摘　　要：2000～2004年对云南省恙螨进行调查,发现云南省内恙螨192种,主要分布于中西部及中南部的热带及亚热带气候区,垂直高度多在1000m以下或1500～2500m范围。古北界种类有114种,占59%,东洋界种类较少为6%,35%的种类为跨界分布。中华纤恙螨Leptotrombidiumsinicum和小板纤恙螨L.scutellare为优势螨种。结合其他资料发现,该省广布种类10种,特有种5种,广宿主种及窄宿主种类均较多。少数螨种仅发现于3000m以上的高海拔温带气候区或500m以下的低海拔热带气候区。恙螨分布与地域、海拔及气候因素有关。We surveyed the fauna of chiggers in Yunnan Province and recorded 192 chigger species. Abundant species were found in the midwest and midsouth of Yunnan where the altitudes are about 1 500-2 500 m or under 1 000 m and the weather belongs to subtropical or tropic zone. The results showed that 59% of chigger species belong to Palaearctic species and 6% belong to Oriental species while 35% of chigger species occur in both Palaearctic Realm and Oriental Realm. Leptotrombidium sinicum and L. scutellare are two domain species. 10 chigger species are cosmopolitan species while 5 species are considered to be the endemic species of Yunnan on the basis of related literatures. There are many wide-host species and narrow- host species. A few species were only found in temperate zone where the altitude is beyond 3 000 m or under 500 rn in tropical zone. The distribution of chiggers is related to geographical location, altitude and climate.
