本文研究了神泽叶螨在茶树、梨、绣球和葡萄藤上的4个种群的发育成功率和产卵量。在供试的植物中，有14种是四个种群的共同寄主。茶树仅被茶树种群利用，绣球花植物仅被梨和绣球花种群利用。这三个种群都能利用kerria植物，而nanzu种群不能。在种群内杂交中，所有种群都产生雌性和雄性后代。三个种群（茶、梨和绣球）之间的种群间杂交是成功的。然而，雌性螨的Zurzu人口与男性从所有其他人群的生殖不兼容。因此，T.神泽由与茶相关的、与绣球相关的（梨和绣球）和避免Kerria（Kerria-avoiding）的种群组成。此外，已确定的是，雅鲁藏布江种群的生殖特征与其他种群不同。
The developmental success and the oviposition of the Kanzawa spider mite, Tetranychus kanzawai KISHIDA, on 44 species of plants were studied for four populations collected from tea, pear, hydrangea and kudzu vine. Of the plants tested, 14 were common hosts of the four populations. The tea plant was utilized only by the tea population, and the hydrangea plants only by the pear and hydrangea populations. These three populations could utilize the kerria plant, while the kudzu population could not. In intrapopulation crosses, all populations produced both female and male progeny. Interpopulation crosses among the three (tea, pear and hydrangea) populations were successful. However, female mites of the kudzu population were reproductively incompatible with males from all of the other populations. Thus, it was concluded that T. kanzawai consists of the tea-associated, the hydrangea-associated (pear and hydrangea), and the kerria-avoiding (kudzu) populations. In addition, the kudzu population was determined to differ in reproductive traits from the other populations.
