摘要
【目的】探明辽宁宽甸黄椅山森林公园寄蝇的种类及其动态规律,筛选出反映森林状况和动态的指示性昆虫。【方法】2017-2018年5-9月采用网捕法监测了黄椅山森林公园的寄蝇种群,并分析了寄蝇群落的种-多度曲线、多样性指数、个体数、物种丰富度、均匀度与多样性的关系。【结果】黄椅山森林公园寄蝇已知4亚科23族162种,以追寄蝇亚科的种类为多。寄蝇群落的种-多度关系符合生态位优先占领模型,多样性指数与均匀度不相一致,而与物种丰富度一致。【结论】黄椅山森林公园寄蝇种类丰富,其中寄蝇常见种和优势种种类极少,而少见种种类集中,即黄椅山森林公园寄蝇赖以生存的生态环境不稳定。筛选出怒寄蝇Tachina(s.str.)nupta(Rondani)作为指示性昆虫监测森林的生态环境状况;提出了合理保护和利用森林资源的建议。
[Objectives]To clarify the diversity and occurrence patterns of members of the Tachinidae in Mt.Huangyi Forest Park,Kuandian,Liaoning,China,and identify species that are indicators of forest status and population dynamics.[Methods]The Tachinidae population in Mt.Huangyi Forest Park was monitored using the net trap method from May to September 2017 and 2018.The species-abundance curve,diversity index,number of individuals,species richness,and the relationship between evenness and diversity,were analyzed.[Results]162 known species in 4 subfamilies,most of which were in the Exoristinae,were identified.Species abundance relationship supported the niche preemption model.The diversity index was consistent with species richness,but not with evenness.[Conclusion]Although there are many tachinid species in Mt.Huangyi Forest Park,there are very few common and dominant species,and rare species are localized.This indicates that the Tachinidae community of Mt.Huangyi Forest Park is not stable.Tachina(s.str.)nupta(Rondani)was identified as an indicator species for monitoring the ecological health of forests.Some suggestions for the rational utilization and protection of the forest are proposed.
