Insecticidal efficacy and physiological effects of Eucalyptus globulus essential oil and its constituent, 1,8-Cineole against Tribolium confusum (Jacquelin du Val, 1868) (Coleoptera, Tenebrionidae)

Chemical profiling and bioactivities of essential oils from Thymus capitatus and Origanum compactum against Tribolium castaneum

“…Thymol was reported in another study as the most effective feeding intake inhibitor out seven tested monoterpenes [ 51 ] . The antifeedant effect of both EOs might be attributed to the reduction in digestive enzymes, such α-amylase, protease, and lipase, which are crucial for insects [ 52 ]. Additionally, the antifeedant effect might involve the implication of olfactory and gustative binding protein, which exhibit a repellent effect on insects, preventing them from feeding [ 53 , 54 ].…”
