Influence of Heavy Metals and Radiation on Biodiversity of Coccinellidae

摘要

It has been revealed the influence of heavy metals and radiation on biodiversity of coccinellids. It has been determined that the greatest concentration Fe, K and activity of U~(238) and K~(40) isotpes in the organism of coccinellids Coccinella 5 quinquepunctata and Thea 22-punctata, which is an indicator of appearance of brightness of color. Higher concentration of metals and activity of U~(238) and K~(40) isotpes has been defined in the organisms of coccinellids Coccinella 5 quinquepunctata and Thea 22-punctata are the brightest reflection of pollutants' influence appear the given one, that can be used for features of pollution degree of particular area. Therefore, this kind of coccinellids - Coccinella 5 quinquepunctata and Thea 22-punctata can be criteria in the capacity of bioindicator of environment.
