Summary Two different types of artificial leaf damage, crushing and cutting, were assessed for their effects on the growth and survival of Rhopalosiphum padi caged on maize (cv. LG11) leaves. Crushing significantly reduced aphid growth rate by up to 23% and their survival by five to six times, while cutting had no significant effects. Although the area of tissue involved was lower for crushing relative to cutting ( c. 5% and 10% respectively), the greater level of cellular damage inflicted by crushing may have resulted in more phytochemical changes. These effects suggest that the feeding of one herbivore guild such as leaf chewers may adversely affect the performance of another, such as phloem feeders.
