通过对稻田各蜘蛛和害虫空间生态位的研究发现 ,空间生态位宽度随季节而变化 ,狼蛛的生态位宽度值逐渐变大 ;肖蛸两头高中间低 ;微蛛在 7月下旬最大 ;球腹蛛在 8月下旬 9月上旬最大。各类群的数量是影响该类群空间生态位的重要因素。空间生态位具有明显的日节律 ,狼蛛在 7～ 8月份以中午最宽 ,微蛛变化不大 ;肖蛸在 7～ 8月份下午的生态位宽度值大于上午 ,9月份则上午大于下午 ;球腹蛛 7～ 8月份以上午为最大 ;跳蛛下午大于上午。不同种类农药在一天中不同时间施用对各类蜘蛛存活率及捕食功能的影响不同 ,杀虫双上午用药对蜘蛛集团的捕食功能减退率影响较小 ,甲胺磷则相反
Through the study on the spatial niche of spiders and pests in paddy fields, it was found that the width of niche breadth varied with the seasons, and the niche breadth of tarantulas became larger; Spider spider in late August the largest in early September. The number of each group is an important factor affecting the spatial niche of the group. The spatial niche had obvious rhythm of day. The tarantula was the broadest at noon from July to August, while the micro-spider had little change. The niche breadth of Xanthium sibiricum in the afternoon of July-August was greater than that of the morning, and that of September was greater than that of the afternoon in the morning. Spider spider 7 to August to the morning of the largest; jumping spider afternoon than in the morning. Different types of pesticides applied at different times of the day had different effects on the survival rate and predation function of all kinds of spiders. Insecticidal double-morning drug had little effect on the decline of predation function of Spider Group and methamidophos
