BAEC develops Aedes mosquito controlling method

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.
