Comparing larvicidal Effect of Methanol Extract of the Aerial Parts of Henbane (Hyoscyamus niger L.) and Oleander ( Nerium oleander L.) plants on Anopheles spp Larvae (Diptera: Culicidae) in Vitro
Journal Title: Zahedan Journal of Research in Medical Sciences - Year 2017, Vol 19, Issue 3
Abstract
Background: Malaria is an infectious disease by fever and chills, anemia and splenomegaly genus Plasmodium parasite is the agent it. One of the easiest and least expensive methods to prevent this disease is removing the vector that usually by been done insecticides and chemical pesticides, but nowadays due to the damaging effects of by toxic chemicals is currently trying to organic toxic and plant compounds used to combat the pests. So in this study used from the Hyoscyamus niger L. and Nerium oleander L. to destroy the larvae of this vectors and positive results were compared these two plants together. Methods: In this experimental study, H. niger and N. oleander collected and dried to extraction by methanol usingthe Rotary Evaporator. Mosquito larvae collected from stagnant water pits and ponds around the Birjand, Iran and order to apply the relevant identity tests and isolation of Anopheles spp mosquito larvae. Survival measurement were used to estimate LC50 values using Probit analysis in Excel 2010 and SPSS (ver 20) software. Results: Both Hyoscyamus niger and Nerium oleander had positive effects on destroying the Anopheles spp larvae and between obtained results, the most effective extract for destroying the mosquitoes Anopheles spp larvae, was the flower extract of henbane (LC50 = 0/26 ppm) and the weakest one, was the leaves extract of oleander (LC50 = 4/85 ppm). Conclusions: According to the results, the flower extract of henbane is recommended as a toxic, organic and natural compounds to fight Anopheles spp mosquito larvae, which it is stronger and more effective compared to the other parts of these two plants.
