| 中文摘要: |
| 采用吸虫器法, 系统调查了辽宁盘锦稻区杂草地与稻田中蜘蛛种类及优势度情况, 以及蜘蛛优势种、种类数和个体数的年度变化趋势。结果表明, 杂草地全年共有4个优势种, 为草间钻头蛛、横纹金蛛、三突花蛛和黄褐新圆蛛。水稻生长期内稻田共有3个优势种, 为草间钻头蛛、横纹金蛛、粽管巢蛛。杂草地与稻田中优势蜘蛛数量与蜘蛛个体数量变化趋势大体一致, 均为缓慢上升趋势, 最高峰均在8月中下旬, 分别达到139头/m2和155头/m2, 至水稻成熟期迅速减少。水稻插秧前与收割后, 杂草地蜘蛛种类数最高值分别为23种/10 m2和34种/10 m2, 均高于稻田; 稻田中蜘蛛种类为缓慢增加, 至收割前达到峰值23种/10 m2。两个生境蜘蛛种群的相似性系数为0.666 7。 |
| 英文摘要: |
| The annual seasonal fluctuation of spider species abundance and dominance in paddy field and adjacent habitat was investigated with the suction sampler. Throughout the year, there were 4 dominant spider species in weed habitat, such as Hylyphantes graminicola, Argiope bruennichi, Misumenops tricuspidatus and Neoscona doenitzi, while there were 3 dominant spider species in paddy field, such as H. graminicola, A. bruennichi and Clubiona japonicola. The seasonal fluctuation pattern of dominant spiders and density in these two habitats were similar, with the peak value of 139 individual/m2 and 155 individual /m2, respectively. The abundance of spider species in weed habitat was more than that in the paddy field, and the peak abundance of spider species pre-and post-planting of rice was 23 species/10 m2 and 34 species/10 m2, but 23 species/10 m2 in paddy field in rice growing season. The similarity coefficient of spider populations is 0.666 7 on these two habitats. |
