Frequent Use

The mosquito Aedes aegypti is an epidemic vector of several diseases such as dengue fever and yellow fever. Several pesticides are used to control the mosquito population. Because of their frequent use, some mosquitoes have developed resistance. In the present study, we evaluated the synergistic mosquito-repellent activity of essential oils from Pelargonium radula, Syzgium aromaticum and Citrus aurantifolia against Aedes aegypti by using Y-tube olfactometer. The oils was subsequently analyzed by using GC–MS. These results clearly reveal that the essential oil of C. aurantifolia served as the most potent repellent agent against Aedes aegypti . The results indicate that three constituents; limonene (19.58%) followed by β–pinene (17.12%), geraniol (13.23%) which comprise a large proportion of the C. aurantifolia are likely responsible for the observed repellent activity.

Safe Product

Mosquito repellent is a product that is applied to the skin or other surfaces to deter insects (and arthropods in general) from landing or climbing on that surface. The interest in plant-based repellants has been revived seeing that the development of resistance, cross-resistance and possible toxicity hazards associated with synthetic insecticides and their rising cost. The present study aimed towards the development and evaluation of safe and efficient herbal mosquito repellent from leaf extracts of Azadirachta indica, Vitex negundo, and Ocimum gratissimum. Six different types of formulation (Type-1 to 6) were prepared using each plant extract and optimized ingredients. The mosquito repellent activity of the formulation was tested using the arm-in-cage method. One skin rubbed with a small quantity of formulation was exposed to 20 mosquitoes and the number of mosquitoes that aligned or biting the arm was recorded in each minute for five minutes. The most effective repellent activity of the Type2 formulation was 87.5% (Y-shaped Model) and 91.62% (Rectangular-shaped Model). The Type1, Type3, Type4, Type5 and Type6 formulation showed 66.62% , 58.25%, 68.75%, 70.75% and 62.5% repellent activity in Y shaped model and 66.62%, 62.5%, 70.75%, 83.25% and 62.5% repellent activity in Rectangular shaped model respectively. During these studies, we found that Hexane extract showed higher repellent activity. No allergic reactions were observed upon the skin. So, it is a safe product. The formulation was ecological, economical and highly efficient.
