Abstract
Essential oils from leaves and fruits of Protiumheptaphyllum collected in Tamandaré beach Pernambuco/Brazil were analysed by GC/MS and tested for toxicity and repellent effect against the two spotted spider mite (Tetranychus urticae). The major constituent identified in the fruits was alpha-terpinene (47.6 %) whereas oil from leaf contained mainly sesquiterpenes such as 9-epi-caryophyllene (21.4 %), trans-isolongifolanone (10.7 %) and 14-hydroxi-9-epi-caryophyllene (16.7 %). The fruit oil was found to be more effective against the mite when compared to the leaf oil. Both showed mortality properties and oviposition deterrence in higher concentration (10 µl.l-1 air), but only the essential oil from fruits induced repellence on T. urticae.
O óleo essencial das folhas e frutos de Protiumheptaphyllum coletada em Tamandaré-Pernambuco foi analisado por CG/EM e testado sua toxicidade e efeito repelente contra ácaro rajado (Tetranychus urticae). O constituinte majoritário identificado nos frutos foi alfa-terpineno (47,6 %) enquanto que nas folhas foram os sesquiterpenos 9-epi-cariofileno (21,4 %), trans-isolongifolanona (10,7 %) and 14-hidroxi-9-epi-cariofileno (16,7 %). O óleo dos frutos foi mais eficiente contra o ácaro, comparado com o óleo das folhas. Ambos os óleos revelaram propriedades de mortalidade e deterrência de oviposição na maior concentração (10 µl.l-1 air) e apenas o óleo essencial dos frutos induziu repelência no T. urticae.
