“…For insecticidal activity we found no reports in the literature, especially in P. xylostella. Jacaranda decurrens has ursolic acid as a secondary metabolite (Santos et al, 2012;Antunes et al, 2016), isolated by Varanda et al (1992), who observed the reproductive rate, survival, and population growth rate of Schizaphis graminum (Hemiptera: Aphididae) (wheat aphid), one of the main pests of wheat (Gomes et al, 2004), which decreased at direct proportion with the ursolic acid content used in the diet. Terpenes, also described for J. decurrens and J. mimosifolia (Sidjui et al, 2016), have current ecological importance as plant protection agents (Viegas Júnior, 2003).…”
