This article provides information about the role of entomophages in the fight against Noctuidae and their numbers. As a result of research, calendula officinalis is harmed by Heliothis armigera Hb, Phytometra gamma L, Agrotis segetum Den. et Schiff, Agrotis exclamationis L and Leucania vibellina Hb. Among them, the cotton bollworm is the most common and harmful species. It is known in the pharmaceutical industry as the main raw material used inflorescence of calendula – basket. These pests severely damage not only the roots or stems of plants, but also the most valuable organ – the flower basket. The article discusses the effectiveness of the biological application of the entomophage bracon against the cotton bollworm. When using the entomophage bracon in pest control in the ratio of 1 : 5, the entomophage showed the best efficiency of 78.5-88.2%.
