Abstract:
A field experiment was conducted during
kharif season of 2018 at Agriculture Research Station, Sakoli, Dist. Bhandara (MS) under Dr. Panjabrao Krishi Vidyapeeth, Akola to study the observation of impact of environmental parameters onbrown plant hopper and its natural enemies. The result revealed that abundance of brown plant hopper was initiated from 36
th MW and continued to 47
th MW and its peak incidence during 44
th MW (12.6 nos./hill). Incidence of brown plant hopper had significant negative correlation Rainfall (r= -0.617) and rainy days (r= -671) and maximum temperature (r= 0.597) had significant positive correlation at 5% significant level. Minimum temperature (r= -0.798) showed significant negative significant correlation with population of brown plant hopper at 1% significant level. Similarly, impact of green mirid bug (r= 0.953) and brown mirid bug (r= 0.898) on population of brown plant hopper showed significant positive correlation at 1% significant level.
