PhD, Entomology, Rhodes University (2016)

Candice completed her PhD at Rhodes University in 2016 where she investigated the use of entomopathogenic fungi as control agents of the citrus pest, false codling moth. She continues to conduct research within the field of agricultural entomology with focus on microbial control and the use of non-chemical control approaches for pest management. 

Research Interests

  • Biological control of insect pests
  • Agricultural Entomology
  • Fungal pathogens
  • Integrated pest management
