STUDY ON THE PLANT SPECIES, ACORUS CALAMUS FOR INSECTICIDAL PROPERTIES AGAINST THE FILARIAL VECTOR, CULEX QUINQUEFASCIATUS SAY. (DIPTERA: CULICIDAE).
- Culex quinquefasciatus,
- Acorus calamus,
Leaf extract of the species, Acorus calamus was evaluated for the egg hatchability, larvicidal and pupicidal activity and the protein content of mosquito, Culex quinquefasciatus under the room temperature in he laboratory. Dosage value as expressed in ppm was 10 to 140 for Culex quinquefasciatus. A relationship
was observed between the plant extract doses and percentage mortality. The percentage of egg hatchability decreased; larval and pupal mortality were found to be increased with increase in the dosage. Based on the probit analysis, the LC50 value of egg (99.15), I instar (42.24), IV instar (101.49) and pupae (121.57mg/mL)
were recorded. The ovary protein content of the treated (0.083) was estimated to be very low when compared with that of the control (0.172mg/mL).
