Species Diversity of Hickory-feeding Phylloxerans (Hemiptera: Phylloxeridae) in the U.S.
(2019-07-23)
During the spring months, hickories throughout the Eastern U.S. become adorned with abnormal growths or galls on the leaf or stem tissue. Many of these galls are caused by phylloxerans (Hemiptera: Phylloxeridae: Phylloxera ...
Evaluation of the genetic diversity, temporal distribution, and management of Fusarium oxysporum f. sp. vasinfectum in the National Cotton Fusarium Wilt Evaluation Field
(2020-11-23)
Fusarium oxysporum f. sp. vasinfectum (FOV), the causal agent of cotton Fusarium wilt, has been causing losses in the cotton industry around the world for more than 125 years. Large genetic diversity exists within this ...
Physiology and Chemical Ecology of Solenopsis Fire Ants: Interactions with Biotic and Abiotic Factors in Their Environment
(2020-05-14)
Interactions between organisms and the environment affect the survival and distribution of species. Biotic and abiotic factors impact the adaptations of Solenopsis fire ants (Hymenoptera: Formicidae) in the southeastern ...
Entomopathogenic Nematode Management of Small Hive Beetles (Aethina tumida) in Three Native Alabama Soils Under Low Moisture Conditions
(2020-07-17)
The overall goal of this work was to determine the efficacy of entomopathogenic nematodes (EPNs) on Aethina tumida Murray (Coleoptera:Nitidulidae) small hive beetle (SHB) in different soil types under low moisture conditions ...
Applied and Basic Aspects of Copper Interaction with Xylella fastidiosa
(2020-11-23)
Xylella fastidiosa, a gram-negative, xylem-limited plant pathogenic bacterium that causes severe diseases and asymptomatic colonization in more than 600 different plants worldwide, including many economically important ...
Recruiting lady beetles using olfactory and visual cues for the biocontrol of Acanthococcus lagerstroemiae (Hemiptera: Eriococcidae)
(2020-11-30)
Acanthacoccus lagerstroemiae (crapemyrtle bark scale, CMBS) is an exotic scale insect that feeds on the sap of crapemyrtle trees as its primary host. Heavy Infestations of CMBS leads to reduced flowering and sooty mold ...
Genetic diversity of the fungal pathogen Corynespora cassiicola and its fungicide resistance
(2020-11-23)
Corynespora cassiicola C.T. Wei is a widespread phytopathogenic fungus that causes disease in tropical and subtropical regions in up to 400 plant species, including fruits, vegetables, ornamentals, forestry, and row crops. ...
Enhancing plant growth, drought stress tolerance, and biological control capacities of PGPR strains with exogenous pectin-rich amendments
(2020-06-15)
Bacillus velezensis is a plant growth-promoting rhizobacterium (PGPR) that promotes plant growth, enhances drought stress tolerance, and suppresses plant pathogens. However, little is known about the effects of exogenous ...
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, ...
Suppression of Wolbachia mediated Cytoplasmic Incompatibility
(2020-07-17)
Insect biocontrol applications often hinge upon insect reproduction. Wolbachia are maternally inherited intracellular bacteria that infect insects. Wolbachia sterilizes a mosquito sperm resulting in a lethal embryonic ...
