Nanoparticle of Silver Nitrate (Ag2NO3) and Carbamate (CO2NH3 derivatives) For Vector Control of Aedes aegypti

Abstract

The climate change has an impact on various lives, including in the vector breeding. The Aedes aegypti resistance as an infectious agent of dengue fever is harmful for life, especially to non-target organisms and the environment. Nano-silver (Ag2NO3), is a new form of engineering in vector control. The aim of this research was the toxicity test of nano-silver (Ag2NO3) and carbamate (CO2NH3 derivatives) on Aedes aegypti larvae. This was a laboratory research (true experiment), used for 3-4 instar stage larvae toxicity test . The number of samples was calculated using an experimental approach, with a completely randomized design. As simply, can formulated as follows, (t-1) (r-1)> 15. The amount of this samples were 14. The toxicity test with carbamate compounds, at concentration 0.01 mg / l as many as 80% larvae were death, whereas on concentrations 0.5 mg / l as many as 92% of the test animals were death. Toxicity test with nano-silver on concentration 0.3 mg / l, all of the test animals (100%) experienced were death. The results of the observations also showed that the instar more active in the low cocentration of Ag2NO3 (0.01 mg/l - 0.1 mg/l). The conclusion are, nano-silver is more effective than carbamate compounds, and there is a potential for resistance.
