Efficiency Of Water and Ethanol Alcohol Extract Of Eucalyptus camaldulensis Leaves On Mortality Mosquito Larvae of Aedes caspius pallas in AL-Kut city/ Iraq

Abstract

The study evaluated the effectiveness of the water and alcohol extracts of Eucalyptus camaldulensis Dehnhardt leaves in killing of the 3rd-4th instar larvae of Aedes caspius pallas collected from Wheat and Barley fields in AL- Kut city, Wasit province / Iraq. During the period of five months ( November 2013- May 2014). The results from statistical analysis showed significant difference between alcoholic extract and the water extract and the concentrations of Eucalyptus camaldulensis leaves (0.05) recorded high mortality rate in concentration 10000ppm with 100 % to alcoholic extract and mortality rate to water extract with 90 %. As well as the alcoholic LC50 and LC90 that were given to same species, were calculated and the results were (8, 2700 ppm) respectively. Whilst the water extract at the same lethal concentrations findings were (2500, 9900 ppm) respectively.
