Identification of Oviposition, Development, and Overwintering Induction Conditions of the Anoplophora malasiaca under Laboratory Rearing Conditions
Abstract
Over the past three years, the citrus longhorned beetle (Anoplophora malasiaca = A. chinensis) has caused significant infestations, beginning in citrus orchards on Jeju Island in 2020 and later spreading to blueberry farms by 2023. To establish biological control strategies, this study investigated the basic ecology and artificial propagation methods of A. malasiaca. In a blueberry greenhouse in Cheonan, Chungcheongnam-do, mass occurrences were observed in June, with males collected more frequently than females. Oviposition was mainly observed at the basal part of host trees. Under artificial rearing conditions, larvae reared at 26°C followed by 30 days of cold exposure at 10°C for diapause induction exhibited developmental durations of 207–243 days as larvae, 14–15 days as pupae, and 37–64 days as adults, resulting in a total life cycle of 263–338 days. Larval pupation was further promoted by 30 days of overwintering stimulation at 5°C. Adults oviposited between the bark and woody tissues at the junction of the substrate and lower branches, with the highest number of eggs laid on blueberry branches approximately 2 cm in diameter near the basal part. Among different host species, oviposition was greatest on willow branches supplied with fresh shoots. These findings clarify the optimal conditions for oviposition, larval development, and diapause induction of A. malasiaca, providing fundamental information for developing biological control strategies and improving artificial rearing efficiency.
