[ Method] Using sampling plot investigation method, the species composition and population structure of ladybugs in Baihualing of Gaoligong Mountain were surveyed. [ Result ] A total of 3 218 ladybugs specimens had been collected, belonging to 5 subfamilies, 20 genera, 56 species. Two spe- cies were new records for Yurman Province. The species and number of Coccinellinae were the greatest, followed by Epilachninae and Aspidimerinae, while Coceid- ulinae and Scymninae were the least. The dominant species were Coccinella septempunctata L., Harmonia eucharis （ Mulsant ） and Afissula hydrangeae Pang et Man. [ Conclusion] The study laid foundation for further study on ladybugs in Baihualing of Gaoligong Mountain.展开更多

[ Meth- od] The seasonai change rule of community diversity of ladybugs in Baihualing of Gaoligeng Mountain was studied during April 2008 to January 2009. [ Result ] The species diversity of ladybugs from April to June in 2008 gradually increased, which reached the peak in June and September, and then declined gradually after October. The community similarities of ladybugs in the months with less difference in temperature and rainfall were relatively high. [ Conclusion] The study pro- vided theoretical basis for the further study on ladybugs in Baihualing of Gaoligong Mountain.展开更多

[ Method] The community and diversity of ladybugs in vertical level in Baihualing of Gaoligong Mountain was investigated. [ Result] The species diversity of ladybugs was the greatest at the medium altitude level （ 1 600 - 1 900 m）, which gradually decreased in low and high altitude. The greater the altitude span was, the lower similarity between communities of ladybug was, and vice versa high; the similarity of ladybug communities in protected areas was relatively higher, while it was relatively lower in fanning areas. The altitude level of 1 600 - 1 900 m with the highest community diversity of ladybugs shared low similarity with the community diversity of ladybugs in other altitude levels. [ Conclusion] The study provided theoretical basis for the further study on ladybugs in Baihualing of Gaoligang Mountain.展开更多
