Abstract

调查威尔士中部商业锡特卡云杉人工林中锯蝇(膜翅目,Symphyta)的丰度和多样性
锡特卡云杉在英国是一种广泛种植且具有重要经济意义的树种;因此,识别未来对其生产力的任何生物或非生物威胁都很重要。落叶昆虫被广泛认为是主要的森林干扰因子,其中可能包括锯蝇(Symphyta),众所周知,锯蝇的种群密度很高,会导致重大的疫情爆发,导致树木死亡或影响生长。本研究的目的是调查海拔范围内锡特卡云杉林中锯蝇的丰度和多样性,并评估是否存在任何潜在的重要物种。在威尔士中部的两个商业林场建立了试验区,并使用黄盘诱捕器对成年锯蝇群落进行了为期3年的评估。在这3年的时间里,共捕获了60种锯蝇,占英国已知锯蝇物种的11%以上。结果表明,在海拔较低、温度较高的地区,锯蝇的丰度和多样性普遍较高。在这项研究中捕获的最丰富的锯蝇物种是著名的落叶物种,山地云杉锯蝇(Epicenematus montanus),在哈夫伦森林的低海拔地区发现的数量特别多。实验区还捕获了另外七种与云杉相关的锯蝇。该研究强调了一些与云杉相关的著名锯蝇物种(E.montanus和Pristiphora spp.)的存在,其中一些物种在欧洲造成了云杉(Picea)物种的严重落叶。这些锯蝇在低海拔地区的丰度普遍较高,这表明锡特卡云杉在未来可能更容易受到锯蝇爆发引起的落叶事件的影响,尤其是在考虑到目前预测的气候变化预测时。

期刊介绍: Agricultural and Forest Entomology provides a multi-disciplinary and international forum in which researchers can present their work on all aspects of agricultural and forest entomology to other researchers, policy makers and professionals. The Journal welcomes primary research papers, reviews and short communications on entomological research relevant to the control of insect and other arthropod pests. We invite high quality original research papers on the biology, population dynamics, impact and management of pests of the full range of forest, agricultural and horticultural crops.
