“…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). This species stands out because of its medicinal properties; however, it is still underexploited in Brazil (SIMÕES et al, 2005).…”

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 chemical composition, antitumor activity and toxicity of the essential oil from Lippia microphylla leaves (OEL) were investigated. The major constituents were thymol (46.5%), carvacrol (31.7%), p-cymene (9%), and γ-terpinene (2.9%). To evaluate the toxicity of OEL in non-tumor cells, the hemolytic assay with Swiss mice erythrocytes was performed. The concentration producing 50% hemolysis (HC50) was 300 μg/mL. Sarcoma 180 tumor growth was inhibited in vivo 38% at 50 mg/kg, and 60% at 100 mg/kg, whereas 5-FU at 50 mg/kg caused 86% inhibition. OEL displays moderate gastrointestinal and hematological toxicity along with causing some alteration in liver function and morphology. However, the changes were considered reversible and negligible in comparison to the effects of several anticancer drugs. In summary, OEL displays in vivo antitumor activity and a moderate toxicity, which suggests further pharmacological study.

“…No Brasil, ocorre em todos os estados, representado por 82 espécies, sendo 61 endêmicas, com maior riqueza nos cerrados e campos rupestres (BFG 2015). O gênero é morfologicamente similar a Lantana, diferindo principalmente por apresentar fruto esquizocárpico, enquanto em Lantana o fruto é do tipo drupa (Santos et al 2009, Salimena 2010 Arbusto, 1-2 m alt., muito ramificado, ramos cilíndricos, tricomas glandulares capitados.

-(Verbenaceae J.St.-Hil. from the State Park of Ibitipoca, Minas Gerais, Brazil). The Parque Estadual do Ibitipoca (PEIB) is part of the Serra da Mantiqueira; it is located in the southeast of the Zona da Mata of Minas Gerais, and belongs to the Atlantic Domain, with predominance of campos rupestres (rocky grasslands) in a vegetational mosaic between altitudes of 1000 to 1784 m. This paper presents the study of the Verbenaceae family from this area, where four genera and nine species were found:
