Abstract:

In order to provide basic information on control of bamboo forest pests, based on field investigation and literature review, the fauna of Pentatomomorpha was studied. The results showed that insects of Pentatomomorpha in Yunnan bamboo forests included 64 species of 9 families. Family Coreidae had the largest number of 29 species and Pentatomidae took the second place with 23 species. Most species markedly presented the characters of oriental realm, and only 5 species and 1 species respectively presented the characters of oriental-palaearctic realm and oriental-palaearctic-nearctic-ethiopian realm. In fauna of China, these species can be founded in southwest region, but 51.6% and 48.4% of them were distributed respectively in south and central of China. In fauna of Yunnan, 87.5% and 50% of these species were distributed in south margin of Yunnan middle-low mountain and strath and in southwestern Yunnan middle mountain and wide valley respectively. Few of them were distributed in other sub-district levels. The fauna of insect Pentatomomorpha in Yunnan bamboo forests markedly presented characters of both oriental realm and local region.
