Abstract:
[Objectives] To identify
the empoascine species damaging kiwifruit in Meixian county, Shaanxi province
and describe the polymorphism of the dominant species. [Methods] A sweep net was
used to collect specimens and a camera to take habitat photos in the field.
Microscopes were used to observe morphological characters and main diagnostic
features were photographed. [Results] Three species were identified, Membranacea
unijugata Qin & Zhang, 2011, Empoasca (Empoasca) hiromichi (Matsumura, 1931) and Empoasca (Empoasca) matsudai Dworakowska, 1972. A total of
685 specimens were collected, of which Membranacea
unijugata accounted for
81.75% of all specimens and Empoasca (Empoasca) hiromichi and Empoasca (Empoasca) matsudai for 17.66% and 0.58%, respectively. The M. unijugata specimens included 88 dark-colored males and 472 light-colored
individuals (13 males and 459 females). [Conclusion] The dominant empoascine species damaging
kiwifruit in Meixian county, Shaanxi province is M. unijugata, the adults of which are polymorphic. Further
investigation is required to identify other empoascine species damaging
kiwifruit in China.
