The data on the collection of Orthoptera (Insecta: Orthoptera) for 2024–2025 in various biotopes from two protected areas of the Saratov region – Khvalynsky National Park and Nizhne-Bannovsky Natural Monument, as well as from adjacent territories, are presented. A list of 44 species of insects from 3 families is presented, potential pests of agricultural crops found in the studied territories are indicated, as well as species listed in the Red Book of the Saratov region.

 The article reports on the discovery of Keller’s broomrape (Orobanche kelleri Novopokr., Orobanchaceae) in the Saratov region, a species with a fairly extensive range but extremely sporadic occurrence. Information on the distribution of the species in Europe and Central Asia is provided. The nearest known occurrences of this species are from the Rostov and Volgograd regions. O.

Eggplant, or dark-fruited nightshade (Solanum melongena L., 1753), is an important agricultural crop, for which the use of biopreparations based on antagonist microorganisms is advisable. The success of introducing such strains into an agrocenosis is largely determined by their interaction with the host plant’s autochthonous microbial community, which can vary significantly across regions. This study analyzed the microbiota structure of eggplant plants grown in the Saratov region. One hundred healthy leaf samples were microbiologically analyzed.

Soil and climatic conditions are factors influencing the composition and structure of microbial communities of various agrocenoses. Since microbiota plays a key role in the development of plant resistance to pathogens, studying its regional dynamics is of signifi cant scientific and practical interest. A comparative study of the microbiota of eggplant (Solanum melongena L., 1753) plants grown in diff erent soil and climatic conditions in the right- and left-bank areas of the Saratov Region was conducted. One hundred healthy leaf samples were microbiologically analyzed.

For 11 years, the staff of the Scientifi c Research Center “Botanical Garden” of SSU named after N.G. Chernyshevsky have been reintroducing a rare protected plant, Calophaca wolgarica (L. fi l.) DC., into potentially suitable places in the Saratov Region. This species is considered extinct in the region. Restoration of the species in the Saratov Region will expand its range, increase the biodiversity of the local fl ora and enrich biogeocenoses. Seed material for the reintroduction of C. wolgarica was collected from natural cenopopulations in the Volgograd Region.

Concerning the distribution of Allium caeruleum Pall. and A. regelianum A. K. Becker, recent literary sources provide confl icting information. Based on the data from the doctoral dissertation of A. O. Tarasov, the results of expeditionary research and our own herbarium collections, it is stated that Allium caeruleum is distributed in the Ozinsky (at least in the vicinity of the village of Nepryakin) and in the Aleksandrovo-Gaisky (at least in the vicinity of the village of Kamyshki) districts of the Saratov region. The presence of A.
