“…Piper aduncum caused 73-75% mortality in 24 and 48 h, respectively (Souto, 2006). It was also tested on the beetle Cerotoma tingomarianus Bechyné (Coleoptera: Chrysomelidae) and found CL50 = 0.6 mL oil cm -2 and DL50 = 0.02 mL oil cm -2 (Fazolin et al, 2005). In the present study, dillapiol treatment caused much greater mortality at both 200 and 400 μg/mL than the control in all generations and for both larvae and pupae.…”

“…However, in undamaged leaves, its percentage was slightly lower than in damaged leaves (72 and 76% respectively). The possible defense function for dillapiole is supported by the biological activities described for Piper aduncum L. leaves EOs, as antifungal and insecticide 40,41,42 . The EO of this species has also dillapiole as the major component 31 .…”

“…A associação das ligninas ao grupo metilenedioxidofenil provoca inibição da mono-oxigenase (enzima destoxificante) dependente do citocromo P450 (Bernard et al, 1990). O efeito inseticida do dilapiol pode também estar relacionado à ação de outros compostos bioativos minoritários de P. aduncum, como o safrol (Huang et al, 1999) e o sarisan (Bizzo et al, 2001), uma vez que apresentam também na sua estrutura o grupo metilenedioxidofenil (Fazolin et al, 2005).…”
