Última Bioactivity of the organic extracts of Annona vepretorum on Tetranychus urticae (Acari: Tetranychidae) PAB Fernandes,Maria Herlândia de Araújo; Menezes,Karen Oliveira de; Souza,Adriana Maria de; Almeida,Jackson Roberto Guedes da Silva; Oliveira,José Eudes de Morais; Gervásio,Rita de Cássia Rodrigues Gonçalves. Abstract: The objective of this work was to evaluate the lethal and sublethal toxicity of hexane and methanolic extracts from the leaves of Annona vepretorum (Annonaceae) on Tetranychus urticae (Acari: Tetranychidae). The methanolic extract toxicity was evaluated by Potter tower application (topical + residual effect) and by immersion of Canavalia ensiformis leaf disks in the extract solution (residual contact effect). The hexane extract toxicity was evaluated exclusively through residual contact effect. Sublethal effects of the methanolic extract were evaluated through LC50 on the females. Mite preference for feeding and oviposition was evaluated by multiple choice tests, between the control and the extract concentrations, using the hexane and methanolic...

Abstract: The objective of this work was to evaluate the phytochemical profile and bioactivity of extracts of Brazilian stinging (“cansanção”) nettle (Cnidoscolus urens) on cabbage caterpillar (Ascia monuste orseis). Mortality, larval stage duration, pupal viability and mass, percentage of deformed pupae, and feeding preference were evaluated. The constituent classes of the ethanolic extracts were also identified by analytical thin-layer chromatography (TLC). Ethanolic extracts of leaves and roots at 2% (m/v) and aqueous extract of roots at 20% (m/v) prolonged the larval phase of the insect. The ethanolic extract of leaves at 2% reduced pupal viability, and pupae from all treatments showed reduced masses and generated deformed adults. Except for the...
