Metabolization of Insecticidal Amides from Leaves of Piper tuberculatum by Heraclydes hectorides and Naupactus bipes

Journal of the Brazilian Chemical Society, 2020
Amides have been recognized as potent insecticidal natural products but, despite their variety of targets and mechanisms of action, their metabolic fate in insects is virtually unknown. The currently accepted hypothesis is that specialist herbivores are capable of biotransforming xenobiotics rendering them more polar and excretable while generalist ...
