Braconid wasps (Braconidae) are one of the most important pest parasitoids. The function of parasitoids can be affected by the use of insecticides. In order to use biological control agents and pesticides simultaneously in pest management, it is necessary to know the effect of pesticides on biological control agents. In this study, the lethal and sub lethal effects of the flubendiamide, emamectin benzoate+lufenuron, thiocyclam and spinosad on the parasitoid Habrobracon hebetor</em> (Say) (Hymenoptera: Braconidae) were investigated. The LC50</sub> of spinosad on parasitoid wasps were 1.25 mg/L of active ingredient, which showed that this insecticide is the most toxic compound on this insect and LC50</sub> of thiocyclam, emamectin benzoate+lufenuron and flubendiamide were 19.99, 7.56 and 6.45 mg/L of active ingredient respectively, which were more toxic to this wasp, respectively. The results of bioassays on adult insects of parasitoid wasps showed that spinosad with LC30</sub> was 0.71 mg /L of active ingredient with high toxicity on adult insects compared to flubendiamide, emamectin benzoate+lufenuron and thiocyclam, which were LC30</sub>, 3.67, 4.26 and 14.44 respectively. According to the classification of the International Organization for Biological Control, spinosad was in the group of harmful insecticides and emamtectin benzoate + lufenuron and flubendiamide were in the group of moderately harmful insecticides. According to this classification, thiocyclam was classified as harmless insecticide on bracon wasp.

The Chrysididae (Hymenoptera: Chrysidoidea), commonly known as cuckoo wasps or emerald wasps, are a cosmopolitan family of aculeate wasps and include about 3,000 species in the world. Chrysis Linnaeus, 1761 is a large, cosmopolitan and diverse genus in this family (Chrysidinae, Chrysidini), with over 1100 described species and subspecies and many more to be discovered. A list of twelve species of the genus Chrysis collected in the Fars Province of Iran is presented. Specimens were collected by Malaise traps during 2013-2017. The specimens were identified based on morphological characters mentioned in different taxonomic keys and their original descriptions. Six species: Chrysis amneris Balthasar, 1953, Ch. dawahi Strumia, 2011, Ch. diacantha diacantha Mocsáry, 1889, Ch. laeta Dahlbom, 1854, Ch. santschii Linsenmaier, 1959 and Ch. taurica Mocsáry, 1889 are newly added to the Iranian wasp fauna. The total number of Iranian Chrysis currently increased to 130 species and subspecies
