Abstract:In order to demonstrate the effect of in tensive 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 m ite 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 spiderm ite densities. No spiderm ite was found on tomato. In Autumn crop, the quantities of T. cinnabarinus on bean, eggp lant and cucum ber were pre tty low and the sp iderm ites per p lant were not higher than 13. 3. No spidermites were found on tomato or sweet pepper in p lastic shed or open fie ld. The intensive culture w as considered as acritical factor for decreasing the carm ine spiderm ites and the harmful weathe rcondition was also important.
