One of the only places I've seen a list of companion plants with references is in Robert Kourik's 1986 book, Designing and Maintaining Your Edible Landscape Naturally.

He footnotes each item so that you can see which particular bugs were deterred (or not) by a specific plant combination. More research is needed! As far as I know, the list is not available online, and I don't know of anyone else who has compiled a list like that since then. Most of the lists I've seen don't list citations, or they're more general.
More useful, I think, is to plant several clumps of plants specifically for beneficial insects, so that once they eat the first flush of aphids, they will stay in your garden. Plants with tiny flowers and native plants are good bets. In my garden, I always find several lady bugs on my yarrow plants, and last week several soldier beetles. In general, flowers in the daisy, parsley, and mint families attract beneficials and pollinators. The tiny disk flowers in daisy-family flowers are the ones that attract beneficials, so choose single rather than double flowers. It's also important to make sure something is in bloom at all times. I let my brassicas go to flower in early spring for this reason, and I plant oregano primarily for the bees.
Another search term that may be useful is succession planting, which is being ready with seed-grown transplants to fill in holes with a succession crop as soon as space opens up in the garden. For instance, once I harvest garlic and onions, which are growing at the edges of my raised beds, I will have space to plant beets or bush beans. (But I don't usually grow bush beans in advance unless I'm testing the germination of older seeds.)
