The outbreak of mosquito borne diseases, particularly in dengue fever has become a perennial problem in our country and much attention has been given to control the disease. One of the current methods used in combating mosquito vectors is larviciding. However, synthetic chemicals which are used in the process are quit expensive and have been found to give detrimental affects in our environment.
This problem prompted the researchers to work on the “Feasibility of using derris extract as a natural and biodegradable larvicide in the control of Aedesaegypti”, a common carrier of dengue fever.
In the experiment, four bottles, each with ten collected Aedes larvae were treated with four derris extract concentrations while in one bottle served as control. Mortality of the larvae was measured every hour for ten hours.
The investigatory project gave an encouraging results because the larvae treated with pure and 75% extract concentration resulted to 100% mortality while that of the 50% extract concentration went as far as 70% mortality.
