Abstract
The work provides data on the dynamics of the abundance of 205 taxa from 19 genera: Cleptes, Colpopyga, Elampus, Omalus, Philoctetes, Pseudomalus, Hedychridium, Hedychrum, Holopyga, Chrysidea, Chrysis, Euchroeus, Chrysura, Pseudochrysis, Spinolia, Spinolia, including species rare and new for the fauna of the North Caucasus and Russia. By the nature of the population dynamics, five groups of cuckoo wasps were identified: spring – represented by 7 species from 4 genera; spring-summer – 76 species from 10 genera; summer – 113 species from 16 genera; summer-autumn – 4 species from 2 genera and spring-summer-autumn – 5 species from 3 genus. According to the duration of flight, eurychronous species of cuckoo wasps were identified, which are found throughout the season from spring to autumn; mesochronous – the years of which affect the end of May and summer months and stenochronous – confined to a short period of time. Eurychronic accounted for 2.4%, mesochronous 24.9%, stenochronic 72.7%. The number of generations of cuckoo wasps is related to the dynamics of the number of the host. In the mountains, the peaks of activity shift towards the middle of summer, most species have one peak of activity; due to the frequent changes in weather conditions in the mountains, the phenological characteristics of the cuckoo wasps and their hosts do not coincide in terms with the lowland populations and the periods of activity can be extended in time. Phenological characteristics of rare and new species for the fauna of the North Caucasus and Russia are presented for the first time. The data obtained expand the understanding of the biodiversity and dynamics of the abundance of cuckoo wasps in the North Caucasus and can be used for environmental protection measures and rational nature management in the south of Russia.
Highlights
Cuckoo wasps (Chrysididae: Cleptinae, Chrysidinae) is a widespread group of hymenoptera; in the fauna of Russia there are 340 species and 13 subspecies from 23 genera [1]
As shown by the research results, 205 taxa from 19 genera were recorded in the dynamics of the abundance of cuckoo wasps in the Northern Caucasus: Cleptes, Colpopyga, Elampus, Omalus, Philoctetes, Pseudomalus, Hedychridium, Hedychrum, Holopyga, Chrysidea, Chrysis, Euchroeus, Chrysura Spintarina, Stilbum, Trichrysis, Parnopes
The cuckoo wasp C. frivaldzkyi sparsepunctata was recorded for the first time in the North Caucasus, it is rare, and additional information on the dynamics of numbers can clarify its phenological characteristics
Summary
Cuckoo wasps (Chrysididae: Cleptinae, Chrysidinae) is a widespread group of hymenoptera; in the fauna of Russia there are 340 species and 13 subspecies from 23 genera [1]. Data on the dynamics of the abundance of wasp wasps in mountainous and foothill landscapes North Caucasus are presented. It is known that mountain landscapes have their own characteristics, where the parameters of the biota naturally change in all three dimensions of space, depending on the biological effect. Taking into account the current state of the of the interaction of mountains and adjacent plains, factors of zoning in the plain and zonality in the mountains [5], taking into account the current state of the recreational load on the natural landscapes of the North Caucasus, and the expansion of monitoring studies, knowledge of the patterns of the dynamics of the abundance of components of biocenoses is important
