Background: The weevils produce serious damages to the stored grains, in particular to the bean. The employment of chemicalproducts in these cases constitutes a risk for the health of people for that it is necessary the search new alternatives, effectives and less toxicsAims: to determine the in vitro mortality on Acanthoscelides obtectus (Say) by three bioproducts containing powders of Azadirachta índica Juss. (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. The media were compared by the test of Tukey for P
