摘  要:
Six species of wild rice with different ecophenotypes including Oryza grandiglumis (E6-1, E6-3 / 6-4), O. minuta (E13-9, E13-13), O. officinalis (E15-8, E15-13), O. punctata (E16-1, E16-3, E16-13), O. granulata (E7-4), and O. latifolia (101392, E9-1,E9-10) were extracted with methnol and the repellent activity of the extracts against the two insects Aphis citricola and Panonychus citri were studied. The extracts of O. officinalis E15-8 showed higher repellent rate to the two insects than those of the other species. The repellent rates of the extracts of E15-8 to P. citri and A. citricola were 83,26% and 87.86% at 5 x 10~4 pg/mL in 24 h and 87.95% and 82.43% in 48 h, respectively. The extracts of O. officinalis E15-8 had the effect of inhibition tothe esterase of the two insects.
