e0“This study investigates the efficacy of a specific type of hetero-chitooligosaccharide called partially deacetylated chitooligosaccharide enriched in d-glucosamine (DACOS; 85.6% deacetylation, an average molecular mass of 1092.52 Da), as a plant defense elicitor against the two-spotted spider mite, Tetranychus urticae Koch”
e3“Behavioral choice assays revealed that DACOS-treated leaves induced 73% mite repellency”

- Intervention effect DACOS reduced spider mite survival by 30% after 6 days.
- Intervention effect DACOS reduced cumulative spider mite fecundity by 41% after 6 days.
- Intervention effect Systemic effects of DACOS were strongest at 160 ppm.
- Intervention effect DACOS had no direct acaricidal effect.
- Observation Metabolic profiling of DACOS-treated plants showed enriched monoterpenoid and alpha-linolenic acid pathways that produce repellent volatile organic compounds.
