Abstract : Statistical information indices being advanced statistical tool for quantifying the species diversity has been established as the indices that can take into account rare species in a community which can be ecologically useful for conservation purposes in habitats wherever they exist. The paper discusses the rationale of use of statistical information indices that diversity of species particularly of lady bird beetles in natural wild and horticultural gardens of Ranchi can be measured in a way that is similar to the information contained in a genetic code which can also be measured through transcription. The SW-diversity value of six species sampled from Zone-II (South-West of Ranchi) during July 2010 to June 2011 as the followup study programme has been quantified alongwith the dominance to the tune of 0.71137 & 4.9326 respectively indicating threatened condition of some species like Hormonia axyridis (Pallas) and Coelophora bissellata (Mulsant).
Key words: Statistical information indices, Rare species, Coccinillid beetles, diversity rationale.
