1 Introduction

The family Encyrtidae(Hymenoptera: Chlacidoidea)included approximately 4 000 nominal species in 483 genera(Noyes 2009). Most these beneficial insects are primary or secondary parasitoids, and attack the eggs, larvae or pupae of several arthropod groups such as Diptera, Coleoptera, Hemiptera, Hymenoptera, Lepidoptera, Neuroptera, Orthoptera and also Acarina(Ferrière 1953). Within these vide range of hosts, these parasitoids have efficient role in biological control of agricultural and forest pests(Trjapitzin,1989;Godfray,1994;Hayat,2006). Therefore, a number of encyrtids has been used successfully for control of mealybugs pests(Pseudococcidae)and many soft scale(Coccidae)(Noyes,1985;Huang and Noyes,1994).

The fauna of Iranian Encyrtidae is rather diverse, because in total 93 species are listed in the checklist Fallahzadeh and Japoshvili(2010), and also after publishing the mentioned checklist, totally 54 new records were published by Lotfalizadeh(2010), Golpayeganietal.(2010) , Ghaharietal. (2010), Abd-Rabouetal. (2011), Ghahari and Abd-Rabou (2012), and Rastegaretal. (2012). The aim of this paper is introducing 14 species of Encyrtidae as the new records for the fauna of Iran.

2 Material and Methods

The specimens were collected by Malaise trap, sweeping net and rearing method. In rearing method the leaves of plants infested with scale insects(Hemiptera: Coccoidea)were collected and reared. The samples were put in gelatine capsules separately and then taken in the incubator(25±2 ℃, 65±5% RH, 14:10 L:D), and therefore the parasitoids were emerged from the parasitized hosts gradually. The collected specimens were slide-mounted for further study using the method outlined by Noyes(1982). The wasps were then identified by the 3rdauthor based on the morphological characters such as wing venation, shape and color of antennal segments using available identification keys(Prinsloo,1984;Noyes and Hayat,1994). The information concerning locality, altitude(in brackets)and date of collection, and number of specimens(in brackets)is noted for each species.

4 Discussion

In this faunistic survey 14 encyrtid wasps are listed as the new records for Iran. With considering the checklist of Iranian Encyrtidae(Fallahzadeh and Japoshvili,2010) and 54 new country records excluded in the checklist(Lotfalizadeh,2010；Golpayeganietal.，2010；Ghaharietal.，2010;Abd-Rabouetal.,2011;Ghahari and Abd-Rabou,2012;Rastegaretal.,2012), totally 161 encyrtid species have been recorded from Iran so far. Upon the several sampling trips in different regions of Iran and collecting numerous Chalcidoidea specimens by the first author, it is estimated about 250 encyrtid species as Iranian fauna. Since these parasitoids have efficient role in biological control of pests, determining their hosts is necessary as the first step for conserving and application them in biological control programs.
