Estudo do potencial de Jatropha curcas L. (Euphorbiaceae) sobre o manejo da cochonilha da roseta

Abstract: O alto custo socioeconômico e ambiental dos agroquímicos proporcionou a busca de alternativas eficientes e ecologicamente compatíveis no controle de pragas. O emprego de produtos derivados de plantas torna-se uma alternativa promissora. Devido à utilização indiscriminada de produtos não registrados para o controle de Planococcus citri, objetivou-se avaliar no presente trabalho o potencial de uso de Jatropha curcas. Foram utilizados indivíduos com 10, 15, 20 e 25 dias de idade. As concentrações usadas no experi… Show more

“…Likewise, Holtz et al (2016) determined that all Jatropha curcas organs have potential in the control of Planococcus citri in coffee culture. Holtz et al (2022) reported that the extract from Jatropha curcas leaves control infestation by Myzus Persicae and determined that the age or maturity of leaves influence the insecticidal activity due to the greater or lesser concentration of secondary metabolites.…”

“…Curcine is a toxic protein that has a combined anti-food and insecticidal activity. The anti-food activity is due to the inhibition of the enzyme α-amylase in the body, preventing the absorption and digestion of starch by insects, while the insecticidal activity consists of the action of RIP to cause death of the cells of the gastrointestinal tract after ingestion [22]. The activity of the diterpene esters is broad and can affect insects in different ways.…”
