“…Essential oils are seen as alternatives to the use of conventional insecticides, Lamiaceae being one of the main botanical families with regard to aromatic compounds and with several species that have insecticidal activity (Park et al, 2016;Yeom et al, 2018). In addition, essential oils have advantages such as, they can be obtained on a large scale and from several plants, they have several modes of action which make the development less Development, v. 9, n. 9, e72996412, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i9.6412 resistant, they are relatively less toxic to mammals and do not leave residues due to its high volatility (Park et al, 2016).…”

Plants are considered a rich source of bioactive compounds and an alternative agent for insect control. Among them, representatives of the Lamiaceae family are the best known for this potential, as they produce volatile compounds with insecticidal activities, known as essential oils, as is the case with Ocimum gratissimum. In this way, the present work had as objective, to determine the chemical composition of the oil of the leaves of O. gratissimum and its potential insecticide against the cockroach Nauphoeta cinerea. For that, the essential oil was chemically characterized by means of a Gas Chromatograph coupled to a Mass Spectrometer (GC/MS). As for the insecticidal action, nymphs (20 days of age) were used and the fumigation methodology was used in concentrations ranging from 50 to 1000 μg of oil per mL of air. Mortality rates were observed every 12 hours for 1 day. The results showed that the essential oil has insecticidal properties, since it had a median lethal concentration (LC50) of 516 µg/mL. Such property may be related to the heterogeneous composition of the oil, which had 12 terpenic compounds, with 1.8 Cineole being the major compound (30.04%). Thus, the essential oil of O. gratissimum has an insecticidal activity and can be used to fight pests, as in the case of cockroaches.

“…The German cockroach, Blatella germanica L. (Blattodea, Blattellidae), is a synanthropic and cosmopolitan pest, that causes allergic reactions in sensitive people (Yeom et al, 2018). These cockroaches also act as mechanical vectors of microorganism from the genus Escherichia, Entamoeba, Giardias and others (Dietrich et al, 2014;Werdin González et al, 2016).…”

“…These cockroaches also act as mechanical vectors of microorganism from the genus Escherichia, Entamoeba, Giardias and others (Dietrich et al, 2014;Werdin González et al, 2016). The overuse of synthetic insecticides like organophosphates and pyrethroids to control B. germanica populations has led to serious problems including impacts to non-target organisms, pest resistance and contamination of terrestrial and aquatic environments (Campos et al, 2018;Kah et al, 2018;Yeom et al, 2018). Development of eco-friendly strategies have been considered around the world to replace these conventional pesticides.…”

Western flower thrips (Frankliniella occidentalis; Thysanoptera: Thripidae), or WFT, are a global pest of commercial crops, particularly those grown in greenhouses. Current management recommendations often involve judicious use of pesticides to which WFT have evolved multiple resistance phenotypes. Essential oils (EOs) have shown promise as a less toxic alternative for WFT greenhouse management. However, challenges remain in predicting which EOs are most likely to be insecticidal to WFT and ensuring that the efficacy of EOs under bioassay conditions reflect performance in whole-plant application scenarios. To address these challenges, 9 EOs were tested for contact toxicity against WFT in small container assays, then gas chromatography–mass spectroscopy (GC–MS) profiles of each EO were used to quantify concentrations of 22 chemicals shared by at least 5 or more of the plant species. Of these, 13 compounds were positively correlated with thrips mortality. Effective compounds were a mixture of sesquiterpenes, cyclic monoterpenes, and noncyclic monoterpenes. Interestingly, no bicyclic monoterpenes shared among the essential oils tested correlated with thrips mortality. Whole-plant assays of the four best EOs from the container assay showed significant reduction in the number of thrips per plant, although mortality in EO treatments in the whole plant assay was lower than in the container assay. In addition, all four EOs were as efficacious as the conventional insecticide flonicamid. Identifying other EOs with high concentrations of the efficacious compounds that were identified in this study and using container assays to screen these oils for WFT thrip mortality and phytotoxicity could help integrated pest management (IPM) practitioners and greenhouse staff to more rapidly accumulate a suite of EOs as low toxicity alternatives for management of WFT in greenhouse settings.
