DHAKA, Scientists of Insect Biotechnology Division of
Institute of Food and Radiation Biology of the Atomic Energy Research
Establishment, BAEC, have developed an effective method of controlling aedes
mosquitoes which transmits dengue virus.
Science and Technology Minister Architect Yeafesh Osman today visited the
laboratory at Savar to monitor the various technical aspects of the method,
said a press release.
Bangladesh Atomic Energy Commission (BAEC) Chairman Mahbubul Haque and
Director General of the Atomic Energy Research Establishment Dr M Azizul
Haque were present on the occasion, among others.
During the visit, the minister expressed his satisfaction over the
inventions and ordered that the procedure be taken at the field level soon.
The minister assured all kinds of cooperation on behalf of the ministry.
Concerned scientists informed the minister that research activities on the
application of Sterile Insect Techniques (SIT) method to eradicate dengue
have already been completed.
In the SIT method, male Aedes mosquitoes are sterilized by applying gamma
rays. If the mosquito is exposed to dengue outbreaks, it will meet with the
existing female Aedes mosquito in nature so that no larvae can be matured,
according to the release.
As the larvae are not fertilized, the number of mosquitoes starts to
decrease. It is a very effective and internationally recognized method of
controlling dengue outbreaks.
Besides, it is an environment friendly method, so it has no adverse effect
on the environment.
In this way only infertile male mosquitoes will be exposed to nature.
Since male mosquitoes are unable to carry the dengue virus, there is no
chance of spreading dengue through it. Furthermore, male Aedes mosquitoes do
not bite humans.
So, the Commission's SIT method is able to play an effective role in
controlling dengue outbreaks in the country.
