Abstract Entomopathogenic fungi are the most effective control remedy against a wide range of medical and agricultural important pests. The present study aimed to isolate, identify, assess virulence Metarhizium rileyi Spodoptera litura frugiperda pupae under soil conditions. biotechnological methods were used identify isolate as M. . fungal conidial pathogenicity (2.0 × 10 7 , 2.0 8 9 11 conidia/mL −1 ) was tested prepupae S. at 3, 6, 9, 12 days after treatments. Additionally, artificial soil‐conidial assay performed on nontarget species earthworm Eudrilus eugeniae using conidia. results showed that caused significant mortality rates in (61‐90%), more susceptible than (46%–73%) day posttreatment.

Abstract Chemical pesticides are synthetic substances created to manage plant pests. Frequent chemical usage causes extensive damage crops and contributes pest resistance, leading environmental contamination, harm non‐target organisms, the emergence of pesticide‐resistant species, potential health hazards for humans. The aim this study is isolate, identify, characterize biocontrol agents Trichoderma harzianum evaluate their effects on various phytopathogens. T. were tested against fungal phytopathogens, including Sclerotium rolfsii , Alternaria sp ., Pythium aphanidermatum Macrophomina phaseolina Fusarium oxysporum Helminthosporium sativum Aspergillus niger . results clearly showed that, compared other TVK1 demonstrated highest ability suppress with a growth inhibition rate 2.48 cm per day.

Beauveria bassiana AAD16, isolated from Allomyrina dichotoma , shows promise as a mycoinsecticide against various coleopterans. However, assessing non-target impacts on beneficial beetles like ladybirds is crucial before commercialization. Here we assessed the compatibility between ladybird and B . AAD16. The virulence of AAD16 strain was compared with that an available commercial strain, GHA, for two developmental stages (adults 3 rd instar larvae) coccinellids, Harmonia axyridis Pallas Chilocorus spp. Say using topical (1μl) application method. ST 50 life were not different tested fungal strains. Mycosis rates recorded dead bodies also significant except in which showed 36 63% GHA strains H while those 40 63%, respectively. In adult stage, mycosis (males females separately) (20–23) % (26–30) strains, (unsexed) 23 30%, caused similar mortality both species. Therefore, conclude would increase risk to these insects pathogen commercialized.

ABSTRACT Pests and diseases have a significant impact on crop health yields, posing serious threat to global agriculture. Effective management strategies, such as integrated pest (IPM), including rotation, use of synthetic pesticides, biological control, resistant/tolerant varieties, are essential mitigate these risks ensure sustainable agricultural practices. Fungal bioagents play an important role in managing phytopathogens insect pests by acting agents. They promote healthy plant growth enhancing the uptake nutrients combating systemic resistance plants. Furthermore, fungal environmentally friendly, reducing application fungicides insecticides minimizing their negative crops environment. Their IPM promotes agriculture ensures high‐quality while maintaining soil microbial biodiversity. These rich sources volatile organic compounds (VOCs), which communication during interaction with phytopathogens. In management, VOC production beneficial fungi is accountable for efficacy against pathogens. Thus, this review discusses producing VOCs, extraction methods VOC, VOC‐producing disease knowledge gaps, future research areas.
