• The micro encapsulations and nanoparticles are present solutions that can perform various functions, including the insect repellency.

• The fabric was developed to avoid mosquito bites responsible for skin problems (redness, swelling, etc.) and the transmission of serious diseases such as dengue fever and malaria.

• The clothing Ztop was tested through laboratory testing performed in accordance with the methodologies designated by the World Health Organization The results indicate that the efficacy clothing Ztop presents approximately up to 100 washes.

• Its use can be an effective tool in the prevention of mosquito bites.

• In the case of mosquitoes the solution applied in the finishing of textiles (active principle) acts by blocking the pores of the antennae of female mosquitoes preventing them from landing on his victim, even having been stimulated by the presence of carbon dioxide.

• The effectiveness of the tissues tested was analyzed by estimating the levels of repellency (IRE) and reduction of blood meal (BFI) against the species Anopheles gambiae. For a product to be considered effective these indices should have values ​​close to or above 50 (Müller et al., 2009). The situation repellent permethrin induced by the compound was observed in all tests including those tissues that were tested 100 washes.

• By other studies, it was found that although the index did not suffer major changes repellency (remaining values ​​above 50) when testing / tests are conducted with other species of insects, including species of Aedes. Although the IRE on the Anopheles be higher than the IRE Aedes species differences are quite negligible, and the estimated IRE obtained is always higher than 50.
