Insecticidal activity of monoamide compounds from <i>Humulus scandens</i> against <i>Spodoptera frugiperda</i>.

ABSTRACT: Spodoptera frugiperda, a globally invasive pest, currently lacks effective control measures beyond certain chemical pesticides. Previous reports have demonstrated the effectiveness of Humulus scandens against various agricultural pests. Here, our aim was to derive toxic compounds and explore the insecticidal potential of the botanical plant H. scandens against S. frugiperda. Through activity-guided isolation, two monoamide compounds, N-p-coumaroyl tyramine (1) and N-trans-feruloyl tyramine (2), were identified from the EtOAc extract of H. scandens. The results showed that both compounds 1 and 2 exhibited good insecticidal effects on S. frugiperda under both contact and dietary toxicity methods, with
