Abstract : Biodiversity in the recent years has been variously defined, understood and interpreted but seldom with holistic approach. The environment being a part of the great biosphere in combination with varieties of flora and fauna plays pivotal role in the formation of holistic concept of biodiversity. Socio economic and aesthetic approach of dealing biodiversity is one of the important contemporary dimensions which may further create the functional model or paradigms for understanding the environmental role of this component.
Biodiversity of predaceous coccinellids representing the lady bugs and their role as bioindicators in agro-ecosystem has pioneering role in the development of strategies for biological pest control having immense practical and scientific interest. The species of lady bugs- Coccinella septumpunctata, Epilachna vigintioctopunctata and Rodolia amabilis found in agro ecosystem in terms of biodiversity can be recruited as bioindicators due to their climatic and trophic characteristics. These beetles were abundantly found and sampled from two types of agro ecosystem of Ranchi crop & forest area. The statistical computations of sampled data of the bugs have been found to be of significant value as bioindicator pronouncing the role in socioeconomic and aesthetic paradigms. These profiles of biodiversity are judging parameters of socio economic conditions of farmers along with the attractive and beautiful aesthetic scenario created by the colorful beetles wriggling on the leaves of the host plants.
