O desenvolvimento rural entendido como a somatória de conquistas não apenas no campo econômico, mas também social, político, ambiental e cultural, tem-se constituído preocupação constante dos órgãos de pesquisa e extensão, ONGs e poder público, comprometidos com a melhoria das condições de vida da população do campo. Por outro lado, estas instituições têm sido constantemente criticadas pela ineficácia dos projetos implementados neste sendido. Uma das críticas mais contundentes diz respeito às metodologias que ignoram o protagonismo dos agricultores nos programas de pesquisa e desenvolvimento. O texto a seguir discute a viabilidade de se adotar abordagens qualitativas a na pesquisa em agricultura familiar, explicitando as vantagens deste paradigma para o estudo deste cmplexo sistema agrário. Embora crescente, o número de pesquisadores que utilizam referenciais qualitativos ainda é insuficiente para responder a demanda desta população, historicamente marginalizada nos processos de desenvolvimento. Neste cenário, o texto busca demarcar as diferenças entre paradigmas quantitativo e qualitativo e, ao mesmo tempo, ressaltar a importância de se buscar a complementaridade entre ambos, de forma a garantir maior eficácia nas pesquisas em agricultura familiar. |

Efficient management of whitefly-borne diseases remains a challenge due to the lack of a comprehensive understanding of their epidemiology, particularly of the diseases tomato golden mosaic and tomato yellowing. Here, by monitoring 16 plots in four commercial fields, the temporal and spatial distribution of these two diseases were studied in tomato fields in Brazil. In the experimental plots these diseases were caused by tomato severe rugose virus (ToSRV) and tomato chlorosis virus (ToCV), respectively. The incidence of each virus was similar in the plots within a field but varied greatly among fields. Plants with symptoms for both diseases were randomly distributed in three of four spatial analyses. The curves representing the progress of both diseases were similar and contained small fluctuations, indicating that the spread of both viruses was similar under field conditions. In transmission experiments of ToSRV and ToCV by Bemisia tabaci MEAM1 (former biotype B), these viruses had a similar transmission rate in single or mixed infections. It was then shown that primary and secondary spread of ToCV were not efficiently controlled by insecticide applications. Finally, in a typical monomolecular model of disease pro- gress, simulation of the primary dissemination of ToSRV and ToCV showed that infected plants were predominantly ran-domly distributed. It is concluded that, although the manner of vector transmission differs between ToSRV (persistent) and ToCV (semipersistent), the main dispersal mechanisms are most probably similar for these two diseases: primary spread is the predominant mechanism, and epidemics of these diseases have been caused by several influxes of viruliferous whiteflies.
