Sex-Specific physiological strategies of Dalbulus maidis (Hemiptera: Cicadellidae) for surviving overwintering stress: Biochemical data

Abstract

Dalbulus maidis (Hemiptera: Cicadellidae), the principal vector of maize stunting pathogens in the Americas, is a major threat to maize (Zea mays L.) productivity, especially in Argentina. To cope with seasonal adversity, D. maidis relies on physiological adjustments that enhance stress tolerance and conserve energy. The objective of this study was to evaluate how proteins, lipids, soluble carbohydrates, and glycogen content, fatty acid profile, and phenoloxidase (PO) activity change in field-collected adults across summer, autumn, and winter.
