Abstract:

Yunan is located in a low-latitude plateau. With extreme high biodiversity level, Yunnan is often considered as a specimen library for the world. Chuxiong is located in the hinterland of central Yunnan, where is the biological convergence zone between the southern hot area and the northwestern frigid area. It has unique climate conditions, including seven agricultural climate types from the cold temperate zone to the tropical zone. It has rich agricultural resources, high biodiversity level and abundant resources of potential natural enemies. Coccinellids are important natural enemy resources in Yunan, with great potential in pest biological control. There are few investigations on natural enemy resources such as coccinellids in farmland in Chuxiong. In this study, the occurrence of coccinellids in the local red pear orchard was monitored for four consecutive years from 2018 to 2021, with habitat and climatic conditions also recorded. A total of 16 genera with at least 30 Coccinellidae species were recorded and identified, with manual survey and insect collection using Malaise trap. through the method of insect collection and manual investigation in Malaise trap. This dataset provides basic data on local coccinellid resources, which is a basis for analyzing coccinellid diversity, population dynamics, and occurrence pattern, and supports effective use of local natural enemy resources in agroecosystems.
