Technology for Mosquito Larvicidal Preparations
Based on Rabdosia sp.
Introduction
An Indian institute
has developed technology for mosquito larvicidal preparations
based on rabdosia sp. The essential oil of rabdosia
melissoides and its phenolic and non-phenolic constituents
have been developed as potential mosquito larvicidal
products. The emulsifiable concentrates (ECs) developed
after incorporating these products have been found to
be highly effective against the 4th instar larvae of
mosquito culex quinquefasciatus in the laboratory evaluation
studies. Twelve recipes that have been developed revealed
LC50 in the range of 0.0004 to 0.015%.
The formulation process is simple.
It employs the aforesaid active materials along with
a solvent and emulsifiers. When added to water,the concentrate
forms emulsion which is effective against the insect.
It can be added to water, as such, at the contaminated
sites or diluted with water to spray at the desired
places. The developed EC is environment friendly and
conforms to the requirements of Bureau of Indian Standards
for similar concentrates.
Areas of Application
Mosquito larvae control in various
stagnating water situations. Its herbal origin coupled
with a sweet fragrance makes it particularly more useful
in situations like domestic water coolers etc.
