- Abstract
This study was conducted with the aim to establish the bioagents of the Chrysopidae (Neuroptera) family feeding on green peach aphid Myzus persicae Sulzer (Hemiptera; Aphididae) in an oriental tobacco crop. The results showed low multiplication density of the aphidophagous species throughout the two-year course of the study. Four representatives of the Chrysopidae were established and the species with the highest densities were seven-spotted lacewing Chrysopa septempunctata Wesmael and beautiful lacewing Chrysopa formosa Brauer -- 55.6% and 27.8%, respectively. Ordinary lacewing Chrysopa carnea Stephens and green lacewing Chrysopa prasina Burmeister related to the control of the green peach aphid represented correspondingly 11.1% and 5.5% of the total number of lacewings, but single representatives were found and hence it could be assumed that they did not play a significant role in the limitation of M. persicae. Later emergence of the lacewings in the tobacco crop was observed, in the period 20th - 30th June of 2021 and 2022, which is a period of relatively high multiplication rate of the green peach aphid.
