Prospect of Endophytic Fungal Entomopathogens for Pest Management
2021
Endophytic fungal entomopathogens could offer a number of benefits to their host plants, which include protection
against the primary pests, resistance against microbial pathogens, stimulation of growth, or increase of heavy metal or
drought tolerance. However, all reports, so far, indicate that colonization of some plants by entomopathogenic fungi
seemly confer only certain benefits to their hosts or else only one parameter was examined. Our study underscores
the practicability of introduction of specific insect fungal pathogen strains into host plants as endophytes that could
simultaneously promote host plant growth and offer plant protection against microbial pathogens, and/or insect
pests, which highlights the prospect of endophytic fungal entomopathogens for pest management. Here, we further
commented on the study-involved issues and the factors that possibly affect colonization by fungal entomopathogens
and the benefits to the host plant offered by the endophytes. Moreover, we put forward the possible link of some
plant morphological changes and/or stimulation of some plant defense pathways with the resistance of the host
plants against insect/ microbial pathogens, although the underlying mechanism remains somewhat of a mystery that
should be uncovered in the future.
