Abstract
The larvicidal activity of biosurfactants refers to the ability of
these naturally occurring surface-active molecules to kill or inhibit the
growth and development of insect larvae. Biosurfactants, synthesised by microorganisms
such as bacteria, yeast, and fungi, have garnered significant interest for
their potential application in pest management. This interest stems from their
environmentally friendly characteristics and minimal harm to humans and
animals. Here are some key points regarding the larvicidal activity of biosurfactants.
Biosurfactants can be applied in various ways, including as sprays, foams, or
in water bodies where mosquito larvae breed. The choice of application method
depends on the specific insect and environmental conditions. The present study
showed that biosurfactants had larvicidal activity. Early-stage larvae of Culex
sp. were collected from unused ponds on Parangipettai, and a previously
developed biosurfactant was used. Test solution range: 50mg/ml. The larvicidal
bioassay was conducted following the recommendations the World Health
Organisation set forth. The findings of the study indicated that biosurfactants
demonstrated larvicidal action. The biosurfactant had the most excellent
effectiveness, resulting in a death rate of 91.29 ±1.30% when applied at the
highest concentration tested, and 400 ppm. The findings of the bioassays
demonstrated that the results varied depending on the concentration. The
results indicate that using biosurfactants effectively manages the population
of Culex sp. larvae.
