Is there a different name for calendula?
Both are popular as companion planting here. Calendula is easier as the tagetes is a favourite of the slugs.

Supposedly, the idea that "marigolds" repel pests in a major way is a bit of a myth, and apparently Tagetes only repel soil nematodes while their roots are still in the soil, or something like that, and anyway, I don't know if all of us really have a problem with nematodes.
Both calendula and tagetes grow, bloom, and self-seed like crazy where I live.

You are correct that they don't repel bad bugs in a major way, I was told that the flower sent confuses some insects or covers up the sent of things they like to munch (eat) on, and that makes them fly to a different area. But what helps the most is the attraction of the good bugs like hover flies, lady bugs (lady beetles) etc. As these either eat the bad ones or their offspring eat them. Some good bugs even lay their eggs on caterpillars so keep an eye for that as if you are handpicking the caterpillars and destroying them you may want to leave the ones that have weird barrel shaped objects all on its back as these are the eggs of things like parasitic wasps and will soon hatch and eat the caterpillar and then kill other bad bugs as well so try not to kill those so the good bug population can increase and help you fight the bad bugs.
