| 中文摘要: |
| 赣南脐橙园蜘蛛已知13科38种。脐橙树冠层蜘蛛优势种有3种，其中草间钻头蛛(Hylyphantes graminicola)全年以5 - 6月及9 - 10月份的发生数量最大；斑管巢蛛(Clubiona deletrix)在7 - 10月份发生量较大，2 - 3月份的数量明显减少；鳞纹肖蛸(Tetragnatha squamata)在4月和12月份的种群数量较多，而6 - 9月份较少见到。地面层蜘蛛优势种有2种，其中草间钻头蛛的季节消长同样具有两个高峰期，但跨度较少，仅在6月份和10月份出现；拟水狼蛛(Pirata subpiraticus)种群数量在3月份达到最高峰，在12月份处于低谷。不同季节脐橙树冠层草间钻头蛛和斑管巢蛛的发生数量都与平均气温和日照时数呈显著或极显著正相关，而鳞纹肖蛸的季节发生数量与平均气温间为显著负相关；地面层拟水狼蛛的数量季节变动与相对湿度和降雨量间表现出极显著的正相关性。 |
| 英文摘要: |
| 13 families and 38 species of spiders were found in Gannan navel orange orchards. The dominant species were Hylyphantes graminicola, Clubiona deletrix and Tetragnatha squamata from navel orange canopies. Two main peaks of H. Graminicola population appeared from May to June, and from September to October. The numbers of C. deletrix population were more from July to October than from other months, and the numbers significantly reduced from February to March. During the examined months, the most numbers of T. Squamata were observed in April, and in December whereas very few individuals of the spider were seen from June to September. Hylyphantes graminicola and Pirata subpiraticus from grounds were the dominant spider species. The main peaks of H. Graminicola population appeared during June and October. The individual numbers of P. subpiraticus peaked in March and reduced to its lowest point in December. The significant positive correlations between seasonal changes of the numbers of H. graminicola, and C. deletrix, from navel orange canopies and mean temperatures or sunlights were found in this study. However, the correlation between seasonal changes of the numbers of T. squamata and mean temperatures was significantly negative. There were very significant positive correlations between seasonal variations in the numbers of P. subpiraticus from grounds in navel orange orchards and relative humidities, and rainfalls. |
