Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.
