摘　　要：为了明确集约化栽培管理模式对蔬菜上朱砂叶螨Tetranychus cinnabarinus(Boisduval)的种群数量及动态的影响,2008年在中国农科院蔬菜花卉所塑料棚和露地春、秋茬5种蔬菜上,调查了该螨的种群动态。结果表明,6月中旬春棚的朱砂叶螨种群数量达到高峰期,6月下旬后则明显下降;露地春茬菜豆、茄子、甜椒和黄瓜于6月上旬始见叶螨发生,有螨株率比单株螨量增长迅速,番茄上未发现叶螨。塑料棚和露地秋茬菜豆、茄子和黄瓜上朱砂叶螨发生数量低于13.3头/株,番茄、甜椒寄主上均未发现叶螨为害。分析认为,集约化栽培措施是制约朱砂叶螨种群发生数量的关键因素,降雨和高湿等不良的气象条件也有重要影响。In order to demonstrate the effect of intensive culture on carmine spider mite,Tetranychus cinnabarinus （Boisduval）,the population dynamics on bean,eggplant,sweet pepper,cucumber and tomato in plastic shed and open field in Beijing area were investigated in 2008. The results showed that carmine spider mite populations reached the peak in the middle of June,and decreased at the end of June in greenhouse. The carmine spider mite on bean,eggplant,sweet pepper and cucumber happened at the beginning of June in the open field in spring crop and the ratio of plants with mites increased rapidly than the spider mite densities. No spider mite was found on tomato. In Autumn crop,the quantities of T. cinnabarinus on bean,eggplant and cucumber were pretty low and the spider mites per plant were not higher than 13.3. No spider mites were found on tomato or sweet pepper in plastic shed or open field. The intensive culture was considered as a critical factor for decreasing the carmine spider mites and the harmful weather condition was also important.
