Special Issue Information

Dear Colleagues,

The use of pesticides is a common way of controlling crop diseases and insects and increasing crop yields. Natural products and their derivatives are important sources of pesticides and play crucial roles in fields such as insecticide production, bactericide development, plant growth regulation, and immune regulation. Due to their diverse sources, structures, and functions, natural products continuously provide new opportunities for pesticide research. Those products have important ecological activities in nature, playing roles as antifeedants, attractants, nematicides, fungicides, repellents, insecticides, insect growth regulators, and allelopathic agents, and can act as promising sources of novel pest control agents or biopesticides. Nowadays, natural products are not only used to confirm known pesticide targets or study their mechanisms of action but also provide a rich library of compounds that can be used to screen functional molecules based on known targets, thereby obtaining the active molecules or frameworks required for the creation of new pesticides.

This Special Issue will focus on the development and application of natural sources pesticides such as plant-derived products, microorganisms, and viruses. Potential topics include, but are not limited to: the discovery of bioactive natural source compounds, innovative synthetic approaches for bioactive nature-inspired compounds, the phytochemical profiling and bioactivity screening of natural products, mechanistic investigations of the activity or resistance of natural products, and the application of natural source products for pest control. Peer-reviewed original research articles and critical reviews will be considered for inclusion.

This study concentrates on assessing the insecticidal attributes of the γ-Al2O3 nanoparticles derived from the remnants of Mentha pulegium, which include essential oil, ethanolic extract, and plant waste. The synthesis of the γ-Al2O3 nanoparticles was executed using a direct sol-gel procedure, affirming the crystal structure according to extensive physicochemical analyses such as UV-Vis, XRD, FTIR, and SEM. Evaluation of the insecticidal activity in vitro was conducted against Xylosandrus crassiusculus, a pest that infests carob wood, utilizing strains from diverse forests in the Khenifra region, situated in the Moroccan Middle Atlas. The lethal doses 50 ranged from 40 mg/g to 68 mg/g, indicating moderate effectiveness compared to the commercial insecticide Permethrin. Optimization of the conditions for the efficiency of the γ-Al2O3 nanoparticles was determined using experimental plans, revealing that time, humidity, and temperature were influential factors in the lethal dose 50 of these nanomaterials. Moreover, this study encompasses the establishment of correlations using Principal Component Analysis (PCA) and Ascending Hierarchical Classification (AHC) among various geographic, biological, and physical data, amalgamating geographic altitude and γ-Al2O3 nanoparticle insecticide parameters, as well as the attributes of the mechanical tests conducted on the carob wood affected by insects. The correlations highlight the close connections between the effectiveness of the insecticide, mountain altitude, and the mechanical parameters that were examined. Ultimately, these nanoparticles demonstrate promising potential as alternative insecticides, thus opening up encouraging prospects for safeguarding against carob wood pests. Full article
