Sustainable control of Dalbulus maidis: A field study with entomopathogenic fungi

Entomologia Experimentalis et Applicata
AbstractSince its first report in Brazil in 1938, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae) has been considered a secondary pest for maize. However, this insect has now become a key corn pest and the main phytosanitary threat to production in Brazil due to its potential to transmit pathogens.

Insecticides Targeting Dalbulus maidis Influence Fall Armyworm Infestation in Bt and Non-Bt Maize Under Independent Field Conditions

International Journal of Agronomy
Spodoptera frugiperda (fall armyworm) is one of the most important pests of maize, causing severe foliar damage and reducing crop performance under high infestation levels. This study evaluated the effect of insecticides applied for the management of the

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 ...

Population dynamics of Dalbulus maidis in maize: effects of time of day and sampling technique [PDF]

Revista Brasileira de Entomologia
ABSTRACT Understanding the population dynamics of the corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae), the vector of pathogens responsible for maize stunt diseases, is essential for establishing an integrated management program for this pest. Defining an easy, fast, accurate and representative sampling method for D.
