Environmental DNA (eDNA) Analysis

It has been found that Environmental DNA (eDNA) analysis can contribute towards effective pest control. Rsearchers have detected eDNA of Argentine ant in surface soil samples from two different sites: Port Island on Kobe and Fushimi District in Kyoto.

This eDNA analysis method can be used to allow scientists to make an accurate understanding of the hotspots and the habitat distribution for ant species which can cause environmental destruction, for example, the fire ant.

By combining this method of eDNA analysis with pest control activities against ant species which are invasive will create the formulation of measures that can help in controlling such destructive pests. The fire ant which causes significant damage to the environment can be controlled through the use of eDNA analysis.

Environmental DNA (eDNA)

The DNA that is obtained from various environmental samples such as soil, water, air, snow, etc. They can also be obtained directly from individual organisms as interacting with the environment can cause them to disperse DNA to their environmental surroundings. Some examples of eDNA source are carcasses, skin shed by different organisms, faeces, mucus, hair samples etc.

Argentine Ant

Argentine ant (scientific name Linepithema humile) is native to the countries of Argentina, Paraguay, Southern Brazil, Uruguay and Bolivia. It is an invasive species that causes environmental damages and can be found in many places such as Japan, New Zealand, South Africa, Australia, Hawaii, etc. They have been unintentionally introduced to different regions by humans.
