Abstract

Abstract: Botanical extracts are a plentiful resource of molecules with different biological activities, such as insecticides and antimicrobial pesticides. In this context, the aim of this work was to evaluate the efficacy of botanical extracts from the Brazilian savannah against Diabrotica speciosa and bacterial strains isolated from the gut of this insect under aseptic conditions. The bacterial isolates were identified by genomic and proteomic approaches, and bioassayed against eighteen botanical extracts in vitro. The best results of bacterial inhibitions were obtained for the extracts of Casearia sylvestris and Psidium laruotteanum . Fractions of C. sylvestris and P. laruotteanum, quantitatively evaluated by chromatographic analyses, showed a relationship between the bactericidal activity and phytochemical profile. In vivo assays showed that P. laruotteanum was also effective for the control of D. speciosa . Those results show that selected natural products can have both antimicrobial and insecticidal activities.
