Entomopathogenic

Definition

Of or pertaining to pathogens that cause disease in insects; describes organisms, infections, or mechanisms specifically lethal or debilitating to arthropod hosts, most commonly insects. The term distinguishes insect-specific pathogenicity from generalist or vertebrate-targeting pathogens, and is applied to fungi, bacteria, nematodes, and viruses used in biological control or studied in insect disease ecology.

Etymology

Greek entomon (insect) + pathogenic (disease-producing)

Example

Entomopathogenic fungi such as Beauveria bassiana infect through the cuticle, producing lethal mycoses in caterpillars and beetles, and are formulated as commercial biopesticides against crop pests.

Synonyms

• insect-pathogenic

Related Terms

• entomopathogen
• Biological control
• mycoinsecticide
• Beauveria
• Metarhizium
• host specificity
• Virulence

Usage Notes

Used primarily as an adjective modifying the pathogen type (entomopathogenic nematode, entomopathogenic virus) or the infection process. Not all insect pathogens are entomopathogenic in the strict sense—some are opportunistic or facultative. Contrast with 'phytopathogenic' (plant-pathogenic) or 'zoonotic' (vertebrate-infecting). The term implies adaptation to insect hosts, though host range varies widely among species.
