辽河三角洲稻区田间自然蜘蛛种群的保护技术探索

Exploration of Protection Technology on Spider Population in Rice Planting Area of Liaohe River Delta

蜘蛛是稻田生境中优秀的捕食者,食量惊人,在水稻害虫生物防治中发挥着重要的作用,同时,蜘蛛的生存繁衍对维护整个稻田生态系统的稳定性具有较大的影响。在辽河三角洲稻区蜘蛛优势种有横纹金蛛、粽管巢蛛和草尖小黑蛛。创建有利于蜘蛛生存的栖息环境并适时补充蜘蛛食源,同时严谨施用药剂,逐渐探索出保护田间自然蜘蛛种群的技术措施。

As predator in paddy habitat, spider can prey on moreharmful insects so it play an important role in Biological control of rice insect pests, at the samen time, survival and procreation of spider had more affection to maintain the stabilityof the paddyfield ecosystem. wasp spider, clubiona japonicola and Lipaphis erysimi were dominant species in rice planting area of Liaohe River delta. Build a good living condition for spider and add food source timely,selected drugs rigorously, it can progressively explore technical maneuver for protecting spider population.
