“…This organ section is a region of digestion and absorption of nutrients modulated by the gut microbiota, housing one of the main defense mechanisms against pathogenic microorganisms [37]. Accordingly, the midgut is a target for biologically active chemicals, as it has been published for plantderived molecules [38]. In fact, it has been reported that the midgut may be the site where most oral insecticide penetration occurs [39].…”

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.

“…Changes in the locomotion of T. molitor caused by OEO may be due to the toxic effect of this EO on the nervous system. Altered behavioral responses have been observed in different insects after toxic compounds exposure [22,29,58] with direct consequences on the orientation and olfactory response [59][60][61]. In T. molitor, larvae and adults exposed to contaminated surfaces by OEO gradually increase the distance walked, velocity, and reduce the resting time, indicating repellency.…”

“…EOs are a mixture of plant metabolites (monoterpenes, phenylpropenes, and sesquiterpenes) and act on the nervous system of insects, affect acetylcholine [17], γ-aminobutyric acid [18], and octopaminergic receptors [19], as well as respiratory pathways [20]. For instance, EOs can be applied on insects by contact (through the integumentary system) [14], inhalation (through the respiration system) [21], and orally (through the digestive system) [22]. The biological activity on insects caused by EOs varies according to plant species, and their efficacy has been demonstrated in coleopteran stored product pests [12,15,23].…”

Tenebrio molitor is one of the main stored product pests. This study characterized oregano essential oil (OEO) by gas chromatography (GC/FID and GC/MS) and assessed its insecticidal properties against T. molitor. Mortality, survival, respiration, and behavioral response in larva, pupa, and adult of this insect were determined. The major components of OEO were carvacrol (25.6%), p-cymene (12.3%), linalool (8.71%), thymol (7.22%), γ-terpinene (7.21%), caryophyllene oxide (4.67%), α-pinene (2.71%), and eucalyptol (2.69%). OEO caused high contact toxicity in larvae (LD50 = 3.03 µg insect–1), pupae (LD50 = 5.01 µg insect–1), and adults (LD50 = 5.12 µg insect−1) of T. molitor. Survival rates were 100% in larvae, pupae, and adults of T. molitor not treated with OEO, declining to 65–54%, 38–44%, 30–23%, and 6–2% in insects treated with LD25, LD50, LD75, and LD90, respectively. Low respiration rates of T. molitor at different developmental stages was observed after OEO exposure. Additionally, OEO exposure affects behavioral avoidance response and causes repellency in larvae and adults. These findings show that OEO exerts insecticidal and repellent effects against T. molitor, suggesting a potent alternative to synthetic insecticides for controlling the beetle.

Leafcutter ants are one of the most destructive and economically important herbivores in both forest and agricultural crops, due to their abundance and wide distribution. The most used method for controlling this pest is still through synthetic formicides, due to their high efficiency. However, essential oils represent an alternative, as they are biodegradable and selective and have a toxic effect on a wide range of organisms, including leafcutter ants. The combination of insecticidal activity of a product and possible fungicidal activity constitutes an effective strategy against these insect pests, since both agents of this mutualistic interaction (both organisms are benefited) are affected, ensuring quicker collapse of the colony. The aim of this study was to evaluate the insecticidal and fungicidal activity of Cymbopogon citratus essential oil applied on Atta sexdens colonies under laboratory conditions. A nebulized spray system with three concentrations (15, 30 and 60%) and a control treatment were used to evaluate the effect of C. citratus on A. sexdens colonies. The C. citratus essential oils showed both insecticidal activity against the leafcutter ants (A. sexdens) and fungicidal activity against their symbiotic fungi. Colonies exposed to this essential oil showed considerable reduction in the weight of fungal mass, and mortality of both the queen and worker ants, which proves to be promising for the development of new insecticides for management of this insect pest.
