Insects represent a major group of vectors of Rice yellow mottle virus (RYMV). This study aimed at identifying the main entomofauna transmitting RYMV to rice crop in Benin. Therefore, the transmission ability of 13 insect species was tested during the rice vegetative stages. These species belong to ...

Gyponinae includes leafhoppers species and has been little studied in relation to its potential as a vector for microorganisms and their occurrence in crops. The objective of this study was to realize the faunistic analysis and know the population fluctuation of Gyponinae species (Hemiptera:...

Insects in the Cicadellidae and Delphacidae families, common in grasses, are an important group of vectors of viruses and mollicutes, which cause diseases in several plant species. The goal of this study was to evaluate the abundance and species richness of Cicadellidae and Delphacidae and the...

Curly top, caused by Curtovirus spp., is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. The insecticide seed treatment Poncho Beta has proven to be effective in controlling curly top in sugar beet but was only evaluated under light to moderate...

In August 2009, yellowing, upward curling of leaves, and stunted growth were observed on 15 to 40% of dry bean (Phaseolus vulgaris) plants in each experimental fields in Zacatecas, Mexico. Symptoms and presence of bean leafhopper (Circulifer tenellus) in affected fields suggested an infection by...

The capacity to predict the geographic distribution and relative abundance of invasive species is pivotal to developing policy for eradication or control and management. Commonly used methods fall under the ambit of ecological niche models (ENMs). These methods were reviewed and shortcomings...

During surveys conducted in 2010, Orientus ishidae, known as the mosaic leafhopper, was found in northern Italian (Varese) vineyards affected with flavescence doree (FD) disease. A total of 75 yellow sticky traps were used to capture 251 O. ishidae specimens. Total DNA was extracted from 32 of 251...

The glassy-winged sharpshooter, Homalodisca vitripennis (Germar), is an invasive pest that has spread across the southern and western United States. H. vitripennis is highly polyphagous and voracious, feeding on at least 100 plant species and consuming up to 100 times its weight in xylem fluid...

A field survey covering the major cereal-production areas of Syria was conducted during May 2009. A total of 938 wheat and 971 barley samples with typical symptoms of viral infection were collected from 45 wheat and 58 barley fields. Serological tests showed that Wheat dwarf virus (WDV) was...

Leafhoppers (Hemiptera: Auchenorrhyncha: Cicadellidae) account for more than 80% of all "Auchenorrhynchous" vectors that transmit phytoplasmas. The leafhopper populations in two almond witches'-broom phytoplasma (AlmWB) infected sites: Tanboureet (south of Lebanon) and Bourj El Yahoudieh (north of...
