The biology of the species of white grubs was studied in Khed Taluka with both laboratory as well as field experiments were carried out from 2011 and 2013. The occurrence of white grub species found in Khed Taluka was surveyed; we found the two major scarab species that are Holotrichia serrata (Fab.) and Holotrichia fissa (Bre.). The Holotrichia serrata (Fab.) was most dominant species found in Khed Taluka, there was distributed in Wada and Pait regions than Khed and Chakan regions. The Holotrichia serrata (Fab.) beetles were collected from host plant neem, Azadirachta indica and acacia, Acacia arabica, especially neem and Holotrichia fissa (Bre.) were collected from ber, Zizyphus ssp., neem, Azadirachta indica, babhul, Acacia arabica and khair, Acacia catechu, especially ber, Zizyphus ssp. The laboratory, the evaluation of external morphology of scarab species shows Holotrichia serrata (Fab). Adults of Holotrichia serrata (Fab) are reddish brown in colour, compact and medium sized with three pairs of legs. The ventral side is shining, labium and labrum is bristly. An antenna is lamellate type. Tibial spurs are distinguished characteristics of male and female adult identification.%%%References p. 169-200
