Insecticidal activity of Vitex cymosa (Lamiaceae) and Eschweilera pedicellata (Lecythidaceae) extracts against Sitophilus zeamais adults (Curculionidae)

This study evaluated insecticidal and repellent effects of Vitex cymosa and Eschweilera pedicellata extracts against Sitophilus zeamais adults. Contact on filter paper discs and contaminated grain ingestion assays were performed. The repellent effect was evaluated with the "preferential area" method...
