Potential of plant growth-promoting rhizobacteria (PGPR) as a biological control agent against warm-season turfgrass pests 

Coy, Richard Murphey (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 ...

Recruiting lady beetles using olfactory and visual cues for the biocontrol of Acanthococcus lagerstroemiae (Hemiptera: Eriococcidae) 

Ibiyemi, Oluwatomi (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 ...

Red Imported Fire Ant Influences on White Grub Populations and Soil Foraging Characteristics in Managed Turfgrass 

Barden, Samuel (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 ...

Silvicultural Disturbances Affect on Root-feeding Bark Beetle Populations and the Incidence of Ophiostomatoid Fungal Species Contributing to Southern Pine Decline 

Zeng, Yuan (2012-04-12)
Root-feeding beetles and weevils are known to be vectors of ophiostomatoid fungi which contribute to Southern Pine Decline (SPD) in the southeastern United States. This study examined population changes of Hylastes spp. ...

Species Diversity of Hickory-feeding Phylloxerans (Hemiptera: Phylloxeridae) in the U.S. 

Hamilton, Fredericka (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 ...

Sprayable formulations of dsRNA as a tool for management of Popillia japonica (Coleoptera: Scarabaeidae) 

Carroll, Elijah (2023-11-27)  ETD File Embargoed
RNA interference (RNAi) mediated by environmental dsRNA presents a promising, target-specific approach to providing plant-protection against damage from invasive and outbreak insect pests. However, this approach has not ...

Use of Plant Growth-Promoting Rhizobacteria in Tall Fescue and Bermudagrass Forage Systems 

Cole, Madison (2021-07-12)
A 2-yr study was conducted evaluating plant growth-promoting rhizobacteria (PGPR) as an alternative N source for ‘Russell’ bermudagrass (Cynodon dactylon) and ‘KY 31’ tall fescue (Lolium arundinaceum) at two locations in ...

Visual, Acoustic, and Volatile Cues to Improve Performance of Trapping Ambrosia Beetles (Coleoptera: Curculionidae) 

Gorzlancyk, Austin (2013-11-11)
Three widely distributed species of ambrosia beetles (Coleoptera: Curculionidae: Scolytinae), Xylosandrus germanus Blandford, Xylosandrus crassiusculus Motschulsky, and Cnestus mutilatus Blandford are introduced pests that ...
