Simaonukia, a new leafhopper genus of Evacanthini (Hemiptera, Cicadellidae, Evacanthinae), and a new species, Simaonukia longispinus sp. n. from Yunnan, China are described.

Systemic insecticides and application methods were evaluated in two trials that began in 2005 and 2006 for control of potato leafhopper (Empoasca fabae [Harris]) on four red maple (Acer rubrum L.) cultivars and rated annually through 2007. Treatments evaluated in this study included surface drenches of imidacloprid plus cyfl uthrin (Discus) or imidacloprid plus bifenthrin (Allectus SC), clothia...

BACKGROUND Spiroplasma citri is a wall-less bacterium that colonizes phloem vessels of a large number of host plants. Leafhopper vectors transmit S. citri in a propagative and circulative manner, involving colonization and multiplication of bacteria in various insect organs. Previously we reported that phosphoglycerate kinase (PGK), the well-known glycolytic enzyme, bound to leafhopper actin an...

Two new species of endemic Chinese leafhopper genera (Flexocerus Kuoh & Fang and Idioceroides Matsumura), F. sinuatus sp. nov. and I. petaliformis sp. nov. are described and illustrated. Keys to species for both genera are provided.

The Colorado potato beetle, Leptinotarsa decemlineata (Say) Order Coleoptera and the potato leafhopper, Empoasca fabae (Harris) Order Homoptera, are the major insect pests of potato in eastern North America. In two years of field trials, we compared the effectiveness of three pest management options for the control of Colorado potato beetle and potato leafhopper: natural host plant resistance (...

The two leafhopper species in the genus Parazyginella Chou & Zhang from China are reviewed and illustrated including one new species, Parazyginella tianisp. n. whichis described. A key to separate males of the two species is provided.

The species of the Oriental leafhopper genus Subulatus Yang & Zhang are reviewed. A new species, Subulatus flavidus sp. nov., from Yunnan Province, China is described and a key to all known species of Subulatus is provided. 

Two new species of the empoascine leafhopper genus Membranacea Qin & Zhang are reported from China: Membranacea hubeiensis Yu & Yang, sp. n. and Membranacea stenoprocessa Yu & Yang, sp. n.. A key to distinguish all species of the genus is provided.
