How to spot it
You will notice the yellow-black striped Colorado potato beetle and its red larvae can strip a potato field bare in a few days. The females lay orange-colored eggs on the underside of the leaves; from them hatch the voracious larvae that cause the greatest damage.
Prevention
You can collect beetles, larvae, and the orange eggs by hand regularly from May onward. For small plots this is the most effective method. Cover early with insect netting and maintain a wide crop rotation so that overwintering beetles in spring do not find fresh potatoes directly.
