The mites have been reported to develop high levels of resistance to chemicals like TEPP, parathion, malathion, tetradifon and binapacryl etc. They also developed resistance to dicofol, dimethoate, monocrotophos and mevinphos. However, some of the new chemicals like omite and palictran gave better results without harming the predatory fauna of mite pests. Therefore, resistance management involved such mechanisms which extend number of generations that a given pest population might be controlled economically by a pesticide in judicious way. One should evolve such management strategies which extend number of generations that a given pest population can be controlled economically by a pesticide. More over, those approaches should be adopted that kill or at least minimize the fitness of resistant genotypes.
