Abstract: Adultos de Bonagota cranaodes (Meyrick) (Lepidoptera: Tortricidae) submetidos a tratamentos com água, solu o de mel a 10%, solu o de mel a 10% + 25% de cerveja e sem alimento foram mantidos em gaiolas de PVC transparente para avaliar a fecundidade, longevidade e viabilidade de ovos em laboratório a 25?1degreesC e 70?10% de UR. Maior longevidade de fêmeas e machos e número de ovos/fêmea foram obtidos nos substratos compostos de mel a 10% (17,75 dias, 17,35 dias e 14,07 ovos/postura) e mel a 10% + 25% de cerveja (18,25 dias, 18,20 dias e 12,71 ovos/postura). A viabilidade dos ovos e a dura o do período embrionário foram semelhantes em todos os tratamentos. O substrato alimentar mel a 10% + 25% de cerveja, apresentou efeitos semelhantes ao substrato composto de apenas mel a 10% sobre a longevidade, fertilidade e viabilidade dos ovos. Entretanto, devido ao menor custo, a dieta a base de mel apresenta melhor potencial de utiliza o para manuten o da cria o do inseto em laboratório.

Abstract:

This article brings a discussion about using the Cost Deployment methodology for technological innovation in the World Class Manufacturing (WCM) systems at Fiat Group Automobiles Production System (FAPS). It aims to show how this tool acts in the technical pillars of the WCM, and its proper use as an alternative to innovate in production processes, achieving a drastic reduction in wastes and cost optimization during specific activities in production systems. The Cost Deployment builds a distinctive transversal method of WCM which helps to promote and provide extremely effectiveness in the activation of more specific methods that have been tried successfully in the Japanese manufacturing improvements. It also allows to link the operational performances, usually measured with indicators such as efficiency, providing number of defects, hours of desaturation. The used methodology was based on a literature review about the proposed topic. It ends up finding that the Cost Deployment tool is one of the most sophisticated technological innovations existing for the production systems of the World Class Manufacturing.
