which is to evaluate the formulated herbal as a potential mosquito

COMPARATIVE STUDY OF THE EFFICACY OF OILS OF Azadirachta indica and Zingiber officinale IN FORMULATION
WITH COMMERCIAL MOSQUITO REPELLENT AGAINST Aedes aegypti (DIPTERA: CULICIDAE)
The research was undertaken to evaluate the efficacy of a formulated
herbal with Ginger oil and Neem oil as a potential mosquito repellent.
Identification tests were performed including physicochemical
characterization and instrumental assay. It was also supported by the FTIR
result which shows the functional groups present in the Ginger oil and
Neem oil. Both oils contains ketone/ ester/ carboxylic acid carbonyl stretch
and aromatic ring which is their characteristic functional group of
triterpenoids (Neem) and sesquiterpenes (Ginger). The repellency testing
conducted by the researchers was laboratory evaluation (arm-in-cage set-
up) wherein five treatments were used against Aedes aegypti. The results
showed that formulated herbal (2G:5N) is an effective repellent and is more
effective than formulated herbal (2N:5G) in %P.
