Urbaneja-Bernat, P., Schulze-Sylvester, M., Syropoulou, A., Müller, C., Schweiger, R., & Becker, C. 2026 Elevated CO2 and water limitation alter the primary metabolite composition of mealybug honeydew, reducing parasitoid fitness. Journal of Agricultural and Food Chemistry 74, 20261−20271

Keywords:

  • climate change
  • ecology
  • honeydew
  • host
  • natural enemies

    • Notes: The questions addressed in this study were (i) whether and how eCO2 and water limitation alter the honeydew quantity and quality of P. ficus feeding on grapevine, i.e., honeydew fresh mass, dry matter content, density, and primary metabolites including sugars and amino acids, and (ii) whether these changes impact the honeydew nutritional value for A. vladimiri and, consequently, its fitness, as measured by longevity and fecundity. https://doi.org/10.1021/acs.jafc.5c17227
