If you have problems with Colorado Potato Beetles, try to get Lady Bugs on your potatoes or Eggplant plants early. The lady bugs won't get rid of the mature CPBs but WILL feast on the larva enough to keep them at a reasonable level.
I've done it for eggplant for quite a few years. I'm not sure how well it works for potatoes. But what does work for potatoes is to plant some of the oriental eggplant plants (those with the purple caylix ) around your potatoes. CPBs LOVE the oriental eggplant and will destroy them in a few days. They make a perfect trap crop for CPBs.
