crop health may provide insight into more sustainable management strategies. In this study the focus was on management of the peanut root-knot ...
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 ...
