Effect of agro‐ecological landscape on the distribution of Culicoides obsoletus in northeast China

Abstract

BACKGROUND Culicoides obsoletus is an important pest for animal husbandry. In the world, it is a major vector of bluetongue disease, which has been added to the list of Class A Animal Diseases by the World Organization for Animal Health (OIE) and must be reported in the event of an outbreak. Although numerous studies on Culicoides sampling in farms exist, the distribution of C. obsoletus in different landscapes remains unclear. RESULTS This study aimed to assess the effect of landscape type on the distribution of C. obsoletus. Samples were collected using light traps during spring and fall. The effect of landscape type on the distribution of C. obsoletus samples was measured by the maximum entropy model (MaxEnt). Results show that C. obsoletus mainly appears in forests and pastures. CONCLUSION Our results may provide references for controlling the C. obsoletus population and provide suggestions of other areas that may also face the challenge of bluetongue.

Construction of Ecological Landscape Environment in Guanzhong Traditional Villages from the Perspective of Rural Revitalization

“…It shows that it is very important to protect the integrity of the landscape pattern, the regionality of the architectural style, and the preservation of historical elements for villages. However, the implementation degree of the C22 supervision and management system, the suitability the of C12 street and lane space scale, the richness of the C20 intangible culture, and the cleanliness of C24 environmental sanitation facilities are all low, which indicates that there is not enough attention in supervision and management and intangible cultural inheritance of traditional villages, mainly focusing on the physical landscape [15].…”
