Walnut yield and quality are often affected by beetle infestations, particularly those caused by Carpophilus dimidiatus (Fabricius) (Nitidulidae) and Oryzaephilus mercator (L.) (Silvanidae). Beetle damage exposes walnut to microbial food spoilers such as Fusarium species. Insecticides currently used for beetle control are environmentally unfriendly. Pest-suppressing nanomaterials can generate innovative nanopesticide technologies leading to more sustainable and efficient farming practices. This work explores a green synthesis approach for copper oxide nanoparticles (CuO-NPs) in basic medium by hydrolates obtained from Lippia integrifolia and Pimpinella anisum, denoted as CuO-I and CuO-A, respectively. Characterization through XRD, FT-IR, Raman, UV-Visible absorbance, and AFM techniques, indicated that CuO-A and CuO-I have a size ranging 2-10 nm height. Antifungal assay showed that both have a similar efficacy (MID = 320 µg), 3-fold stronger than CuO- NPs obtained in absence of hydrolates (denotes CuO-W) (MID = 960 µg), with the broadest inhibitory halos (ID = 126-128 mm) observed for CuO-A. Insecticidal activity of CuO-NPs showed a concentration-dependent behavior, with CuO-I showing an effect comparable to diatomaceous earth. SEM images confirm the adhesion of nanoparticles to insect surfaces, which could induce oxygen deprivation and disrupting of metabolic processes. Both CuO-A and CuO-I are promising for their use in integrated pest control in walnut storage.

“…Although there is a growing demand for these products (Alighiri et al, 2017), the yield of essential oil in many plant species is low. This results in a large volume of residues during the distillation process (Napoli et al, 2020). On an industrial scale, the waste that is accumulated in the distilleries of essential oils can be compared to the volume of waste that is produced by the textile industry (Gharred et al, 2020).…”

On an industrial scale, the residues accumulated in essential oil distilleries can be compared to the volume of residues produced in a textile industry. Although these residues are discarded, they possess molecules with diverse biological activities, including their application in phytopathogen control. In this study, the chemical profile of the residue from the hydrodistillation of Lantana camara L. leaves was determined using High-Performance Liquid Chromatography (HPLC). Additionally, the effect of the residue on cells was assessed by determining plasma membrane integrity, levels of reactive oxygen species (ROS) production, and mitochondrial potential depolarization. The viability and cell density of Phytomonas serpens parasites significantly decreased after treatment with increasing concentrations of the lyophilized residue. RL038, the lyophilized residue from accession LAC-038, reduced cell viability by an average of 61.36%. ROS levels increased by approximately 2x and 3x at RL038 concentrations of 120 µg/mL and 180 µg/mL, respectively. It was observed that the same concentrations modified mitochondrial potential, reducing fluorescence by 44.6% and 46.8%, respectively. Analytical liquid chromatography of RL038 revealed the presence of 17 peaks subsequently classified as phenolic acids and flavonoids. RL038 from the hydrodistillation of Lantana camara L. leaves is a source of biologically active compounds with antiprotozoal potential.
