To conduct laboratory experiments aimed at quantifying secondary acquisition of fungal conidia by western Xower thrips (Frankliniella occidentalis), an eYcient assay technique using Beauveria bassiana as the model fungus was developed. Various application protocols were tested and it was determined that the percent mortality did not vary among protocols. Peak mortality of secondinstar nymphs, u...

Aims: The main objective of the present study was to investigate the larvicidal effect of some biological control agents like Beauveria bassiana and Bacillus thuringiensis var. israelensis (B.t.i.) and some natural control agents as Diflubenzuron, Azadirachtin and Emamectin benzoate on Culex pipiens mosquito. The toxicity of binary mixtures of these control agents was also assessed. Methodology...

c s t u a 1 b d f a a i 1 b Collaborative research was conducted at the USDARS Subtropical Agricultural Research Center in southrn Texas to assess the microbial control potential of eauveria bassiana and Paecilomyces fumosoroseus gainst Bemisia whiteflies. Laboratory assays demontrated the capacity of both pathogens to infect Bemisia rgentifolii nymphs on excised hibiscus leaves incubated t rel...

in order to complete the microbial control of the sawthoothed beetle by the fungus beauvaria bassiana (isolate 441c) in ipm program of stored date, 9 edible and commercial vegetable oils including canola, soybean, sesame, corn, coconut, grape seed, olive, sunflower and almond were investigated to formulate the fungus. results showed that b. bassiana formulated with sesame oil was the most suita...

Commercial biopesticides based on the fungal pathogen Beauveria bassiana strain GHA and the bacterial pathogen Bacillus thuringiensis tenebrionis were applied alone and in combination (tank mixed) against larval populations of the Colorado potato beetle, Leptinotarsa decemlineata, in small plots of potatoes over three field seasons. Interactions between the two products were evaluated in terms ...

A culture independent method based on qPCR was developed for the detection and quantification of two fungal inoculants in soil. The aim was to adapt a genotyping approach based on SSR (Simple Sequence Repeat) marker to a discriminating tracing of two different species of bioinoculants in soil, after their in-field release. Two entomopathogenic fungi, Beauveria bassiana and B. brongniartii, were...
