“…Direct toxicity of EOs is a consequence of neurotoxic action through acetylcholine esterase inhibition or interference with receptors of octopamine and GABA neurotransmitters, while indirect toxicity is related to numerous biochemical and physiological targets [ 47 ]. EOs may act as insect growth regulators [ 48 , 49 ], disrupt gut epithelium structure [ 50 ] or inhibit digestive [ 51 ] and detoxification enzymes [ 52 , 53 , 54 , 55 ]. At the cellular level, essential oils and their components may exert prooxidant effects by changes in electron flow through mitochondrial complexes and increasing reactive oxygen species (ROS) production which cause damages to macromolecules and apoptosis [ 56 ].…”

The bean weevil Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae: Bruchinae) can cause significant losses in production of its primary host common bean Phaseolus vulgaris L. To avoid bean protection with environmentally risky chemical insecticides and provide sustainable and safe production of food, new pest management methods based on natural compounds are investigated. In the present study, we evaluated protective potential of the essential oil (EO) from the common thyme Thymus vulgaris L. applied on bean seeds. We assessed residual contact toxicity of thyme EO and its effects on A. obtectus longevity, oviposition and adult emergence. Furthermore, to elucidate the role of oxidative stress in thyme EO toxicity, we estimated the levels of oxidatively damaged proteins and lipids, as well as the level of thiols which have important role for antioxidant capacity. We found that thyme oil significantly reduced adult survival and longevity, induced oxidative damage to lipids and proteins and depleted protein and non-protein thiols in a concentration-dependent manner. Females appeared to be more tolerant to thyme oil treatment than males. Sublethal EO concentrations affected oxidative stress indices, deterred oviposition and strongly inhibited adult emergence. The results suggest that thyme oil has the potential to be used as an ecofriendly insecticide for A. obtectus control.

The sand fly, Phlebotomus papatasi (Scopoli, 1786) (Diptera: Psychodidae), is the main vector of Leishmania major Yakimoff and Schokhor, 1914, the causative agent of zoonotic cutaneous leishmaniasis North Africa, the Middle East, and North Sinai. The purpose of this study was to determine the effect of fungi on P. papatasi larvae, pupae, and adults using light microscopic analysis, scanning electron microscope (SEM), and histopathological studies. Specifically, larvae, pupae, and adult P. papatasi were infected with the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae. Scanning electron microscope and histopathological methods were used to investigate the destructive impact of the fungi on the external and internal structures of P. papatasi. The results revealed propagation of the conidia on the cuticles of all P. papatasi life stages, including on the compound eyes, leg setae, thorax, wings, and abdomen of the adults. Histological sections of the control and treated larvae, pupae, and adults showed many alterations and malformations in the body and tissues of all life stages after 72 h. These results demonstrated that B. bassiana was more effective than M. anisopliae as a biological control of phlebotomine sand flies. Further studies to determine the best methods for delivery and application in the diverse ecological settings of the various leishmaniasis vectors are recommended.
