Insect Population Dynamics and Order-wise Diversity in Agroecosystems

Abstract

Agricultural ecosystems support a wide range of insect populations that play crucial roles in ecosystem functioning, crop productivity, and ecological balance. Insects belonging to different taxonomic orders contribute as pollinators, predators, decomposers, and pests, thereby influencing both beneficial and harmful processes within agroecosystems. High insect population levels in agricultural fields are often associated with favorable environmental conditions, crop diversity, and availability of resources, but may also indicate pest outbreaks under intensive farming systems. The present study examines insect population levels and the diversity of major insect orders in agroecosystems, emphasizing their relative abundance, functional roles, and ecological significance. Order-wise analysis revealed dominance of Coleoptera, Lepidoptera, Hymenoptera, and Hemiptera across different crop types. The study highlights how crop type, seasonality, and agricultural practices influence insect population structure. Understanding insect population dynamics and taxonomic diversity is essential for ecosystem monitoring, biodiversity conservation, and development of sustainable pest management strategies in agricultural landscapes.
