Bioactivities of essential oil extracted from Elsholtzia densa Benth. And its main components against Tribolium castaneum eggs and pupae

This study aimed to develop a relatively natural and safe botanical insecticide for controlling the storage pest Tribolium castaneum in the egg and pupal stages. It examined how Elsholtzia densa Benth. essential oil (EO) and its primary components, β-caryophyllene and limonene, affected T. castaneum eggs and pupae through contact and fumigation. Among th, the contact activities of β-caryophyllene against T. castaneum eggs and pupae are LD
