Resumo do poster apresentado no XXVII ESN International Symposium, Rome, 2004. ; Trichodorid nematodes of the genera Trichodorus and Paratrichodorus are known natural vectors of Tobacco Rattle Virus (TRV) to many agronomically important crops. Previous taxonomic studies have reported several trichodorids, including virus-vector species, from Portugal. The trichodorid group is well defined taxonomically but l...
Some trichodorid species are known to vector specific strains of Tobacco Rattle Virus (TRV) that have a deleterious effect upon several economically important crops, e.g. potato and tobacco. Given the complex relationship that exists between trichodorids and the various TRV strains, it is imperative that a rapid and accurate identification to species level is achieved for the effective use of control measures w...
Em ensaio conduzido em vasos, a céu aberto, estudou-se a reação de Annona squamosa em relação a três nematóides fitoparasitos. As plantas foram inoculadas com 10.000 exemplares de Radopholus similis, Rotylenchulus reniformis ou Meloidogyne exigua por recipiente. Avaliaram-se, após três meses da inoculação, a altura das plantas, o peso fresco do sistema radicular e o número de nematóides nas raízes e no solo. O ...
