摘　　要：为掌握江苏省大丰区昆虫本底资源状况,促进当地生物多样性的保护,2019年4—8月集中对大丰区昆虫资源进行调查。此次共采集到昆虫标本6614号,隶属于10目85科231种,其中鞘翅目种类最多,占总数的22.51%,蜻蜓目个体数量最多,占总数的20.79%。生物多样性分析显示,大丰区城市公园绿地和珍禽自然保护区南侧昆虫多样性指数最高。以蝴蝶类群进行区系分析显示,大丰区蝴蝶主要以广布种为主,东洋种和古北种相互渗透。大丰区的昆虫构成中,农林害虫最多,有113种,占总数的48.92%,天敌昆虫也较为丰富,有68种,占总数的29.44%。大丰区作为候鸟迁徙通道的重要中转站,是生物多样性的富集区,掌握其昆虫资源的多样性对于该区域生物多样性保护十分重要。In order to obtain the status of insect resources in Dafeng District,Jiangsu Province,and promote the protection of local biodiversity,a survey of insect resources in Dafeng District was conducted from April to August 2019.A total of 6614 insect specimens were collected this time,belonging to 231 species of 85 families and 10 orders,of which Coleoptera had the largest number in terms of species,accounting for 22.51% of the total,and Odonata had the largest number in terms of individuals,accounting for 20.79% of the total.The biodiversity analysis showed that the urban parks of Dafeng District's urban area and rare bird nature reserves had the highest insect diversity index.Faunal analysis based on butterfly groups showed that the butterflies in Dafeng District were predominantly broad-spread species,while the Oriental realm and Palaearctic realm species infiltrate each other.Among the insect composition in Dafeng District,agricultural and forestry pests were the largest,with 113 species,accounting for 48.92% of the total,and natural enemy insects were also abundant,with 68 species,accounting for 29.44% of the total.Dafeng District was an important transit station for migratory bird habitats and an area of biodiversity.Mastering the diversity of its insect resources was very important for the protection of biodiversity in the region.
