The Emerald Ash Borer is recognized as a significant pest, particularly for ash trees, but it does not belong to the group of the three most famous borers or bark beetles associated primarily with pine and other coniferous trees.

The IPS Beetle, Southern Pine Beetle, and Black Turpentine Beetle are well-known borers that specifically affect southern pine ecosystems. The IPS Beetle is notorious for its role in pine tree decline, particularly during times of environmental stress. The Southern Pine Beetle is one of the most destructive bark beetles in North America, responsible for widespread tree mortality in southern pine forests. The Black Turpentine Beetle typically infests pine trees, creating significant economic and ecological impacts.

In contrast, the Emerald Ash Borer primarily targets ash species and is a relatively recent introduction to North America, affecting a different set of trees than the aforementioned beetles. Therefore, it is correctly identified as the option that does not belong in the category of the three most recognized borers or bark beetles affecting pine forests.
