| 摘 要： | 研究旨在应用昆虫数学生态学方法,查明武威地区苗圃地灯下蛾类昆虫种类及其时序动态,掌握研究区蛾类昆虫多样性特征,为区域昆虫多样性调查和害虫的科学防控提供参考。以武威市国家杨树樟子松良种基地为调查监测地,利用诱虫灯对武威地区苗圃地灯下蛾类昆虫进行调查,并对其昆虫群落多样性特征及时序动态进行分析。诱集到的5154头蛾类昆虫分属于鳞翅目9科54种,其中夜蛾科为优势类群（共38种）,天蛾科次之（共5种）。群落多样性指数、丰富度指数与物种数、个体数变化趋势一致,4月较低、6—7月最高;优势度指数4—5月最高、7月最低;均匀度指数在6—8月较稳定,4、9月波动较大。武威地区苗圃地蛾类昆虫群落较丰富,以夏季最为集中。

| Abstract: | The purpose of this study is to find out the species and temporal dynamics of moths under ultraviolet ground lamps in nurseries in Wuwei area by using the method of insect mathematical ecology, so as to grasp the diversity characteristics of moths in the study area and lay a foundation for regional insect diversity investigation and scientific pest control. Wuwei National Poplar and Pinus sylvestris var. mongolica Improved Seed Base was used as investigation and monitoring site. With insect trap lamps, moth insects under lamps in nurseries in Wuwei area were investigated, and their insect community diversity and temporal dynamics were analyzed. The results show that 5154 moths are divided into 9 families and 54 species. Noctuidae is the dominant group which includes 38 species, and Sphingidae comes the second with 5 species. The Shannon-Winner diversity index and Margalef richness index are coincident with the changes of taxa and individuals, which are lower in April, and reach the highest in June and July. Berger-Parker dominance index is the highest from April to May and the lowest in July. Pielou evenness index is relatively stable in June, July and August, and fluctuates greatly in April and September. In conclusion, the moth communities in nurseries in Wuwei area are rich, and are most concentrated in summer. |
