“…Although a majority of the studies on the toxicity of essential oils; against C. maculatus and other stored products pests; have mostly tested crude essential oils; different works with individual synthetic compounds suggest that the insecticidal activities of these essential oils are due principally to their primary constituents such as eugenol. Indeed, various studies have reported that this terpenoid has acaricidal (Ribeiro et al, 2016), insecticidal (Larson et al, 2017;Saad et al, 2018), termiticidal (Xie et al, 2015) and fungicidal (Koeduka et al, 2014) activities.…”

“…Eugenol belongs to monoterpenes, a large group of volatile and lipophilic compounds which are able to rapidly penetrate inside insects and interfere with their physiological functions (Saad et al, 2018). The mode of action of monoterpenes in insects is still not well understood although it has been studied by various authors (Soujanya et al (2016).…”

“…As a fumigant compound, the respiratory system should be the main entrance route of eugenol and other monoterpenes into the insect body, making the respiratory system the potential major target site for eugenol. In a recent study, it has been shown that eugenol have a strong inhibition of acetylcholinesterase (AChE) and adenosine triphosphatases (ATPases) activities in Sitophilus oryzae, but also that the fumigant toxicities of the monoterpenes such as eugenol are higher than their contact and/ or oral toxicities (Athanassiou et al, 2014;Saad et al, 2018). Furthermore, eugenol-rich essential oils (e.g., clove essential oil) that exhibited insecticide activity similar to the activity recorded for deltamethrin (Viteri Jumbo et al, 2018) can be easily biodegraded by microorganisms (Mishra, S. & Sachan, S. 2013;Kadacol, J.…”

The protection of stored products from insect damages, when accomplished, is mostly relying on the application of synthetic insecticides with serious health and environmental issues in addition to risks of selection of resistant insect populations associated with such practice. The use of plants derived compounds have been presented as sound strategy for sustainable insect pest management. Eugenol is an aromatic component of natural occurrence in essential oils of numerous plants. known for its repellent and insecticidal bioactivities against different insect species. Here, we investigated the fumigant application of eugenol to control the cowpea weevil Callosobruchus maculatus (Coleoptera: Chrysomelidae: Bruchinae) by assessing toxicity, effects on biological development (including emergence inhibition) and repellency to these weevil. Besides a good fumigant insecticidal activity, eugenol exposure resulted in a dose-dependent decrease of the growth rate of C. maculatus associated with a steady reduction in bean mass losses. Additionally, inhibition of offspring was upper 50% when adults were exposed to lethal and sublethal concentrations. significant inhibition of the offspring emergence was achieved after the exposure of parental adults to lethal and sublethal doses of eugenol. Furthermore, adult weevils were repelled away from beans exposed to high dose (LD99) of eugenol in contrast with their attraction to the beans treated with lower dose (LD50). Our findings suggest that eugenol has potential as control tool to be used in sustainable management startegies of C. maculatus.

“…Thus, essential oils prevent or delay the selection of resistance in insect populations as their effects are due to different modes of action. Moreover, Abdelgaleil et al (2016) attributed the insecticidal activity of essential oils to their inhibition of acetylcholinesterase or adenosine triphosphate action, as proposed by Abou-taleb et al (2016) and Saad, Abou-taleb and Abdelgaleil (2018), thus, suggesting that the latter may be the main target of essential oils.…”

The present study aimed to assess the effects of the essential oil of Croton pulegiodorus Baill on eight populations of Sitophilus zeamais Motschulsky with different patterns of susceptibility to synthetic insecticides. Populations of S. zeamais were obtained from Sete Lagoas-MG, Jacarezinho-PR, Bom Conselho-PE, Garanhuns-PE, Jupi-PE, Lajedo-PE, São João-PE and Serra Talhada-PE. To estimate the lethal concentrations (LC 50 and LC 90 ) of oil for each population, fumigation tests were performed. The susceptibility of S. zeamais to the essential oil varied among populations. Garanhuns and Bom Conselho was considered the susceptibility patterns, presenting the lowest LC 50 (3.40 μL L -1 of air) and LC 90 (9.60 μL L -1 of air) for the essential oil, respectively. The population from Jupi exhibited the highest LC 50 (14.49 μL L -1 of air) and LC 90 (19.60 μL L -1 of air) for C. pulegiodorus. The resistance ratio ranged from 1.84 for the São João to 4.26 for the Jupi population. Thus, the essential oil of C. pulegiodorus showed fumigant activity, causing mortality in all S. zeamais populations used. O ÓLEO ESSENCIAL DE FOLHAS DE Croton pulegiodorusBaill APRESENTA ATIVIDADE INSETICIDA SOBRE Sitophilus zeamais Motschulsky RESUMO -O presente estudo teve o objetivo de avaliar os efeitos do óleo essencial de Croton pulegiodorus Baill sobre oito populações de Sitophilus zeamais Motschulsky com diferentes padrões de susceptibilidade a inseticidas sintéticos. As populações foram obtidas de Sete Lagoas-MG, Jacarezinho-PR, Bom Conselho-PE, Garanhuns-PE, Jupi-PE, Lajedo-PE, São João-PE e Serra Talhada-PE. Para estimar as concentrações letais (CL 50 e CL 90 ) do óleo para cada população, foram realizados testes de fumigação. A susceptibilidade de S. zeamais ao óleo essencial variou entre as populações. Garanhuns e Bom Conselho foram considerados padrões de susceptibilidade, apresentando as menores CL 50 (3,40 μL L -1 de ar) e CL 90 (9,60 μL L -1 de ar) para C. pulegiodorus. A população de Jupi apresentou as maiores CL 50 (14,49 μL L -1 de ar) e CL 90 (19,60 μL L -1 de ar) para C. pulegiodorus. A razão de resistência variou de 1,84 vezes para população de São João a 4,26 vezes para a população de Jupi. Assim, o óleo essencial de C. pulegiodorus apresentou efeito fumigante causando mortalidade em todas as populações de S. zeamais utilizadas. Palavras-chave: Produtos naturais. Euphorbiaceae.

BACKGROUND: Botanical compounds from plant species are known to have pesticidal activity and have been used in integrated pest management programs. The varied spectrum of the pesticidal action of these compounds can also avoid selection of resistance in pest populations. In this study, mixtures of the botanical compounds geraniol, eugenol and cinnamaldehyde were encapsulated in zein nanoparticles to improve their stability and efficiency. Biological effects of the nano-scale formulations of the botanical compounds were evaluated against two agricultural pests: the two-spotted spider mite (Tetranychus urticae) and the soybean looper (Chrysodeixis includes).RESULTS: The formulations were stable over time (120 days) with a high encapsulation efficiency (>90%). Nanoencapsulation also provided protection against degradation of the compounds during storage and led to a decrease in toxicity to non-target organisms. The release of the compounds (especially eugenol and cinnamaldehyde) from the nanoparticles was directly influenced by temperature, and the main mechanism of release was through a diffusion-based process. Nanoencapsulated compounds also showed superior efficiency compared to the emulsified compounds in terms of repellency and insecticidal activity. CONCLUSION:The findings of this study indicate that the convergence of botanical compounds with nano-scale formulation has the potential to improve efficacy for their sustainable use in integrated pest management in agriculture.
