PARASITOIDS (HYMENOPTERA: CHALCIDOIDEA) OF THE SEED EATER WEEVIL, OXYSTOMA OCHROPUS (GERMAR) (COLEOPTERA: APIONIDAE) IN NORTHWESTERN IRAN

 To study Oxystoma ochropus (Germar, 1818) parasitoids on grass pea (Lathyrus sativus), weekly sampling was done inNamin, Ardabil Province, Iran, during 2011, and samples were transferred to laboratory conditions. In this study, fourparasitic wasps of three chalcidoid families were determined. These parasitoids were Eupelmus microzonus Förster,1860 (Eupelmidae), Eurytoma laserpitii Mayr, 1878 (Eurytomidae), Pteromalus chlorospilus (Walker, 1834) andPteromalus sequester Walker, 1835 (Pteromalidae). The species P. chlorospilus is a new record for Iranian fauna. Inaddition, all established trophic associations of the analyzed parasitoids with O. ochropus as their host are new for theinvestigated territory

TWO NEW HYMENOPTERAN FINDINGS IN SERBIA: DIPRION SIMILIS (DIPRIONIDAE) AS HOST AND ITS PARASITOID, MONODONTOMERUS DENTIPES (TORYMIDAE)

Two hymenopteran species are reported for the Serbian fauna. Diprion similis, from the family Diprionidae, served as a host for the parasitoid wasp Monodontomerus dentipes, from the family Torymidae. The specimens were collected from Mt. Zlatibor in western Serbia. The parasitoid specimens were reared from the pupal stadium of the host D. similis. &nbsp

Dendrosoter middendorffii (Ratzeburg, 1848) (Hymenoptera: Braconidae) a parasitoid of the fruit bark beetles in Iran

Abstract. A Braconidae species was obtained in a parasitoid rearing study performed with xylophagous pests in Ardebil province, northwest of Iran in 2012. These specimens were reared from the galleries of fruit bark beetle, Scolytus rugulosus (Muller) (Coleoptera: Scolytidae) and was identified as Dendrosoter middendorffii (Ratzeburg, 1848) (Hymenoptera: Braconidae, Doryctinae). Both the genus and the species are new records for Iran

New data on the distribution and hosts of Dinocampus coccinellae (Hymenoptera: Braconidae) in Iran

Three ladybird (Coleoptera: Coccinellidae) species, Coccinella septempunctata L., C. undecimpunctata L. and Hippodamia variegata (Goeze), were recorded as hosts of Dinocampus coccinellae (Schrank, 1802) (Hymenoptera: Braconidae) in the Iranian provinces of Khuzestan and Kurdistan. Coccinella undecimpunctata is a new host of this parasitoid in the country and both provinces are its new distribution records. The rates of emergence of D. coccinellae from field-collected C. septempunctata and H. variegata were very low (below 1%), while C. undecimpunctata was parasitized to a much higher degree (26.7%)

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

Effect of butanol, propanol and pentanol on the quality of cut Carnation cv. 'Nelson'

Abstract. Carnation (Dianthus caryophyllus L.) is one of the most popular cut flowers in the world with the most economical importance to flower industry. This plant is categorized among cut flowers and is very sensitive to ethylene. A symptom of senescence in carnation is curving of its petals inward. In this sense, with regards to the role of Alcoholic compounds in preventing bio-synthesis of ethylene as a senescence preventing agent and increasing the preservation of cut flowers postharvest, the effect of different treatments including propanol, butanol, and pentanol on carnation 'Nelson' was investigated at 4 levels (0%, 2%, 4%, and 6%) taken randomly. Variables such as vase life, fresh weight, chlorophyll a, petal protein, and ethylene were measured. Findings showed that treatments with 2% and 4% of propanol caused the longest vase life and the least decrease in fresh weight while, in comparison with distilled water, pentanol especially at 4% and 6% had a significantly negative effect on the amount of protein. Except for curing with pentanol, the amount of ethylene increased notably particularly in high densities and propanol at 4% showed the largest amount of chlorophyll a

New Records of Sceliotrachelinae (Hymenoptera: Platygastridae) in Iran

The hymenopteran family Platygastridae is a large group of parasitic wasps. A survey was carried out on the subfamily Sceliotrachelinae (Hym.: Platygastridae) in East Azerbaijan and Fars provinces of Iran. The genus Fidobia Ashmead and three species, Allotropa conventus Maneval, Fidiobia hofferi Kozlov and Isolia mongolica (Kozlov) are newly recorded from Iran. Illustrations of the morphological characteristics and their geographical distribution are presented

Tamarixia monesus (Walker) (Hym.: Eulophidae) parasitoid of Bactericera tremblayi (Wagner, 1961) (Hemiptera: Triozidae) in Iran

Bactericera tremblayi (Wagner, 1961) (Hemiptera: Triozidae) is reported on Brassica oleracea var. capitata (Brassicaceae) in northwestern Iran. Tamarixia monesus (Walker) (Hymenoptera: Chalcidoidea, Eulophidae) was reared for the first time on B. tremblayi, and compared with Tamarixia tremblayi, another parasitoid of B. tremblayi. This is a new record of T. monesus from the Middle East
