BDF should be used to fight armyworm invasion

These are Botswana, Malawi, South Africa and Zambia. The worst devastation is found in South Africa where four provinces are under siege.

And what are these insects and their origins? The African armyworm is also known by its scientific name spodoptera exempta. There are several types of armyworms that are found in other parts of the world andthey attack a variety of crops. The African armyworm particularly targets maize crop and may divert to other plant species if its primary diet diminishes in the fields. These caterpillars derive their military name from the way they invade large areas and move with the blitzkrieg speed like the German Panza divisions of the Second World War.
