| Abstract/Contents: | "Greenhouse and field studies were conducted to determine the persistence of Beauveria bassiana (Balsamo) Vuillemin conidia when applied in an emulsified oil formulation to turfgrass. Conidial viability of three different strains of B. bassiana was determined by washing conidia from the turfgrass, exposing the conidial solution to a two-component nucleic acid stain, and examining the conidia with fluorescence microscopy. Daata from the field studies show significant strain differences in performance over time as measured by mean percentage conidial viability. Two B. bassiana strains, DB-2 and 110-22, exhibited significantly higher levels of viability compared to BotaniGard®, a commercially available strain. All three isolates showed some viability in two different field sites after a month of exposure to high temperatures and ultraviolet light. A topical bioassay exposed nymphal Scapteriscus species mole crickets to different rates of each of the three strains of this fungus. There was significant variation in the survival functions for mole crickets exposed to the fourteen different treatments (four rates of each of the three strains plus two control treatments). BotaniGard® exhibited the greatest effect on mole cricket mortality during the first two weeks after treatment with DB-2 having the second greatest effect, and 10-22 the least. Results from these studies indicate a need for further evaluation of the environmental conditions that affect conidial viability in turfgrass and emphasize the importance of appropriate strain selection to maximize efficacy. This was the first study of its kind to evaluate the viability of entomopathogenic conidia in turfgrass and there are implications for the use of fluorescence microscopy technique in many other systems." |
