“…leaf EO showed contact effect against T. castaneum , indicating a low LD 50 /LC 50 value (12.13 μg/adult and 104.67 μg/cm2, respectively) 66 . The fumigant studies with C. austroindica and C. aromatica EOs showed higher toxicity against T. castaneum at the exposure time of 24 h (LC 50= 35.65 & 29.10 μL/L), respectively 67 . Pervious study reported better contact activity for Thymus capitatus and Origanum compactum against T. castaneum .…”

The thrust of the study was to determine the chemical composition of the essential oils extracted from Thymus pallescens de Noé and Cymbogon citratus Stapf. as well as to evaluate their efficacy in controlling Sitophilus zeamais Motschulsky and Tribolium castaneum (Herbst) in either single or combined populations. Carvacrol (56.04%) and geraniol (20.86%) were identified as the major constituents of T. pallescens and C. citratus respectively. The tested essential oils showed pronounced insecticidal activity against the pest species in relation with the applied doses. T. pallescens EO had the highest efficacy and S. zeamais was found to be more susceptible to both individual and combined treatments. With reference to the contact and fumigation assessments, T. pallescens EO effectuated corrected mortality rates ranging from 42.5–100% to 25–100% in S. zeamais with corresponding lethal concentration (LC50) values of 17.7 µl/ml and 15µL/L air respectively. Whereas, the T. pallescens EO exhibited corrected mortality rates of 42.5–100% and 20–100% with corresponding LC50 values of 18.1 µl/ml and 15.5 µL/L air against T. castaneum in contact and fumigation assessments, respectively. The corrected mortality rates increased for both insect species when using combination treatments, with significant increases in the LC50 values, ranging from 8.59 to 49.9% for both pest species. Analysis of energy biomarkers in the treated insects indicate significantly increased protein and carbohydrate contents and decreased lipids levels. The study therefore demonstrated the bio-insecticidal toxicity of the EOs from T. pallescens and C. citratus against two important maize post-harvest pests, concurrently revealing significant positive and negative insecticidal activity gradients in relation to single or combined populations.

“…(1996) reported the presence of E-anethole as the major component in C. heptaphylla essential oil with 98.2% in leaf essential oil at both fruiting and flowering stage while 61.67% anethole was revealed in fruit essential oil. Some investigation also reported that other species of Clausena like C. anisate , C. austroindica and C. harmandiana possesses anethole (80.00–97.44%) as major component in leaf essential oil ( Addae-Mensah et al., 1996 ; Johnson et al., 2022 ). Another report mentioned that C. indica essential oil was rich in myristicin (35.3%) content ( Diep et al., 2009 ) while C. pentaphylla yielded 0.80% essential oil having methyl eugenol (38.1%) as the principal volatile constituent ( Pandey et al., 2012 ).…”

IntroductionAnethole is an industrially important compound which is extensively used in pharmaceuticals, cosmetics, perfumery, food and confectioneries. Anethole is primarily obtained from fennel, anise, and star anise which is highly expensive. Therefore, a study was performed to identify a cost-effective and natural anethole rich strain of Clausena heptaphylla through selection and confirmed through multilocation trial.MethodsThe study was conducted using 23 accessions collected from North eastern region of India from 2014-2018 (initial evaluation trial) and 2018-2022 (multilocation trial). The initial trial was conducted in the experimental farm of CSIR-NEIST, Jorhat, Assam using Complete Randomized Block Design with three replications. Five agronomical traits (plant height, leaf length, leaf width, number of stem branching, herbage yield per plant per cutting) along with essential oil yield and anethole content were evaluated which led to the identification of anethole rich strain of C. heptaphylla. This identified strain was further evaluated along with the two check genotypes for stability based on three yield parameters viz. herbage yield, essential oil yield and anethole content at four multi-locations (Imphal, Jorhat, Runne and Madang) for four years using the same experimental design.Results and discussionThe identified superior line (Jor Lab CH-2) showed consistent performance for the studied yield parameters across all the environments maintaining its superiority. The identified strain exhibited average herbage yield of 1.2 Kg/plant/cutting and essential oil yield of 1.22%. The GC-MS analysis of the essential oil depicted trans anethole as the major constituent (93.25%) followed by estragole (4.85%) while benzene, 1,2-dimethoxy-4-(1-propenyl Isoeugenol methyl ether and cis-anethole were the trace components. This is the first novel report of anethole rich variant of C. heptaphylla which has undergone multilocational trial over the years. Jor Lab CH-2 strain will open a new scope for the industries to isolate anethole from a different source in a cost-effective approach.

“…The most effective natural compound identified was trans-anethole (LD 50 = 0.027 mg/g of insect), followed by citronellal (LD 50 = 0.07 mg/g of insect). Trans-anethole has been widely reported for its toxic effects on arthropod pests such as N. ribisnigri , the currant-lettuce aphid, T. castaneum , S. oryzae , Hyphantria cunea , the American white moth, and Cryptolestes ferrugineus [ 30 , 89 , 90 , 91 , 92 ]. Both linalool and thymol were tested by different authors using the same method, but with dissimilar results being reported.…”

Spodoptera frugiperda is a major pest of maize crops. The application of synthetic insecticides and the use of Bt maize varieties are the principal strategies used for its control. However, due to the development of pesticide resistance and the negative impact of insecticides on the environment, natural alternatives are constantly being searched for. Accordingly, the objective of this review was to evaluate the use of essential oils (EOs) as natural alternatives for controlling S. frugiperda. This review article covers the composition of EOs, methods used for the evaluation of EO toxicity, EO effects, and their mode of action. Although the EOs of Ocimum basilicum, Piper marginatum, and Lippia alba are the most frequently used, Ageratum conyzoides, P. septuplinervium. O. gratissimum and Siparuna guianensis were shown to be the most effective. As the principal components of these EOs vary, then their mode of action on the pest could be different. The results of our analysis allowed us to evaluate and compare the potential of certain EOs for the control of this insect. In order to obtain comparable results when evaluating the toxicity of EOs on S. frugiperda, it is important that methodological issues are taken into account.
