摘要: Abstract:The bio-efficacy of Hedychium coronarium Rhizome extract and copepods Megacyclops formosanus, were tested against first to fourth-instar larvae and pupae of dengue Vector Aedes aegypti under laboratory conditions. Different solvent extracts of H. coronarium, combined with copepod M. formosanus showed considerable mortality against A. aegypti. The median lethal concentration value (LC50) observed for the larvicidal and pupicidal activities against mosquito vector species A. aegypti value were 38.59, ppm; no mortality was observed in the control group. This study was also initiated to test the predatory efficiency of copepod against different larval instars and predatory efficiency was noticed at the laboratory and efficiency was higher after the combined treatment with H. coronarium extract. This is an ideal eco-friendly approach for the control of vector control programs.
