Popis:	The feeding behavior of the generalist predator Nabis punctipennis Blanchard (Nabidae) on Acyrthosiphon pisum Harris (Aphididae), two hemipterans common in alfalfa in Chile, was studied in a laboratory experiment using A. pisum, and Aphis craccivora Koch (Aphididae) as alternative prey, which is another common aphid in alfalfa. The presence of A. craccivora did not affect the predation of A. pisum by N. punctipennis. This finding on the predatory behavior of N. punctipennis is valuable to evaluate the potential of this nabid as a biological control agent of A. pisum.
