Monitoring of white stem borer Scirpophaga fusciflua With light trap and sweep net

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 29^th to 40^th (Standard week) SW and 31^st to 40^th SW, in 2015–16 and 2016–17, respectively, with the peak activity being at 36^th and 37^th 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.
