[Objectives]  To investigate the species and population dynamics of leafhoppers in jujube orchards in Yanchuan county, Shaanxi province in order to identify potential vectors of jujube witches’ broom (JWB), and thereby provide a theoretical basis for preventing the spread of this disease in northern Shaanxi. [Methods]  The species and population dynamics of leafhoppers in jujube orchards were investigated using yellow sticky traps, and species carrying JWB phytoplasma 16S rDNA were identified with PCR. [Results]  A total of 11 leafhopper species were captured, including Zygina discolor Horváth, Arboridia zhenyuana Song & Li, Singapora shinshana Matsumura, Austroasca mitjaevi Dworakowska, Kolla paulula Walker, Batracomorphus allionii Turton, Hishimonus hamatus Kuoh, Orientus ishidae Matsumura, Platymetopius henribauti Dlabola, Platymetopius obsoletus Signoret, and Reticuluma testacea Kuoh. The most common species captured were Z. discolor, B. allionii, and A. mitjaevi, which comprised for 49.64%, 21.82%, and 11.76%, respectively, of all leafhoppers captured. These three leafhoppers are the dominant species in jujube orchards. Leafhoppers are most common in Yanchuan jujube orchards from late April to early November. There are three occurrence peaks for Z. discolor, two for B. allionii and R. testacea adults, and only one, or no obvious peak, for the other monitored species. PCR indicated that a high proportion (> 80%) of Z. discolor and H. hamatus carried JWB phytoplasm, followed by S. shinshana, R. testacea, and O. ishidae (50%-68%) and B. allionii (39%). No phytoplasma were detected in adult K. paulula. [Conclusion]  Leafhopper species were abundant in Yanchuan jujube orchards and a high proportion of several common species were infected with JWB phytoplasma. Potential vectors of JWB should be effectively controlled based on their species-specific population dynamics, which will help break the chain of transmission and delay the spread of JWB in the jujube growing area of northern Shaanxi.
