在日本西南部的和歌山县中部，研究了两种叶螨在三种不同寄主植物上的越冬生态。室内滞育诱导试验表明，豌豆和藜上二斑叶螨种群的滞育能力都很低，藜上二斑叶螨种群在整个冬季都能继续发育和繁殖。另一方面，T. kanzawai有一个遗传上强大的滞育能力，无论他们发生的寄主物种。然而，外地诱导的滞育女性的比例较低的人口发生在木通，万年青主机，有充足的新鲜叶片，整个冬季，比人口豌豆和Clerodendrum acuttomum，落叶树，这两个都恶化或落叶在冬季。滞育发生率低。quinata似乎是由于弱滞育诱导和/或较早的滞育终止的塑料反应充足的食物条件。在A. quinata，高比例的鸡蛋和未成熟的整个冬季，这表明整个冬季在这个地区的发展酸性繁殖是可能的，在充足的食物条件。
The overwintering ecology of two species of spider mites was studied on three different host plants in central Wakayama Prefecture, southwestern Japan. Laboratory diapause-inducing experiments showed that populations of Tetranychus urticae on peas and chrysanthemums both had a very low inherent capacity for diapause, and the population on chrysanthemums continued development and reproduction throughout the winter. On the other hand, populations of T. kanzawai had a genetically strong diapause capacity, regardless of the host species on which they occurred. However, the proportion of field-induced diapause females was lower in the population occurring on Akebia qninata, an evergreen host that had ample fresh leaves throughout the winter, than the populations on peas and Clerodendrum trichotomum, a deciduous tree, the leaves of both of which deteriorated or defoliated in winter. The low incidence of diapause on A. quinata seemed due to weak diapause induction and/or earlier diapause termination in the plastic response to ample food conditions. On A. quinata, high proportions of eggs and immatures remained throughout the winter, suggesting that development acid reproduction are possible throughout the winter in this area under ample food conditions.
