CONTRIBUTIONS TO THE STUDY OF THE COMPOSITION AND DYNAMICS OF THE ARTHROPOD FAUNA FROM SOME CORN CROPS IN THE N-E REGION OF MOLDOVA

Abstract

In order to maintain biodiversity on intensively exploited agricultural land, the monitoring of harmful and useful species is extremely important, as it provides information on the quality of the land and, why not, can provide predictions on the stability of agroecosystems.

The observations regarding the structure of the arthropod entomofauna were made between April and July in the year 2021 in a corn crop in the town of Ghigoiesti. The research carried out aimed to determine the structure and composition of the entomofauna, its abundance and diversity as well as their behavior in the maize crops in the station under observation, and the research was based on the use of Barber-type soil traps, a total of 6, placed in 3 in a row, which have as fixing solution a salt solution (NaCl) with a concentration of 20% for each of the three variants studied. The collected material is represented by species belonging to the arthropod fauna that systematically fall into the following orders: Coleoptera, Hymenoptera, Orthoptera, Diptera, Arachnida s.a.
