Abstract: Resumo: o presente trabalho teve por objetivo fazer uma triagem das substâncias, das mais diversas origens, sem necessariamente ter um efeito inseticida que aplicadas nas plantas doentes fontes de vírus (aquisição) ou nas plantas sadias receptoras de vírus (inoculação), fossem capazes de interferir na transmissão de vírus por inseto vetor, alterando sua capacidade vetora com consequente redução da infecção viral. Na escolha das substâncias deu-se ênfase especial aos resíduos e subprodutos agrícolas e industriais, extratos vegetais, óleos e outras. O valor interferente das substâncias foi avaliado nas fases de aquisição e inoculação dos vírus separadamente

Abstract: An array of substances from varied sources, mostly without known insecticide action, were screened as to their interfering value in the transmission of plant viruses by their aphid or whitefly vector. When selecting substances for trials, preference was given to agricultural and industrial residues or by-products, plant extracts, vegetable and mineral oils, and others. Most of the tests were carried out in the greenhouse by applying the substance to be evaluated on the leaves of the virus donor plants prior to confining the non-viruliferous vector of them for acquisition and further testing on healthy untreated test plants; or were applied on leaves of healthy receptor test plants before caging on them viruliferous vectors that had acquired virus from untreated donor plants. In some field exposure tests, the substances were tried as interferers to vector inoculation only
