摘要：

Feeding by A. pisum (Harris) (Homoptera: Aphididae) on young pea plants, P. sativum (L.) cv. Alaska, reduced the relative growth rate and efficiency of production of new tissue relative to the amount of leaf area by as much as 118%. These changes were proportional to the number of aphids and length of infestation period and occurred because of reductions in leaf surface area up to 83% and loss of photosynthate which aphids extracted. Reductions were only 1/5-2/3 as large when infestations were delayed for 5 days. Total leaf area of the plants relative to their weights was not decreased.
