Abstract: The present study was conducted at research farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur during kharif season 2013-14 under upland transplanted rice ecosystems (UDS). The results of field experiments revealed that the maximum population of rice stink bugobserved on 42 SMW in month of October with 18.75 nymph/adult/25 sweeps. The seasonal mean population of bug was 3.09 nymph/adult/25 sweeps. The rice stink bug showed non-significant positive correlation with sun shine hours and non-significant negative correlation with maximum, minimum and average temperature, morning, evening and Average relative humidity at 5 and 1 per cent level of significance.
Key words: Ecosystem, Rice stink bug, Upland, Wealth
