摘要
[目的]明确南京市主要植被群系毒蛾科昆虫群落结构及其多样性,以更好地保护南京市森林生态及植树造林成果.[方法]研究了南京市主要植被群系植物种类及毒蛾科昆虫种类、种群密度、分布及发生规律,并进行了多样性分析.[结果]南京市5种主要植被群系共有毒蛾科昆虫15属32种,优势种为枫毒蛾、条毒蛾、绿点足毒蛾、鹅点足毒蛾、华竹毒蛾;昆虫本身的生物学特征、气候条件、生态环境是影响蛾类群落结构及动态的主要因素;毒蛾科昆虫种群动态有明显的时序变化,这种变化在很大程度上与季节性的温度变化有关.[结论]研究结果为有害生物的预测预报和防治提供了理论依据.
Abstract
[Objective] The aim was to study the community structure and diversity of insects of Lymantriidae in main vegetation formation in Nanjing City,so as to better protect forest eco-system and afforestation achievements in Nanjing.[Method] The plant species and insect species of Lymantriidae,population density,distribution and occurrence regularity in the main vegetation formation of Nanjing were investigated and analyzed by the diversity analysis method.[Result] The results showed that there were 15 genera,32 species of insects of Lymantriidae in the five kinds of main plant formation of Nanjing;Lymantria umbrifera (Wileman),Lymantria dissoluta (Swinhoe),Redoa leucoscela Collenette,Redoa anser Collenette,Pantana sinica Moore were dominant species.Insect biology characteristics,climatic conditions,the ecological environment were the major factors that impacted the community structure and dynamic of the moth.Insect population dynamics of Lymantriidae had obvious temporal changes,the change was largely related to the seasonal temperature changes.[Conclusion] The study results can provide theoretical basis for forecasting and prevention of harmful organisms.
