The bean weevil (Zabrotes subfasciatus) is considered the principal storage pest of beans. The objective of this work was the study of alternatives to control the Zabrotes subfasciatus in beans, using neem seed (Azadirachta indica) extract and Indian spice (Caryophyllus aromaticus L.). Four treatments were used: control; 1% aqueous neem solution (0,5ml neem oil .Kg-1 of bean seed), 25g of spice in one kg of bean seed and Gastoxin (0,011g aluminum phosphet.Kg-1 of bean seed). The experiment was installed as totally random, with four repetitions per treatment. Evaluations were done before and after application of the products, and they were live or dead adult number, number of pupae, eggs and percentage of infested seeds. Neem oil did not affected negatively Zabrotes subfasciatus, but Indian spice increase the adult death and decreased the number of laid eggs, with results similar to Gastoxin. Spice could be used as alternative to the treatment of bean seeds.
