Phytoplasmas are a group mollicute plant pathogens transmitted by insect vectors in the Hemiptera. Although vector species have been identified for many of plant diseases associated with phytoplasmas, little is known about the specificity of vector transmission. Some phytoplasma strains seem to be specifically transmitted, for example phytoplasmas in the Elm yellow group seem to be transmitted ...

Genetically modified maize tolerant to broad-spectrum herbicides may greatly alter weed flora composition, abundance and therefore affect organisms of higher trophic levels, including herbivore and detritivore arthropods and their natural enemies. This three-year study measured the effects on arthropods of an intensive use of broad-spectrum herbicides in comparison with one application of conve...

Potential insect vectors for transmission of oak leaf scorch caused by Xylella fastidiosa Wells et al., in pin and red oaks in New Jersey were surveyed by placing yellow sticky card traps in tree canopies and fogging with pyrethrin insecticide during 2002-2006. Thirty-seven Cicadomorpha species were collected from 20 genera in Membracidae, Cicadellidae, Aphrophoridae, and Clastopteridae. Of th...

A new species, Sangeeta sinuomacula Li, Dai & Li sp. nov., of tribe Agalliini of subfamily Megophthalminae (Hemiptera: Cicadellidae) is described and illustrated from Yunnnan Province of Southwest China. The new species is easily distinguished from other Sangeeta species by the aedeagal shaft with a pair of slender processes instead of lamelliform lateral expansions. A key to Sangeeta species a...

Four new species in two new genera of leafhoppers (Hemiptera, Auchenorrhyncha, Cicadellidae, Deltocephalinae) are described. All are associated with Xerophyta species (Velloziaceae, Pandanales), and are usually tended by ants. Observations and discussions of the ant associations are provided. The new leafhopper genera and species are: Xerophytavorus furcillatus gen.n & sp.n., from Malawi, and t...

Evacanthinae is a small subfamily in the Cicadellidae (Young, 1968; Zhang, 1990). It was redefined by Dietrich (2004), who included the tribes Evacanthini, Nirvanini, Balbillini and Pagaroniini in this subfamily. Recently, a new species was found in loaned material from Thailand, having several peculiar features worthy of establishing a new genus, described below. In addition, based on study of...

Sweta bambusanasp. n. (Hemiptera: Cicadellidae: Typhlocybinae: Dikraneurini), a new bamboo-feeding species, is described and illustrated from Guizhou and Guangdong of China. This represents the first record of the genus Sweta Viraktamath& Dietrich from China and the second known species of the genus. The new taxon extends the range of the genus Sweta, previously known only from northeast India ...

We review the world literature on leafhoppers (Cicadellidae) that have probed human skin, update the names presented in those published reports, and sort out which are original accounts and which are citations of previous reports (Table 1). We add 19 new records, representing five subfamilies, and at least 13 genera, all from Panama (Table 2). We speculate as to why these normally phytophagous ...

A new genus of Chinese Empoascini (Hemiptera: Cicadellidae: Typhlocybinae), Radicafurcus Qin & Zhang, gen. n. with one new species, R. breviprocessus Qin & Zhang, sp. n. from Sichuan Province (S.W. China) is described and illustrated. Baguoidea Mahmood 1967 is redescribed and a new species, B. yunnanensis Qin & Zhang, sp. n. is described from Yunnan Province (S.W. China). Two genera (Faiga Dwor...

Aboveground Hemiptera and Orthoptera communities were compared among three native and three restored mesic tallgrass prairies along the Platte River in central Nebraska to assess both the relative success of restored sites and the relationship between insect and plant communities. Hemiptera and Orthoptera were sampled using sweep nets in early June, mid-July, and mid-August 2000. Plant species ...
