carbon metabolism of beauveria bassiana may be related to virulence against plutella xylostella and leptinotarsa decemlineata
fermentation of 49 carbohydrates and oxidation and assimilation of 96 substrates were examined for ten beauveria bassiana isolates. principal component analysis indicated that there are significant differences among isolates for utilization of some substrates. esculine and d- glucose were positively fermented by all isolates. isolates were grouped into four clusters on the basis of hierarchial ...
متن کاملBIOLOGICAL CONTROLÐMICROBIALS Beauveria bassiana Horizontal Infection Between Cadavers and Adults of the Colorado Potato Beetle, Leptinotarsa decemlineata (Say)
The behavior of adult Colorado potato beetles (Leptinotarsa decemlineata) in the presence of Beauveria bassiana sporulating on cadavers was studied to determine the likelihood of disease infection as beetles emerge from the soil and colonize host plants. In 2001, the movement of single adultColoradopotatobeetleswasmonitored in arenas containing infective cadavers in differing spatial patterns b...

A tritrophic association is reported, involving a Colorado potato beetle (Leptinotarsa decemlineata) infected with Beauveria bassiana, which in turn was infected with Syspastospora parasitica.
متن کاملVariation in the Susceptibility of Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) When Reared on Different Host Plants to the Fungal Pathogen, Beauveria bassiana in the Field and Laboratory!
Environ. En!om,,!. 12: 1892-1897 (1983) ABSTRACT We determined the susceptibility of the Colorado potato beetle, Leptinotarsa decem/ineata (Say) to the fungal pathogen Beauveria bassiana (Balsamo)when reared on So/anum tuberosum L., So/anum dulcamara L., So/anum carolineme L., and Lycopersicwn escu/entum Miller growing in both the field and greenhouse. With the exceptionof L. escu/entwn, the ho...
متن کاملComparative virulence of Beauveria bassiana isolates against lepidopteran pests of vegetable crops.
Forty-three isolates of the entomopathogenic fungus Beauveria bassiana were screened for virulence against second-instar larvae of diamondback moth (Plutella xylostella) (DBM), European corn borer (Ostrinia nubilalis) (ECB), corn earworm (Helicoverpa zea) (CEW), and fall armyworm (Spodoptera frugiperda) (FAW); 30 of these isolates were tested against beet armyworm (Spodoptera exigua) (BAW). Hig...
متن کاملIsolation and Evaluation of Beauveria bassiana for Control of Coptotermes formosanus and Reticulitermes flavipes (Isoptera: Rhinotermitidae)
Six Beauveria bassiana (Balsamo) Vuillemin isolates were obtained from Reticulitermes flavipes (Kollar) and Coptotermes formosanus Shiraki in the U.S. and China. These isolates, plus the B. bassiana isolate 26037 from American Type Culture Collection that was isolated from Colorado potato beetle (Leptinotarsa decemlineata (Say)) were compared against C. formosanus and R. flavipes in the laborat...
