| 为探究化学防治对皖南烟区烟叶上蜘蛛群落多样性的影响, 于2021年4月至7月采用目测法和拍打振落法对未进行化学防治田(抑芽剂)和化学防治田(抑芽剂和化学农药)烟叶上的蜘蛛进行了调查?共记录鉴定未化学防治田蜘蛛(12科40种943头)和化学防治田蜘蛛(11科32种693头)的数量为1 636头, 分属于13科44种?蜘蛛的卵囊附着在烟叶的叶尖和叶缘, 6月下旬达到峰值?烟田蜘蛛群落的时间动态和多样性指数变化说明, 未化学防治田和化学防治田蜘蛛的个体数量均在5月中旬达到最大, 但丰富度呈现一定的波动, 多样性指数和均匀度指数在6月底到7月初达到最大, 但优势集中性指数在这期间最小?两种类型的烟田中草间钻头蛛Hylyphantes graminicola和食虫沟瘤蛛Ummeliata insecticeps均为优势种?通过对两烟田蜘蛛群落多样性的比较, 结果表明, 未化学防治田比化学防治田的蜘蛛群落更具有稳定性, 且化学防治对烟田蜘蛛的个体数量影响显著?本文对了解烟田蜘蛛群落生态系统以及烟田的绿色防控奠定理论基础? |

| In order to explore the effects of chemical control on the diversity of spider community on tobacco leaves in tobacco-growing areas in South Anhui, the spiders in the fields with non-chemical control (NCC) (suckercides) and with chemical control (CC) (suckercides and chemical pesticide) were investigated by visual method and flapping-shaking method from April 2021 to July 2021. A total of 1 636 spiders (44 species, 13 families) were recorded and identified, including 943 individuals (40 species, 12 families) in NCC fields and 693 individuals (32 species, 11 families) in CC fields. The oocysts of spiders were attached to the tips and edges of tobacco leaves, and the peak period appeared in late June. According to the temporal dynamics and diversity index of spider community in tobacco fields, the number of spiders in both NCC and CC fields reached the maximum in mid-May, but the richness showed a cetain fluctuation, and the diversity index and evenness index reached the maximum in late-June to early July, but the dominant concentration index was the minimum in this period. Hylphantes graminicola and Ummeliata insecticeps were the dominant species in both fields. By comparing the diversity of spider communities in the two types of fields, the results showed that the spider community in NCC fields was more stable than that in CC fields, indicating that chemical control had a significant impact on the number of spider individuals in tobacco fields. This study provides a theoretical foundation for understanding the community ecosystem and sustainable control of spiders in tobacco fields. |
