Abstract

A greenhouse study was carried out to test the safety of commonly available neem formulations to the mirid bug, Cyrtorhinus lividipennis Reuter, an effective and widely distributed predator of brown planthopper, compared to that of recommended insecticides in rice. Neemgold at 0.5 per cent and Neemax at 2.0 per cent were safe causing 26.7 and 33.3 per cent mortality, respectively, after 72h exposure; whereas cent per cent mortality was recorded in insecticidal treatments within 24h of exposure.
