Deficiências minerais nas fôlhas induzidas por moléstias e pragas

Abstract: Certas moléstias de vírus e o efeito fitotóxico provocado por toxinas de alguns insetos influenciam a composição mineral das fôlhas de plantas afetadas. As alterações provocadas podem se assemelhar a deficiências minerais puramente nutricionais e, em certos casos, há realmente menor teor do elemento associado aos sintomas da moléstia. A aplicação do elemento faltante nos casos citados não provoca geralmente recuperação dos tecidos afetados, com exceção da deficiência de zinco associada à infecção de citros pel… Show more

“…The majority of the data collected are in mostly contrast with those obtained from Acnistus cauliflorus Schott (Solanaceae) and Bougainvillea spectabibs willd (Nyctaginaceae) leaves infested by the two eriophyid mites Aceria acnisti Keifer and Phyllocoptus bougainvilleae Keifer, respectively (Flechtmann and Berti-Filho 1994); also data are agree with those obtained from peanut (Arachis hypogeae L.) leaves infested by the leaf hopper, Empoasca kraemeri Ross& Morre, by Costa(1964) where a significant reduction in N, P, K, Ca, Mg and Mn leaf contents was observed. According to the same author, virus diseases also cause a decrease in the Mg content of cotton and tomato leaves, a decreases in the K content of beet leaves and in the Mn content of orange leaves.…”

“…Sucking insects drain nutrients from their host plants and inject substances which can be toxic to plant tissues and can lead to changes in the mineral content of the plants (Costa, 1964). To verify a possible effect of the feeding of eriophyid mites on the mineral content of the leaves of their host plants, two phytophagous relationships were studied: Aceria acnisti on Acnistus cauliflorus and Phyllocoptes bougainvilleae on Bougainvillea spectabilis.…”
