Background/Objectives: This study aimed to develop gel nanoemulsions (NEs) of Brazilian essential oils (EOs) from Eugenia uniflora and Psidium guajava, as well perform chemical characterization investigate the antimicrobial activity EOs NEs. Results/Conclusions: The main compounds E. EO were curzerene (34.80%) germacrene B (11.92%), while those P. guajava β-caryophyllene (25.92%), β-selinene (22.64%), γ-selinene (19.13%). NEs had droplet sizes 105.30 99.50 nm polydispersity index (PDI)...
The diamondback moth (Plutella xylostella) is a cosmopolitan pest known for its destruction of cruciferous plants. Commercial insecticides, such as Decis 25 EC and Azamax, are the main forms controlling this in irrigated systems agricultural communities city Garanhuns (northeastern Brazil). However, difficulty resides high fecundity short lifecycle, which serve resistance mechanisms to insecticides. Considering immediate need find alternative products insecticides employed these communities,...
The aim of the present study was to evaluate insecticidal effects hexane and ethanolic extracts flowers fruits Muntingia calabura against diamondback moth, Plutella xylostella. leaf disc immersion methodology carried out assess on larvae pupae as well duration larval phase following feeding first instar treated discs for 72 h. All were toxic P. M. most xylostella with LC50 values 0.61 μg mL−1 1.63 respectively, followed by extract (LC50 = 5.5 mL−1) 18.9 mL−1). more compared cordycepin,...
Abstract A longstanding paradigm in ecology is that there are positive associations between herbivore diversity, specialization, and plant species with a focus on taxonomic diversity. However, phytochemical diversity also an informative metric, as insect herbivores interact host plants not entities, but sources of nutrients, primary metabolites, mixtures attractant repellant chemicals. The present research examines responses to measured volatile similarity the tropical genus Piper . We...
Abstract Species richness in tropical forests is correlated with other dimensions of diversity, including the diversity plant–herbivore interactions and phytochemical that influences those interactions. Understanding complexity plant chemistry importance for plant–insect overall forest has been enhanced significantly by application metabolomics to natural systems. The present work used proton nuclear magnetic resonance spectroscopy ( 1 H‐NMR) profiling crude leaf extracts study similarity...
Leaf and fruit essential oils of Eugenia langsdorffii were analyzed by GC-FID (gas chromatography with flame ionization detection) GC-MS mass spectrometric detection), featuring a high percentage sesquiterpenes. epi-Longipinanol (13.6 ± 0.1%) γ-eudesmol (12.3 0.2%) the principal components leaf oil, whereas 10-epi-γ-eudesmol (35.7 0.3%) 1,10-di-epi-cubennol (15.6 major constituents oil. A comparative study to assess fumigant residual contact toxicities was conducted. The oil (lethal...
Abstract Tetranychus urticae is a major agricultural pest with worldwide distribution that has caused considerable damage to vegetable crops in north‐eastern Brazil. The aim of the present study was investigate chemical and lethal/sublethal effects essential oils from peels lime ( Citrus aurantiifolia ), lemon C. limon mandarin orange reticulata ) × sinensis as well selected constituents (linalool, α ‐terpineol, ‐pinene, β terpinolene limonene) against T. . greatest yield achieved tangerine...
The repellency and fumigant toxicities of the peel essential oils Citrus sinensis var. pêra (LP), C. mimo (LM), aurantium (LL) cultivated in northeast Brazil were evaluated against Tetranychus urticae. Analysis by GC GC/MS led to identification twenty-eight components, which represented 99.9%, 99.7% 99.3% total constituents LP, LM LL oils, respectively. Limonene was main component found all three oils. Other components alpha-pinene (1.5% LP; 1.4% LM), myrcene (5.7% 5.9% 5.6% LL) linalool...
The essential oils from Mangifera indica var. Rosa and Espada latex were obtained by hydrodistillation analyzed using GC-FID GC-MS. Twenty-seven components identified. main compound in the oil M. (EOMiE) was terpinolene (73.6%). of (EOMiR) characterized high amounts β -pinene (40.7%) (28.3%). In test for leishmanicidal activity against promastigotes forms L. amazonensis , EOMiR EOMiE showed IC 50 (72 h) 39.1 23.0 μ g/mL, respectively. macrophages, CC 142.84 158.65 However, both more specific...
Essential oils from the leaves of two species genus Ocotea that occur in Atlantic Forest state Pernambuco, Brazil, were analyzed using gas chromatography-mass spectrometry. The acaricidal activity these as well 11 selected components and blends evaluated fumigation residual contact tests against two-spotted spider mite (Tetranychus urticae). Sixty-seven constituents identified, totaling 97.3 ± 0.3% 97.8 0.5% O. duckei glomerata, respectively. Sesquiterpene was dominant class. compounds...
The compositions of the essential oils from unripe (UFr) and ripe (RFr) fruits Schinus terebinthifolius were analyzed by GC GC/MS. major compound identified in both was limonene (UFr = 44.1 +/- 1.3%; RFr 31.8 1.2%), followed alpha-phellandrene (15.7 0.4%) UFr oil thujene (21.7 0.9%) oil. Repellent toxicity activities two also evaluated, results compared with eugenol. more active fumigation tests (LC50 1.46 microL/L air), whereas sealed dishes (SD) than open (OD) contact assay 3.04...
This study aimed to evaluate the efficacy of Corymbia citriodora, Melaleuca alternifolia (Myrtaceae), Mentha × piperita (Lamiaceae), and Schinus terebinthifolius (Anacardiaceae) essential oils as an alternative manage Sitophilus zeamais (Coleoptera: Curculionidae) adults.Acute contact toxicity, acute toxicity on treated maize grain, fumigation repellency bioassays, GC-MS analysis were carried out.Corymbia M. alternifolia, piperita, S. toxic at different levels through residual contact,...

Seventy constituents identified by gas chromatography-mass spectrometry (GC-MS) municipalities Serra Talhada (ST), Buíque (BU) Floresta (FL), representing 97.99±1.03% 97.12±0.94% leaf stem ST, 97.42±0.77% 97.50±0.68% BU 98.30±0.84% 97.10±0.80% FL. Sesquiterpenes predominant oils. β-caryophyllene was main constituent all...
Essential oils from the leaves of Bauhinia rufa and B. dumosa collected Cerrado biome in central Brazil were obtained by hydrodistillation analyzed using GC GC/MS. Both had a predominance sesquiterpenes (B. rufa: 95.3 ± 0.5%; dumosa: 97.2 1.1%). β-Caryophyllene (15.8 0.5%), epi-α-cadinol (12.8 0.4%), γ-muurolene (12.2 0.4%) α-cadinol (10.0 0.5%) identified as major constituents oil, whereas germacrene B (37.6 1.2%) (E)-nerolidol (29.1 0.6%) oil. toxic to Tetranychus urticae fumigation LC50 =...
