Отклонения от нормальной эйдономии у жуков-чернотелок (Coleoptera: Tenebrionidae) Центрального и Восточного Предкавказья: естественные травмы

Abstract

A problem of natural traumas among darkling beetles is touched on in this article. Observations of 1473 imagoes of Pimelia capito Kryn., which have one-years phase of imago, have been carried out for this purpose. In natural populations of Pimelia capito Kryn. (environs settlement Peschany, Kursky District, Stavropol Territory) quantity of imago with damages was increasing from 10.00 % in April to 65.76 % in August (approx. 20 % per month); 40.19 % of all investigated beetles was traumatized; 244 kinds of traumas of exoskeleton was registered. Distribution of frequencies of kinds of traumas has been formed by ecological and biological peculiarities of this species of Pimelia capito Kryn. A contact with soil, interspecific and intraspecific competitions in the family Tenebrionidae, unsuccessful contacts with insectivorous vertebrates, activity of human are main traumatic factors for this species of darkling beetles
