Justin Renkema, PhD

Applied entomologist conducting research on biological, chemical and cultural practices for improving management of pests in fruit crops
Current research and/or projects
I conduct research on the ecology and biology of economically important insects and mites in fruit crops, with the goal of improving pest management through a better understanding of how to integrate biological, cultural, physical, and chemical control methods.
Research and/or project statements
Current projects:
- Steam treatment of transplants and biopesticide efficacy for controlling cyclamen mite in strawberry
- Interactions of entomopathogens and composts/mulches for white grub control in berry crops
- Developing molecular tools for improved spotted wing drosophila monitoring in fruit crops
- Identifcation of leafhoppers and their parasitoids in grapes
- Improving chilli thrips management in Florida strawberry
- Determing efficacy of novel natural enemies for spotted wing drosophila
