Grasshoppers especially belong to family Acrididae are major role in their respective niches and are significant component in biodiversity model system. They are one of the most important invertebrate groups for environmental monitoring and assessment. Each species has its own reproductive potential to reproduce their offspring in different seasons. The relationship between biodiversity and ecosystem functioning has received increasing scientific interest in recent decades. The dynamic of acridid biodiversity reveals the coupling relationship among abiotic factors, vegetation community and acridid biodiversity in forest ecosystems. This coupling relationship is one of the essential interrelationships in forest ecosystems and it imposes directly on their structure. They are ideal organisms to study effects of climate and agricultural land use on biodiversity.
