棉花是我国主要的经济作物,我国是世界上植棉最大的国家之一。我国棉区分布辽阔,自然条件变化大,栽培制度复杂,棉虫种类繁多,而棉虫天敌的种类也很多,其中蜘蛛作为棉虫天敌加以研究和利用是最近几年的事情。几年来,随着棉虫天敌资源的调查和研究,对于棉田蜘蛛的种类和发生情况已积累了一定的资料。现在根椐新疆棉区,辽宁棉区、黄河流域棉区和长江流域棉区蜘蛛的种类和发生情况作初步分析,为保护和利用蜘蛛来控制棉虫提供依据。
Cotton is China’s major cash crop and China is one of the largest cotton-growing countries in the world. China has a vast cotton area with vast changes in natural conditions, complicated cultivation systems, a great variety of cotton insects, and many species of natural enemies of cotton insects. Among them, spiders have been studied and utilized as natural enemies of cotton insects in recent years. In recent years, with the investigation and research on natural enemies of cotton insects, some information has been accumulated on the types and occurrences of spiders in cotton fields. Based on the analysis of the types and occurrences of spiders in Xinjiang cotton area, Liaoning cotton area, Yellow River cotton area and Yangtze River cotton area, we provide the basis for the protection and utilization of spiders to control cotton insects.
