Seasonal Incidence and Insecticidal Management of Shoot and Fruit Borer (Leuclnodes orbonalls Guenee) in Brinjal

Incidence of fruit borer (Leucinodes orbonalis) In terms of shoot Infestation was observed during 4th week of August, 2008 and the Incidence had non-significant relationship with temperature, relative humidity and rainfall but significant relationship with cocclnellids and spiders. The results of chemical control trial Indicated that Protenfos @ 0.1% and Splnosad @0.01% were most effective In reduction of shoot Infestation of Leucinodes orbonalis besides recording higher brlnjal fruit yield. Among the nine treatments tested, Profendos was the most effective followed by Splnosad individually and their combinations with Novaluran in reducing the population as well as In giving higher yield.
