Abstract: Entomopathogenic fungi can provide a set of ecological services, such
as suppressing arthropod pests and plant pathogens. In this study, novel
indigenous Beauveria caledonica (Bc) strains were isolated from naturally
infected banana weevils (Cosmopolites sordidus) occurring in commercial banana
plantations in Brazil. The prevalence of infection by Bc strains on
field-caught C. sordidus ranged from 1.3% to 12.9%. Similar to the Beauveria
bassiana strains tested, none of the Bc strains caused more than 50% weevil
mortality at a concentration of 1 x 10(8) conidia ml(-1) . Bc strain CMAA1810
caused the highest mortality in C. sordidus and had enhanced insecticidal
activity when formulated with an emulsifiable oil. In paired co-culture assays,
this same strain showed a significant growth-inhibitory effect on the causal
agent of Fusarium banana wilt (Fusarium oxysporum f. sp. cubense, Foc) of twofold
magnitude compared with the control. Cell-free crude filtrates derived from the
red-pigmented culture broth of Bc (CMAA1810) strongly reduced Foc conidial
viability, and this inhibitory activity was inversely related to the age of the
Bc culture. Crude concentrated filtrates from 4-day-old cultures exhibited the
strongest antifungal activity (13-fold) compared with untreated Foc conidia. The
abundant compound identified in the crude filtrate of Bc was oosporein
(1,4-dibenzoquinone) present at a concentration of 0.829 ± 0.018 mg g(-1) dry
matter, and the antifungal activity of the filtrate was demonstrated.
These results indicated that Bc strains might have the potential to manage both
C. sordidus and Foc, two of the major phytosanitary problems in banana crops
worldwide. Further research under field conditions using suitable formulations of
virulent Bc strains in combination with the metabolite oosporein is needed to
evaluate their efficacy in the management of C. sordidus and Foc in banana
plantations. MenosAbstract: Entomopathogenic fungi can provide a set of ecological services, such
