Use of indole derivatives as an alternative for the control of populations of Sitophilus zeamais

Abstract

Sitophilus zeamais is an important stored-grain pest that causes major damage worldwide. Control of this insect is hampered by increasing resistance to conventional insecticides. An alternative to overcome this problem is the search for new insecticidal compounds. Faced with this is the search for new compounds that are efficient in controlling this pest and that reduce environmental risks and non-target organisms. In this work, we aimed to analyze the effects of indole derivatives in three populations of S. zeamais, from the cities of Aracaju-SE, Jacarezinho-PR and Sete Lagoas-MG. In these populations seven compounds were tested, being compounds 2f, 2e and 2d more toxic to S. zeamais. The results demonstrated the potential of the indole derivatives as a tool for the generation of new insecticidal products for the control of S. zeamais.
