Conteúdo: | Products made from piperine are important for the management of pests, but allelopathic studies for these products are also relevant. The aims of the study were: First, to evaluate the effect of piperine on Spodoptera frugipera and Diatraea saccharalis and as second objective, to evaluate the allelopathic and phytotoxicity effects of this compound in the germination and growth of several vegetables. The piperine was applied on eggs laid by both lepidopteran species and on sand used as a substrate for the seeds plants. The hatching in recently laid eggs of S. frugiperda and D. saccharalis with piperine was lower than older eggs. Allium cepa presented a higher percentage of germination at 0.5 and at 5.0 mg/Kg and Lactuca sativa the lowest. The highest length of seedling was for the A. cepa. The piperine shows biological impact on eggs of S. frugiperda and D. saccharalis as well as in the germination and Products made from piperine are important for the management of pests, but allelopathic studies for these products are also relevant.
