Investigation to Evaluate the Mosquito Repellent Activity: A Combination with Natural Binders

In this study, it was attempted to create mosquito-repellent cakes utilizing marigold, calamondin, papaya, and oregano leaves in conjunction with various natural binders. Medicinal plants also play an important role in maintaining biodiversity in forests, fallow and cultivated lands though with modern technology, indoor cultivation (glasshouses, greenhouses, polyhouses) has become popular. Plants are regarded as a secure and reliable method of avoiding mosquito bites. Many plant extracts and oils have a long-lasting ability to keep mosquitoes away (up to several hours). In present work we have produced an effective and purely natural mosquito repellent cake using marigold leaves, calamondin leaves, papaya leaves, oregano leaves to determine if the component present on them are suitable as mosquito repellent. To recognize this new combination and in addition use of natural binder in making these mosquito cakes is innovation of method. Evaluation was carried out in a net cage (45 cm×30 cm×25 cm) containing 100 blood starved mosquitoes. Study provides an herbal repellent with long lasting protection, safe for human life, with no side effect. The combination Paste of leaves + charcoal + 20% cow dung was found to be more repellency against mosquitoes under study. The problem of chemical pesticide resistance may be solved by the discovery of natural compounds with strong phyto-constituents that have insecticidal effects. The finest combinatorial chemist is nature, which provides a wide range of natural chemicals derived from medicinal plants that are useful as medicines, antibacterials, antifungals, insect repellents, cosmetics, etc.
