Ushbu maqolada tirnoqgul dorivor о‘simligiga zarar keltiruvchi tunlamlar va ularning sonini boshqarishda entomofaglarning ahamiyati tо‘g‘risida ma’lumotlar keltirilgan. Izlanishlar natijasida dorivor tirnoqgul о‘simligida g‘о‘za tunlami, gamma tunlami, kuzgi tunlam, undov tunlami, leukani tunlamlari uchrashi aniqlangan. Bular orasida g‘о‘za tunlami eng kо‘p uchrashi va zarar keltirishi qayd etilgan. Ma’lumki, farmatsevtika sanoatida tirnoqgul savatchasi asosiy xomashyo sifatida ishlatiladi. Mazkur kemiruvchi hasharotlar nafaqat о‘simlik poyasi, ildizi, guli va shonalari, balki biz uchun kerak bо‘lgan asosiy organi – gul savatchasini ham kuchli zararlab, sifatiga putur yetkazadi. Maqolada g‘o‘za tunlamiga qarshi biologik usulda brakon entomofagini qo‘llash samarasi о‘rganilgan. Brakon entomofagi 1 : 5 entomofag zararkunandaga qo‘llanganda, eng yaxshi 78,5-88,2 samaradorlikka erishildi.

В данной статье приведены сведения о роли энтомофагов в борьбе с совками и их численностью. Исследования показали, что календуле лекарственной наносят вред совка хлопковая, совка-гамма, совка озимая, совка восклицательная и совка люцерновая. Среди них совка хлопковая – самый распространенный и вредоносный вид. Известно, что в фармацевтической промышленности в качестве основного сырья используется соцветие календулы – корзинка. Эти вредители сильно повреждают не только стебли, корни, стебли растений, но и самый ценный орган – цветочную корзинку. В статье рассматривается эффективность биологического применения энтомофага бракон против совки хлопковой. При применении энтомофага бракон в борьбе с вредителями в соотношении 1 : 5 энтомофаг показал наилучшую эффективность – 78,5-88,2%.
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%.
