Article Abstract
This work presents the biocidal effects and chemical compositions of two essential oils (EOs) obtained by hydrodistillation of subsp and subsp. . The two subspecies studied had different chemical composition, when analysed by gas chromatography coupled to mass spectrometry with 1,8-cineole (56.98%), -pinocarveol (20.38%) and α-pinene (5.86%) being the major components of subsp. and spathulenol (25.09%), -cymene (21.20%), 1,8-cineole (10.74%) and α-pinene (8.93%) are the major components of subsp. These oils were evaluated for their insect antifeedant, nematicidal and phytotoxic activities. The biocidal tests showed that subsp was the most active against and . While, subsp. was not antifeedant. None of the investigated EOs were active against both and root-knot nematode. Moreover, the EOs extracted from these two subspecies showed a significant phytotoxic effect.

This study explored the chemical composition and synergistic interactions of essential oils (EOs) from Boenninghausenia albiflora collected from four locations (Boenninghausenia albiflora Harinagar EOs, BAHEO; Boenninghausenia albiflora Bhowali EOs, BABEO; Boenninghausenia albiflora Dunagiri EOs, BADEO and Boenninghausenia albiflora Munsyari EOs, BAMEO) in Uttarakhand, India, which focus on their pesticidal properties. To assess synergistic effects in pesticidal activities, EOs were combined in binary, ternary, and quaternary mixtures at equivalent ratios. The major compounds present in the EOs were identified.

Endophytic fungi produce a diverse range of bioactive secondary metabolites with potential applications in biopesticide development. This study investigates the nematicidal and antifeedant properties of ethyl acetate extracts from endophytic fungi isolated from wild Arabidopsis thaliana populations in Spain. The extracts were tested against the plant-parasitic nematode Meloidogyne javanica, and two common insect pests, Myzus persicae and Spodoptera littoralis.

Endolichenic fungi represent an important ecological group of microorganisms that form associations with photobionts in the lichen thallus. These endofungi that live in and coevolve with lichens are known for synthesizing secondary metabolites with novel structures and diverse chemical skeletons making them an unexplored microbial community of great interest. As part of our search for new phytoprotectants, in this work, we studied the endolichenic fungus sp.

The search for natural product-based biopesticides from endophytic fungi is an effective tool to find new solutions. In this study, we studied a pre-selected fungal endophyte, isolate YCC4, from the paleoendemism , along with compounds present in the extract and the identification of the insect antifeedant and nematicidal ones. The endophyte YCC4 was identified as sp.
