Glandular hairs are a possible means of limiting aphid damage to the potato crop

Tema(s): Recursos en línea: Resumen: Glandular hairs on leaves and stems stuck naturally-occurring aphids to field grown plants of Solamm polyadenium, S. berthaultii, and first and second generation hybrid S. tuberosum cv. Pentland Crown x berthaultii, but none became stuck on Pentland Crown. S. polyadmium had most glandular hairs, stuck most aphids and had fewest free aphids. In the glass-house, 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.
