Abstract

Fluctuation of families of Coleoptera population depending on the application of organic fertilizers

Highlights

The soil edaphon is an important component of biocoenosis, reflects the burden on biotopes and is an important bio-indicator of environmental quality
The experiment was realized during the years 2004–2009, on the locality Kolíňany, by the method of earth traps exposed in the five variants with application of organic fertilizers, as follows: yy1st variant – control; yy2nd variant –25 t ha-1 of the manure application; yy3rd variant – 50 t ha-1 of bio sludge; yy4th variant – 50 t ha-1 of the manure; yy5th variant – 100 t ha-1 of bio sludge
During the six-years period by a method of ground traps, within five variants of collected 60,406 individuals of Coleoptera fauna from a taxonomic point of view pertaining to 16 families, the number of which within individual variations ranged from 12 to 15

Summary

Introduction

The soil edaphon is an important component of biocoenosis, reflects the burden on biotopes and is an important bio-indicator of environmental quality. Presence of Coleopterofauna in natural and artificial biocoenosis plays an important role, which is related to the huge number of species and mainly with their great abundance. Results from studies of epigeic components of individuals with an emphasis on order Coleoptera, according to Schwerk and Dymitryszyn (2015) showed that diversification of biotopes and its environmental characteristics are important in terms of diversity of species. Abundance of order Coleoptera in ecosystems is given by the ration between the soil characteristics, the degree of humidity, altitude and by presence of vegetation. Nietupski et al (2015) states that factors influencing species composition, of almost always dominant family Carabidae, are mainly way of land uses, variability of environmental conditions, environmental moisture and impact of surrounding habitats. For example the moist and shaded biotopes favored species of families Curculionidae, Cantharidae, Nitidulidae (Lengerken and Hanns, 1983). Nietupski et al (2015) states that factors influencing species composition, of almost always dominant family Carabidae, are mainly way of land uses, variability of environmental conditions, environmental moisture and impact of surrounding habitats. Varvara (2010), Gongalsky and Cividanes (2008) considered as critical
