Impact of Azter (azadirachtin 0.15% EC), a neem-based pesticide, against tea red spider mite, Oligonychus coffeae Neitner (Acarina: Tetranychidae), and its natural enemies
International Journal of Acarology 39 (2), 140-145
Abstract: Azter (azadirachtin 0.15% EC), a neem-based pesticide, was evaluated for acaricidal activity against the red spider mite (RSM) Oligonychus coffeae at three different concentrations (1125, 2250 and 3375 mL/ha) under laboratory and field conditions. All the tested concentrations caused 100% mortality under laboratory conditions. When RSMs were provided with Azter-treated leaves for egg-laying, the numbers of eggs laid were significantly lower than that on untreated control leaves. Application of Azter did not affect the non-target organisms such as Mallada desjardinsi and Oligota pygmaea (natural enemies of RSM). Based on the results obtained from the laboratory studies, a field study was conducted to confirm the acaricidal effect of Azter and the results revealed the potential utility of this neem-based biopesticide as safer for natural enemies in an integrated pest management programme against RSM to minimize the pesticide load in the tea ecosystem.
