Notes: Perissopneumon xyliae (Ayyar) [Hemiptera: Pseudococcidae] distribute mainly in chestnut areas in Yuxi, Qujing and Chuxiong, Yunnan Province, and is one of the main insect pests of chestnut tree. One generation occurs each year in Yimen, Yunnan. The nymph has three instars. They overwinter as the third instar nymph in bark crevices or on the base part of the tree trunks. High temperature, raining, predatory ladybirds, Eublemma amabilis and Microterys ericeri are the main natural factors manapulating its population dynamics.
