Abstract

This review article discusses insects' importance in maintaining ecosystems' equilibrium and productivity. Due to diversity and global distribution, insects contribute to ecological complexity, resilience, and overall health. The article highlights the historical relationship between humans and insects, with insect research becoming a reputable scientific discipline during the Renaissance. The article also discusses the role of insects in pollination, decomposition, and the food web. Insects are crucial for pollination processes, with over 75% of the world's important food commodities relying on insect pollination. Insects also play a vital role in decomposition, transporting organic matter and reintroducing nutrients to the soil. Predatory insects help preserve ecological equilibrium by capturing and ingesting prey, affecting the physical structure of the soil and plant relationships. Soil engineers like termites, dung beetles, and ants contribute to soil ecology by breaking down plant waste and influencing the soil's chemical composition and physical structure. The article also mentions the role of insects as disease vectors and the potential benefits of non-native insect species in ecosystems. In agriculture, insects provide essential ecosystem services such as pollination and pest control, significantly impacting crop yield. Dung beetles, in particular, enhance soil nutrient concentrations and increase crop yield. Overall, the article emphasizes the significant role of insects in maintaining the health and vitality of ecosystems and their importance to human well-being.
