Abstract

The current study was conducted to evaluate bioassay of both Acorus calamus Linn. crude hexane extract and Cypermethrin 80SC against the 4th instar larvae and adults of Aedes albopictus and Aedes aegypti with LC50 and LC90 values. LC50 and LC90 values of Cypermethrin on the 4th instar larvae of A. albopictus were 0.1470 and 0.6120 ppm respectively while on the A. aegypti were 0.0047 and 0.0108 ppm respectively as compared to the Acorus calamus extract on the 4th instar larvae of A. albopictus were 4.1360 and 22.2766 ppm respectively while on the A. aegypti were 5.4420 and 12.4938 ppm respectively. Both Cypermethrin and Acorus calamus extract showed a significant difference (P<0.05). LC50 and LC90 values of Cypermethrin on adults of A. albopictus were 3.5277 and 5.2844 ppm respectively while on A. aegypti were 0.8220 and 3.4267 ppm respectively and a significant difference (P<0.05) was to be found as compared to that of A. calamus extract on the adults of A. albopictus were 52.8842 and 544.1275 ppm respectively while on the A. aegypti were 18.5270 and 344.8478 ppm respectively and no significant difference (P<0.05) was to be found.
