“…«Вестник НГАУ» -4 (69)/2023 ВЕТЕРИНАРИЯ И ЗООТЕХНИЯ Биоразнообразие насекомых находится под угрозой его обеднения во всем мире. Обзор работ, свидетельствующих о сокращении численности различных видов насекомых, показывает резкие темпы ускорения этого процесса, которые могут привести к исчезновению 40% видов насекомых в мире в течение следующих нескольких десятилетий [1]. Основными причинами этого являются: потеря среды обитания и переход к интенсивному сельскому хозяйству и урбанизации; загрязнение, в основном синтетическими пестицидами и удобрениями; биологические факторы, включая патогенные микроорганизмы и интродуцированные виды; изменение климата [2].…”

It is generally recognised that pesticides play a significant role in the decline in the number of insects observed worldwide. The analysis of the causes of unprecedented losses of Apis mellifera L. bee colonies has been carried out. When using plant protection products in agrocenoses. The current state of knowledge on assessing the impact of pesticides on non–target objects is summarised as honey bees and other types of bee pollinators of plants. The mechanisms and features of selective exposure of insecticides from the group of neonicotinoids, butenolides and based on fipronil are described. In addition to direct lethal effects, there is a decrease in the viability and subsequent death of bee colonies as a result of changes in the cognitive abilities of worker bees, the reproductive potential of queens and drones, changes in the immune status of bee colonies and the etiological characteristics of insects. Examples of the negative impact on honeybee populations of various regions of the Russian Federation when using pesticides in agrocenoses are given. The role of organic agriculture in the conservation of honey bees and other pollinators, providing a yield comparable to the integrated plant protection system of entomophilic crops, is noted. Measures to prevent the reduction of honey bee populations due to pesticide toxicosis are outlined: 1. Compliance with the requirements of regulatory documents; 2. Providing apiaries with an optimal feed base; 3. Exclusion of highly toxic insecticides from entomophilic crop protection programs; 4. Realisation of the adaptive potential of honey bees in changing environmental conditions; 5. Transition to organic farming in the cultivation of entomophilic crops.

The wild bee community of a sand steppe habitat in Eastern Austria was surveyed in the years 2018 and 2019, complemented with historical data from over 100 years, and analyzed in relation to land use change. The mapping of land use categories was based on historical aerial photographs and orthophotos. Changes in bee community composition were analyzed by a multivariate statistical approach and took ecological traits into account (lecty, nesting type, habitat requirements, flight period, parasitism). In total, 310 bee species were recorded in the area, with the oldest records dating back to 1882. The bee species composition differed significantly among four defined time periods. Across the two most intensively sampled time periods (1931–1966 vs 2001–2021), a decline in species richness of over 50% was observed. We observed a disproportionally high decline of steppe- and sand-associated species, and a distinct shift from ground nesting species to above-ground nesting species. The area covered with woods increased from 1966 to 2018, while the total area covered with grassland and fallows decreased slightly between 1966 and 1994. The oligolectic species assemblage was specialized on Dipsacaceae, Brassicaceae and Fabaceae in the two earlier periods, and on Asteraceae and specifically on Carduoideae during the two later ones. Implications for insect conservation stronger reference to historic land management practices as short time periods of intensive grazing and small-scaled, staggered mowing would be desirable to improve the habitat quality. More drastic measures, such as removal of the topsoil in some parts and changes in the landscape re-establishing exposure to wind erosion, might be necessary, if the area is to be fully restored to the condition it was in a century ago.
