(neem), Melia azedarach L. (paradise) y Eucalyptus sp. (eucalipto)Settings and Design: Three assay with totally randomized designs were carried out with four treatments and four repetitions (Petri dish). The treatments were constituted by three concentrations (25, 50 and 75%) of each bioproduct and a controlMethods and Material: For the assays, adults of A. obtectus were fed with beans. The percentage of mortality was determined at the 48, 72 and 168 hours after the treatment with the phytopesticideStatistical analysis used: Data were transformed in arcsen √x, and they were processed by means of a variance analysis, using the statistical package SPSS version 15.
