Abundance and Consumption Rate of Glassy-Winged Sharpshooter (Hemiptera: Cicadellidae) on Peaches and Plums
Homalodisca vitripennis (Germar), the glassy-winged sharpshooter, is a primary vector of phony peach and plum leaf scald diseases caused by Xylella fastidiosa Wells et al. A survey of H. vitripenni...
Anatomy and histology of reproductive organs of female Homalodisca coagulata (Hemiptera : Cicadellidae : Proconiini), with special emphasis on categorization of vitellogenic oocytes
The anatomy and histology of female Homalodisca coagulata (Say) (Hemiptera: Ci-cadellida: Proconiini) reproductive organs is described using light microscopy. The reproductive organs of H. coagulat...
A nested-PCR assay for detection of Xylella fastidiosa in citrus plants and sharpshooter leafhoppers
Detection of Xylella fastidiosa in citrus plants and insect vectors. Chelex 100 resin matrix was successfully standardized allowing a fast DNA extraction of X. fastidiosa. An amplicon of 500 bp wa...
A Survey of Sharpshooters (Hemiptera: Cicadellidae) in Virginia Vineyards, a Region of Expanding Concern for Pierce's Disease
A survey was conducted during the 2006 and 2007 growing seasons to record the presence of sharpshooters (Hemiptera: Cicadellidae) vectors of Pierce's disease in Vitis vinifera L. growing regions of...
Background matching behaviour and pathogen acquisition: plant site preference does not predict the bacterial acquisition efficiency of vectors
Many insect-borne pathogens are heterogeneously distributed within their hosts: therefore, a vector's within-plant distribution may be a predictor of its exposure to pathogens. In this study, we se...
Biodiversity and ecology of potential vectors (Insecta: Hemiptera: Auchenorryncha) of Xylella fastidiosa Wells et al. in coffee plants of Puerto Rico
Xylella fastidiosa(Xf) is a xylem-limited bacterium that is the causal agent of coffee leaf scorch (CLS) in Central America. The purpose of this research was to survey potential vectors of Xf in pl...
Biology and biometry of sharpshooter Homalodisca coagulata (Homoptera : Cicadellidae) reared on cowpea
Stage-specific survival, growth, developmental biology, and biometry of the sharpshooter Homalodisca coagulata (Say) were studied in the laboratory under controlled conditions of 27 ± 1°...
Comparative dispersal of Homalodisca coagulata and Homalodisca liturata (Homoptera : Cicadellidae)
California's viticulture and ornamental industries have suffered significant losses since the introduction of Homalodisca coagulata (Say), an important vector of the Pierce's disease bacterium. A b...
Descriptions of eight new Acrogonia species from the Amazon region, including peculiar features of the female genitalia (Hemiptera: Cicadellidae: Cicadellinae: Proconiini)
Eight new species of the agriculturally important sharpshooter genus Acrogonia Stal, 1869 are described and illustrated from Brazil (one of them also recorded from Peru): A. amazonensis sp. nov. (s...
Diversity and abundance of leafhoppers in Canadian vineyards
Leafhoppers (Hemiptera: Cicadellidae) are pests of many temperate crops, including grapevines (Vitis species). Uncontrolled populations can induce direct and indirect damage to crops due to feeding...
EFFECT OF CONTACT AND SYSTEMIC INSECTICIDES ON THE SHARPSHOOTER BUCEPHALOGONIA XANTHOPHIS (HEMIPTERA: CICADELLIDAE), A VECTOR OF XYLELLA FASTIDIOSA IN CITRUS
The knockdown and toxic effects of insecticides of different chemical groups and modes of action registered for citrus in Brazil were investigated for effective control of Bucephalogonia xanthophis...
Effects of citrus and avocado irrigation and nitrogen-form soil amendment on host selection by adult Homalodisca vitripennis (Hemiptera : Cicadellidae)
Host plant water status is thought to influence dispersal of the xylophagous leafhopper Homalodisca vitripennis Germar, especially where plants are grown under high evaporative demand. Preference b...
