Searching efficiency and multiparasitism in Aphidius smithi and A. ervi (Hym., Aphidiidae), parasites of pea aphid, Acyrthosiphon pisum (Hom., Aphididae)

Aphidius smithi and A. ervi were introduced into the United States to control aphid pests of alfalfa. Laboratory experiments showed that A. smithi was more efficient in searching for hosts (i.e., more hosts parasitized) than A. ervi, when measured separately. However, when the two species searched t...
