摘要
针叶小爪螨寄生于多种针叶树。该螨以两性生殖为主，雌雄比为2．5：1，单雌产卵量35～50粒。在龙井1年发生6代，多以卵在松枝上越冬。5月上旬越冬卵开始孵化，9月份全部进入越冬状态。其个体发育与温度关系密切，活动与取食有明显的喜光性和趋嫩性，一天中以09：00-16：00活动频繁。
Oligonychus ununguis lives in various conifers. They produce mainly by amphigenesis, and the ratio of female and male is 2.5： 1, which lay 35 - 50 eggs per female. There are six generations in Longjing during one year, and eggs mostly overwinter in branches of pine. Egg hatches in early May, and hibernation generally begins in September. Ontogeny is closely related with temperature, and the activity and feeding are obviously depended on light and twigs. During 09：00- 16：00 is active time of a day.
