摘要
为了解新宾县境内自然保护区鳞翅目蛾类昆虫种群生长发育情况,2006-2021年调查了蛾类昆虫种类及数量,并对调查数据进行整理和分析。结果表明:共收集鳞翅目蛾类昆虫17科116种,其中夜蛾科的种数最多,占总种数的18.49%;天蛾科的个体数最多,占总个体数的16.81%。天蛾科、夜蛾科和舟蛾科的多样性指数分别为2.70±0.43、2.65±0.34和2.43±0.42,显著高于其他科(P<0.05);夜蛾科物种丰富度指数最高,为2.37±0.31;大蚕蛾科、天蛾科、夜蛾科、舟蛾科和波纹蛾科的均匀度指数较高,分别为0.89±0.15、0.90±0.17、0.86±0.15、0.88±0.17和0.94±0.19;优势种群分别为女贞尺蛾Naxa seriaria、花布灯蛾Camptoloma interiorata、银杏大蚕蛾Dictyoploca japonica,其中银杏大蚕蛾优势个体数最高,优势度为10.7%。当地蛾类的个体数与物种数变化趋势一致,均在7月达到峰值。新宾县自然保护区蛾类资源丰富,且蛾类群落稳定,具有极高的生态价值。
In order to solve the problem of the growth and development of moth population in Xinbin County Nature Reserve,the species and numbers of moth were investigated from 2006 to 2021,and the data were sorted and analyzed. The results showed that 116 species of moth from 17 families were collected,and the species of Noctuidae were the most,which accounted for 18.49% of the total species. The numbers of Sphingidae were the most,which accounted for 16.81% of the total numbers. The diversity index of Sphingidae,Noctuidae,Notodontidae were 2.70±0.43,2.65±0.34 and 2.43±0.42,respectively,which were significantly higher than those of other families(P<0.05).The species richness index of Noctuidae was the highest(2.37±0.31).The evenness index of Saturniica,Sphingidae,Noctuidae,Notodontidae and Thyatiridae were 0.89±0.15,0.90±0.17,0.86±0.15,0.88±0.17 and 0.94±0.19,respectively.The dominant populations were Naxa seriaria,Camptoloma interiorata,Dictyoploca japonica,and the number of dominant individuals of Dictyoploca japonica was the highest,and the degree of dominance was 10.7%. The number of local moths was consistent with the trend of species and reached the peak in July. The resources of moth are abundant in Xinbin County Nature Reserve,and its community is stable,which has high ecological value.
