Botanical Based Safe and Nontoxic Mosquito Impregnated Gel

Abstract

Mosquito problem is the major problem in our country to compete the mosquito generating problems  there are many formulated products are available in the market but due to some harmful effect on human beings there is urgent requirement of safe and effective formulation. The aim of this study is to develop an effective, safe and slow release formulation against mosquito control. In the present study, First neem microemulsion was prepared then further this microemulsion was converted into microemulsion gel by using polymeric gel matrix Carbopol-934. Microemulsion has globular size in nano range and thermodynamically stabilized formulation so, these characteristic features of microemulsion will remain in the gel phase. Size and zeta potential of microemulsion gel are 400nm ± 6nm and -10.0 mV respectively. synersis, spreading coefficient value are in the range of stabilized gel formulation and suitable for impregnating mosquito net. Neem microemulsion based gel impregnated net gives 90% repellency against mosquitoes.
