The paper presents data on phytosanitary monitoring of garden cenoses for fire blight in the Turkestan, Zhambyl, and Almaty regions of Kazakhstan. The purpose of this study is to assess the phytosanitary situation in various regions of Kazakhstan, determine the extent of fire blight spread, and isolate and identify the fire blight pathogen. During the study, methods such as hypersensitivity, pathogenicity, and fluorescent simplification-based specific hybridization polymerase chain reaction (FLASH-PCR) were used. It was found that in all the surveyed areas, disease foci were identified. For the first time, the fire blight pathogen was detected on fruit crops such as plum, peach, cherry plum, and quince, as well as on wild apricots. 274 plant samples were collected from which microorganisms were isolated. Isolates related to the fire blight pathogen Erwinia amylovora were identified by methods of hypersensitivity, pathogenicity, and FLASH-PCR diagnostics. Of the 156 isolates of microorganisms isolated from apple tree plant samples, 21 inhibited the in vitro growth of E. amylovora to varying degrees. Isolates 16.2 and 19.2 with maximum antagonistic activity were selected, where the pathogen growth inhibition zones were 52.2 ± 2.58 mm and 45.6 ± 0.55 mm, respectively. Based on the obtained sequence of nucleotides of the 16SpRNA gene site, it was found that the selected isolates with high antagonistic activity belonged to the Pseudomonas genus. In the future, based on these isolates, a new biological product for fire blight control can be created and adapted to the natural and climatic conditions of Kazakhstan.

Climate change is increasingly altering the ecological dynamics of apple orchard ecosystems, creating new challenges for sustainable management of phytophagous mites. Rising temperatures, prolonged drought periods, and increasing climatic variability influence mite population dynamics, destabilize predator–prey interactions, and reduce the effectiveness of traditional pest management approaches. This review examines sustainable mite management in apple orchards through the interconnected perspectives of ecological stability, climatic stress, and resilience-oriented agroecosystem management. Particular attention is given to the ecological mechanisms underlying mite outbreaks, including climate-driven acceleration of reproduction, trophic destabilization, biodiversity loss, and disruption of biological regulation processes. The ecological limitations of both conventional chemical control and biological control strategies are critically analyzed, highlighting issues related to pesticide-induced ecological disturbance, resistance development, climatic sensitivity of natural enemies, and operational constraints. The review further explores resilience-oriented management frameworks based on ecological intensification, habitat diversification, conservation biological control, adaptive management, and system-oriented regulation. Current research gaps are identified, including the lack of long-term ecological studies, insufficient integration of climatic and ecological datasets, limited development of resilience indicators, and underrepresentation of continental and semi-arid orchard systems. The findings suggest that future sustainable mite management should move beyond reactive pest suppression toward ecosystem-based approaches that strengthen ecological resilience and adaptive capacity under increasing climatic uncertainty.

Предпосылка и цель. Интегрированная система защиты малины от вредных организмов занимает важное место в производстве ягодной продукции, так как позволяет обеспечить эффективный контроль численности фитофагов. Одними из доминирующих видов вредителей культуры являются паутинные клещи (Tetranychus urticae Koch) и трипсы (Frankliniella intonsa Trybom.). Повреждение ягод вызывают физиологические нарушения, что приводит к угнетению роста растений и существенному снижению урожайности. Целью исследования является определение биологической эффективности применения хищных клещей Amblyseius montdorensis Schicha и Amblyseius andersoni Chant в регуляции численности паутинного клеща и трипса в насаждениях малины. Материалы и методы. Работы были проведены в 2025 году в питомнике Семиречье (сорт Маричка) и в КХ «Түрген-Жеміс» (сорт Полька) Алматинской области на насаждениях малины. Учет вредителей и определение плотности насекомых проводились по общепринятым методам в энтомологии Результаты. Полученные результаты показали, что наибольшую эффективность против трипсов продемонстрировал Amblyseius andersoni - 83,1%, тогда как биологическая эффективность Amblyseius montdorensis составила 77,9%. В отношении паутинных клещей оба вида хищных клещей показали высокую эффективность: у Amblyseius andersoni она достигала 88,8%, а у Amblyseius montdorensis - 87,8%. Заключение. Проведенные исследования подтвердили высокую биологическую эффективность Amblyseius montdorensis и Amblyseius andersoni против трипсов и паутинных клещей на малине, что подтверждает перспективность их применения в интегрированной системе защиты растений.
