The objective of study was to examine the population of WBPH and its natural enemies under agro-climatic condition of Haryana, India during Kharif-2012. The WBPH population varied from 0.4 to 403.4/10 hills and 4.6 to 224.4/10 hills during 2011 and 2012, respectively. The maximum population was recorded 38th week during both the years. The population started declining from 39th week and was negligible by the end of October i.e. 42nd and 43rd week during 2011 and 2012, respectively. The population of spiders (39.2/10 hills) and mirid bugs (64.2/10 hills) was maximum in 39th SMW during 2011while in 2012 the population of spiders was maximum (23.6/10 hills) in 37th SMW and that of mirid bugs 66.8 /10 hills in 40th SMW. The correlation of WBPH with abiotic and biotic factors did not show any significant relationship.
