| 为精准开展草原有害生物防控、保障草原生态安全,支撑生物多样性保护与农牧业绿色健康发展,昭通市通过草原有害生物专项普查,对草原植食性昆虫开展了系统标本采集与鉴定,共采集草原植食性昆虫标本9 614头,属于9目77科177属238种。经物种多样性、群落相似性分析,昭通市草原生态植食性昆虫优势类群为半翅目、鞘翅目、直翅目和鳞翅目;热性草丛植食性昆虫物种Shannon-Wiener多样性指数、Margalef丰富度指数和Simpson优势度指数均为最高,干热稀树草原Pielou均匀度指数最高,暖性草丛Shannon-Wiener多样性指数、Pielou均匀度指数、Simpson优势度指数均为最低,低地草甸Margalef丰富度指数最低;热性灌草丛与山地草甸、热性草丛、暖性灌草丛、人工草地,暖性灌草丛与干热稀树草原、人工草地,山地草甸与热性草丛、人工草地间植食性昆虫群落相似度较高。以期为草原有害生物灾害预警、生物多样性保护及农业和畜牧业绿色健康发展提供基础数据。 |

| To precisely implement the prevention and control of grassland pests, safeguard grassland ecological security, support biodiversity conservation and the green development of agriculture and animal husbandry, Zhaotong City conducted the systematic specimen collection and identification of grassland herbivorous insects through a special survey on grassland pests. A total of 9 614 herbivorous insects specimens were collected, belonging to 238 species, 177 genera, 77 families and 9 orders. Analyses of species diversity and community similarity revealed that the dominant groups of herbivorous insects in grassland ecosystems of Zhaotong City were Hemiptera, Coleoptera, Orthoptera and Lepidoptera. The thermic herbosa had the highest values of Shannon-Wiener diversity index, Margalef richness index and Simpson dominance
index; the dry-hot savanna showed the highest evenness index. The warm herbosa presented the lowest values of diversity, evenness and dominance indexes, while the lowland meadow had the lowest richness index. High community similarity of herbivorous insects existed between thermic shrub herbosa and mountain meadow, thermic herbosa, warm shrub herbosa and artificial grassland; between warm shrub herbosa and dry-hot savanna, artificial grassland; as well as between mountain meadow and thermic herbosa, artificial grassland. This study aims to provide fundamental data for the early warning of grassland pest disasters, biodiversity conservation, and the green and healthy development of agriculture and animal husbandry. |
