One of the rare ornamental East Asian species whose ecological and biological characteristics make it suitable for landscaping is Alangium platanifolium (Alangiaceae). The natural habitat of this deciduous shrub, located in the southwestern part of the Sikhote-Alin ridge in the Primorsky Territory, is the only one in Russia. To prepare a program for introductory studies and landscaping practice, it is necessary to study the biological and phytocenotic properties, features of development and reproduction of the shrub, and to assess the degree of impact of various negative factors (including pests). Information about phytophagous insects associated with A. platanifolium has been lacking until now. The purpose of the study was to obtain information about the nutrition of Heteroptera on the A. platanifolium growing in the Primorsky Territory. The study was conducted from May to October in 2013, 2024 and 2025 during field trips and at a field station. Visual observation, manual collection of insects, and photography were used. Trophic relationships were studied in the field and in stationary cages for short- and long-term maintenance of insects. Six species of polyphagous bugs belonging to three families (Miridae, Scutelleridae, Pentatomidae) were identified on A. platanophyllum: Neolygus aceris, Poecilocoris lewisi, Palomena viridissima, Eurydema dominulus, Plautia stali, and Lelia decempunctata. At the flowering stage, insects feed on the leaves and flowers; at the fruiting stage and at the end of vegetation, they suck cell sap from the stems, petioles, leaf blades, and fruits. After evaluating the collected data, a conclusion was made about the negative impact of the identified insects on the plant's physiology (disruption of the development of leaf buds, ovary, and fruits). In the case of using A. platanifolium in the landscaping of settlements in the Primorsky Territory, further observations are necessary regarding the diversity and distribution of its phytophages.
