Safety of neem formulations vis-a-vis insecticides to Cyrtorhinus lividipennis Reuter, a predator of brown planthoppers Nilaparvata lugens (Stal) in rice crop



Safety of neem formulations vis-a-vis insecticides to Cyrtorhinus lividipennis Reuter, a predator of brown planthoppers Nilaparvata lugens (Stal) in rice crop



Journal of Biological Control 12(2): 119-122



A greenhouse study was carried out to test the safety of commonly available neem formulations on the mirid bug, C. lividipennis (a predator of N. lugens). The effect of the neem formulations was compared with insecticides recommended for rice (chlorpyrifos and monocrotophos). The neem products tested were Azadirachtin, Econeem, Neem Asal, Neemgold, NG-4, Neemax and Achook. Neemgold at 0.5% and Neemax at 2.0% were safe, causing 26.7 and 33.3 % mortality, respectively, after 72 h exposure.
