Em levantamentos realizados durante quatro anos (1977, 1978, 1979 e 1982) estudou-se o parasitismo natural do percevejo verde, Nezara viridula (Linnaeus, 1758) pelo taquinideo Eutrichopodopsis nitens Blanchard, 1966 avaliando-se sua incidencia e a distribuicao dos ovos sobre o corpo do hospedeiro. O indice de parasitismo variou de 27,1% a 52,.7% nos diferentes anos, sendo que coletas de percevejos de janeiro a dezembro de 1982 revelaram que o menor indice de parasistismo ocorreu durante a safra da soja, crescendo a partir de abril e atigindo o maximo no periodo de entressafra. Constatou-se que o grau de parasitismo e o numero medio de ovos por percevejo foi maior nos machos que nas femeas de N. viridula. Quanto ao local de deposicao dos ovos sobre o corpo do hospedeiro, verificou-se ser o torax o de maior preferencia, sendo que o protorax, tanto dorsal como ventralmente, apresentou maior frequencia de ovos. O parasitismo natural de E. nitens em outras especies de percevejos da soja foi insignificante. Constatou-se, entretanto, a presenca dos dipteros Gymnoclytia paulista (Townsend) e Gylindromia brasiliana (Townsend) parasitando adultos de Euschistus heros (Fabricius) e Dichelops sp., respectivamente. |

Tomato (Solanum lycopersicum) is an established model to study fleshy fruit development and ripening. Tomato ripening is regulated independently and cooperatively by ethylene and transcription factors, including nonripening (NOR) and ripening-inhibitor (RIN). Mutations of NOR, RIN, and the ethylene receptor Never-ripe (Nr), which block ethylene perception and inhibit ripening, have proven to be great tools for advancing our understanding of the developmental programs regulating ripening. In this study, we present systems analysis of nor, rin, and Nr at the transcriptomic, proteomic, and metabolomic levels during development and ripening. Metabolic profiling marked shifts in the abundance of metabolites of primary metabolism, which lead to decreases in metabolic activity during ripening. When combined with transcriptomic and proteomic data, several aspects of the regulation of metabolism during ripening were revealed. First, correlations between the expression levels of a transcript and the abundance of its corresponding protein were infrequently observed during early ripening, suggesting that posttranscriptional regulatory mechanisms play an important role in these stages; however, this correlation was much greater in later stages. Second, we observed very strong correlation between ripening-associated transcripts and specific metabolite groups, such as organic acids, sugars, and cell wall-related metabolites, underlining the importance of these metabolic pathways during fruit ripening. These results further revealed multiple ethylene-associated events during tomato ripening, providing new insights into the molecular biology of ethylene-mediated ripening regulatory networks.
