Abstract Oligonychus litchii Lo & Ho was commonly found in mango orchards in Tainan City, and was found alone or dominate in some orchards. However the population of this mite in the mango orchard in Pintung County is still low or rare. It is also commonly found in pear orchards in Tungshih Distrrict, Taichung City, and was found alone in most surveyed orchards. Eutetranychus africanus (Tucker) was also collected in two pear orchards. This species is recorded in Taiwan for the first time.
