Trichoderma as biocontrol agent against pests: New uses for a mycoparasite

Biological Control, Journal Year: 2021, Volume and Issue: 159, P. 104634 - 104634

Published: April 22, 2021

Insects are the main pest in agricultural systems, causing significant losses crop productivity and storage. During last decades control of insects has been carried out through uncontrolled massive use chemical insecticides, very harmful to environment health, which requires development new efficient safe alternatives. Numerous fungal species have described as entomopathogens insect pests, well plant endophytic fungi. In this sense, Trichoderma is a genus filamentous fungi widely studied used biocontrol agent agriculture on pathogenic due its ability parasitize them (mycoparasitism), among other mechanisms action. recent years, possibility using for considered, both directly indirectly. The studies date reported that capable controlling parasitism production insecticidal secondary metabolites, antifeedant compounds repellent metabolites. And indirectly activation systemic defensive responses, attraction natural enemies or insect-symbiotic microorganisms. Therefore, not only effective against pathogens, but also representing future alternative sustainable agriculture.

Endophytes and their potential in biotic stress management and crop production

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: Oct. 17, 2022

Biotic stress is caused by harmful microbes that prevent plants from growing normally and also having numerous negative effects on agriculture crops globally. Many biotic factors such as bacteria, fungi, virus, weeds, insects, nematodes are the major constrains of tends to increase reactive oxygen species affect physiological molecular functioning led decrease in crop productivity. Bacterial fungal endophytes solution overcome tasks faced with conventional farming, these environment friendly microbial commodities colonize plant tissues without causing any damage. Endophytes play an important role host fitness, uptake nutrients, synthesis phytohormone diminish injury triggered pathogens via antibiosis, production lytic enzymes, secondary metabolites, hormone activation. They reported help coping stress, improving soil health, respectively. Therefore, usage biofertilizers biocontrol agent have developed eco-friendly substitute destructive chemicals for development mitigation stress. Thus, this review highlighted potential biofertilizers, agent, maintenance health sustainable agriculture.

Entomopathogenic fungi and their relevance in sustainable agriculture: A review

Cogent Food & Agriculture, Journal Year: 2023, Volume and Issue: 9(1)

Published: March 2, 2023

The use of entomopathogenic fungi (EPF) like Beauveria, Metarhizium, Lecanicillium, and Isaria is upsurging in recent years for the management crop insect pests. EPF are considered better than synthetic insecticides as they safe humans, sustainable to environment, target-specific nature. Many these pathogenic economically important pests thus capable controlling them. They cheaper long run, show lesser residual effects, able overcome problem resistance. degrades host cuticle proliferates hemolymph hyphal bodies, secreting toxins responsible death insects. later saprophytic growth leads production fungal spores reinfecting other hosts. Different commercial formulations available globally such liquid formulation, wettable powder, suspensible granules, so on. These under different trade names can be used several crops at recommended dosage obtain optimum results. storage conditions should maintained retain viability EPF. Modern biotechnological interventions could vital enhancing efficacy entomopathogens by manipulating their traits. Specialized researches necessary understand interaction between EPF, insects, crops, environment order explore best formulation mycoinsecticides. This review explores overview its mode action, significance, formulations, future prospects, summary findings. Readers realize essence agriculture through this review.

A life-and-death struggle: interaction of insects with entomopathogenic fungi across various infection stages

Frontiers in Immunology, Journal Year: 2024, Volume and Issue: 14

Published: Jan. 8, 2024

Insects constitute approximately 75% of the world’s recognized fauna, with majority species considered as pests. Entomopathogenic fungi (EPF) are parasitic microorganisms capable efficiently infecting insects, rendering them potent biopesticides. In response to infections, insects have evolved diverse defense mechanisms, prompting EPF develop a variety strategies overcome or circumvent host defenses. While interaction mechanisms between and is well established, recent findings underscore that their interplay more intricate than previously thought, especially evident across different stages infection. This review primarily focuses on insect strategies, centered around three infection stages: (1) Early stage: involving pre-contact detection avoidance behavior in along induction behavioral responses upon contact cuticle; (2) Penetration intra-hemolymph growth initiation cellular humoral immune functions while symbiotic microbes can further contribute resistance; (3) Host insect’s death ultimate confrontation pathogens insects. Infected strive separate themselves from healthy population, rely infected spread new hosts. Also, we discuss novel pest management strategy underlying cooperation disturbing system. By enhancing our understanding insect, this provides perspectives for EPF-mediated developing effective fungal insecticides.
