“…Mendonça et al (2005) described the lethal concentration (CL 50 ) to be 14.5 mg L -1 ; Shaalan et al (2005) suggested 10 mg L -1 ; Asogwa, Mokwunye, Yahaya, and Ajao (2007) cited 100% mortality at 60, 80, and 10 mg mL -1 concentrations; and Porto et al (2013) recently used a base formulation of CNSL in concentrations of 0.002 to 10 mg mL -1 . Unfortunately, the reforestation and forestry programs of A. occidentale in various regions of Brazil do not consider some inherent family characteristics.…”

ABSTRACT. Cashew (Anacardium occidentale) nut shell liquid (CNSL) has been successfully used in trials as an Aedes aegypti larvicide, but little is known about its environmental effects. In this study, the potential effects of CNSL and a CNSL-based phyto-product formulation on the germination and growth of Lactuca sativa (lettuce), Lycopersicon esculentum (tomato) and Senna obtusifolia (coffee senna) were assessed. The pH of CNSL and the formulation were 6.4 and 6.8, respectively; the electrical conductivities were 2.89 μS cm -1 (CNSL) and 2.21 μS cm -1 (formulation), respectively, and both contained anacardic acid (53.2%) and degradation products. In bioassays for germination and growth, CNSL (25, 50, 100, 150, and 200 mg mL -1 ), the formulation (100 mg mL -1 ) and the control were used in a completely randomized design. The results demonstrated the chemical effects of CNSL, which negatively affected the germination and vigor of lettuce and tomato and the vigor of coffee senna; for growth, it negatively influenced both the root and aerial parts of lettuce and tomato, but only the roots of coffee senna. The formulation had negative effects on the vigor of coffee senna and the growth of tomato and lettuce seedlings (roots and aerial parts). The results indicate the phytotoxicity of CNSL and the formulation for the plant species tested.Keywords: Anacardiaceae, Anacardium occidentale, CNSL, anacardic acid, allelopathy.Líquido da casca da castanha de caju e formulação: toxicidade sobre sementes de alface, tomate e fedegoso e formação de plântulas RESUMO. O líquido da casca da castanha de caju (LCC) de Anacardium occidentale está sendo utilizado com sucesso em ensaios larvicidas para Aedes aegypti; porém pouco se sabe sobre seus efeitos ambientais. Neste trabalho, o objetivo foi avaliar os efeitos do LCC e de um fitoproduto a base de LCC na germinação e no crescimento de Lactuca sativa (alface), Lycopersicon esculentum (tomate) e Senna obtusifolia (fedegoso). O pH do LCC e formulação é 6,4 e 6,8, respectivamente; a condutividade elétrica 2,89 μS cm -1 (LCC) e 2,21 μS cm -1 (formulação) e ambos contêm ácido anacárdico (53,2%) e produtos de degradação. Nos bioensaios de germinação e de crescimento, utilizou-se LCC (25, 50, 100, 150 e 200 mg mL -1 ) e a formulação (100 mg mL -1 ) e controle, com delineamento inteiramente casualizado. Os resultados demonstraram efeito do LCC, afetando negativamente a germinação e vigor da alface e tomate e o vigor do fedegoso; no crescimento, influenciou negativamente o crescimento da raiz e caule de alface e tomate e no fedegoso, apenas da raiz. A formulação exerceu efeito negativo apenas para sementes de fedegoso e afetou negativamente o crescimento das plântulas de alface e tomate, raiz e parte aérea. Os resultados obtidos indicaram fitotoxicidade do LCC e da formulação para as espécies testadas.

“…Copaíba continues to be an object of medical research for its potential antibiotic, antiinflammatory, antirheumatic, and antitumor properties (Plowden 2004;Veiga Júnior and Pinto 2002). Recent research examines larvicidal activity of copaíba against the Aedes aegypti mosquito, responsible for transmission of dengue fever, yellow fever, and the Zika virus (Mendonça et al 2005), while other studies focus on the oil's potential use in treating cutaneous lesions caused by leishmaniasis (Oliveira dos Santos et al 2011). Copaíba oil has also been identified as a potential biofuel, which has stimulated studies on factors affecting oil productivity (Newton et al 2011), optimal harvest cycles (Klauberg et al 2014), and sustainable harvesting methods (Medeiros and Vieira 2008).…”

The Mind of the Copaíba Tree: Notes on Extractivism, Animism, and Ontology from Southern Bahia

This article analyzes ritualized prescriptions for harvesting oleoresin or “oil” from the copaíba tree in Brazil. These harvesting prescriptions involve increasingly complex attributions of mind to the copaíba tree itself. The copaíba tree is widespread throughout the Americas, and for centuries has been well-known for the medicinal oil that can be extracted from its trunk. In Brazil, contemporary knowledge of the copaíba tree is bound up with colonial history and what were often destructive extractivist economies. Whereas historical accounts of the copaíba tree are often limited to mechanistic descriptions for extracting oil, this article examines attributions of mind that harvesters make to the copaíba tree. These attributions can be read from procedures for extracting oil. Such procedures are concerned with moon cycles, tree marking, sexual activity, and gaze. The article shows that such prescriptions have a wide transregional and interethnic distribution, from the Amazon Basin in northern Brazil to the Atlantic Forest on Bahia’s southern coast. New evidence from southern Bahia also involves prescriptions concerning speech and naming, which presuppose that the copaíba tree is sensitive to intentionality and human language. These mind attributions are inferred through pragmatic analysis of the (ontological) presuppositions that are embedded by harvesting prescriptions. The contribution concludes with reflections on the implications of this presuppositional analytic approach for debates concerned with animism and the “ontological turn.”

ABSTRACT:The aim of this study was to assess the chemical composition of essential oils of Illicum verum, Ageratum conyzoides, Piper hispidinervum and Ocotea odorífera, as well as their toxicity to the green-aphid Schizaphis graminum. Compound identification was carried out with gas chromatography + mass spectrometry, and quantification with gas chromatography + flame ionization detector, both with DB5 column. The hydrodistillation process promoted oil yield of 3.81% for I. verum; 0.46% for A. conyzoides; 2.85 % for P. hispidinervum; and 0.68 % for O. odorífera. The major components from the oils of A. conyzoides was precocene (87.0%) and (E)-caryophyllene (7.1%); (E)-anethol (90.4%), limonene (2.6%) and methyl-chavicol (1.3%) for I. verum; methyleugenol (81.2%) and safrole (10.6%) for O. odorifera; and safrole (82.5%) and α-terpinolene (13.4%) for P. hispidinervum. The acute toxicity test (24 hours) performed by contact in sorghum leaves or contaminated filter-paper showed that the higher toxicity occur with essential oils of A. conyzoides, with LC 50 of 7.01 and 7.01 µg oil/cm 2 , respectively; followed by O. odorifera, with LC 50 of 17.10 and 66.70 µg oil/cm 2 , respectively; I. verum, with LC 50 of 66.40 and 65.40 µg oil/cm 2 , respectively; and low toxicity was observed for the P. hispidinervum essential oil, with LC 50 of 64.00 and 143.00 oil/cm 2 , respectively. With the results obtained in this research, we can state that the use of these essential oils can be a new tool in integrated pest management.
