insects. There are also some egg parasitoids distributed in other families, while other
members of those families are parasitoids of the other stages. In Iran, records of egg
parasitoids are present from Encyrtidae, Eupelmidae, Eulophidae, Torymidae, and
Mymaridae. Mymarids all are egg parasitoid of the other insects but their importance
is very lower than trichogrammatids.
