“…The effects of EOs on the midgut of insects have also been registered for Cymbopogon winterianus EO on Spodoptera frugiperda [40], causing morphological changes characterized by cytoplasmic protrusions, columnar cell extrusion, and pyknotic nuclei. In addition, Melaleuca alternifolia EO generated an elongation of digestive cells and necrosis on the midgut of Podisus nigrispinus [41], whereas exposure of C. claveri to neem oil induced cell dilation, cytoplasmic protrusions, and cell lysis in the same organ [24].…”

Cymbopogon nardus (citronella) essential oil (EO) has been widely used in the cosmetic and food industry due to its repellent and fumigant properties. The aim of this study was to evaluate its effects on the life cycle and midgut morphology of the natural predator Ceraeochrysa claveri. Larvae were fed on sugarcane borer eggs (Diatraea saccharalis) pretreated with citronella EO solutions (1–100 µg/mL in methanol, 5 s) or solvent and air-dried at room temperature for 30 min. Larval and pupal stage duration, the percentage of emergence of the insect, and malformed insects were recorded. One day after adults emerged from their cocoons, adult insects were used to obtain their midgut and analyzed using light microscopy. The chemical composition of C. nardus EO revealed that citronellal (25.3%), citronellol (17.9%), geraniol (11.6%), elemol (6.5%), δ-cadinone (3.6%), and germacrene D (3.4%) were the predominant compounds. Exposure to the EO produced a significant change in development duration for third instar and prepupa of the insect. The observed alterations in the lifecycle included prepupae with no cocoon formation, dead pupa inside the cocoon, and malformed adults. Several injuries in the midgut epithelium of exposed adults were registered, such as detachment of columnar cells leaving only swollen regenerative cells fixed on the basement membrane, and the formation of epithelial folds. In summary, these data suggest that C. nardus oil has adverse effects on the life cycle and midgut morphology of a beneficial predator.

“…The yield obtained varies according to different parameters, such as the type of plant material, extraction methods, environmental conditions and geographical distribution, among others [31]. On the other hand, the results of the physical properties are similar to studies with other species of the same genus, such as M. alternifolia, which has a density of 0.885 g/mL and a refractive index of 1.482 [17,32,33].…”

A method was developed for the isolation of geranyl acetate from the crude essential oil (EO) of Melaleuca armillaris (Sol. ex Gaertn.) Sm. leaves, and the purity of the isolated compound was analyzed by GC/MS spectral and NMR analysis and was found to have high purity (98.9%). In addition, the EO isolated presented 0.907 g/cm3, 1.474 and [α]D20=−17.6 of density, refraction index and optical rotation, respectively. The chemical composition of the EO obtained for steam distillation from M. armillaris was analyzed by gas chromatographic and spectroscopic techniques (GC/MS and GC/FID). Thirty-eight compounds were identified, representing 99.92% of the total EO analyzed on a DB-5 ms (5% phenylmethylpolysiloxane) capillary column. This analysis showed that the EO consisted mainly of oxygenated monoterpenes (77.01%), followed by monoterpene hydrocarbons (21.31%) and sesquiterpene hydrocarbons (1.31%). Furthermore, the essential oil of M. armillaris was rich in 1,8-cineol (67 ± 2%), followed by limonene (10 ± 1%), α-Terpineol (9 ± 1%) and α-Pinene (5 ± 1%). Finally, the results suggest that the geranyl acetate isolated with high purity from crude essential oil is recommended to be explored as a component in medicinal or industrial use.

El objetivo de este estudio fue comparar los efectos de los pesticidas químicos naturales y sintéticos, examinando la supuesta selectividad de estos compuestos naturales sobre las abejas Apis mellifera. Los valores de LC50 utilizados en los bioensayos se obtuvieron de la investigación de Souza et al. (2023) y son los siguientes: Karate® (13,4 µL/100 mL), compuesto de limoneno (1.440 µL/100 mL) y Roundup® (712.290 µL/100 mL). Sin embargo, según informaron estos autores, se utilizó una concentración de 250 µL/100 mL para Azamax®. Estos valores de LC50, junto con una concentración de 250 µL/100 mL de Azamax®, se emplearon en los análisis inmunohistoquímicos utilizando el método TUNEL y PCNA en el intestino medio de las abejas. También se realizaron evaluaciones inmunológicas (óxido nítrico, fenoloxidasa y marcadores de estrés oxidativo TBARS y GSH) en abejas adultas obreras. Los tratamientos con xenobióticos no revelaron apoptosis o proliferación celular. Sin embargo, observamos degeneración epitelial, marcada por la presencia de células vacuoladas, lo que sugiere un proceso necrótico. Excepto por el compuesto de limoneno, todas las sustancias indujeron estrés oxidativo, lo que llevó a niveles elevados de TBARS. Aunque no hubo diferencias en los niveles de GSH, observamos alteraciones en el sistema inmunológico de estos insectos, caracterizadas por un aumento de la actividad de la fenoloxidasa y los niveles de NO2. Basándonos en los resultados obtenidos, es posible concluir que se debe tener precaución al utilizar pesticidas químicos en la agricultura, ya sean de origen sintético o natural, ya que tienen el potencial de causar daños histopatológicos e inmunológicos irreversibles. Este estudio también subraya la importancia de realizar investigaciones más exhaustivas sobre el impacto de los productos naturales en la fisiología de los insectos polinizadores.
