First report of Eurytoma cynipsea (Hym.: Eurytomidae) from Iran
زنبور پارازیتوئید Eurytoma cynipsea Boheman برای اولینبار از ایران گزارش میشود. حشرات کامل این زنبور از گالهای ایجادشده بهوسیله زنبور گالزای Aulacidea hieracii (Linnaeus) (Hym.: Cynipidae) روی ساقههای گیاه Hieracium verruculatum Link (Asteraceae) بهدست آمدند. زنبور E. cynipsea در بسیاری از کشورهای منطقه Palaearctic انتشار دارد
First record of the seed-eating wasp, Systole eremodauci (Hym.: Eurytomidae) from Iran
The family Eurytomidae includes economically important wasps, which feed on the seeds of various agricultural, horticultural and rangeland plants. This report is part of a survey conducted during 2009-2012 to identify the seed-eating pests of non-legume rangeland plants in the Fars province of Iran. The eurytomid species Systole eremodauci Zerova, 1994 was collected on ammoniacum plant, Dorema ammoniacum (D. Don.), and is first recorded from Iran
Chromoplex picticollis (Hym.: Ichneumonidae) associated with Asteraceae capitulum: a genus and species new to Iran
گونه Chromoplex picticollis (Thomson) به عنوان اولین گزارش یک جنس و گونه برای فون ایران معرفی میگردد. این گونه از گلآذین کلاپرک گیاه Echinops sp. (Asteracea) که همزمان توسط Tephritis sp. dioscurea group (Dip.: Tephritidae) آلوده شدهبود، پرورش یافت. این مطالعه در سالهای 1392-1394 در شمالغرب ایران، استان آذربایجانشرقی، منطقه ارشدچمنی انجام شد. ویژگیهای مورفولوژیک افتراقی و پراکنش C. picticollis ارائه میگردد

Two new records of Chalcidoidea (Hymenoptera) from Iran
دو گونه از زنبورهای پارازیتویید بالاخانواده Chalcidoidea (Hymenoptera) و همچنین، روابط میزبان- پارازیتوییدی آنها روی گیاه Scariola orientalis Boissier برای اولینبار از ایران گزارش میشوند: گونه Pteromalus sequester Walker (Hym.: Pteromalidae) پارازیتویید داخلی، انفرادی و لاروی- شفیرگی مگس Hypenidium oculatum (Becker) (Dip.: Tephritidae) و گونه Discodes rubtzovi Sugonjaev (Hym.: Encyrtidae) پارازیتویید شپشک Cerococcus longipilosus (Archangelskaya) (Hem.: Cerococcidae)

(Asteraceae) از تیره مرکبان جمعآوری و پرورش داده شد. این گونه برای اولین بار از ایران گزارش میشود
An overview of the Leucospidae (Hymenoptera, Chalcidoidea) of the Arabian Peninsula with description of a new species
An overview of the family Leucospidae (Hymenoptera, Chalcidoidea) is provided for the leucospid fauna of the Arabian Peninsula. Two genera containing four species are identified based on morphometrics and colour patterns. One species, Leucospis ayezae Usman, Anwar & Ahmad, sp. nov., is described. Leucospis elegans Klug had been previously recorded from Arabia Felix (= Yemen) and is recorded here for the first time from Saudi Arabia. The status of Leucospis aff. namibica from Yemen has been clarified, and this species is placed here in the genus Micrapion Kriechbaumer as M. clavaforme Steffan. An updated key and a map showing the distribution of the family Leucospidae in the Arabian Peninsula is provided. The occurrence and color morphs of all leucospid species that have been recorded so far from the region are briefly discussed
Can the understory affect the Hymenoptera parasitoids in a Eucalyptus plantation?
The understory in forest plantations can increase richness and diversity of natural enemies due to greater plant species richness. The objective of this study was to test the hypothesis that the presence of the understory and climatic season in the region (wet or dry) can increase the richness and abundance of Hymenoptera parasitoids in Eucalyptus plantations, in the municipality of Belo Oriente, Minas Gerais State, Brazil. In each eucalyptus cultivation (five areas of cultivation) ten Malaise traps were installed, five with the understory and five without it. A total of 9,639 individuals from 30 families of the Hymenoptera parasitoids were collected, with Mymaridae, Scelionidae, Encyrtidae and Braconidae being the most collected ones with 4,934, 1,212, 619 and 612 individuals, respectively. The eucalyptus stands with and without the understory showed percentage of individuals 45.65% and 54.35% collected, respectively. The understory did not represent a positive effect on the overall abundance of the individuals Hymenoptera in the E. grandis stands, but rather exerted a positive effect on the specific families of the parasitoids of this order
