why are Grasshopper gather in packs?

Professor P. Simpson (University of Oxford, England) and his colleagues found sensitive hairs on the hind legs of grasshoppers, stimulating the need to gather in their herds.

Understand that grasshoppers are gentle creatures and often live alone. But when stimulated, they merge together into herds, then truly become a major threat to agriculture. This discovery is very important because it is possible to bring people to the production of new pesticides to prevent the gathering of grasshoppers.

' The nervous system communicates through chemicals. If we find those chemicals and how they affect the nervous system (which has made locusts shift from solitary to living in the herd), we can make deep control chemicals. new harm ' - Professor P. Simpson said.
