Highly active antagonistic actinomycete Streptomyces griseoviridis and entomopathogenic fungus Beauveria bassiana were applied to the soil separately and together (in association) in the laboratory experiments. We assessed survival rate, insecticidal and fungistatic activity of these strains. We also tested the influence of synthetic insecticide Regent 25® (fipronil 25g/l) on investigated param...

In this study, the entomopathogenic fungi; Beauveria bassiana, Isaria fumosorosea and Metarhizium anisopliae were evaluated against fourth nymphs adults of green shield bug, P. prasina. The experiment was conducted both under field laboratory conditions. Isolates included six one fumosorosea. bioassayed in Four replications bioassays analyzed daily for 14 days. LT50 LT95 values experimented iso...

Beauveria bassiana is a fungal entomopathogen with the ability to colonize plants endophytically. As an endophyte, B. bassiana may play a role in protecting plants from herbivory and disease. This protocol demonstrates two inoculation methods to establish B. bassiana endophytically in the common bean (Phaseolus vulgaris), in preparation for subsequent evaluations of endophytic biological contro...

Ten strains of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana were evaluated to find the most effective strain for optimization studies. The first criterion tested for strain selection was the mortality (> 50%) of Spodoptera litura larvae after inoculation of the fungus for 4 days. Results on several bioassays revealed that B. bassiana BNBCRC showed the most virulence ...

Low impact alternatives to synthetic insecticides for the control of apple sawfly (Hoplocampa testudinea Klug) are scarce encumbering pest management in organic apple orchards. We investigated the soil persistence and field efficacy of the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin (BotaniGard) against apple sawfly under common organic orchard practices. We also assessed the...

The silkworm Bombyx mori is an economically important species. White muscardine caused by Beauveria bassiana is the main fungal disease in sericulture, and understanding the silkworm responses to B. bassiana infection is of particular interest. Herein, we investigated the molecular mechanisms underlying these responses in two silkworm strains Haoyue (HY, sensitive to B. bassiana) and Kang 8 (K8...

1991). Only recently have investigations focused on relationships between B. bassiana and the corn plant. Field and greenhouse studies were conducted to determine the proBeauveria bassiana forms an endopytic relationship with clivity of Bacillus thuringiensis (Bt) (Berliner)-transgenic corn (Zea mays L.) to form an endophytic relationship with Beauveria bassiana, the corn plant and provides sea...

Essential oils have antifungal and antipathogenic effects and therefore are targets in plant pathology research for their potential uses as natural substitutes for inorganic plant pesticides. Beauveria bassiana, an entomopathogenic fungus, can endophytically colonize a vast number of plant species and trigger induced systemic resistance against plant pathogens. Spore germination is the most vul...

The beetle Alphitobius diaperinus (Panzer), considered a worldwide pest in the poultry industry, is difficult to control and it is a vector for pathogens. The objective of this study was to evaluate the biological control of the lesser mealworm, by strains of fungi Beauveria bassiana, Cladosporium sp. and Trichoderma sp. Larvae and adults of the A. diaperinus were inoculated with suspensions of...
