Use and impact of endophytic entomopathogenic fungi: Their potential in the context of agricultural sustainability
Abstract The use of entomopathogenic fungi (EF) as endophytes is an environmentally friendly alternative for sustainable food production, given that the current paradigm in crop protection is based on the use of organosynthetic pesticides, with more than two million tons per year worldwide; EF has the ability to live within plant tissues as endophytes, acting as biopesticides. Under this scenario, this review analyzes and discusses the global status of the endophytic entomopathogenic fungi (EEF), their potential in plant protection against plant diseases and insect pests and as plant growth promoters. Successes and failures, and prospects for field application are examined. More than 7000 studies on EEF have been published, with important success cases. However, it is necessary to understand that the agricultural production is based on the use of external inputs, mainly pesticides. While progressive changes occur, it is fundamental to investigate the effect of these substances on the efficacy and persistence of EEF, without neglecting that the lack of knowledge of the effect of biotic and abiotic factors on EEF is an important cause of failures. Future studies should be focused on clarifying aspects such as: application strategies, endophytic persistence and transmission routes to improve the sustainability of agricultural production.
