Habitat of the Corn Leafhopper (Hemiptera: Cicadellidae) During the Dry (Winter) Season in Mexico [PDF]

open access: yesEnvironmental Entomology, 2007
Although the corn leafhopper Dalbulus maidis (DeLong and Wolcott) is the most important vector of maize pathogens in Latin America, little is known about how and where it overwinters (passes the dry season), particularly in Mexico. The objectives of this study were (1) to monitor the abundance of D.

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

open access: yes, 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 ...
