“…The observed results against T. castaneum and L. bostrychophila were consistent with previous reports [36,37,38]. The investigation of bioactivities of the Litsea cubeba and Etlingera yunnanensis and the individual compounds demonstrated the contact and repellent activities of α-pinene and d -limonene against L. bostrychophila [37,38].…”

Abstract:The chemical composition of the essential oil from Juniperus formosana leaves and its contact and repellent activities against Tribolium castaneum and Liposcelis bostrychophila adults were investigated. The essential oil of J. formosana leaves was obtained by hydrodistillation and analyzed by GC-MS. A total of 28 components were identified and the main compounds in the essential oil were α-pinene (21.66%), 4-terpineol (11.25%), limonene (11.00%) and β-phellandrene (6.63%). The constituents α-pinene, 4-terpineol and D-limonene were isolated from the essential oil. It was found that the essential oil exhibited contact activity against T. castaneum and L. bostrychophila adults (LD 50 = 29.14 µg/adult and 81.50 µg/cm 2 , respectively). The compound 4-terpineol exhibited the strongest contact activity (LD 50 = 7.65 µg/adult). In addition, data showed that at 78.63 nL/cm 2 , the essential oil and the three isolated compounds strongly repelled T. castaneum adults. The compounds α-pinene and D-limonene reached the same level (Class V) of repellency as DEET (p = 0.396 and 0.664) against L. bostrychophila at 63.17 nL/cm 2 after 2 h treatment. The results indicate that the essential oil and the isolated compounds have potential to be developed into natural insecticides and repellents to control insects in stored products.

“…EO against Sitophilus zeamais and Sitophilus oryzae (pests of stored cereals), with LC 50 value of 308.11 and 163.55 mg/cm 2 for the insecticidal effect (contact), respectively, and strong insect repellent properties at 13 nL/cm 2 . A similar approach regarding the evaluation of EOs as insecticide and insect repellent can be encountered in the studies published in the same year (2015), by Martínez-Evaristo et al [26], Aguiar et al [27], de Lira et al [28], Guo et al [29], Haider et al [30], Wu et al [31], Yang et al [32], You et al [33], and Zhang et al [34] (details provided in Table 1). Among these articles, the work of Haider et al [30] presents the variation in composition and effect of the EO of Tanacetum nubigenum Wallich.…”

Abstract The overuse of synthetic pesticide, a consequence of the rush to increase crop production, led to tremendous adverse effects, as they constitute a major pollutant for both soils and water, with a high toxicity towards humans and animals and, at the same time, led to development of pest resistance. In the last period, the researches were directed towards finding new solutions with a lower toxicity, less damaging behaviour towards the environment, and a better specificity of action. In this context, the use of essential oils, a complex and unique mixture of compounds, can be considered for the next-generation pesticides. This review aims to present the main applications of the essential oils as insecticides, herbicides, acaricides, and nematicides, as they emerged from the scientific literature published in the last 5 years (2015 to present). From the identified articles within the time period, only those dealing with essential oils obtained by the authors (not commercially available) were selected to be inserted in the review, characterized using established analytical techniques and employed for the envisaged applications. The review is concluded with a chapter containing the main conclusions of the literature study and the future perspectives, regarding the application of essential oils as next-generation pesticides.

“…As our knowledge, this is the first work that evaluates the influence of these food grade antioxidants (free and microencapsulated) against O. surinamensis and T. castaneum. Some works reported LT 50 and LD 50 values of this insect but they always used free compounds as commercial insecticides and essential oils [17][18][19][20][21][22][23][24].…”
