Effect of crude ethanol extract of Tamarix aucheria and Suadae vermiculata on mortality larvae instar of Culex pipiens

Culex pipiens mosquitos are thought to be vectors for many arboviruses, including West Nile virus and encephalitis virus, which have a global impact on human health. The natural management of this pest s aquatic stages is critical for sustaining an insecticide-free environment. The current study focused on the biological and biochemical effects of crude ethanol extract of Tamarix aucheria and Suadae vermiculata on Culex pipiens laboratory colony larvae of instar. The results showed the effect of overlapping the concentrations of crude ethanol extract T. aucheria and S. vermiculata on mortality of the first and second larval instars of C. pipiens mosquito which seems the exceed T. aucheria more than T. harizanium in mortality of first and second larva instars and for all concentrations. The concentration of 150ppm and of 120 hours exposure showed effective concentrations in mortality for all plants.
