You see a photo of a mosquito, the medium for the spread of dengue fever, in the photo. Well, if what Indian scientist found is true, we now have a natural source of another weapon against this pesky pest. The Indian scientists found that extracts from berries of a weed, Solanum villosum, was effective as a natural insecticide against Stegomyia aegypti, the mosquito which is the vector for spreading of the deadly dengue fever.
The Indian scientists also said that disease-spreading mosquitoes are increasingly resistant to synthetic insecticides, so having a natural alternative is important. However, I was told that this cannot be true as mosquitoes have too short a life cycle to develop that resistance to insecticides. Who exactly is correct I am not sure yet, but a natural insecticide is a definite welcome to our stock of insecticides against disease-spreading mosquitoes which are a nuisance enough even without their life-threatening ability to spread deadly diseases.
