title: Chemical composition and insecticidal activity of essential oils from Vanillosmopsis pohlii baker against Bemisia argentifolii.
abstract: Essential oils from the heartwood and leaves of specimens of Vanillosmopsis pohlii collected in two different localities were analyzed by GC-MS. The major constituent of both heartwood essential oils was the sesquiterpene alpha-bisabolol. Essential oil composition from leaves was quite different for two specimens and showed beta-pinene and E-caryophyllene as principal constituents. The essential oil of heartwood and the pure sesquiterpene alpha-bisabolol were tested against Bemisia argentifolii, the white fly fruit plague, and pronounced insecticidal effects were observed.
