摘要：Essential oils (EOs) extracted from botanical resources have greatly been appraised as insecticides against a broad spectrum of pre-and postharvest pests and pathogens. This study aimed to investigate the chemical constituents of the EO from Rhododendron anthopogonoides and the biological activity of EO and its main com-pound against Tribolium castaneum and Ditylenchus destructor. A total of 14 compounds were identified, and the main components of EO from R. anthopogonoides were 4-phenyl-2-butanone (47.73%), eudesma-3,7(11)-diene (14.52%), curzerene (9.5%), 4-phenylbutan-2-ylacetate (6.43%), beta-cadinene (5.79%), and germacrone (5.73%). The results of bioassays indicated that the EO oil of R. anthopogonoides possessed obvious contact ac-tivity (LD50 = 9.83 mu g/adult) and repellent activity against T. castaneum. The indoor toxicity indicated that the R. anthopogonoides EO and its main constituent 4-phenyl-2-butanone possessed strong nematicidal activity against D. destructor (LC50 = 0.21 and 0.04 mg/mL). These results provided the theoretical basis for controlling T. castaneum and D. destructor using the EO from R. anthopogonoides.
