BIODIVERSITY OF STAPHYLINIDS IN CROPPED AREA OF THE PUNJAB (PAKISTAN)

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.
