Essential oils from leaves and fruits of Protium heptaphyllum 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 a-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 Fl.l -1 air), but only the essential oil from fruits induced repellence on T. urticae.

O constituinte majoritário identificado nos frutos foi a-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 %)

“…This class of metabolites covers a wide range of substances of vegetable origin and their ecological importance as defensive is well established. Several monoterpenes were isolated and evaluated for toxicity against different insects and arthropods (VIEGAS JUNIOR, 2003). Our results demonstrate the potential acaricidal activity of A. cearensis, which contributes to the conservation and proper management of this species, since, beyond economic potential; they are likely to be exploited as sources of new biologically active substances.…”

RESUMOO desenvolvimento da humanidade nos últimos tempos tem mudado o ambiente natural ao quais todos se inserem. Estas mudanças, em sua grande parte, são impactos sobre a fauna e a flora. Além das indústrias e da cidade, a agricultura também interfere nesta mudança, vê-se o crescimento intensivo e uso indiscriminados de agrotóxicos, do solo, da água, além dos desmatamentos e uso intensivo e prolongado de monoculturas -em que todos estes fatores prejudicam o meio ambiente, incluindo o próprio homem. Entretanto a tecnologia busca alternativa e mecanismos para auxiliar o desenvolvimento agrário sem prejudicar o ambiente, isto é o que propõe as leis e conferências para o desenvolvimento sustentável. Um exemplo é o uso de substâncias naturais para prevenir pragas em substituição dos agroquímicos que causam danos. A água, por exemplo, pode ser usada de uma forma mais racional com uso de irrigação ou fertirrigação por gotejamento, onde já foi comprovado uma grande economia de água e o desenvolvimento melhor das plantas em questão. Portanto este trabalho teve o objetivo de mostrar o papel da agricultura na decadência da sustentabilidade, mas também rever as tecnologias e alternativas existentes para que haja um desenvolvimento conjunto do ambiente e da agricultura. Palavras-chave: impacto ambiental, alternativas, agricultura orgânica, meio ambiente ABSTRACTThe development of humanity in recent times has changed the natural environment. These changes, for the most part, are impacts on fauna and flora. In addition to the industries and the city, these changes also have been affected by agriculture, there are the intensive growth and indiscriminate use of pesticides, of soil, of water, and of deforestation and intensive and prolonged monoculture -all these factors affect the environment, including man himself. However there are researches about alternative technology and ways to assist agricultural development without harming the environment, this is what the laws and conferences propose for sustainable development. An example is the use of natural substances to prevent pests, rather than agricultural chemicals. Water, for example, can be used with more rational or by drip irrigation, that shows a great saving of water and better development of the plants. Therefore this study aimed to show the role of agriculture in the decadence of sustainability, but also reviews the
