Abstract

ABSTRACT The diversity and altitudinal distribution patterns of syrphid flies in the Neora Valley National Park, in the Eastern Himalaya was studied, including the ramifications of pollination by drone fly (Eristalis tenax) showing Batesian mimicry of honeybees. Considering the altitudinal variation and visitation rate, the study found a total of 30 Syrphidae species, among which Eristalis himalayensis, E. tenax, Chrysogaster sp., Episyrphus balteatus, Paragus haemorrhous and Syrphus dalhousiae had the highest encounter rate. The maximum number of species was observed at ≥ 2500 m asl. The diversity of Syrphidae in the Neora Valley reflects the supremacy of these flies over other pollinator insects in the study area. The mean visit per hour of drone fly (E. tenax) was 21 ± 2.73SE (SE – standard error) individual at the lower altitudes but the rate was higher (37.1 ± 4.09SE) in the absence of honeybees at the higher altitudes. More information about the primary determinants of the dynamic nature of pollination is required in this area in order to understand plant–pollinator responses to global warming.

印度东喜马拉雅地区传粉昆虫群落中，双翅目蚜蝇沿海拔梯度的分布呈上升趋势

摘要研究了喜马拉雅山脉东部Neora Valley国家公园内同食蝇的多样性和海拔分布模式，包括无人机授粉的后果，无人机（Eristalis tenax）模仿蜜蜂。考虑到海拔变化和造访率，研究共发现了30种水鼠科物种，其中，himalayensis Eristalis、E.tenax、Chrysogaster sp.、Episyrphus balteatus、出血Paragus和达尔豪斯水鼠的造访率最高。在海拔≥2500米处观察到最大物种数量。Neora山谷中Syrphidae的多样性反映了这些苍蝇在研究区域内的优势超过了其他传粉昆虫。在较低海拔地区，无人机（E.tenax）每小时的平均访问量为21±2.73SE（SE–标准误差），但在较高海拔地区没有蜜蜂的情况下，访问率更高（37.1±4.09SE）。为了了解植物-传粉者对全球变暖的反应，该领域需要更多关于授粉动态性质的主要决定因素的信息。

期刊介绍： The aim of Biodiversity is to raise an appreciation and deeper understanding of species, ecosystems and the interconnectedness of the living world and thereby avoid the mismanagement, misuse and destruction of biodiversity. The Journal publishes original research papers, review articles, news items, opinion pieces, experiences from the field and book reviews, as well as running regular feature sections. Articles are written for a broad readership including scientists, educators, policy makers, conservationists, science writers, naturalists and students. Biodiversity aims to provide an international forum on all matters concerning the integrity and wellness of ecosystems, including articles on the impact of climate change, conservation management, agriculture and other human influence on biodiversity.
