Now mosquitoes that spread dengue will not be born from larvae, bacteria will sterilize – Research


Bacteria Killed Dangerous Mosquitoes : Every year, mosquito-borne diseases have a challenging season for doctors around the world. Various measures are taken to prevent diseases spread by mosquitoes. Many types of chemicals are also being used to kill mosquitoes. But due to the increasing use of these chemicals, immunity is also developing in mosquitoes. This makes it difficult to get rid of the mosquito menace. At the same time, such chemicals also harm the environment, so one made in Australia Experiment It has been found that mosquitoes that spread diseases such as dengue can be eliminated with a specific bacteria.

According to the report published in Dainik Jagran newspaper, a team of researchers from Commonwealth Scientific and Industrial Research Organization (CSIRO) has found that Wolbachia Bacteria Germ carrier Mosquito (Wolbachia Bacteria Germ carrier Mosquito) can successfully starize Aedes Aegypti. could.

How was the trial done?
Researchers released nearly three million sterilized mosquitoes at three trial sites in Queensland in their 20-week experiment in 2018. When female aegypti mosquitoes come in contact with sterilized male mosquitoes, they produce eggs or larvae, but mosquitoes cannot breed from them. After this, CSIRO researchers found that in 12 months the mosquito outbreak (population) at the trial sites decreased by 80 to 97 percent. It is being told that this technique can be adopted for the prevention of Aedes albopictus, the Asian tiger mosquito that spreads the virus.

The trial was conducted in collaboration with CSIRO, University of Queensland, Verily Life Sciences, QIMR Berghofer Medical Research Institute and James Cook University in international collaboration. Scott Ritchie, Adjunct Professor at James Cook University, said the Wolbachia trial was a successful international collaboration that saw contemporary science working together with state-of-the-art technology to help fight the spread of dengue, Aedes aegypti. May help in eliminating mosquitoes.

He said, “It was a hugely successful project. We reared the three million male Aedes aegypti mosquitoes needed for testing in the germ at James Cook University in Cairns.”

What diseases does the Aedes aegypti mosquito spread?
Let us tell you that Aedes aegypti is responsible for the spread of dengue fever, yellow fever, Zika virus and other diseases. In research, it was found that millions of people in more than 120 countries of the tropical zone are vulnerable to diseases spread by mosquitoes.
