For effective management and Judicial use of the earth's resources Knowledge of biodiversity is important. In the Animal Kingdom terrestrial arthropods are the most diverse groups, and important contributors to biodiversity. Insects and their relatives are critical components of terrestrial ecosystems and are often considered ecosystem engineers. Arthropods play crucial role in the evolution of biotic community and its maintenance. They act as pollinators of flowering plants, consumers and recyclers for decomposing organic materials, and they are the important part of food chains and food webs of vertebrates and invertebrates. They provide enormous ecosystem services. For the study of arthropod diversity statistically valid samples can be captured in short durations. The insects have been used as indicators of restoration success and ecosystem functionality because they respond to environmental change rapidly. A large number of methods are available for the collection and sampling of arthropods residing in different habitats. The efficiency and effectiveness of these methods varies as per location. This study deals with active and passive sampling methods and offers general guidelines for planning a study of arthropod biodiversity. it includes attention to long-term planning as per the choice of taxonomic groups, and the sampling resources required for sorting and identification. A general index must include, at a minimum, Malaise, flight-intercept and pan traps, aerial netting, aspirators as well as behavioural extractors such as Berlese funnels.
