黑翅土白蚁对福建柏的危害及发生特征

关键词：
福建柏;黑翅土白蚁;时间格局;空间格局;
摘  要：
在福建柏主栽区的9个工区调查黑翅土白蚁的危害与发生特征.结果表明:（1）福建柏主栽区9个工区均有不同程度的黑翅土白蚁发生,其中,安溪下镇工区的受害率最高（56.7%）;（2）上坡位的福建柏受害率高于中、下坡位;（3）黑翅土白蚁通过修筑蚁道接近福建柏,并先啃食地径部位,随后扩散到根部和树冠等部位,导致植株衰弱甚至死亡;（4）1 a生福建柏受害率显著高于2、4 a生福建柏;（5）黑翅土白蚁的危害高峰期为5—9月;（6）黑翅土白蚁对1 a生福建柏的不同家系没有明显的选择偏好性.

摘  要：
In the main planting area of Fokienia hodginsii, the infestation and occurring pattern of Odontotermes formosanus was investigated in detail to provide a reference for the integrated pest management. The results were presented as follows:(1) Damage degrees of F.hodginsii varied among main planting areas across Fujian Province, and peaked in the Xiazhen work area of Anxi County.(2) The damage rate of F.hodginsii was significantly higher in the upper slope than those in the middle and lower slopes.(3) O.formosanus approached F.hodginsii by building mud channel; the infestation started with lower stem and then spread toward root and the upper stem, leading to feeble and even dead trees.(4) The damage degree of one-year-old F.hodginsii infested by O.formosanus was significantly higher than that of perennial ones.(5) O.formosanus infestation peaked from May to September.(6) O.formosanus did not show specific preference for any provenance of one-year-old F.hodginsii.
