Abstract
This study was carried out in order to know the biodiversity of staphylinid species due to their multi-dimensional behavior;
i.e. predators, parasites, pollinators, decomposers and scavengers in the ecosystem. For this purpose, collection was made
from cropped area (8 localities) of the Punjab, Pakistan with 5 different collecting methods; pitfall trapping, flight intercept
trapping, light trapping, Burleson’s funnel trapping and sweep netting during 2008. Population was recorded for four days
after every two months from each locality during the entire collection period. Eight hundred and seventy four (874)
specimens were collected and identified up to species level (26 species) belonging to 15 genera and 5 subfamilies. Paederus
fuscipes was the species with highest overall population (33.6%) while Tachyporus himalayicus was with lowest population
(0.5%). High α-diversity index (20.804) and Shannon weaver index value (2.572) was found from Sargodha and Rahim Yar
Khan and their lowest values (9.76) and (1.82) respectively were found from Rawalpindi during 2008.
