Abstract
Three solitary parasites of Nabis americoferus Carayon were found in the San Joaquin Valley of California. Leucostoma simplex (Fallén) (Diptera: Tachinidae) is quite abundant and attacks 4th and 5th-stadial nymphs and adult Nabis. Adult parasite mating and attack behavior were observed, and the reproductive morphology was studied. Larval development through 3 instars required 17–31 days at 80°F. The larva in its 3 stages is described. Intraspecific competition was observed in superparasitized nymphs. A rare parasite, Wesmaclia pendula Foerster (Hymenoptera: Braconidae), also was found to attack nabid nymphs and adults. An egg parasite,Polynema sp. (Hymenoptera: Mymaridae), not previously associated with Nabis in North America, was recovered. Development of the larva and the pupa rerequired 20–23 days at 70°F. The Polynema injected its egg through the plant tissue into the host egg and not through the exposed egg cap.
