Popis: | espanolPara evaluar el efecto biologico de los metabolitos secundarios polares y no polares de la parte aerea (hojas e inflorescencias) de Chenopodium album L. (quinoa blanca) en la alimentacion de Oryzaephilus surinamensis L. (Coleoptera: Silvanidae) se desarrollo un ensayo donde material vegetal previamente secado y triturado se sometio a extraccion continua primero con eter de petroleo y luego con metanol, finalmente se realizo una extraccion con agua en �batch� del material remanente dando origen a los correspondientes extractos. Se impregnaron 2 g de dieta base con solucion de los extractos etereo, metanolico y acuoso, en una concentracion de 66 mg/ml. En los tratamientos control se utilizo eter de petroleo metanol y agua, respectivamente. Se realizaron seis tratamientos en un diseno completamente aleatorizado, con cuatro repeticiones, analizandose el comportamiento y evolucion de los insectos y el ciclo biologico de las larvas resultantes de los mismos. Cada siete dias se determino el numero de individuos adultos y larvas vivas. Todos los datos fueron evaluados por ANOVA y las diferencias entre medias fueron verificadas por el test de Tukey (p EnglishThe present assay was performed in order to evaluate the biological effects of polar and non-polar metabolites form the aerial parts of (leaves and inflorescences) Chenopodium album L. (white quinoa) on Oryzaephilus surinamensis L (Coleoptera: Silvanidae) feeding. Previously dried and ground plant material was submitted to sequential continuous extraction with petroleum ether and then with methanol; the remaining plant material was finally extracted in batch with water, giving rise to the corresponding extracts. 2 g of basic diet were impregnated with 66 mg/ml solutions of ether, methanol or aqueous extracts. Petroleum ether, methanol and distilled water were used respectively as control treatments. Six treatments were performed in a completely randomized design with four repetitions, analyzing insect behavior and the evolution of the biological cycle of the resulting larvae. The number of living adults and larvae was determined every seven days. All treatments were evaluated by means of ANOVA, and differences between mean values using Tukey`s test. (p |
