Summary Increased methylation of middle lamellar pectin in plants hinders aphids in penetrating host-plant tissue. In sorghum, a new aphid biotype has overcome this host-plant barrier by having increased pectin methylesterase activity. Results suggest that resistance in crop-plants against sap-feeding insects may possibly be manipulated by altering middle lamellar chemistry either through breeding or use of certain plant-growth regulators.
