Chemicals Based
Technologies - 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.
