非滞育的生命周期对日本冈山县南部果园的荨麻科昆虫种群进行了研究。该螨只在果园二年生杂草上越冬，没有进入滞育，早春开始在杂草上数量增加，然后在出现时转移到其他杂草上。梨上螨类的发生始于5月上旬梨叶展开后数周，梨上螨类的种群是由梨基部杂草的迁飞者引起的。梨上的种群表现出两个明显的高峰，一个在6月，另一个在中秋。晚秋落叶后，该螨返回二年生杂草中越冬。
The life cycle of a non‐diapausingT. urticaepopulation was studied in a pear orchard in the southern part of Okayama Prefecture, western Honshû, Japan. The mites overwintered only on biennial weeds in the orchard without entering diapause, started to increase in number in early spring on them and then moved to other weeds as they emerged. The occurrence of the mites on pear began in early May several weeks after the unfolding of pear leaves and the population on pear was initiated by the migrants from the weeds around the base of pear trees. The population on pear showed two distinct peak occurrences, one in June and the other in mid‐autumn. After pear leaves dropped in late autumn, the mites returned to biennial weeds for overwintering.
