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.

Effect of the Oviposition Period and Age of the Females of Dalbulus maidis (Hemiptera: Cicadellidae) in the Emergence of Egg Parasitoids [PDF]

Florida Entomologist, 2020
Little is known about the effect of adult leafhopper age and its oviposition period on the emergence of egg parasitoids. The objective of this study was to determine the emergence rate of egg parasitoids that attack eggs of the corn leafhopper, Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae), when the adult corn leafhopper differs in age and is ...

Observations on the Life Cycle of Dalbulus maidis on Three Plant Species

The Florida Entomologist, 1970
Dalbulus maidis (Delong and Wolcott) preferred corn to gamagrass or Johnsongrass for adult survival and oviposition. Incubation periods for eggs in these plants were approximately the same. Developmental period from eclosion to adult was shorter on corn than on gamagrass, whereas nymphs did not survive on Johnsongrass.
