A faunistic study on the braconid wasps (Hymenoptera: Braconidae) of Iran
Twenty-three species of Braconidae (Hymenoptera) within eight subfamilies, Agathidinae,
Alysiinae, Blacinae, Brachistinae, Braconinae, Cheloninae, Euphorinae, Macrocentrinae, Microgastrinae and
Neoneurinae are recorded for the fauna of Iran. Five species, Macrocentrus grandii Goidanich, 1937
(Macrocentrinae), Apanteles elpis Nixon, 1973, Apanteles urgo Nixon, 1965, Microplitis sofron Nixon, 1970,
and Protapanteles aliphera (Nixon, 1973) (Microgastrinae) are newly recorded from Iran
A faunistic study on Chalcidoidea (Hymenoptera) of Iran
Abstract: The fauna of some families of Iranian Chalcidoidea is studied. In total, 24 species of six families,
Chalcididae (3 species from 3 genera Brachymeria Westwood, Chalcis Fabricius and Dirhinus Dalman),
Encyrtidae (7 species from 6 genera Anagyrus Howard, 1896, Copidosoma Ratzeburg, 1844, Diversinervus
Silvestri, 1915, Encyrtus Latreille, 1809, Microterys Thomson, 1876 and Syrphophagus Ashmead, 1900),
Eupelmidae (8 species from 4 genera Anastatus Motschulsky, Eupelmus Dalman, Eusandalum Ratzeburg and
Pentacladia Westwood), Eurytomidae (3 species from 2 genera Eurytoma Illiger and Tetramesa Walker),

Perilampus Latreille) were collected and identified
Laboratory Bioassay of Iranian Isolates of Entomopathogenic Fungus Metarhizium anisopliae (Metsch.) Sorokin (Ascomycota: Hypocreales) against two Species of Storage Pest
The susceptibility of adults of Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) and Oryzaephilus surinamensis L. (Coleoptera: Silvanidae) to three Iranian Isolates of the entomopathogenic fungi Metarhizium anisopliae (Metsch.) Sorokin was evaluated through bioassays with direct immersion under laboratory conditions. For each isolates, five aqueous suspensions were prepared in a logarithmic series in Tween 80 (0.05% v/v). Results showed that adult of both species were susceptible to all isolates of M. anisopliae. For all three isolates, mortality percentage of the two species increased with increasing conidial concentration and significant difference was observed between concentrations. The corrected cumulative mortality of adult of O. surinamensis 10 days after immersion ranged from 12.38 to 85.84%, 18.6 to 62.83% and 10.63 to 77.87% for different concentrations of DEMI001, IRAN 715C and IRAN 1018C, respectively. These amounts for T. castaneum varied from 31.07 to 74.78%, 26.02 to 75.61% and 23.33 to 89.99% for different concentrations of DEMI001, IRAN 715C and IRAN 1018C, respectively. The parameters of probit analysis demonstrated non-overlap of 95% confidence limits of LC50 and LC95 and significant difference was observed among three isolates tested against each insect. The lowest and the highest LC50 and LC95 values were observed in the isolates DEMI001 for O. surinamensis (3/1×105 and 1/5×108) and IRAN 715C for T. castaneum (6.2×108 and 6.9×1014), respectively. This observation highlights the importance and need of screening for more virulent isolates against storage pests for use in the management of these pests

Фауністичне дослідження родини Braconidae (Hymenoptera: Ichneumonoidea) Ірану
In this research, totally 26 species of Braconidae (Hymenoptera) were collected and identified from some regions of Iran: Agathidinae (one species), Alysiinae (four species, three genera), Brachistinae (one species), Cheloninae (four species, single genus), Dirrhopinae (one species), Doryctinae (two species, two genera), Hormiinae (one species), Microgastrinae (six species, three genera), Opiinae (two species, two genera), Rhysipolinae (one species), Rhyssalinae (one species), and Rogadinae (two species, single genus). Five species, Apanteles kubensis Abdinbekova, 1969 (Microgastrinae), Dirrhope rufa Förster, 1851 (Dirrhopinae), Heterospilus (Heterospilus) austriacus (Szépligeti, 1906) (Doryctinae), Microchelonus (Microchelonus) luzhetzkji (Tobias, 1966) (Cheloninae), and Opiostomus (Jucundopius) impatientis (Fischer, 1957) (Opiinae) are new records for the fauna of Iran.В роботі представлені результати дослідження фауни Braconidae (Hymenoptera) деяких регіонів Ірану. Матеріал був зібраний з використанням пасток Малеза, а також за допомогою косіння ентомологічним сачком. Певна кількість матеріалу була опрацьована з ентомологічних колекцій місцевих університетів та природничих музеїв. Загалом зібрано та ідентифіковано 26 видів Braconidae: Agathidinae (1 вид), Alysiinae (4 види, 3 роди), Brachistinae (1 вид), Cheloninae (4 види, 1 рід), Dirrhopinae (1 вид), Doryctinae (2 види, 2 роди), Hormiinae (1 вид), Microgastrinae (6 видів, 3 роди), Opiinae (2 види, 2 роди), Rhysipolinae (1 вид), Rhyssalinae (1 вид) та Rogadinae (2 види, 1 рід). П’ять видів, а саме – Apanteles kubensis Abdinbekova, 1969 (Microgastrinae), Dirrhope rufa Förster, 1851 (Dirrhopinae), Heterospilus (Heterospilus) austriacus (Szépligeti, 1906) (Doryctinae), Microchelonus (Microchelonus) luzhetzkji (Tobias, 1966) (Cheloninae) і Opiostomus (Jucundopius) impatientis (Fischer, 1957) (Opiinae) – є новими знахідками для фауни Ірану. Результати цього дослідження вказують на те, що фауна іранських родини Braconidae Ірану є дуже різноманітною і в той же час маловідомою для широкого кола дослідників. Фауністичні дослідження іранських браконід проводились не в усіх районах. залишається кілька регіонів, де не проводився систематичний, регулярний збір матеріалу, особливо це стосується східної та південної частини країни. Слід відмітити, що представники родини мають певне практичне значення для використання в біологічному методі контролю деяких видів сільськогосподарських та лісових шкідників. Охорона популяцій цих видів-паразитів має неабияке практичне значення в контексті зменшення чисельності популяцій комах-шкідників
