Tenebrio molitor and Zophobas morio are examples of agricultural pests. The purpose of this study was to determine LC50 values of tobacco extract on Tenebrio molitor and Zophobas morio. Previous research showed that tobacco extract had neurotoxin activity and nicotine was the highest content contained in the tobacco leaves. Tobacco extract was obtained by the Extended Heat Reflux Extraction method with ethanol solvent. LC50 values of tobacco extract for Tenebrio molitor and Zophobas morio were 21.1 mg/ml and 71.1 mg/ml, respectively. publisher: AIP Conference Proceedings 2193, 030021 (2019) type: Article type: PeerReviewed format: text language: en identifier: http://repository.uhamka.ac.id/id/eprint/920/1/Yogi.pdf identifier: Yogi Sentosa, Yogi dan Hannah Natasha Andjani, Natasha dan YATI, KORI dan Mahdi Jufri, Mahdi dan Haryuni, Haryuni dan Misri Gozan, Misri Determination of LC50 value of Nicotiana tabacum L. extract against Tenebrio molitor and Zophobas morio larvae.
