Aedes aegypti to Some Common Household Substances and Water from Conspecific Larvae
Dr Rina Tilak*, Maj Vivek Gupta+, Maj Vani Suryam#, Mrs JD Yadav**, Brig KK Dutta Gupta++
Abstract
Background:
The surveillance of Dengue vector - Aedes aegypti, is routinely done by using ovitraps (a dark container filled with water and a wooden paddle/towel cloth provided as a oviposition substrate), which indicates the extent of Aedes activity in an area.
Method:
The study evaluated the oviposition responses of laboratory bred gravid Aedes aegypti to commonly available household substances by use of ovitrap method.
Results: Oviposition avoidance or deterrence was exhibited by gravid Aedes to ovitraps baited with salt, fenugreek, vinegar, lime juice, hibiscus leaves, radish and curry leaves, whereas positive oviposition response was noticed to waters from conspecific (of the same species) larvae and cumin seeds baited ovitraps.
Conclusion:
The study findings may be utilized by researchers for further
chemical analysis of the active ingredients of the
substances found promising with a view to explore the possibility of their
use by community and individuals for Aedes surveillance
and control.
