Abstract

TPB, the tarnished plant bug (Lygus lineolarisj, attacks strawberries in Iowa and the Midwest. The egg parasitoid (Anaphes \o\e) has been observed to parasitize TPB in several crops in the western United States, but its activities have not been studied in strawberries in the Midwest. Under laboratory conditions, it was determined that A. iole will parasitize TPB eggs in strawberry stems. Releases of A. iole females in large field cages containing low densities of TPB eggs did not result in successful parasitization.
