Complete mitochondrial genome of the corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae)

, 2023
The corn leafhopper, Dalbulus maidis, is the most important pest of maize (Zea mays) in the Neotropics, due to its efficiency in pathogen transmission and close evolutionary association with the crop. This host specialization has enabled D. maidis to spread with maize, from their center of origin in Mesoamerica to all tropical and subtropical America ...

Dose‐Dependent Effect of Plant Volatiles on the Oviposition Preference of the Corn Leafhopper Dalbulus maidis

Journal of Applied Entomology, Volume 150, Issue 4, Page 497-505, May 2026.
ABSTRACT Maize (Zea mays L.) is a major annual crop cultivated worldwide. In the Americas, the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae) is a key pest of this crop, causing direct damage to plants through phloem feeding and indirect damage by transmitting phytopathogens.

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.
