The Ichneumonidae fauna of Kerman province, Iran, was surveyed in April 2013 to June 2014. In total, 35 species belonging to 22 genera and eight subfamilies were collected and identified, of which Cryptus armator Fabricius, 1804; Enizemum schwarzi Diller, 1987 and Barichneumon gaullei Berthoumieu, 1903 are new records for thefauna of Iran. An updated list of Ichneumonid species for Kerman province is presented. These data can be useful for biological control programs.

The present study is based on the material collected from Alborz and Guilan provinces of Iran during March to November 2010 and 2011. Three species of the genus Platylabus Wesmael were collected and identified, of which Platylabus orbitalis (Gravenhorst, 1829) (Hym.: Ichneumonidae: Ichneumoninae, Platylabini) is newly recorded from Iran and the Middle East region. This study increases the number of known Iranian species of the tribe Platylabini and genus Platylabus to 12 and 5 species, respectively. An identification key to Iranian Platylabus, as well as a brief description and diagnostic characters of the new record species is provided.

In this survey the tribe Heresiarchini (Hymenoptera: Ichneumonidae, Ichneumoninae) of Alborz and Guilan provinces (Iran) was taxonomically studied. The specimens were collected using Malaise traps during March to November 2010. Three species including: Coelichneumon comitator (Linnaeus, 1758), Coelichneumon probator Horstmann, 2000 and Syspasis carinator (Fabricius, 1798) were identified of which C. probator is recorded for the first time from the Middle East and Iran. An updated checklist of Heresiarchini in Iran, as well as diagnostic characters of the new recorded species is presented.

The subfamily Metopiinae was taxonomically studied in Fars and Hormozgan provinces during 2011–2013. The specimens were collected by using Malaise traps and sweep net. Five species were collected and identified, of which three species are recorded for the first time from Iran: Colpotrochia cincta (Scopoli, 1763), Exochus suborbitalis Schmiedeknecht, 1924, and Metopius (Peltocarus) turcestanicus Clement, 1930. An identification key to the species and an updating checklist of Metopiinae of Iran, as well as zoogeographical notes are provided.

The tribe Platylabini (Hymenoptera: Ichneumonidae, Ichneumoninae) of Alborz, Guilan and Tehran provinces (North central Iran) was taxonomically studied. The specimens were collected using Malaise traps during March to November 2010–2011. Four species were identified including: Apaeleticus bellicosus Wesmael, 1845, Platylabus iridipennis Gravenhorst, 1829, Apaeleticus inimicus (Gravenhorst, 1820) and Linycus exhortator (Fabricius, 1787) of which A. inimicus and L. exhortator are recorded for the first time from Iran. An updated checklist of Platylabini in Iran, as well as diagnostic characters of the newly recorded species is presented.

This study is carried out to present new species records and new distributional data of the genera Casinaria Holmgren and Dusona Cameron (Hymenoptera: Ichneumonidae, Campopleginae) from Iran and also to provide the illustrated taxonomic notes on their diagnostic morphological characters. Specimens were collected using Malaise traps during 2013, 2015 and 2016 from Fars, Kerman and Mazandaran provinces. Four species present here as Casinaria kriechbaumeri (Costa, 1884); Casinaria trochanterator Aubert, 1960; Dusona cultrator (Gravenhorst, 1829) and Dusona erythrogaster (Förster, 1868). Two species i.e. D. cultrator and D. erythrogaster are newly reported from Iran. Data about distribution of D. rugifer and D. stygia in Iran as part of eastern Palaearctic fauna is updated to the western Palaearctic realm, based on collecting sites in Iran (D. rugifer from Golestan province and D. stygia from West Azerbaijan province). Available data on adult flight period of Iranian species of Casinaria and Dusona may indicate that five species are univoltine and the others are bivoltine.

To study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (Medicago scutellata cv. Robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (Sararood Dryland Agricultural Research Institute and Soil Fertility Research Station in Mahidasht) during 2009 growing season. The experimental treatments consisted of the two experimental sites with different climatic conditions and cultural systems (dry farming and irrigated systems), while the fertilizer treatments consisted of the control (no fertilizer), chemical fertilizer, biological fertilizer, and different combinations of chemical and biological fertilizing systems. The results showed that, in both irrigated and dry farming conditions, all fertilizing treatments increased macro- and micro-nutrients uptake over the control. The highest concentration of nutrient elements such as Nitrogen (3.82%), Potassium, (4.16 mg kg^-1), Iron (495 mg kg^-1) and Cu (60.8 mg kg^-1) were observed in integrated fertilizing treatments i.e. Nitrogen-fixing bacteria+Triple superphosphate. Application of integrated fertilizing treatments not only decreased the chemical fertilizer application (consequently, reducing the environmental pollutions), but it also enhanced forage quality in terms of higher macro- and micro-nutrients concentrations. According to the results of this study, it could be concluded that integrated fertilizing systems may be more efficient in dry farming agro-ecosystems than in irrigated systems.
