Resumo

SPOTTED SPIDE MITE (Tetranychus urticae Koch).The essential oils of the leaves and fruits obtained by hydrodistillation of Xylopia sericea, collected in the restinga area of Pernambuco, were analyzed by GC (HP 5890 SERIES II) and GC/MS (HP 5890B SERIES II/ MSD 5971).A major part of the volatile components identified in the oils of fruits and leaves were monoterpenes and sesquiterpenes.Cubenol (57.43%) and α-epi-muurolol (26.09%) were the main compounds found in the leaves, whereas β-pinene (45.59%) and α-pinene (17.18%) were the fruits major components.The acaricidal activity of the essential oils was evaluated for Tetranychus urticae.The oil of the leaves was more active than that of the fruits showing an LC 50 value of 4.08 μL/L of air for a 72 h period.
