The objective of this work was to characterize the resistance of 50 cowpea (Vigna unguiculata) genotypes to Callosobruchus maculatus. A completely randomized design with five replicates per treatment (genotype) was used. No‐choice tests were performed using the 50 cowpea genotypes to evaluate the preference for oviposition and the development of the weevil. The genotypes IT85 F‐2687, MN05‐841 B...

The future of sustainable agriculture will increasingly rely on the integration of biotechnology with traditional agricultural practices. Most sustainable and environmentally acceptable control may be achieved using biocontrol agents due to the effort to reduce the use of agrochemicals and their residues in the environment and in food. Identifying, understanding and utilizing microorganisms or ...

Bacillus siamensis LDR was tested for its potential as a biocontrol agent against the phytopathogenic fungi Curvularia lunata BM and Ganoderma sp. TB4. Fermentation of B. production antifungal compound performed in modified Czapex-Dox broth using hanjeli ( Coix lacryma-jobi L.) starch carbon source. The inoculum 10 5 CFU/ mL, fermentation conducted up to 16 days. Antibiosis assay test activity ...

Little is known on aphid-induced emissions of volatile organic compounds (VOCs) from trees and particularly on their intraspecific variability in association with resistance traits. We compared VOC emissions from five peach cultivars (Prunus persica (L.) Batsch) and a wild relative (Prunus davidiana (Carrière) Franch) that differ in their level (susceptible/resistant) and type (antixenosis, ant...

This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes (amylases, lipases, proteases, and chitinases)...

Ectomycorrhizal fungal communities can be structured by abiotic and biotic factors. Here, we present evidence for community structuring by species interactions. We sampled ectomycorrhizas and forest floor seven times during a 13-month period. The presence of various ectomycorrhizal fungal species was determined for each sample, and species co-occurrence analyses were performed. For both ectomyc...

The aim of our study was to quantify changes in the activity of tyrosine decarboxylase (TYDC) within tissues of two cultivars of winter triticale: Triticosecale (Wittm. ex A. Camus), caused by grain aphid, and Sitobion avenae (F.). Obtained results show that Witon cv was less acceptable by S. avenae than Tornado cv and that antibiosis was an important part of the acceptability. The grain aphid ...
