| 为探明河南南阳的空中昆虫群落结构，于2021-2023年利用探照灯诱虫器监测了夜间昆虫的种类和动态。3年共诱到昆虫10目42科112种，鳞翅目（13科71种）种类最多，其次为鞘翅目（10科17种）、半翅目（8科12种）；42科中，以夜蛾科（31种）为主，其次是天蛾科（10种）、螟蛾科（6种）。昆虫的群落结构存在年际差异，2021年恒有种为棉铃虫Helicoverpa armigera、劳氏粘虫Leucania loreyi、小地老虎Agrotis ipsilon和甘薯天蛾Agrius convolvuli；2022年和2023年恒有种均为棉铃虫和劳氏粘虫；亚洲玉米螟Ostrinia furnacalis、甜菜夜蛾Spodoptera exigua、雀纹天蛾Theretra japonica、铜绿丽金龟Anomala corpulenta、暗黑鳃金龟Holotrichia parallela、东方蝼蛄Gryllotalpa orientalis和油葫芦Cryllus testaceus为常见种；2021年的物种多样性、均匀度最高，Shannon-Wiener指数为2.0709，均匀度指数0.4406，2023年次之，Shannon-Wiener指数为0.7169，均匀度指数0.1544，2022年最低，Shannon-Wiener指数和均匀度指数分别为0.6507、0.1419。3年间，共诱到昆虫149 606头，2022年诱到昆虫60 737头，分别是2021年和2023年诱虫量的1.3倍、1.4倍；棉铃虫为当地第1大种群，3年虫量占总虫量的37.79%；其次为暗黑鳃金龟（20.58%）、铜绿丽金龟（10.91%）、甜菜夜蛾（7.82%）和亚洲玉米螟（3.55%），构成了当地的优势种群。本研究初步阐明了河南南阳地区的昆虫群落结构及种群发生动态，对指导当地害虫测报和防控工作提供了依据。 |

| In order to explore the community structure of airborne insect species in Nanyang City of Henan Province, the insect species and dynamics were monitored by searchlight trap at night from 2021 to 2023. A total of 112 species of insects, belong to 42 families, 10 orders, were trapped, with the most species belonging to Lepidoptera (13 families, 71 species), followed by Coleoptera (10 families, 17 species) and Hemiptera (8 families, 12 species). Among the 42 families, the dominant families were Noctuidae (31 species), followed by Sphindidae (10 species), Borellidae (6 species). There were significant inter-annual differences in the composition of the insect community structure, with the permanent species being Helicoverpa armigera, Laodelphax striatellus, Agrotis segetum and Manduca sexta in 2021, H. armigera and L. striatellus in both 2022 and 2023. Ostrinia furnacalis, Spodoptera exigua, Theretra japonica, Anomala corpulenta, Holotrichia parallela, Gryllotalpa orientalis and Cryllus testaceus were common species.The Shannon-Wiener index and evenness index were highest in 2021 (Shannon-Wiener index = 2.0709, evenness index = 0.4406), followed by 2023 (Shannon-Wiener index = 0.7169, evenness index = 0.1544), and lowest in 2022 (Shannon-Wiener index = 0.6507, evenness index = 0.1419). A total of 149 606 insects were trapped over the three years, with the highest trap-catching amount in 2022 (60 737 individuals), which was 1.3 and 1.4 times of 2021 and 2023, respectively. H. armigera was the dominant species locally, accounting for 37.79% of the total trap-catching amount of over the three years. Other dominant species included C. maculatus (20.58%), A. corpulenta (10.91%), S. frugiperda (7.82%), and O. nubilalis (3.55%). This study provides a useful contribution to understanding the insect community structure and population dynamics in Nanyang and provides guidance for local pest monitoring and control efforts. |
