Growth and development of Spodoptera litura and Spilarctia obliqua was drastically suppressed by diflubenzuron. No larvae of Spodoptera litura could reach up to pupation in case of 0-24 hrs old larvae at 125 and 250 ppm and 6 day old larvae at 250 ppm of diflubenzuron. While for S. obliqua, it was true for 0-24 hrs old larvae at 62.5, 125 and 250 ppm and for 8 day old larvae at 250 ppm level of diflubenzuron. Further, 24 hrs old larvae were more susceptible than older ones.
