Las semillas de cuatro tipos forasteros de cacao fueron asignadas a seis grupos en funcion de su gravedad especifica (g.e.) utilizando um sistema agua-azucar (sacarosa). Tales grupos fueron g.e. menor de 1.00; de 1.00 a 1.03; de 1.03 a 1.06; de 1.06 a 1.09; de 1.09 a 1.12; y superior a 1.12. Las semillas de cada grupo fueron estudiadas en relacion a su influencia sobre la germinacion, desarrollo del tallo y la raiz, produccion foliar, y peso fresco y peso seco de tallos y raices. Se tomo nota de las variaciones entre los tipos respecto a la distribucion de semillas por cada grupo de gravedad especifica, asi como por su influencia een las caracteristicas de las plantulas. Asi, un incremento en gravedad especifica fue altamente correlacionado com un incremento en desarrollo y en produccion de materia seca. Debido a esta relacion, el metodo puede ser utilizado en la seleccion masal de semillas de cacao para mejor desarrollo de las plantulas y posiblemente tamien para una mayor habilidad en llegarse a establecer. La seleccion a favor de semillas de elevada gravedad especifica asegurara una mayor uniformidad de plantulas vigorosas y puede resultar beneficiosa en promover una mayor habilidad en llegarse a estabelecer asi como tolerancia a la sequia durante el periodo critico inicial de crecimiento. |

The weevil Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae: Bruchinae) is a cosmopolitan pest that causes high losses in stored beans in small storage units and especially on-farm storages. Here, it was tested the efficacy of the inert dust diatomaceous earth (DE) as an alternative to control A. obtectus in common beans (i.e., Phaseolus vulgaris L.) on different storage temperatures and exposure intervals. Using a Completely Randomized design four doses (0.25, 0.50, 0.75 and 1.00g kg-1) of diatomaceous earth on beans kept at different temperatures (25, 28, 30, 32 and 35°C). Insect mortality was evaluated after two or five days of exposure. The impacts of diatomaceous earth in the offspring of five days-exposed A. obtectus adults were evaluated. The offspring production (emerged adults) was evaluated 60 days after the exposure. The results revealed that A. obtectus mortality caused by diatomaceous earth was dose, temperature and exposure period dependent. For instance, at the lowest temperature (25°C), diatomaceous earth dose (0.25g kg-1 of beans) and exposure period of two days, the efficacy of diatomaceous earth was significantly reduced when compared to the other treatments. When applied at temperatures above 30°C, the diatomaceous earth treatments always resulted in A. obtectus mortality of at least 90%. Curiously, offspring production (F1) was reduced to over 95% in all diatomaceous earth, temperatures and exposure period treatments. Therefore, the results demonstrated that diatomaceous earth has the potential to be used as a tool to manage A. obtectus infestations in stored beans, considering that such control practice.
