Natural history collection is considered one of the important tools for the study of biodiversity of a country. Properly identified and classified specimens with complete data such as locality, date of collection and other related remarks, act as a time machine and provide information on the status, abundance and a distribution of a particular species or a group in the past. This information is vital to plan proper conservation measures for the survival of a species or a group in the present and future.
Man originated about a million years ago and insects at least 500 million years ago. Insects constitute the largest class of the living organisms and about 72 per cent of all living animals are insects with approximately 1-1.5 million known species. Insects are omnipresent and each crop we cultivate is being attacked by at least a dozen of insect species.
