The Discovery Of Metarhizium Anisopliae (Metchnikoff) Sorokin Isolates From Arkansas And Their Pathogenicity To Amblyomma Americanum L., Austin Goldsmith
Graduate Theses and Dissertations
The lone star tick Amblyomma americanum L. is the most abundant tick in Arkansas and has been implicated as a vector of many important disease-causing pathogens. Many species of entomopathogenic fungi have been isolated from several species of ticks, with some of these fungi being utilized for tick biocontrol. However, few studies have assessed the pathogenicity of entomopathogenic fungi to A. americanum. The objectives of this study were to: isolate and identify native Arkansas isolates of entomopathogenic fungi from wild A. americanum ticks exposed to soil and to compare the pathogenicity of one isolate (Metarhizium anisopliae (Metchnikoff) Sorokin isolate Savoy …

This study describes in vitro and in vivo azygospore production by nine isolates of Entomophaga maimaiga, a fungal pathogen of the gypsy moth, Lymantria dispar. The three E. maimaiga isolates that consistently produced azygospores in vitro were also strong producers of azygospores in vivo. However, two additional isolates that were strong azygospore producers in vivo did not produce azygospores in vitro. Isolates that produced azygospores in vitro produced both conidia and azygospores more frequently in vivo than isolates not producing azygospores in vitro. In vitro azygospore production varied over time as well as by isolate. After >2 years of cold …
