The Effects of Farmscaping Plants on the Abundance, Diversity, and Longevity of Arthropods in Organic Tomato Fields in Alabama
(2010-04-09)
Organic farming is the practice of cultivating crops without the use of synthetic pesticides or fertilizers. Farmscaping is habitat manipulation system of planting plants near the crop to attract beneficial insects by ...
The Sodium Channel Gene Expression on the Kdr Locus in the House Fly, Musca domestica and the Mosquito, Culex quinquefasciatus
(2010-07-14)
A point mutation of leucine to phenylalanine (L-to-F), resulting from a single nucleotide substitution in the sodium-channel of insects, is associated with pyrethroid resistance. In this study, to understand genetic basis ...
Mechanisms of Olfaction in Parasitic Wasps: Analytical and Behavioral Studies of Response of a Specialist (Microplitis croceipes) and a Generalist (Cotesia marginiventris) Parasitoid to Host-Related Odor
(2011-07-27)
Parasitic wasps (parasitoids) are known to utilize as host location cues various types of host-related volatile signals. These volatile signals could be plant-based, originate from the herbivore host, or be produced from ...
Response of Resistant Pepper Varieties to Viruses in the Genus Potyvirus
(2011-05-18)
Potyviruses are a persistent threat to bell pepper (Capsicum annuum L.) production worldwide. We have expended much effort to study the resistance response of pepper cultivars at cellular and whole plant levels. To evaluate ...
The use of Anaerobic Fermentation Acids and Aldehydes to Control Nematodes and Improve Soil Health
(2012-04-19)
There is increasing effort to develop cropping systems utilizing soil amendments, flooding, and tarping to control nematodes. The decrease in nematode populations under such anaerobic conditions is attributed to the ...
Assessing Soil Microbial Populations and Activity Following the Use of Microbial Inoculants: Effects on Disease Suppressiveness and Soil Health
(2008-09-09)
In recent years, assessing use of microbial inoculants for promotion of plant growth has increased. Optimizing application frequency of PGPR is critical to achieving the maximum benefit from this technology. The study ...
Studies on Cercospora Leaf Spot
(2008-09-09)
Fresh Pseudocercospora cornicola specimens were compared to an isotype specimen to confirm species identity. The two specimens proved to be the same taxonomic entity. The fungus was then redescribed and illustrated from ...
The role of calcium in the regulation of Xylella fastidiosa virulence
(2013-12-03)
The Gram-negative plant pathogenic bacterium Xylella fastidiosa inhabits the xylem vessels of the host, where it forms biofilms thought to be responsible for disease symptoms. Even though knowledge regarding the mechanism ...
Genomics of permthrin resistance in the Southern house mosquito, Culex quinquefasciatus Say
(2014-01-14)
The Southern house mosquito, Culex quinquefasciatus, is a vector of several human diseases including West Nile fever and St. Louis encephalitis, owing to its blood feeding behavior whereby the female takes multiple blood ...
Potential of plant growth-promoting rhizobacteria (PGPR) as a biological control agent against warm-season turfgrass pests
(2014-05-02)
Plant growth-promoting rhizobacteria (PGPR) are non-pathogenic, beneficial bacteria that colonize seeds and roots of plants to enhance plant growth. Despite work in agronomic crops, there has been little emphasis on ...
