The pesticidal properties of different plants are used worldwide for the control of insect pests of crop plants, and pests of domestic animals and human beings. The seed extract of Hyptis suaveolens contains potential pesticidal components compared to other parts. The potential of Hyptis suaveolens a common weed available in scrub jungles against the larvae of rice moth is tried in this study. Both petrolem ether and ethanolic extracts of H. suaveolens seeds were administered against the larva of the rice moth C. cephalonica stainton either in the form of spray through oral route. The results revealed that administration through oral route was more toxic. LD₅₀ 48h at of 3^rd instar of C. cephalonica was 92.70 μg/g for pet ether and 49.79 μg/g for ethanol. The LC₅₀ values pertaining to spray administration were 48.21 μg /dl and 39.12 μg/dl respectively. The study indicated that the presence of phyto chemicals like cynogenic glycosides, phenolics, flavonoids, terpenoids and saponin in H. suaveolens seeds could have contributed to the toxicity against for C. cephalonica larvae.
