The use of pesticides plays a vital role in agriculture for protecting crops from pests and diseases. However, conventional delivery methods have drawbacks including toxicity, lack of efficiency, and negative environmental impacts. Nanotechnology offers solutions through nano-enabled smart pesticide delivery systems. These utilize nanoparticles as carriers that can encapsulate, absorb, or bind pesticides. Nanoparticles like liposomes, polymer nanoparticles, dendrimers, nanoemulsions, and nanocapsules allow for targeted and controlled release directly onto crops and pests. This improves pesticide efficacy while reducing toxicity and leakage into soil and water systems. Additional functionalization of nanoparticles can also improve targeting, uptake, and controlled environmental release. Examples include using ligands for binding to plant surfaces and pH-responsive nanoparticles that release pesticides following uptake by pests. The use of nanotechnology allows minimal use of pesticides, reducing environmental contamination and exposure risks. Challenges remain such as higher costs,Scaling up fabrication, assessing ecological impacts, and lack of standardized regulations. Further research and development of nano-enabled pesticide delivery can pave the way for next-generation crop protection solutions.

This study delves into the intricate realms of Brevicoryne brassicae (L.), commonly known as the cabbage aphid, shedding light on its biology, diversity, distribution, and characterization within cabbage ecosystems. Through a comprehensive examination of these facets, we aim to unravel key insights into the life cycle, morphological variations, and geographical presence of B. brassicae, offering a nuanced understanding of its ecological significance. Utilizing a combination of field surveys, laboratory experiments, and molecular analyses, we assess the diversity of B. brassicae populations and their potential impact on cabbage crops. The study provides valuable information for pest management strategies and contributes to the broader understanding of insect-plant interactions in agricultural ecosystems.

Stored product insect pests pose a significant threat to global food security and economic stability, as they cause substantial damage to stored grains and other food commodities. Traditional pest control methods often rely on chemical insecticides, which can have adverse effects on the environment, human health, and food safety. In light of these concerns, there is growing interest in exploring sustainable and eco-friendly alternatives for managing stored product insect pests. This abstract highlights the potential of plant-based products as a viable and environmentally friendly approach to control stored product insect pests. Plant-based products, such as botanical extracts and essential oils, are derived from various plant sources and have shown promise in repelling, deterring, and even killing insect pests. These products offer several advantages, including biodegradability, reduced chemical residues, and minimal harm to non-target organisms. This review summarizes recent research on the efficacy of plant-based products against a range of stored product insect pests, including but not limited to beetles, weevils, and moths. It discusses the mechanisms through which these products exert their pest control effects, such as disrupting insect behavior, affecting their reproduction, or inducing mortality. Moreover, the potential synergistic effects of combining plant-based products with other pest management strategies, like hermetic storage and modified atmospheres, are explored. In addition, this abstract examines the challenges and limitations associated with the use of plant-based products in pest management, including issues related to formulation, stability, and the need for further research to standardize application protocols. The economic feasibility and scalability of plant-based pest control methods are also considered. The findings presented in this abstract emphasize the importance of incorporating plant-based products into integrated pest management strategies for stored product insect pests. These products have the potential to contribute to a more sustainable and environmentally friendly approach to safeguarding global food reserves, while minimizing the risks associated with chemical pesticides. Further research and collaboration between the scientific community, agricultural industry, and policymakers are essential to harness the full potential of plant-based products in the fight against stored product insect pests.

The RNA interference (RNAi) has emerged as a promising approach for targeted and eco-friendly insect pest management in sustainable agriculture. The RNAi involves the silencing of specific genes through the introduction of double-stranded RNA (dsRNA), leading to the degradation of complementary mRNA and subsequent reduction in the expression of targeted proteins. This chapter provides a comprehensive overview of the current state and future prospects of RNAi-based strategies for insect pest control. We discuss the molecular mechanisms underlying RNAi, delivery methods for dsRNA, and the design and selection of effective target genes. The application of RNAi in controlling various insect pests, including lepidopterans, coleopterans, and hemipterans is extensively reviewed. also highlight the potential challenges and limitations associated with RNAi-based pest management, such as off-target effects, variable efficacy across insect species, and the development of resistance. Strategies to overcome these challenges, including the use of nanoparticle-based delivery systems and the combination of RNAi with other pest control methods, are explored. Furthermore, discuss the environmental and ecological considerations surrounding the use of RNAi in agriculture, emphasizing the importance of assessing non-target effects and the need for appropriate risk assessment frameworks. The chapter concludes by outlining future research directions and the potential for RNAi to revolutionize insect pest management, contributing to the development of sustainable and resilient agricultural systems.
