The Dhaka South City Corporation (DSCC) has found the recently tested sample of insecticide effective against mosquitoes after waiting 24 hours of the initial spray.
The Aqua K Othrine insecticide (Deltamethrin 2%) underwent tests on Friday at the Nagar Bhaban.
After the successful test, the DSCC decided to send the samples of pesticides to the Institute of Epidemiology, Disease Control and Research (IEDCR) and the Plant Protection Wing for approval.
As part of the test, a sample of K Othrine was sprayed to three net cages containing 50 mosquitoes each. After 24 hours, 100, 98 and 80 percents of mosquitoes contained in the three cages were killed, confirmed a DSCC official on condition of anonymity.
The new insecticide is water soluble, but the existing fogger machines (used for spraying insecticides) need diesel to operate. So, new machines will be needed to spray K Othrine.
The K Othrine samples were collected from Indian agent of multinational company “Bayer Corporation.”
Shuvo Dey, the representative of the corporation recently told reporters that the new insecticide is effective and environment friendly.
“To test the effectiveness of the pesticides, it is necessary to wait 24 hours,” he told The Business Standard.
On Friday, officials revealed that after 30 minutes of spraying the insecticides, 26, 22 and 18 percents of the mosquitoes died inside the net cage.
