供试砂叶螨采自河南省新乡县棉田(35°N)。该种叶螨对光周期的反应属于长日照型,临界光周期在20℃条件下为11.2小时。供试种群在短光照下诱发滞育后,不经低温处理,立即放于长光照30℃下,可全部解除滞育。高温对滞育率有降低的效应,每日10小时光照时间,在20、25和30℃时的滞育率分别为100％、69.2％和49.1％。 Test sand spider mite collected from Xinxiang County, Henan Province cotton field (35 ° N). The spider mite photoperiod response to the long-day type, the critical photoperiod at 20 ℃ for 11.2 hours. The test population in the short light induced diapause, without low temperature treatment, immediately placed in the long light at 30 ℃, all diapause can be lifted. The effect of high temperature on the diapause rate was reduced. The daily diapause time was 10 hours, and the diapause rates were 100%, 69.2% and 49.1% at 20, 25 and 30 ℃, respectively.
