“…The insecticidal activity of EO of L. alba is attributed to the linalool component (NICULAU et al, 2013), whereas for EO of L. gracilis, it is attributed to thymol and carvacrol (MELO et al, 2018). Although the components mentioned belong to the chemical profile of EO of L. microphylla, its major components in this study were E-caryophyllene and E-nerolidol, respectively.…”

“…The EO of L. microphylla also provided high mortality rates; however, it was more efficient in topical applications. EOs of other species of this genus were efficient, such as L. alba in the control of S. frugiperda (NICULAU et al, 2013) and L. gracilis to control Diaphania hyalinata (LINNAEUS, 1767) (Lepidoptera: Pyralidae) (MELO et al, 2018). L. microphylla is a shrub with simple leaves with serrated edges and printed veins (LORENZI; MATOS, 2008), which occurs throughout Brazil in the Tableland Forest, open forests, Caatinga and Cerrado (SANTOS et al, 2009).…”

“…Aspects of selectivity should be observed when using EO to non-target organisms. According to MELO et al (2018) the EO of L. gracilis was not selective for the bee Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae) and the predatory wasp Polybia micans Ducke, 1904 (Hymenoptera: Vespidae). The EO of C. citriodora may present negative effects on pollinators (FILOMENO et al, 2017), which is harmful for Tetragonisca angustula Latreille (Hymenoptera: Apidae); however, it is harmless to Solenopsis saevissima Smith (Hymenoptera: Formicidae) (RIBEIRO et al, 2018).…”

Insecticidal activity of essential oils in controlling fall armyworm, Spodoptera frugiperda

et al. 2019

Fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is one of the main pests in maize crop with developing resistance to chemical products and Bt technology. Therefore, alternative control methods such as essential oils are important steps in the implementation management strategies for this pest. This study aimed to evaluate the efficiency of essential oils (EOs) of Corymbia citriodora, Myrciaria dubia (Myrtaceae), Lippia microphylla (Verbenaceae) and Piper umbelattum (Piperaceae) in controlling S. frugiperda. The OEs were extracted and mortality tests were conducted with topic and volatile applications, in 30 second-instar caterpillars originated from insect rearing and artificial diet. As a control, we conducted tests with distilled water and acetone. EOs that provided mortality rates above 80% were submitted to chemical analysis for constituent identification. The efficient EOs were only those of C. citriodora and L. microphylla. For EO of C. citriodora, the LD80 was 7.06 ± 0.73 mg.g -1 in topical application and 5.85 ± 0.75 μL via volatile application. On the other hand, for EO of L. microphylla, DL80 was 9.95 ± 1.25 mg.g -1 in topical application and 18.56 ± 3.55 μL via volatile application. Chemical analysis showed that the main constituents were citronella for the EO of C. citriodora and (E)-caryophyllene and (E)-nerolidol to the EO of L. microphylla. EOs of C. citriodora and L. microphylla are promising for controlling S. frugiperda, with emphasis on the volatile effect of C. citriodora oil.

“…The authors attributed this activity to their high thymol content and synergistic effects of p-cymene and thymol methyl ether. Tests using different chemotypes of L. gracillis against Diaphania hyalinata (Lepidoptera: Pyralidae) demonstrated that chemical races consisting primarily of the phenolic terpenes thymol and carvacrol were more toxic (Melo et al, 2018). Essential oil of L. origanoides Kunth, rich in carvacrol and p-cymene, was also efficient at controlling Aedes aegypt Linn, Tetranychus urticae Koch.…”

Lippia is one of the main genera in the family Verbenaceae, with 200 species described. Despite its richness in bioactive molecules, with several scientifically proven applications, there is little information on the insecticidal potential of its species. This study aimed to assess the insecticidal potential of essential oils from the species Lippia thymoides (Martius & Schauer); Lippia lasiocalycina (Schauer) and Lippia insignis (Moldenk) against Nasutitermes corniger (Motschulsky) (Isoptera-Termitidae). Insecticidal activity was evaluated by exposure to a contaminated surface, whereby plastic pots were lined with filter paper and imbibed in 1.5 ml of solution containing essential oils (10 µl/ml), with 10 N. corniger specimens per pot. The mortality count was performed at 24 and 48 h. The LC50 was determined by diluting the essential oils to concentrations of 0, 0.625, 1.25, 2.5, 5.0 and 10 µl/ml, which were chemically analyzed by GC-FID and GC-MS. The data indicated high toxicity for the essential oils for the Lippia species tested. The lowest LC50 (0.46 µl/ml) was recorded for L. lasiocalycina. The most common constituents were β-myrcene and (E)-ocimenone in essential oil of L. lasiocalycina, β-myrcene and limonene for L. insignis, and (E)-caryophyllene and caryophyllene oxide for L. thymoides. The results demonstrate the viability of developing biopesticides for N. corniger control.

“…Carvacrol or plant extracts with carvacrol as the main component are known to exert negative effects against coleopteran (Szczepanik et al 2018), homopteran (Zekri et al 2016), dipteran (Andrade-Ochoa et al 2018;de Mesquita et al 2018;Giatropoulos et al 2018), lepidopteran (Melo et al 2018), neuropteran (Castilhos et al 2018), and hemipteran (Gaire et al 2019;Rizvi et al 2018) insects. This phytochemical was shown to exhibit contact (Castilhos et al 2018;Melo et al 2018;Rizvi et al 2018), repellent (Giatropoulos et al 2018), and fumigant (Gaire et al 2019) toxicity. The carvacrol-containing essential oil showed neurotoxic effects and was found to inhibit the acetylcholinesterase enzyme in the contact application against insect pests (de Mesquita et al 2018;Rizvi et al 2018).…”

Synergistic interaction between carvacrol and Bacillus thuringiensis crystalline proteins against Cydia pomonella and Spodoptera exigua

et al. 2020

The aim of our study was to determine the usefulness of mixtures of carvacrol and Bacillus thuringiensis crystalline proteins Cry against pests of two different species: Cydia pomonella L. (Lepidoptera: Tortricidae) and Spodoptera exigua Hübner (Lepidoptera: Noctuidae). The novelty of our work lies in showing the interactions between carvacrol and bacterial toxins against insect pests. Moreover, we have demonstrated that carvacrol applied via ingestion exerts toxicity against lepidopteran caterpillars. We have shown that the botanical compound and Cry proteins act in synergy and their mixtures are most effective in reducing the number of L1 and L3 larvae when B. thuringiensis toxins constitute up to 0.1% and 0.05% of the mixtures, respectively. Carvacrol and crystalline proteins act in synergy in these combinations and have the potential to be effective in protecting crops against lepidopteran pests. The nature of the interaction between the components depended on the proportion of their concentrations in the mixture. Mixtures containing Cry toxin concentrations equal or higher than 20% caused lower observed mortality of insects compared to the expected one. Furthermore, we showed that crystalline proteins of B. thuringiensis MPU B9, carvacrol and their mixture did not affect the morphology of insect haemocytes, and additionally, had no effect on the immune system.
