ABSTRACT
Insects, integral to Earth's ecosystems, play multifaceted roles that underpin environmental balance and human survival. Spanning roles from pollination to decomposition, these organisms also intersect with socio-economic, cultural, and public health sectors. This review delves into the diverse spheres of insect interactions within ecosystems, from their evolutionary histories to their roles as both predators and prey. The paper sheds light on the intricate predator-prey dynamics, emphasizing insects' roles in pest control and as pivotal food sources for various taxa. The significance of insects in soil ecosystems is elaborated upon, highlighting their contribution to soil health, nutrient cycling, and plant growth. With the looming threats of climate change, habitat destruction, and pollution, insects face unprecedented challenges, which in turn can have cascading effects on ecosystems. In the realm of public health, the review underscores the role of insects as disease vectors, necessitating a balanced approach to ecosystem health and disease management. As vectors, they also catalyze the spread of diseases, creating an intricate balance between maintaining biodiversity and safeguarding human health. The review also touches upon the cultural and economic contributions of insects, from traditional medicine to their utilization in contemporary diets, demonstrating their deep-rooted ties with human societies. With burgeoning technological advancements, the research landscape in entomology is undergoing a seismic shift. Embracing tools such as molecular studies, drones, and AI, the field is poised for groundbreaking insights. As the review suggests, the path forward demands an interdisciplinary approach, amalgamating knowledge from varied scientific domains to grasp the complexities of insect behaviors and interactions fully. In conclusion, insects, though diminutive in size, cast a vast shadow on our planet's functioning. Understanding their roles, challenges, and potential can pave the way for sustainable futures, balancing ecological health with human progress.
ABSTRACT
Agrochemicals, including fertilizers, pesticides, and herbicides, are widely used in agriculture to improve crop yields and protect plants from pests and diseases. There is growing concern over their impact on beneficial soil microorganisms and, indirectly, on human health. This review aims to provide an in-depth analysis of the effects of agrochemicals on soil microbial communities and human health, focusing on recent scientific research and case studies. Exploring various agrochemicals can disrupt microbial diversity, population, and functionality, affecting crucial soil processes and, in turn, ecosystem health. We delve into the pathways of human exposure to agrochemicals and the potential health implications. To mitigate the adverse effects of agrochemicals, the review highlights several alternative approaches, including the use of organic fertilizers and pesticides, precision agriculture, and genetically modified crops. Despite these advancements, research gaps persist in understanding the complex interplay between agrochemicals, beneficial microorganisms, and human health, particularly in the changing agricultural practices and climate conditions. We argue that interdisciplinary, long-term studies are needed to fill these gaps and develop sustainable, health-conscious agricultural practices. The review is intended for researchers, policymakers, and agricultural practitioners seeking to understand and address the environmental and health impacts of agrochemicals.
