Investigating Vector-Virus-Plant interactions influencing transmission efficiency of Tomato yellow leaf curl virus and Tomato mottle virus by Bemisia tabaci
(2018-07-20)
The whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) causes crop damage globally by feeding on phloem sap with their piercing-sucking mouthparts, excreting honeydew which promotes growth of sooty mold, and by transmitting ...
Investigation and Characterization of Antibacterial Proteins from the Eastern Subterranean Termites Reticulitermes flavipes in Response to Multidrug Resistant Bacteria
(2017-04-20)
Immune system of insects has been of great interest for discovering novel compounds against microbes. Subterranean termites (Blattodea: Isoptera: Rhinotermitidae), especially the Reticulitermes species, have a wide ...
Investigation of bioactivity and variations in alkaloid and hydrocarbon profiles of Solenopsis invicta Buren minim workers in relation to their age
(2017-07-31)
Red imported fire ant, Solenopsis invicta Buren, is a significant invasive pest introduced
into the United States in the early 1930s. Venom alkaloids and hydrocarbons play important
roles in the social life of the red ...
Investigation of biotic and abiotic factors contributing to yield loss caused by Cotton leafroll dwarf virus
(2023-07-26)
Cotton leafroll dwarf virus (CLRDV) is an aphid transmitted virus that has been reported in cotton producing states across the southeastern United States, initially causing significant yield losses. Yield losses in recent ...
An Investigation of the Coevolutionary Relationship Between Aprostocetus hagenowii (Ratzburg) (Hymenoptera: Eulophidae) and its Cockroach (Blattodea) Hosts
(2023-08-02)
Oothecal parasitoid wasps (Hymenoptera) parasitize the egg cases (oothecae) of cockroaches (Blattodea). Oothecal parasitoids must have developed numerous adaptations to locate, parasitize, and develop within their hosts, ...
Investigation of Ticks and Tick-Borne Pathogens in Deciduous Forests of Eastern Central Alabama
(2017-01-05)
Ticks are obligate hematophagous arthropods, and as vectors of human disease, they are second only to mosquitoes in medical importance. There are many unknowns in Alabama regarding ticks and tick-borne diseases that require ...
Isolation and Assessment of Nitrogen-Fixing and Phosphate-Solubilizing Bacteria for Use as Biofertilizers
(2014-12-10)
Nitrogen and phosphorus are essential macronutrients for plant growth. The major sources of N and P in agriculture are chemical fertilizers. Nitrogen in the soil can be lost due to denitrification, leaching, and volatilization. ...
Limits on populations of herbivorous insects
(2021-12-15)
Herbivorous insect populations are necessarily limited by biotic and abiotic factors. This dissertation seeks to uncover some of those limiting factors using using synthetic comparative statistical analyses including ...
Limonene for the management of Crape Myrtle Bark Scale (Acanthococcus lagerstroemiae)
(2024-04-23)
Crape myrtle bark scale (CMBS, Acanthococcus lagerstroemiae) is an invasive pest of crape myrtles first introduced to the United States less than 20 years ago. CMBS reduce the aesthetic value of these ornamental trees which ...
Management of Aphis gossypii Populations and the Spread of Cotton leafroll dwarf virus in Southeastern Cotton Production Systems
(2020-07-14)
Cotton aphid, Aphis gossypii Glover is a highly polyphagous pest known to cause both direct and indirect damage to cotton. Management of A. gossypii is a concern in Alabama due to two emerging problems, insecticide resistance, ...
