Abstract:
Mosquito causes severe human health diseases which may cause death of humans. It
is responsible in causing sever diseases such as malaria, dengue, elephantitis etc.
Thus, to overcome this problem many chemical repellents are being used. Longer
time use of these chemical based repellent causes health issues that would be very
harmful to humans. Thus, in this current investigation we are formulating herbal
based mosquito repellent in order to avoid skin related problems, neurological
disorders, and other health issues. The plants are the reservoirs of naturally occurring
chemical compounds and structurally diverse bioactive molecules. Plants are
recognized for their broad spectrum of pharmacological activities. The biological
activities as secondary metabolites and phytochemicals derived from different plant
parts as leaves, flowers, seeds, bark, root, and pulp. Current investigation suggests the
beneficial use of various phytochemicals, essential oils and plant extracts that are used
to kill mosquito. These phytochemicals such as alkaloid , flavonoid , saponoid ,
tannins , cardiac glycoside , glycoside , terpenoids , phenols , coumarins , phytosterol
. These phytochemicals showed beneficial effects to overcome the use of chemical
repellents. Our investigation showed alkaloid, flavonoid, saponoid phytochemicals as
the best effective measure for killing of mosquito. Nature plant extracts and essential
oils such as neem oil, camphor, coconut oil, orange peel, lemon grass oil, peeled oil
etc. are used to formulate herbal mosquito repellent. Neem oil and lemon grass oil
showed the best effective against mosquito. For further testing cage test was
employed for Larvicidal activity. As a result, it showed 99% activity against mosquito
that were gradually killed by the beneficial effects of essential oils and prominent
plant extracts used in cage test.
