The article elucidates the use of the lacewing (Chrysoprase septempunctata webmail) against the apple red mite (Panonychus ulmi Koch), found in the orchards which are raised in the territory of the republic, at different consumption rates (1: 5, 1: 10, 1: 15), based on its pest ratio and biological effectiveness. The use of the lacewing contributed to 87.8% reduction in the number of apple red mites by the end of the season. Our studies, which were less effective against hemp in the intensive apple orchards on these entomophages, showed that 1 (one) ha of apple trees on the territory of the State Unitary Enterprise of the Kibray district, the Tashkent region, against the harmful red cane (Panonychus ulmi) in Fuji orchards; studies were conducted to determine the biological effectiveness of septempunctured chrysoprase using entomophages.

Мақолада республикамиз ҳудудида интенсив олма мевали боғларда учрайдиган олма қизил канасига (Panonychus ulmi Koch) қарши олтинкўзни (Chrysoprase septempunctata webmail) турли сарф меъёрда (1 : 5, 1 : 10, 1 : 15) қўллаб, унинг зараркунандага нисбати ва биологик самарадорлиги бўйича олиб борилган тадқиқот натижалари ёритилган. Олтинкўз қўлланилганда, мавсум охирига келиб, олма қизил канасининг сони 87,8% гача камайганлиги аниқланган. Бу энтомофаглар бўйича интенсив олма мевали боғларда каналарга қарши тажрибалар самараси камроқ бўлган бизнинг тадқиқотларимиз Тошкент вилояти Қибрай туманида жойлашган Ахборот-маслаҳат маркази (extension center) ДУК ҳудудидаги 1 (бир) гектарлик олманинг Фужи навли боғларидаги зарар келтирадиган олма қизил канасига (Panonychus ulmi) қарши курашда, олтинкўз (chrysoprase septempunctata was) энтомофагини қўллаб, биологик самарадорлигини аниқлаш бўйича тадқиқотлар олиб борилган.
В статье освещено применение златоглазки (Chrysopa septempunctata wesmael) против красного яблоневого клеща (Panonychus ulmi Koch), встречающегося в садах, возделываемых на территории республики, при различных нормах расхода (1 : 5, 1 : 10, 1 : 15), исходя из соотношения вредителей и биологической эффективности. Использование златоглазки способствовало снижению числен-ности красных яблоневых клещей к концу сезона на 87,8%. Исследования, проведенные на 1 га территории интенсивных садов яблони сорта Фуджи ГУП Кибрайского района Ташкентской области, показали, что применение каналов против вредоносного красного плодового клеща (Panonychus ulmi) менее эффективно, чем использование энтомофагов. Также проведены исследования по определению биологической эффективности применения златоглазки (Chrysopa septempunctata wesmael) как энтомофага.
