Study on ‘ Population dynamics of major insect pests like borers of aonla in relation to abiotic factors was conducted at two locations i.e., Dryland Research Station (DRS), Dhiansar, and RHRSS, Raya i.e., of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu for two consecutive year during. 2016 and 2017. The peak larval population of fruit borer was observed in 36th SW at DRS and 35th SW at RHRSS, Raya viz., 19.75 and 25.75, respectively during 2016. Similarly, fruit borer population dynamics were also observed during 36th and 35th SW during 2017 at DRS, Dhiansar (19.75) and RHRSS, Raya (26.07) locations. The only factor relative humidity (morning) at RHRSS, Raya was found to be positively (0.458*) and significant for increasing the fruit borer population during 2016. While during 2017, maximum temperature had the highly negative significant correlation and relative humidity (morning) and relative humidity (evening) were found to be highly positive significant impact on population build up of fruit borer on both the locations on aonla.
