Overview

Donald W. Roberts was affiliated with the Boyce Thompson Institute in the United States. Their research focused primarily on agricultural and biological sciences, with particular contributions to the fields of biochemistry, genetics, and molecular biology. Their work addressed topics spanning insect science, genetics, plant science, molecular biology, and ecology.

The scientist's research themes concentrated largely on entomopathogenic microorganisms in pest control, insect and arachnid ecology and behavior, insect resistance and genetics, and nematode management and characterization studies. Additional topics included forest insect ecology and management, insect and pesticide research, and algal biology and biofuel production.

Donald W. Roberts contributed to various scientific publications including:

  • UV-B tolerances of conidia, blastospores, and microsclerotia of Metarhizium spp. entomopathogenic fungi (2020, Journal of Basic Microbiology)
