Abstract

This paper summarizes the available data on the host plant associations of beetles of the superfamilies Chrysomeloidea and Curculionoidea on three unique natural objects, relict mountains (shikhans) composed of organogenic limestones and located near Sterlitamak in Bashkortostan. A total of 427 species from 9 families have been recorded on these mountains, this number comprising 35.5% of the total fauna of phytophagous beetles in the foreststeppe of the eastern Russian Plain and the Cis-Urals. In particular, 341 species of phytophagous beetles have been found on Tratau, 281 species on Kushtau, and 276 species on Yuraktau. Trophically specialized beetles (368 species, or 87% of the fauna) were found on 232 plant species from 40 families; of these, 213 monophagous or narrowly oligophagous species were found on 141 plant species from 35 families. Only polyphagous (generalist) herbivores were found on plants of 5 more families. The vast majority (75%) of the oligo- and monophagous beetle species are associated with host plants from 8 families, and half of them (49.7%) are associated with those from 3 families: Asteraceae, Fabaceae, and Brassicaceae. The beetle complexes associated with some plants on the shikhans are described in detail. The consortia of many rare and relict plants include not only common polyphagous beetles but also specialized herbivores (regional monophages or narrow oligophages), some of them living there in isolated parts of their disjunctive ranges or on the periphery of their distribution. The reviewed data indicate high specificity of the biotic complexes of the shikhans, emphasizing the uniqueness of these natural objects and the need for their preservation.

噬食性甲虫（鞘翅目：金线虫，Curculionoidea）与独特Sterlitamak Shikhans上植物的星座关系

摘要

本文总结了在三个独特的自然物体，即由器官形成的石灰岩组成的遗迹山（shikhans），位于巴什科尔托斯坦共和国斯特里塔玛克附近的超家族金龟子和弯孢菌的寄主植物协会的可用数据。在这些山脉上，总共记录了来自9个科的427种，占俄罗斯东部平原和顺乌拉尔森林草原的植物食性甲虫总数的35.5％。特别是，在Tratau发现了341种食植物甲虫，在Kushtau发现了281种，在Yuraktau发现了276种。在40个科的232种植物中发现了营养特化的甲虫（368种，或动物群的87％）。其中，在35个科的141种植物中发现了213种单食性或狭义的少食性物种。在另外5个科的植物上仅发现多食性（类属食草动物）。绝大多数（75％）的寡食和单相甲虫物种与来自8个科的寄主植物有关，其中一半（49.7％）与来自3个科的菊科，菊科，十字花科和十字花科。详细描述了shikhans上与某些植物相关的甲虫复合体。许多稀有和遗迹植物的共同体不仅包括常见的多食性甲虫，还包括特殊的食草动物（区域性单噬细胞或狭窄的寡聚噬菌体），其中一些生活在其分离范围的孤立部分或分布外围。审查的数据表明，shikhans的生物复合物具有很高的特异性，强调了这些天然物体的独特性及其保存的必要性。
