Plant growth-promoting rhizobacteria (PGPR) mediate interactions between abiotic and biotic stresses in cool- and warm-season grasses
(2017-12-06)
Non-pathogenic, soil microbes that occupy the rhizosphere can influence plant growth and induce changes in the plant’s physiological, chemical, metabolic, molecular activities; influencing plant-microbe interactions with ...
Plasticity of Olfactory Response to Host-Related Plant Volatiles in The Parasitoid Microplitis croceipes
(2016-05-03)
Plants release blends of volatile organic compounds (VOCs) in response to herbivore damage. Parasitoids use certain VOCs as indirect cues to locate their herbivore hosts. However, response of parasitoids to these chemical ...

(2020-12-01)
Glutathione, a tripeptide (GSH; a 307 Da γ-L-glutamyl-L-cysteinyl-glycine peptide) is the most abundantly present, thiol in plants and animals, and considered as a master antioxidant. It prevents damage to cells caused by ...
Potential Effects of Biotic and Abiotic Stressors on the Reproductive Health of Honey Bees
(2020-11-30)
Apis mellifera Linnaeus honey bees are the most economically important pollinator species in the United States, yet colonies consistently experience high losses as a result of interacting biotic and abiotic stressors. My ...
The potential effects of red imported fire ants (Solenopsis invicta) on arthropod abundance and Cucumber mosaic virus
(2005-12-15)
Mutualisms involving ants and honeydew-producing insects such as aphids, scales, and whiteflies may dramatically affect the population dynamics of these herbivorous insects. Furthermore, changes in the population size of ...
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 ...
Probing the Adaptation Strategies in the Genus Xanthomonas
(2021-07-21)
Bacterial species belonging to the genus Xanthomonas can infect and cause severe diseases in a wide range of host plants including many economically important crops throughout the world. While the majority of studies ...
Production and characterization of Bt Cry1Ac resistance in bollworm, Helicoverpa zea (Boddie)
(2008-08-15)
Laboratory-selected Bt-resistant colonies are important tools for elucidating Bt resistance mechanisms and helping to determine appropriate resistance management strategies for Bt crops. Here, two laboratory populations ...
Reception of Human Odorants and Their Chemical Antagonists in the Yellow Fever Mosquito, Aedes aegypti
(2019-07-18)
The yellow fever mosquito Aedes aegypti (Linnaeus) (Diptera: Culicidae) is a vector of several tropical diseases, including yellow fever, dengue fever, Zika fever, and chikungunya. Mosquitoes use multiple cues such as CO2, ...
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 ...
Recruitment to and Defense of Aphids by Fire Ants and Native Ants and an Estimate of Their Trophic Positions Using Stable Isotopes
(2008-05-15)
The red imported fire ant, Solenopsis invicta, is an invasive ant known to form facultative mutualisms with aphids. Fire ants significantly reduce the abundance of aphid predators and herbivores on plants infested with ...
Red Imported Fire Ant Influences on White Grub Populations and Soil Foraging Characteristics in Managed Turfgrass
(2011-04-29)
White grubs (Coleoptera: Scarabaeidae) are a significant pest of managed turfgrass throughout the United States and are difficult to monitor because of their subterranean habitat. Recent reports have stated that white ...
Resistance Status of Aedes albopictus and Aedes aegypti from Alabama and Florida and Analysis Cytochrome P450 Genes Expression Level Compared with Susceptible and Resistant Strains
(2020-04-08)
Aedes albopictus and Aedes aegypti can transmit severe human diseases including dengue fever and yellow fever. When they are serious, these diseases can lead to human death and economic burden. Ae. albopictus has already ...
