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 ...

Anagrus breviphragma Soyka Short Distance Search Stimuli
BioMed Research International, Volume 2015, Issue 1, 2015., 2015 Anagrus breviphragma Soyka (Hymenoptera: Mymaridae) successfully parasitises eggs of Cicadella viridis (L.) (Homoptera: Cicadellidae), embedded in vegetal tissues, suggesting the idea of possible chemical and physical cues, revealing the eggs presence.

Understanding maize genotype behavior under stunt complex pressure [PDF]
Ciência e AgrotecnologiaThe stunt complex, transmitted by Dalbulus maidis, has become one of the main maize diseases in recent years in Brazil and Latin America. Genetic resistance is one of the best ways to control and prevent plant diseases due to its efficiency, low ...

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.

Neotropical EntomologyAbstract The corn leafhopper, Dalbulus maidis (Hemiptera: Cicadellidae) and its associated corn stunt disease are considered the main production drawback currently faced by maize growers across South America, especially in Brazil. Native to Mexico and historically restricted to tropical America, the species has recently expanded its occurrence ...

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 ...
