Indian Scenario of Cotton Hybrid Technology, Reseach Projects & Recommendations

            da, were caught in the pheromone
            traps set up for Spodoptera litura.
            It is an indication that S. frugiperda
            is fast spreading. Even though cot-
            ton is not a preferred host of this
            pest at present, a vigil should be
            kept on its incidence at all centres
            as a proactive measure in view of
            the fact that certain pests are
            known to change their host prefer-
            ences over a period of time.
