Thrilled to announce our latest publication in Biocontrol Science and Technology! 🌍🔬


This research showcases the power of international collaboration, led by Mavis Agyeiwaa Acheampong (University of Ghana), in collaboration with DRAUZIO EDUARDO NARETTO RANGEL of the Universidade Tecnológica Federal do Paraná, Brazil, and many others.


Amanor, G. T., Acheampong, M. A., Luke, B., Smith, D., Ryan, M., Kermode, A., Morris, J., Cornelius, E. W., Eziah, V. Y.,  Fening, K. O., Clottey, V. A., Rangel, D. E. N., Tyson C., & Mikaelyan, A. (2024) Viability and virulence of freeze-dried Beauveria bassiana, Metarhizium acridum, and Hirsutella thompsonii isolates under non-refrigerated conditions in Ghana, Biocontrol Science and Technology, DOI: 10.1080/09583157.2024.2332337


The study explores the viability and effectiveness of freeze-dried fungi used as biopesticides under non-refrigerated conditions, an aspect critical for their application in tropical regions where cold storage options like refrigeration might be limited🌞. Please join me in congratulating Mavis, undergraduate researcher Clara Tyson, who have been working on several entomopathogen-related projects in our lab!👏.


The work done in our lab was supported by the USDA Foreign Agricultural Service (FAS) Scientific Exchange Program (SEP) 🌱. Shoutout to José Cisneros and Adrienne LaBranche Tucker, Ph.D. at CALS International Programs for their exceptional leadership and constant support that makes cross-continental collaborations like this one possible.


Let’s keep pioneering sustainable solutions for our planet 🌎
