This study provides original data on the association of the weevil Fald. (Coleoptera, Curculionidae) with the Manchurian saw-wort Kitag. (Asteraceae) in natural habitats in southern Primorskii Territory (Russian Far East). In the biotopes under study, showed selectivity towards over other plants of the family Asteraceae, . Imagines were collected from inflorescences and infructescences of this plant until late August and early September and from inside infructescences, from the early 3rd ten days of August to late September. Larvae pupated in pupal chambers inside from early August and were found until early September. The duration of pupal development was 13 days; complete sclerotization of cuticle occurred approximately 24 h later. The emergence of a new generation of adults from the Manchurian saw-wort was observed from the early 1st third to the late 2nd third of September.
