Effect of pesticide use in the crop fields is now well known. Tea is no exception to this. Idea behind the present discourse is to appreciate the biological potential of spiders in tea ecosystem. As a first step towards biological control attempt has been made to evaluate the spiders present in tea ecosystem irrespective of the use of pesticides. The monograph deals with the taxonomy, distribution, seasonal incidence, etc. of spiders that would ultimately reflect the occurrence of tolerance/susceptible species. The generated data helped proposing a management plan. It is believed the monograph may come out as a primary source for a better IPM.
