| 摘 要： | 在江西省赣州市章贡区蟠龙镇一个集中连片面积达32hm2且管理粗放的11年生"纽荷尔"脐橙园调查发现,脐橙园蜘蛛分属13科38种。脐橙园树冠层蜘蛛优势种有3种:草间钻头蛛Hylyphantes graminicola全年以5—6月及9—10月的发生数量最大;斑管巢蛛Clubiona deletrix在7—9月发生量较大,2—3月的数量明显减少;鳞纹蟏蛸Tetragnatha squamata在4月和11—12月的种群数量较多,6—9月较少见到。脐橙园地面层蜘蛛优势种有2种:草间钻头蛛的季节消长同样具有两个高峰期,但时间跨度较短,仅在6月和10月出现;拟水狼蛛Pirata subpiraticus种群数量在3月达到最高峰,在12月处于低谷。脐橙园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,鳞纹蟏蛸的发生数量则与平均气温间呈显著负相关;地面层拟水狼蛛的发生数量与相对湿度和降雨量间表现出极显著的正相关性。

| Abstract: | 13 families and 38 species of spiders were found in Gannan navel orange orchards.The dominant species in tree canopies were Hylyphantes graminicola,Clubiona deletrix and Tetragnatha squamata.Two main peaks of H.Graminicola population appeared from May to June,and from September to October.C.deletrix population was peaked from July to October,and significantly reduced from February to March.The peak of T.Squamata population was observed in April and December whereas the smallest population was observed from June to September.Hylyphantes graminicola and Pirata subpiraticus were the dominant spider species on the ground of the orchards.The main peaks of H.Graminicola population appeared in June and October.The population of P.subpiraticus peaked in March and bottomed in December.There was a significant positive correlation between the seasonal changes in the populations of H.graminicola and C.deletrix in navel orange canopies and the average temperatures and sunshine hours.In contrast,a significant negative correlation was found between the seasonal changes in the population of T.squamata and the average temperatures.There were very significant positive correlations between the seasonal variations in the population of P.subpiraticus on the ground of navel orange orchards and the relative humidity and precipitation. |
