Abstract

Nesting of a Brachyodynerus zhelochovtzevi (Kostylev, 1929) female was observed with timekeeping of its activity. The nest was located in the vertical wall of a crack in sandy-loam soil, in a flat spot with halophytic vegetation. The nest entrance was situated at a depth of about 1 cm from the soil surface and was a simple round opening, without an entrance turret. The nest tunnel was about 3 cm long and inclined downwards at about 45°. During the sealing of the cells and the whole nest, the female left the soil crack only to collect liquid for softening the soil; it obtained the liquid from succulent leaves of a plant of the genus Suaeda Forssk. ex J.F. Gmel. (Chenopodiaceae). The completed and sealed nest contained three brood cells, arranged in a row and sealed with soil partitions, and an empty vestibule sealed with a thicker final plug. The egg was attached with a thread to the lateral wall of the cell at its distal end. The female wasp hunted larvae of a single casebearer moth species of the genus Aporiptura Falkovitsh, 1972 (Coleophoridae), feeding on another species of Suaeda; 10–18 such larvae were stored in each brood cell. Adult wasps fed on nectar on the flowers of Limonium otolepis (Schrenk) Kuntze (Plumbaginaceae), Tamarix ramosissima Ledeb. (Tamaricaceae), and Lepidium obtusum Basiner (Brassicaceae). The biology of B. zhelochovtzevi is discussed and compared with that of B. magnificus (Morawitz, 1867) and members of other ground-nesting genera of Eumeninae.

乌兹别克斯坦独居黄蜂 Brachyodynerus zhelochovtzevi (Kostylev, 1929) (Hymenoptera, Vespidae: Eumeninae) 的巢穴记录

摘要观察了一只雌性Brachyodynerus zhelochovtzevi（Kostylev，1929年）的筑巢情况，并对其活动进行了计时。巢位于沙质壤土裂缝的垂直壁上，地势平坦，周围生长着盐生植被。巢穴入口距离土壤表面约 1 厘米深，是一个简单的圆形开口，没有入口炮塔。巢道长约 3 厘米，向下倾斜约 45°。在封闭巢室和整个巢穴的过程中，雌鸟离开土壤裂缝只是为了收集液体来软化土壤；它从一种 Suaeda Forssk. ex J.F. Gmel. 属植物（Chenopodiaceae）的多汁叶片中获取液体。(Chenopodiaceae）。完成并密封的巢穴包括三个育雏室，它们排成一排，用泥土隔开密封，还有一个空的前庭，最后用一个较厚的塞子密封。卵的远端用线固定在育雏室的侧壁上。雌蜂捕食 Aporiptura Falkovitsh, 1972（Coleophoridae）属的一种鞘蛾幼虫，以另一种 Suaeda 为食；每个育雏室存放 10-18 只这样的幼虫。成蜂取食 Limonium otolepis (Schrenk) Kuntze（Plumbaginaceae）、Tamarix ramosissima Ledeb.(柽柳科）和 Lepidium obtusum Basiner（十字花科）的花上采蜜。讨论了 B. zhelochovtzevi 的生物学特性，并将其与 B. magnificus（Morawitz，1867 年）以及 Eumeninae 的其他地栖属进行了比较。
