山黄皮上柑橘木虱发生调查初报

Preliminary reports on host-vector relationship between Clausena anisum-olens and Citrus psylla

【目的】明确山黄皮上是否有柑橘木虱为害,为开展山黄皮是否是柑橘木虱寄主研究奠定基础。【方法】采用面上调查和实地调查相结合的方法,对地处广西桂南的龙州县、宁明县及广西现代农业技术展示中心(南宁)的山黄皮、黄皮、柑橘上柑橘木虱发生情况进行调查。【结果】被调查的12个点中,广西现代农业技术展示中心的山黄皮上发现有柑橘木虱,其他调查点山黄皮上未发现有柑橘木虱。【结论】山黄皮上有柑橘木虱,但山黄皮是否是柑橘木虱的寄主尚待研究。

[Objective]The present experiment was conducted to determine the damages of Clausena anisum-olens caused by Citrus psylla in order to find out host-vector relationship amongst Clausena anisum-olens and Citrus psylla.[Method]The field survey was undertaken to investigate the current status of Citrus psylla occurrence on Clausena anisum-olens,Clausena lansium,Citrus limon and citrus trees of Longzhou,Ningming in Guangxi and the Guangxi Exhibition Centre of Modern Agriculture Technology（Nanning） .[Result]Except the Clausena anisum-olens trees in the Exhibition Centre of Guangxi Modern Agriculture Technology,no other incidences of Citrus psyalla occurrence on Clausena anisum-olens were observed at 11 investigation sites.[Conclusion]The presence of Citrus psylla on Clausena anisum-olens trees was established,but relationship with Clausena anisum-olens as host plant for Citrus psylla still needs further investigations.
