Pest Management Science, 2022
AbstractBACKGROUNDThe corn leafhopper, Dalbulus maidis (Hemiptera: Cicadellidae), spreads maize stunt pathogens and requires timely and effective crop protection. We determined the interaction between maize phenology and the vector feeding/infection period by stunt pathogens with the residual efficacy of neonicotinoid insecticidal seed treatments ...

First Report of a Mastrevirus (Geminiviridae) Transmitted by the Corn Leafhopper
Plant Disease, 2022Maize striate mosaic virus (MSMV; genus Mastrevirus) was recently reported in maize plants in Brazil and also detected by metagenomic analyses in the corn leafhopper, Dalbulus maidis (DeLong & Wolcott). Although these findings suggested that D. maidis is a potential vector, no transmission studies have been performed.

Spatial and Temporal Distribution of Leafhoppers (Hemiptera: Cicadellidae) in a Corn Field
Neotropical Entomology, 2021Leafhoppers (Hemiptera: Cicadellidae) are phytophagous insects that transmit diseases and cause damage to this crop. Thus, the main goal of this study was to verify the spatiotemporal behavior of the leafhoppers Tapajosa ocellata (Osborn, 1926), Dechacona missionum (Berg, 1879), and Dalbulus maidis (DeLong, 1923) in a corn field in Igarapé-Açu ...

Concilium, 2023
Currently, the increasing productivity, garanee phytosanitary measures, and food security in plantations is a significant challenge. The potential of plant compounds in pests and diseases alternative control has been widely researched. This study is the first to investigate the use of the plant Morinda citrifolia L.(noni) for managing maize leafhoppers,

Maize Response to Corn Leafhopper (Homoptera: Cicadellidae) Infestation and Achaparramiento Disease
Journal of Economic Entomology, 1997To determine the effect that the timing of infestation of Dalbulus maidis (DeLong & Wolcott), a vector of 3 maize pathogens, known collectively as “achaparramiento,” has on stunt symptoms and maize yield, we conducted a field trial in the Sebaco Valley of Central Nicaragua.

Corn Stunt Spiroplasma in the Leafhopper Euscelidius variegatus
Journal of Phytopathology, 1987AbstractCorn stunt spiroplasma (CSS) multiplied in all leafhoppers Euscelidius variegatus injected with a culture of CSS, reaching titres of over 1x106 colony forming units (cfu) per insect and 2x104 cfu per salivary gland of each insect. CSS could be isolated from the haemolymph and the salivary glands at any time after injection. The growth of CSS in

Neotropical Entomology, 2017
The corn leafhopper, Dalbulus maidis (DeLong), is the most important leafhopper pest of maize, Zea mays, in the Americas. A survey of the diversity of its egg parasitoids was carried out in northwestern Argentina. During summer from 2004 to 2007, the samples were collected, using sentinel eggs of D.

Intraspecific competition and performance of Anagrus virlai parasitizing the corn leafhopper
Annals of Applied BiologyAbstractIntraspecific competition and avoidance of superparasitism are critical for biological control. In this study, we conducted behavioural and biological trials to assess intraspecific competition in the egg parasitoid Anagrus virlai, targeting the corn leafhopper Dalbulus maidis. Firstly, we investigated whether A.

Field Corn, Blackfaced Leafhopper and Maize Chlorotic Dwarf Disease Control, 1978
Insecticide and Acaricide Tests, 1979Abstract Dekalb 1214 was planted on May 11 near Godfrey, Ga. and on May 30 near Calhoun, Ga. Soil type was sandy-clay-loam at both locations. Two 0.5 acre blocks were planted in each location with a 36 and 38-inch row width at Godfrey and Calhoun, respectively.

Forewarning the seasonal dynamics of corn leafhopper and mollicutes through neural networks
International Journal of BiometeorologyThe corn leafhopper (CL), Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae), has become the most important corn pest in Brazil and other corn-producing countries. This highly efficient insect vector transmits corn stunting pathogens resulting in significant yield losses in corn fields. This study aimed to investigate the relationship between
