Abstract
A survey was conducted to identify the fungus gnats (Diptera: Mycetophilidae) in Kermanshah province (west of Iran) during 2010-2011. The specimens were collected from nine different localities. Adults were reared from the fruiting bodies of Agaric fungi. Five species are recorded for the first time from Iran: Mycetophila strigatoides (Lundrock), Allodia ornaticollis (Meigen), Rymosia pseudocretensis Burghele-Balacesco, Synplasta gracilis (Winnertz) and Sciophila eryngii Chandler. Eight host associations (gnats-fungi) are also reported for the first time. The diagnostic characters, host range and geographical distribution of each species are given.

Abstract
Specimens of springtails were collected from soil and leaf litter in the forests of Mazandaran province, north of Iran during 2016–2017. Three species were recorded in this country for the first time, Xenylla szeptyckii Skarżyński, Piwnik & Porco, 2018 (Hypogastruridae), Friesea espunaensis Arbea & Jordana, 1993 (Neanuridae) and Tomocerina minuta (Tullberg, 1877) (Tomoceridae). Detailed descriptions of these species are provided based on the materials collected from Mazandaran province, Iran.

In this study the biodiversity and relative abundance of Collembola was evaluated in two different ecosystems, citrus field and forest in Mazandaran province, Iran. Samples were carried out during 2016 and 2017. In each site, soil was sampled by a collecting core from 5×5 cm in surface area and a depth of 10 cm. Species richness, biodiversity and the indices of similarity were calculated. The results of T-Test showed that in two years (2016 and 2017), the values of Shannon-Wiener diversity and Simpson species diversity index were significantly different between sampling areas (Pvalue<0.05), but the values of Margalef richness and Pielou evenness index were not significantly (Pvalue˃0.05). In the year 2016, Shannon-Wiener index, Simpson index, Pielou evenness and Margalef species richness in Dasht-e Naz forest were 1.92 ± 0.1, 0.83 ± 0.03, 2.01 ± 0.2 and 0.94 ± 0.04 respectively, and in citrus field were 1.44 ± 0.11, 0.73 ± 0.02, 1.46 ± 0.37 and 0.9 ± 0.03 respectively. Also, in the year 2017, Shannon-Wiener index, Simpson index, Pielou evenness and Margalef species richness in Dasht-e Naz forest were 1.79 ± 0.05, 0.81 ± 0.08, 1.38 ± 0.25 and 0.94 ± 0.09 respectively, and in citrus field were 0.98 ± 0.22, 0.58 ± 0.08, 1.02 ± 0.35 and 0.95 ± 0.05 respectively. In general, the results showed that the abundance and biodiversity of Collembola in Dasht-e Naz forest was higher than in citrus field.

Abstract
The biodiversity of the Noctuidae, an economically important family of Noctuoidea which include major crop pests, is becoming well-identified nowadays in Iran due to the increased number of faunal expeditions. The two large subfamilies of Noctuidae namely Xyleninae Guenée, 1837 and Noctuinae Latreille, 1809 comprise the majority of Iran's noctuid moth fauna. Two species, Leucochlaena hoerhammeri (Wagner, 1931) and Dichagyris (Stenosomides) mansoura (Chrétien, 1911) members of Xyleninae and Noctuinae subfamilies, respectively, are recorded from Iran for the first time. This is also the first record of the subgenus Stenosomides Strand, 1942 from Iran. Both the external and genital characteristics of the newly recorded species are presented together with illustrations of the adults and their genitalia.

Abstract
Prior to this study eight species of Mesopolobus Westwood were recognized from Iran. In this study, one species namely M. aspilus (Walker) is newly recorded. An illustration of the external features of this species is provided. All known species from Iran were reviewed, the key to species and their geographical distribution in Iran is provided.

Abstract
Helicoverpa armigera (Hübner) is one of the major limiting factors in host plant production in the world and Iran. In this study, the effect of semi-artificial diets based on the seeds of different cultivars of white and red kidney bean, canola, soybean, and cowpea on eco-physiological parameters of H. armigera were investigated. The results showed that the shortest (22.71 days) and longest (28.94 days) development time of H. armigera was observed on cowpea cultivar Mashhad and canola cultivar Opera, respectively. The maximum immature mortality of H. armigera was on soybean cultivars M7 and Clark. Cowpea cultivar Mashhad had the highest r (0.299 day-1). The lowest level of proteolytic activity was 2.829 U mg-1 on soybean cultivar M7 for the 3rd instar larvae, 2.525 U mg-1 on soybean cultivars Crark for the 4th instar larvae, and 2.292 U mg-1 on soybean cultivar Sari for the 5th instar larvae. Nutritional indices of 3rd, 4th, 5th, 6th and whole instar larvae of H. armigera were affected by the artificial diets, i.e. seeds of different cultivars. According to the results, semi-artificial diets containing bean seeds (specifically cowpea cultivar Mashhad and white kidney bean cultivar Daneshkadeh) were more suitable than semi-artificial diets containing soybean and canola seeds for rearing of H. armigera.
