Overview

What is he best known for?

The fields of study he is best known for:

  • Fungus
  • Botany
  • Ecology

The scientist’s investigation covers issues in Metarhizium anisopliae, Botany, Conidium, Germination and Microbiology. In his study, Fungus is strongly linked to Entomopathogenic fungus, which falls under the umbrella field of Metarhizium anisopliae. Fungi imperfecti and Metarhizium are the subjects of his Botany studies.

He focuses mostly in the field of Conidium, narrowing it down to topics relating to Mycelium and, in certain cases, Mannitol and Trehalose. His Germination study contributes to a more complete understanding of Horticulture. The Microbiology study which covers Cuticle that intersects with Biochemistry and Extracellular.

His most cited work include:

  • Construction of an improved mycoinsecticide overexpressing a toxic protease (330 citations)
  • Metarhizium spp., cosmopolitan insect-pathogenic fungi: mycological aspects. (328 citations)
  • Variability in conidial thermotolerance of Metarhizium anisopliae isolates from different geographic origins (131 citations)

What are the main themes of his work throughout his whole career to date?

His scientific interests lie mostly in Botany, Metarhizium anisopliae, Conidium, Microbiology and Metarhizium. His Botany study often links to related topics such as Horticulture. His Metarhizium anisopliae research includes themes of Appressorium, Spore, Cuticle and Biochemistry.

His Conidium study integrates concerns from other disciplines, such as Entomopathogenic fungus, Mannitol, Germination and Mycelium. His biological study spans a wide range of topics, including Abiotic component and Tick. His work on Metarhizium acridum and Metarhizium flavoviride as part of general Metarhizium study is frequently connected to Mormon cricket, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.

He most often published in these fields:

  • Botany (45.00%)
  • Metarhizium anisopliae (41.00%)
  • Conidium (38.00%)

What were the highlights of his more recent work (between 2009-2021)?

  • Metarhizium (27.00%)
  • Conidium (38.00%)
  • Microbiology (29.00%)

In recent papers he was focusing on the following fields of study:

His main research concerns Metarhizium, Conidium, Microbiology, Metarhizium anisopliae and Botany. His research in the fields of Metarhizium acridum overlaps with other disciplines such as Potato dextrose agar. The Conidium study combines topics in areas such as Germination and Mycelium.

He has researched Microbiology in several fields, including Biochemistry and Tick. His study focuses on the intersection of Metarhizium anisopliae and fields such as Appressorium with connections in the field of Germ tube and Abiotic component. Botany is often connected to Horticulture in his work.

Between 2009 and 2021, his most popular works were:

  • Biological control of insects in Brazil and China: history, current programs and reasons for their successes using entomopathogenic fungi (110 citations)
  • Perspectives on the potential of entomopathogenic fungi in biological control of ticks (88 citations)
  • Stress tolerance and virulence of insect-pathogenic fungi are determined by environmental conditions during conidial formation (87 citations)
