Abstract

The present study evaluates the activity of white stem borer, Scirpophaga fusciflua on rice in Kangra valley deploying light trap and sweep net. The results revealed that moths were active from 29th to 40th (Standard week) SW and 31st to 40th SW, in 2015–16 and 2016–17, respectively, with the peak activity being at 36th and 37th SW, respectively. The population declined thereafter with nil population subsequently. The weather parameters when correlated with population dynamics revealed a positive relationship with maximum and minimum temperature and relative humidity but a negative one with rainfall.
