The beneficial insects constitute a significant component of the organization and the operation of agro systems in regard to their pest control function, improvement of pollination, and their involvement in nutrient circulation and soil wellness. Such organisms include predators, parasitoids, pollinators, and decomposers, which belong to complex trophic networks which promote the equilibrium of the ecosystem and the agricultural output. Although modern day agriculture has been more inclined towards adopting chemical control practices, recent developments involving environmental degradation, biodiversity and food security loss have seen a shift in focus towards exploiting the useful insect communities in relation to integrated pest management (IPM) techniques. The paper addresses the ecological services of useful insects, how such are helpful in the delivery of agro ecosystem services, and the issues involved in conserving and enhancing useful insects in highly-managed agricultural environments. The synthesis brings out the importance of managing the habitat, reduced reliance on pesticides, and landscape diversity in order to maximize the benefits of useful insects to sustainable crop production.
