Basil (Ocimum basilicum) is a popular culinary herb throughout the world. Essential oil derived from basil (basil oil) has shown to be a potent biopesticide and food preservative (Li and Chang, 2016). Basil oil contains more than 200 chemicals such as linalool, estragole, and eugenol. The U.S. Food and Drug Administration (FDA) and European Commission have accepted and classified the components from basil (O. basilicum) oil as generally recognized as safe (GRAS). Carvacrol, linalool, and pulegone showed excellent potency against thrips, melon fly, and turnip aphids (Sampson et al., 2005). Basil oil and its major components trans-anethole, estragole, and linalool are very potent against adult fruit flies Ceratitis capitata, Bactrocera dorsalis, and Bactrocera cucurbitae (Chang et al., 2009). Electrophysiological studies indicated that linalool inhibits both mammalian γ-aminobutyric acid type A receptor (GABAAR) and nicotinic acetylcholine receptor (nAChR) (Li et al., 2020), which may explain its insecticidal activity. Linalool is a concentration-dependent, noncompetitive inhibitor on the GABAAR. The half maximal inhibitory concentration (IC50) of linalool on the GABAAR and nAChR was approximately 3.2 and 3.0 mM, respectively (Li et al., 2020).

Anethole (1-methoxy-4-propenyl-benzene, isoestragole) is an alkoxypropenylbenzene derivative and an important flavoring component of the essential oils of more than 20 plant species.8 Anethole is commonly used as a flavoring agent in the food, beverage, cosmetic and medical liquids industries. Worldwide, traditional uses of plants that contain anethole include mainly antioxidant,9–11 anti-inflammator,12 antithrombotic,13 anesthetic,14 healing,15 and anti-carcinogenic9 substances, as well as and relaxing agents with effect on aortic rings.16,17
