Agricultura setor tecnologicamente dominado pelas inovacoes originadas na industria de insumos e equipamentos e pela pesquisa de ponta gerada em laboratorios privados e instituicoes publicas de pesquisa. Na medida em que a analise da dinamica tecnologica incorpora os setores a montante da agricultura, justifica-se o emprego de um quadro concebido para a compreensao de processos que ocorrem na industria. Analisa as trajetorias tecnologicas da industria de equipamentos agricolas, sementes, insumos. Destaque ao progresso tecnico, tanto como elemento da estrategia empresarial, quanto como elemento capaz de definir o padrao tecnologico e a evolucao da industria. |

Feltia subterranea (Fabricius), commonly known as the granulate cutworm, is a common species of owlet moths (Noctuidae) of major agricultural importance, widely distributed in Nearctic and Neotropical regions. This study was conducted to determine the species biological parameters, gather information about its larval host plants, and assess the agricultural significance of this species in the Americas. The viability of the egg, larval, pupal stages, and prepupal period was 98, 98, and 100%, respectively, under laboratory conditions. The average duration of the egg, larval, pupal stages, and prepupal period was 3, 17, 4, and 13 d, respectively. All laboratory-reared larvae developed through five instars. The growth ratio was 1.93 for females and 1.85 for males. The duration of the larval stage was significantly longer in females than in males from the fourth instar. The duration of the pupal stage was significantly shorter in females than in males. When larval and pupal stage durations were combined, there were no significant differences in total development time as a function of sex. In total, 159 botanical taxa belonging to 41 families were recorded as host species for F. subterranea. The families with the greatest number of host species were Fabaceae (22), Poaceae (19), Asteraceae (16), Brassicaceae (13), Solanaceae (12), Amaranthaceae (7), Cucurbitaceae (7), and Malvaceae (5). It is noteworthy that the large number of native weeds used by F. subterranea as host plants could represent a significant source of infestation of crops in the agricultural landscape.
