Compostos orgânicos voláteis na defesa induzida das plantas contra insetos herbívoros

Abstract: Recebido em 5/2/13; aceito em 4/7/13; publicado na web em 9/8/13 VOLATILE ORGANIC COMPOUNDS IN INDUCED PLANT DEFENSE AGAINST HERBIVOROUS INSECTS. The identification and manipulation of chemical compounds involved in vital activities of arthropods have the potential for developing less aggressive pest control strategies. Herbivory induces the emission of volatile organic compounds involved in the recruitment of natural enemies, plantplant interactions and repellency of other herbivores. In this report, we revie… Show more

“…MeSA is an important signaling compound of systemic acquired resistance (SAR) in plants, 27 and is involved in the response against herbivory in different plant cultures. 7,28 For example, it attracted different families of beneficial insects in open field and hop yards (e.g. Syrphidae, Braconidae, Empididae, Sarcophagidae), 28,29 and affected the abundance of organisms of different trophic levels in studies with Brassica rapa (Brassicaceae).…”

“…The absence of qualitative differences against MD and herbivory treatments was in a certain way expected as phytophagous insects that cause extensive feeding damage on plant tissues induce changes in gene expression and accumulation of secondary metabolites similar to mechanical wounding. 32 However, elicitors are usually present in the oral secretion of lepidopteran larvae inducing defense responses in plants 7 and might be responsible for the quantitative differences between HB and MD treated plants. This quantitative distinction is likely to affect the perception of enemies of these herbivores, as it is also suggested by the two different patterns of emission in both herbivories (A in TC and B in HB, Figure 3).…”

“…A descoberta e o intenso estudo em nível bioquímico das defesas induzidas (diretas e indiretas) estão formando uma nova geração de pesquisas para promover as respostas das plantas ao ataque de insetos herbívoros. 25 Dentro das defesas induzidas destaca-se um mecanismo referido como priming (preparação), pelo qual a planta adquire a habilidade para responder melhor a futuros ataques dos herbívoros, após a aplicação exógena de indutores químicos. Durante os últimos anos foram identificadas muitas substâncias naturais e análogos sintéticos que induzem e favorecem as defesas quí-micas da planta, que estão sendo avaliadas para o controle de pragas e doenças.…”
