INTRODUCTION

Ecosystems serve as the foundation for all human activity. For the ecosystem to function properly and to provide ecosystem services, biological variety must be conserved. Agro ecosystems with high biodiversity levels are more sustainable and profitable for agriculture. A few benefits of agricultural biodiversity include crop pollination, biological crop protection, preservation of soil fertility and structure, defence against erosion, nutrient cycling, and regulation of water flow and distribution. The repercussions of biodiversity loss may not be immediately noticeable, but they could make ecosystems more vulnerable to various abiotic and biotic pressures. One of the challenges of contemporary sustainable agriculture is how to produce food profitably while still preserving biodiversity. Natural selection mechanisms, careful selection, and creative inventions by farmers, herders, and fishers over millennia are what lead to agrobiodiversity. A crucial part of biodiversity is agrobiodiversity. The continued management of numerous biological resources that are vital for food and agriculture is essential for the security of many people's food and livelihoods. Agrobiodiversity, also referred to as the genetic resources for food and agriculture, or agricultural biodiversity, consists of: the types of crops, cattle breeds, fish, and non-domesticated (wild) resources that have been harvested from fields, forests, and rangelands, including items made from trees, wild animals that have been hunted for food, and aquatic ecosystems (such as wild fish); Non-harvested species, such as soil microbiota, pollinators, and other insects including bees, butterflies, earthworms, and greenflies, are found in production ecosystems that support the production of food. Untapped species in the larger Agroecosystems are ecosystems in which people have deliberately selected the biota or the plants and animals that are kept by the farmer as crops and livestock, replacing the native flora and fauna of the area to varying degrees. A modified and simplified plant community that frequently contains foreign species is established and managed, and this affects the composition and activities of the associated herbivore, predator, symbiont, and decomposer sub-communities (Swift and Anderson1993). Agroecosystems may differ from natural ecosystems of the area in many ways, including composition, variety, system structure, and dynamics [1].

All agroecosystems are dynamic and are managed at many levels, causing crop arrangements to change over time and space in response to biological, cultural, socioeconomic, and environmental influences. The degree of spatial and temporal heterogeneity that characterises agricultural regions is determined by such landscape fluctuations, which in turn influences the type of biodiversity present. These changes may or may not be advantageous for the pest protection of specific agroecosystems. Finding the kinds of biodiversity assemblages (either at the field or landscape level) that would provide optimal agricultural outputs is thus one of the key difficulties facing agroecologists today (i.e., pest regulation). The only way to overcome this difficulty is to better examine the connection between vegetation diversification and the population dynamics of herbivores and natural enemies [2].

Crop arrangements fluctuate across time and geography in response to biological, cultural, socioeconomic, and environmental forces since all agroecosystems are dynamic and regulated on many different levels. Such landscape oscillations govern the level of spatial and temporal heterogeneity that characterises agricultural zones, which in turn affects the type of biodiversity present. These modifications may or may not benefit a particular agroecosystem's ability to protect itself from pests. One of the main challenges facing agroecologists nowadays is identifying the kind of biodiversity assemblages (either at the field or landscape level) that would produce the best agricultural yields (i.e., pest regulation). The only way to get beyond this obstacle is to further investigate the relationship between vegetation diversity, the dynamics of herbivore populations, and natural. Due to the fact that all agroecosystems are dynamic and subject to several levels of regulation, crop arrangements change across time and space in response to biological, cultural, socioeconomic, and environmental pressures. These changes in the landscape control the degree of temporal and spatial heterogeneity that distinguishes agricultural zones, which in turn influences the sort of biodiversity that exists. The ability of a given agroecosystem to defend itself against pests may or may not benefit from these modifications. Finding the kind of biodiversity assemblages (either at the field or landscape level) that would result in the optimum agricultural yields is one of the key difficulties facing agroecologists today (i.e., pest regulation). Further research into the connections between vegetation diversity, the dynamics of herbivore populations, and natural processes is necessary to overcome this barrier [3].

The processes of soil formation, structural development (including physical, chemical, and biological aspects of soil), and nutrient cycling mediated by biotic and abiotic variables to support plant growth are all included in soil structure and fertility enhancement services. These soil features play a significant role in determining the amount and quality of agricultural products. The fertility required to support primary production is maintained as soil organisms break down dead organic matter and replace nutrients needed for primary production. Earthworms, centipedes, millipedes, and isopods are examples of macro fauna that aerate soil by creating pores as they burrow through the soil profile, mixing organic and mineral particles, redistributing organic matter and microorganisms, and enriching soil with castings. These macro fauna also mix organic and mineral particles [4,5].
