What is Entomopathogenic Fungi?
Entomopathogenic fungi are insect-pathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae used in biological pest control to infect and kill arthropod hosts.
These fungi penetrate insect cuticles via enzymes and toxins, proliferate inside the host, and produce conidia for dispersal. Key species include Beauveria bassiana (Xiao et al., 2012, 669 citations) and Metarhizium anisopliae (Gao et al., 2011, 647 citations). Over 10 papers in the list detail their genomics, safety, and field applications.
Why It Matters
Entomopathogenic fungi reduce reliance on chemical pesticides, targeting pests like olive fly (Yousef-Yousef et al., 2018, 499 citations) and mosquitoes (Scholte et al., 2004, 521 citations) with minimal environmental impact. Zimmermann (2007, 523 citations) confirms Metarhizium anisopliae safety for commercial use. Van Lenteren et al. (2017, 981 citations) report application on 30 million ha worldwide, supporting sustainable agriculture.
Key Research Challenges
Formulation Stability
Fungal conidia lose viability under UV exposure and desiccation during storage and field application. Gao et al. (2011) highlight environmental sensitivity in Metarhizium genomes. Yousef-Yousef et al. (2018) achieved 70% olive fly reduction via soil treatments but note persistence issues.
Host Virulence Mechanisms
Cuticle-degrading enzymes and toxins vary across insect hosts, limiting broad efficacy. Xiao et al. (2012) identify genomic adaptations in Beauveria bassiana for entomopathogenicity. Scholte et al. (2004) review mosquito-specific challenges in fungal infection cycles.
Field Efficacy Variability
Environmental factors like humidity and temperature reduce consistent pest control in crops. Zimmermann (2007) summarizes safety but flags variable performance data. Van Lenteren et al. (2017) note gaps in scaling augmentative releases.
