RESEARCH ON THE ENTOMOFAUNA STRUCTURE FROM THE MONOECIOUS HEMP CROP, CULTIVATED IN AN ECOLOGICAL SYSTEM AT A.R.D.S. SECUIENI

Abstract

This work aims to present data related to the structure of the entomofauna and the variation of the relative abundance of species in the ecosystem of the monoecious hemp crop, cultivated in an ecological system. The researches were carried out between 2017 and 2018, in monoecious hemp crop, cultivated in an ecological system, within the Agricultural Research and Development Station Secuieni - Neamț. The biological material was collected by the classic method, namely with the help of Barber-type soil traps, which were installed in the monoecious hemp crop. Later, the collected material was subjected to a mathematical analysis, as a result of which a series of ecological indicators were obtained, highlighting the characteristics of the analyzed biocenosis. 423 specimens were collected, belonging to 4 orders, 11 families, 12 subfamilies, 13 genera and 15 species. The order Coleoptera had the maximum weight by the number of specimens collected (48.70%), while the order Lepidoptera recorded a weight of only 0.24%. The Gryllidae family had the maximum weight by the number of specimens collected (36.88%), while the Noctuidae and Scutelleridae families have 0.24% each.
