Family Encyrtidae Walker, 1837.

Abstract Species from the family Encyrtidae are all endoparasitoids and some are polyembryonic. Many species have been used successfully in various biological control programmes in different regions of the world. This chapter provides a checklist for the family Encyrtidae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the encyrtid fauna of Iran with adjacent countries indicates that the faunas of Russia (492 species) and Turkmenistan (246 species) are more diverse than Iran (236 species), followed by Armenia (174 species), Turkey (165 species), Azerbaijan (159 species), Kazakhstan (148 species), Pakistan (62 species), Saudi Arabia (47 species), Afghanistan (32 species), Iraq (seven species), United Arab Emirates (three species), Oman (two species), Kuwait (one species) and Bahrain and Qatar (no species). Among the adjacent countries, Russia shares 129 known species with Iran, followed by Azerbaijan (105 species), Turkey (98 species), Armenia (91 species), Turkmenistan (67 species), Kazakhstan (64 species), Pakistan (27 species), Afghanistan (17 species), Saudi Arabia (16 species), Iraq (five species), United Arab Emirates (three species) and Oman (two species).
