Innovative Microbial Control Methods for Insect Pest Management with Dr. David Shapiro
In this talk, Dr. David Shapiro, a leading supervisory research entomologist at the USDA-ARS Southeastern Fruit and Tree Nut Research Station in Byron, Georgia, discusses advanced research and applications in microbial control of insect pests. Dr. Shapiro’s presentation focuses on entomopathogenic nematodes and fungi as biopesticides. He explains their biology, commercial targets, and practical applications. He also covers their benefits and challenges, such as cost and environmental sensitivity, and introduces advanced concepts like microbial agents’ genetic enhancement and innovative application methods. Learn how these microbial control agents could revolutionize pest management in agricultural settings.

Dr. David Shapiro, a supervisory research entomologist, presented on microbial control using entomopathogenic nematodes (EPNs) and fungi to combat insect pests. These microbial agents, particularly nematodes and fungi like Bavaria bassiana, offer environmentally friendly pest control options, although challenges like cost and environmental sensitivity exist. Nematodes work symbiotically with bacteria to kill insects, making them effective against pests such as citrus weevils and mole crickets.
Dr. Shapiro’s research focuses on improving the efficacy of these microbial agents through strain improvement, hybridization, and novel application methods, such as using protective gels and the cadaver approach. He also highlighted the potential of endophytic fungi, which can live inside plants and protect against pests and diseases. Future research will aim to enhance production methods, develop cost-effective formulations, and explore the long-term benefits of endophytic fungi.
