However, when underdressed by pests, such as when ants destroy the roots, plants are known to produce chemicals toward of invaders. So for the study, Barbero and her colleagues grew oregano in enclosed terrarium with Myrmica ants, and then collected the chemical since admitted to produce chemicals toward of invaders. The researchers found that the plants made twice as much of a chemical agent called carvacrol versus normal plants grown without Myrmica ants. Carvacrol is a known bug killer, but in a surprising twist, researchers found that Mrymica ants switch on a set of jeans that neutralize oregano chemical weapon. Meanwhile, other types of ants lack this defense and succumb to carvacol, the team found.
