Extract against Gryllus bimaculatus Imago and Galleria mellonella Larvae ID - repository831 AV - public UR - https://doi.org/10.1063/1.5139361 N2 - Replacement of synthetic pesticide with natural pesticide is highly demanding because it is more environmentally friendly. Tobacco is majorly exploited for cigarettes production. Therefore, it needs to be developed for other alternative products, one of which is insecticide due to nicotine content and other toxic compounds. This research aimed to determine the effectiveness of tobacco as an insecticide for Galleria mellonella and Gryllus bimaculatus. The raw material used in this study was the leaf extract of Nicotiana tabacum L., var. Virginia that was obtained by Ethanolic Heat Reflux Extraction (EHRE) technique. After testing on the insects, LC50 values were 36.6 mg/ml for Galleria mellonella and 38.5 mg/ml for Gryllus bimaculatus. ER -
