Mosquito larvicidal efficacy of leaf extract from mangrove plant Rhizophora mucronata (Family: Rhizophoraceae) against Anopheles and Aedes species

Author(s): S.V.Meenakshi and K.Jayaprakash
Abstract: The crude extract of mangrove plant Rhizophora mucronata was prepared in this present work. The extract was testified for its anti-mosquito larvicidal property against two species of mosquito viz: Anopheles stephensi and Aedes aegypti. The 48 hours exposure of various dilutions of 100, 200, 300, 400, 500 ppm were given to the III to IV instar larval population. Percentage mortality data was analyzed statistically and compared. The larva of Anopheles stephensi was more susceptible than Aedes aegypti. This concept was substantiated by comparing the LC50 values of IIIrd instar larva of both species. The results of histochemical demonstration for acetyl cholinesterase in supra esophageal ganglion had revealed the inhibition of acetyl cholinesterase by the treatments of plant extract. The above results are discussed with the advantages of bioactive anti mosquito larval compound.
