SUMMARY Glandular hairs on leaves and stems stuck naturally‐occurring aphids to field grown plants of Solamim polyadenium, S. berthaultii, and first and second generation hybrid S. tuberosum cv. Pentland Crown × berthaultii, but none became stuck on Pentland Crown. S. polyadenium had most glandular hairs, stuck most aphids and had fewest free aphids. In the glasshouse, the percentage of stuck aphids was positively correlated with the abundance of glandular hairs, especially on the leaves, so counting the hairs may be a simple preliminary method of screening for aphid‐trapping ability.
