Abstract: Studies on cannibalism of Spodoptera frugiperda in absence of food revealed that, there was no cannibalism in egg stage and 1st instar larval stage. When the same larval instars were allowed for interaction, there was less cannibalism compared to interaction between the different instars of larvae. A high rate of cannibalism was observed in the absence of food. Within 6 hrs of exposure, 68 per cent of cannibalism was recorded in case of 2nd instar larvae compared to 40 and 24 per cent in 3rd instar and 4th instar larvae, respectively. As high as 46 per cent cannibalism was noticed in 4th instar v/s late instar larval treatments within 6 hrs of interaction. The highest cannibalism was registered in case of 2nd instar larvae followed by 3rd instar and 4th instar larval treatments within 6 hrs of exposure. Because of no food condition, the larvae inevitably fed on other instar larvae to survive
