Bioactivity of Annona montana Macfad extracts on the black cowpea aphid (Aphis craccivora Koch)

Abstract: This study aimed to verify the insecticidal activity and determine the LC 50 of hydroethanolic extracts from Annona montana leaves and seeds on the black aphid, Aphis craccivora. The experiment was conducted in a greenhouse. Annona montana leaf and seed extracts were obtained by solvent extraction using 70% ethanol. The following spray treatments were applied on the black aphid nymphs: Hydroethanol (HE) extracts from leaves at concentrations of 2.5; 5; 10; 15%, and EH extracts from seeds at 0.5; 1.0; 1.5; 2%; … Show more

“…These results reinforce the evidence that for the species Metreodora flavida, the lowest concentration tested was able to control at least 50% of the Aphis craccivora population, while the species Cheiloclinium cognatum and Tetragastris altissima require higher concentrations in the 72 hours period. A study carried out by Bandeira et al (2017) obtained an LC50 of 7,69% after 48 hours of application of the hydroethanolic extract of Annona montana, on Aphis craccivora under greenhouse conditions. The lethal concentrations calculated for the alcoholic extract of the species studied after 72 hours under laboratory conditions were smaller when compared with those obtained by Bandeira et al (2017), but in a longer evaluation period.…”

“…Na concentração de 15%, o extrato hidroetanólico de folhas causou 78% de mortalidade e CL 50 = 7,69%, enquanto o extrato obtido de sementes foi eficiente na concentração de 2%, proporcionando 96% de mortalidade das ninfas, com CL 50 = 0,55%. Ambos os extratos são indicados no controle de pulgão preto do feijão-caupi (BANDEIRA et al, 2017). ± 6,3.…”
