Uso de Metarhizium robertsii no controle biológico de estágios imaturos de nematoides gastrintestinais de caprinos

Brazilian Journal of Animal and Environmental Research
As verminoses gastrintestinais representam um dos principais entraves da caprinocultura, reduzindo o desempenho produtivo e comprometendo a sanidade dos rebanhos.

Increased heat tolerance afforded by oil-based conidial formulations of Metarhizium anisopliae and Metarhizium robertsii [PDF]

Biocontrol Science and Technology, 2017
ABSTRACTThe thermotolerance of oil-based conidial formulations of Metarhizium anisopliae s.l. (IP 46) and Metarhizium robertsii (ARSEF 2575) were investigated. Conidia of IP 46 or ARSEF 2575 were suspended in different adjuvants and exposed to 45 ± 0.2°C for 4, 6, 8 or 24 h; their viability was then assessed after 48 h incubation at 27 ± 1°C.

Entomopathogenic Metarhizium and Beauveria species are associated with distinct geographic, management, and environmental factors, as well as plant communities [PDF]

Applied and Environmental Microbiology
Entomopathogenic fungi of the genera Metarhizium and Beauveria are important natural regulators of arthropod populations. To investigate their distribution and ecological drivers in real-world permanent grasslands, we did a survey analyzing fungal ...

Roles of BrlA and AbaA in Mediating Asexual and Insect Pathogenic Lifecycles of Metarhizium robertsii [PDF]

J Fungi (Basel), 2022
BrlA and AbaA are key activators of the central developmental pathway (CDP) that controls asexual development in Aspergillus but their roles remain insufficiently understood in hypocerealean insect pathogens. Here, regulatory roles of BrlA and AbaA orthologs in Metarhizium robertsii (Clavicipitaceae) were characterized for comparison to those ...

Metarhizium Associated with Coffee Seedling Roots: Positive Effects on Plant Growth and Protection against Leucoptera coffeella

Agriculture, 2022
Metarhizium species can be mutualistic symbionts of plants. They are able to colonize roots, promote plant growth and provide protection against pests. We previously found Metarhizium robertsii and M.

Testing Virulence of Different Species of Insect Associated Fungi against Yellow Mealworm (Coleoptera: Tenebrionidae) and Their Potential Growth Stimulation to Maize

Plants, 2021
This paper investigates 71 isolates of two genera of entomopathogens, Metarhizium and Beauveria, and a biostimulative genus Trichoderma, for their ability to infect yellow mealworms (Tenebrio molitor) and to stimulate maize (Zea mays) growth.

Abscisic acid implicated in differential plant responses of Phaseolus vulgaris during endophytic colonization by Metarhizium and pathogenic colonization by Fusarium

Scientific Reports, 2021
Metarhizium robertsii is an insect pathogen as well as an endophyte, and can antagonize the phytopathogen, Fusarium solani during bean colonization. However, plant immune responses to endophytic colonization by Metarhizium are largely unknown. We applied

Multi-Trait Biochemical Features of Metarhizium Species and Their Activities That Stimulate the Growth of Tomato Plants

Frontiers in Sustainable Food Systems, 2020
The interaction between Metarhizium spp. and plant roots may induce host plant growth and help control below- and above-ground pests and diseases. We conducted in vivo and in vitro bioassays using native Brazilian isolates of Metarhizium robertsii (ESALQ

Functional Analysis of Keto-Acid Reductoisomerase ILVC in the Entomopathogenic Fungus Metarhizium robertsii. [PDF]

J Fungi (Basel), 2021
Ketol-acid reductoisomerase (ILVC) is the second enzyme in the branched-chain amino acid (BCAA) biosynthesis, which regulates many physiological activities in a variety of organisms from bacteria to fungi and plants. In this work, function mechanisms of ILVC in Metarhizium robertsii Metchnikoff (Hypocreales: Clavicipitaceae) were explored with site ...

Activation of microlipophagy during early infection of insect hosts by Metarhizium robertsii. [PDF]

Autophagy, 2022
The requirement of macroautophagic/autophagic machinery for filamentous fungal development and pathogenicity has been recognized, but the underlying effects and mechanisms remain elusive. The insect pathogenic fungus Metarhizium robertsii infects hosts by cuticular penetration through the formation of the infection structure appressoria.
