RESEARCH ON THE BIODIVERSITY OF CARABIDS (ORDER Coleoptera, FAMILY Carabidae), PREDATORY INSECTS IN SOME AGRICULTURAL ECOSYSTEMS ACCORDING TO THE APPLIED TECHNOLOGY AND IN THE CONTEXT OF NEW CLIMATE CHANGES

Research was done during 2023 on three field crops: wheat, corn and sunflower. The collection of the material was done with the soil traps Barber type, and the collection of biological material was made every two weeks, starting from May to September depending on the culture. We were organized two variants in the experimental stationary, depending on the technologies (treatment scheme applied) to each culture as follows: V1, the field where no chemical treatment was done (ecological variant); V2, the field to which chemical treatments were applied, if necessary to the seeds and during the vegetation period (conventional variant). From the material collected from the Barber soil traps during to the five months, were selected only the carabid species that were then identified. Regarding the analysis and interpretation of the results, two indices of the diversity of the species were also calculated, namely: the Sorensen index and the Spearman index whose values show how similar the cultures compared to each other are, two by two.
